整合SSM

环境要求

环境：

IDEA

MySQL 5.7.19

Tomcat 9

Maven 3.6

要求：

需要熟练掌握MySQL数据库，Spring，JavaWeb及MyBatis知识，简单的前端知识；数据库环境
创建一个存放书籍数据的数据库表
jdbc:mysql://localhost:3306?serverTimezone=GMT%2B8

 CREATE DATABASE `ssmbuild`;USE `ssmbuild`;DROP TABLE IF EXISTS `books`;CREATE TABLE `books` (`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',`bookName` VARCHAR(100) NOT NULL COMMENT '书名',`bookCounts` INT(11) NOT NULL COMMENT '数量',`detail` VARCHAR(200) NOT NULL COMMENT '描述',KEY `bookID` (`bookID`)) ENGINE=INNODB DEFAULT CHARSET=utf8INSERT  INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES (1,'Java',1,'从入门到放弃'),(2,'MySQL',10,'从删库到跑路'),(3,'Linux',5,'从进门到进牢');

1、 基本环境搭建
2、导入相关的pom依赖！


<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>org.example</groupId><artifactId>SSMbuild</artifactId><version>1.0-SNAPSHOT</version>

</project>

4、建立基本结构和配置框架！

com.xuyuan.pojocom.xuyuan.mappercom.xuyuan.servicecom.xuyuan.controller

mybatis-config.xml

    <?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration></configuration>

applicationContext.xml

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd"></beans>

Mybatis层编写

1、数据库配置文件 database.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123

、IDEA关联数据库

3、编写MyBatis的核心配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<typeAliases>
<typeAlias type="com.xuyuan.pojo.Books"/>
</typeAliases><mappers><mapper class="com.xuyuan.mapper.BookMapper"/></mappers>
</configuration>

编写数据库对应的实体类 com.xuyuan.pojo

使用lombok插件！

package com.xuyuan.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {private int bookID;private String name;private  int bookCounts;private String detail;}

编写Dao层的 Mapper接口！

package com.xuyuan.mapper;
import com.xuyuan.pojo.Books;
import org.apache.ibatis.annotations.Param;
import java.util.List;
public interface BookMapper {//增加一本书int addBook(Books books);//删除一本书int deleteBookById(@Param("bookId") int id);//修改一本书int updataBook(Books books);//查询一本书Books  queryById(@Param("bookId") int id);//查询全部的书List<Books>queryAllBooks();
}

编写接口对应的 Mapper.xml 文件。需要导入MyBatis的包；

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.xuyuan.mapper.BookMapper"><insert id="addBook" parameterType="Books">insert into ssmbuild.books (bookName,bookCounts,detail)values (#{bookName},#{bookCounts},#{detail});</insert><delete id="deleteBookById" parameterType="int">delete from  ssmbuild.books where bookId=#{bookId}
</delete><update id="updataBook" parameterType="Books">update  ssmbuild.books setbookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail}where bookID=#{bookID};</update><select id="queryById" resultType="Books">
select * from ssmbuild.books where bookId=#{bookId};</select><select id="queryAllBooks" resultType="Books">select * from ssmbuild.books;</select>
</mapper>

7、编写Service层的接口和实现类

**接口：**
package com.xuyuan.service;
import com.xuyuan.pojo.Books;
import org.apache.ibatis.annotations.Param;
import java.util.List;
public interface BooksService {//增加一本书int addBook(Books books);//删除一本书int deleteBookById(@Param("bookId") int id);//修改一本书int updataBook(Books books);//查询一本书Books  queryById(@Param("bookId") int id);//查询全部的书List<Books> queryAllBooks();
}

实现类：

package com.xuyuan.service;import com.xuyuan.mapper.BookMapper;
import com.xuyuan.pojo.Books;
import org.springframework.stereotype.Service;import java.util.List;
public class BookServiceImpl implements BooksService {private BookMapper bookMapper;public void setBookMapper(BookMapper bookMapper) {this.bookMapper = bookMapper;}public int addBook(Books books) {return bookMapper.addBook(books);}public int deleteBookById(int id) {return bookMapper.deleteBookById(id);}public int updataBook(Books books) {return bookMapper.updataBook(books);}public Books queryById(int id) {return bookMapper.queryById(id);}public List<Books> queryAllBooks() {return bookMapper.queryAllBooks();}
}

OK，到此，底层需求操作编写完毕！
Spring层

1、配置Spring整合MyBatis，我们这里数据源使用c3p0连接池；

2、我们去编写Spring整合Mybatis的相关的配置文件；spring-mapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd"><!-- 配置整合mybatis --><!-- 1.关联数据库文件 --><context:property-placeholder location="classpath:database.properties"/>
<!-- 2.连接池--><!--数据库连接池dbcp  半自动化操作  不能自动连接c3p0  自动化操作（自动的加载配置文件 并且设置到对象里面）--><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><!-- 配置连接池属性 --><property name="driverClass" value="${jdbc.driver}"/><property name="jdbcUrl" value="${jdbc.url}"/><property name="user" value="${jdbc.username}"/><property name="password" value="${jdbc.password}"/><!-- c3p0连接池的私有属性 --><property name="maxPoolSize" value="30"/><property name="minPoolSize" value="10"/><!-- 关闭连接后不自动commit --><property name="autoCommitOnClose" value="false"/><!-- 获取连接超时时间 --><property name="checkoutTimeout" value="10000"/><!-- 当获取连接失败重试次数 --><property name="acquireRetryAttempts" value="2"/></bean><!-- 3.配置SqlSessionFactory对象 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource"/><!-- 配置MyBaties全局配置文件:mybatis-config.xml --><property name="configLocation" value="classpath:mybatis-config.xml"/></bean><!-- 4.配置扫描Dao接口包，动态实现Dao接口注入到spring容器中 --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><!-- 注入sqlSessionFactory --><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/><!-- 给出需要扫描Dao接口包 --><property name="basePackage" value="com.xuyuan.mapper"/></bean>
</beans>

3、Spring整合service层

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/aophttps://www.springframework.org/schema/aop/spring-aop.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsd"><!-- 扫描service相关的bean --><context:component-scan base-package="com.xuyuan.service" /><!--BookServiceImpl注入到IOC容器中--><bean id="BookServiceImpl" class="com.xuyuan.service.BookServiceImpl"><property name="bookMapper" ref="bookMapper"/></bean><!-- 配置事务管理器 --><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><!-- 注入数据库连接池 --><property name="dataSource" ref="dataSource" /></bean><!--配置事务通知--><tx:advice id="txAdvice" transaction-manager="transactionManager"><!--给方法配置事务--><!--配置失误的传播性： new propagation=--><tx:attributes><tx:method name="*" propagation="REQUIRED"/></tx:attributes></tx:advice><!--配置事务切入--><aop:config><aop:pointcut id="txPonint" expression="execution(* com.xuyuan.mapper.*.*(..))"/><aop:advisor advice-ref="txAdvice" pointcut-ref="txPonint"/></aop:config>
</beans>

SpringMVC层
1、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"version="4.0"><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>/</url-pattern></servlet-mapping><filter><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!--Session过期时间--><session-config><session-timeout>15</session-timeout></session-config></web-app>

2、spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvchttps://www.springframework.org/schema/mvc/spring-mvc.xsd"><!-- 配置SpringMVC --><!-- 1.开启SpringMVC注解驱动 --><mvc:annotation-driven /><!-- 2.静态资源默认servlet配置--><mvc:default-servlet-handler/><!-- 3.配置jsp 显示ViewResolver视图解析器 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /><property name="prefix" value="/WEB-INF/jsp/" /><property name="suffix" value=".jsp" /></bean><!-- 4.扫描web相关的bean --><context:component-scan base-package="com.kuang.controller" />
</beans>

3、Spring配置整合文件，applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd"><import resource="spring-dao.xml"/><import resource="spring-service.xml"/><import resource="spring-mvc.xml"/></beans>

配置文件，暂时结束！Controller 和 视图层编写

1、BookController 类编写 ， 方法一：查询全部书籍

package com.xuyuan.controller;import com.xuyuan.pojo.Books;
import com.xuyuan.service.BooksService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;import java.util.List;@Controller
@RequestMapping("/book")
public class BookController {@Autowired@Qualifier("BookServiceImpl")private BooksService bookService;@RequestMapping("/allBook")public String list(Model model) {List<Books> list = bookService.queryAllBooks();model.addAttribute("list", list);return "allBook";}
}

2、编写首页 index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<!DOCTYPE HTML>
<html>
<head><title>首页</title><style type="text/css">a {text-decoration: none;color: black;font-size: 18px;}h3 {width: 180px;height: 38px;margin: 100px auto;text-align: center;line-height: 38px;background: deepskyblue;border-radius: 4px;}</style>
</head>
<body><h3><a href="${pageContext.request.contextPath}/book/allBook">点击进入列表页</a>
</h3>
</body>
</html>

3、书籍列表页面 allbook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %><%@ page contentType="text/html;charset=UTF-8" language="java" %><html>
<head><title>书籍列表</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body><div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>书籍列表 —— 显示所有书籍</small></h1></div></div></div><div class="row"><div class="col-md-4 column">
<a class="btn btn-primary" href="${pageContext.request.contextPath}/book/toAddBook">新增书籍</a></div></div><div class="row clearfix"><div class="col-md-12 column"><table class="table table-hover table-striped"><thead><tr><th>书籍编号</th><th>书籍名字</th><th>书籍数量</th><th>书籍详情</th><th>操作</th></tr></thead><tbody><c:forEach var="book" items="${list}"><tr><td>${book.bookID}</td><td>${book.bookName}</td><td>${book.bookCounts}</td><td>${book.detail}</td><td><a href="${pageContext.request.contextPath}/book/updata?id=${book.bookID}">修改</a>&nbsp; | &nbsp;<a href="${pageContext.request.contextPath}/book/deleteBook/${book.bookID}">删除</a></td></tr></c:forEach></tbody></table></div></div>
</div>

5、添加书籍页面：addBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title>新增书籍</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
</head>
<body>
<div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>新增书籍</small></h1></div></div></div><form action="${pageContext.request.contextPath}/book/addBook" method="post">
<%-- name必须要跟实体类的名字一致--%>书籍名称：<input type="text" name="bookName" required><br><br><br>书籍数量：<input type="text" name="bookCounts"required><br><br><br>书籍详情：<input type="text" name="detail"required><br><br><br><input type="submit" value="添加"></form>
</div>
</body>
</html>

6、BookController 类编写 ， 方法三：修改书籍

   //跳转到修改页面
@RequestMapping("/updata")public  String updataPaper(int id, Model model){Books books = bookService.queryById(id);model.addAttribute("QBooks",books);return "updataBook";}
//修改书籍@RequestMapping("/updatabook")public  String updataBook(Books books){System.out.println("修改了updataBook=》"+books);bookService.updataBook(books);return "redirect:/book/allBook";}

7、修改书籍页面 updateBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title>新增书籍</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
</head>
<body>
<div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>修改书籍</small></h1></div></div></div><form action="${pageContext.request.contextPath}/book/updatabook" method="post">
<%--出现的问题我们提交了修改的SQL请求，但是修改失败哦，初次考虑是事务问题看一下SQL能否执行成功 SQL失败修改为完成前端传递隐藏域问题--%><input type="hidden" name="bookID" value="${QBooks.bookID}"/><%-- name必须要跟实体类的名字一致--%>书籍名称：<input type="text" name="bookName" value="${QBooks.bookName}" required><br><br><br>书籍数量：<input type="text" name="bookCounts" value="${QBooks.bookCounts}" required><br><br><br>书籍详情：<input type="text" name="detail" value="${QBooks.detail}" required><br><br><br><input type="submit" value="修改"></form>
</div>
</body>
</html>

8、BookController 类编写 ， 方法四：删除书籍

//删除书籍
@RequestMapping("/deleteBook/{bookId}")
public String deleteBook(@PathVariable("bookId") int id){bookService.deleteBookById(id);return "redirect:/book/allBook";
}

控制器：

package com.xuyuan.controller;import com.xuyuan.pojo.Books;
import com.xuyuan.service.BooksService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;import java.awt.print.Book;
import java.util.List;@Controller
@RequestMapping("/book")
public class BookController {@Autowired@Qualifier("BookServiceImpl")private BooksService bookService;@RequestMapping("/allBook")public String list(Model model) {List<Books> list = bookService.queryAllBooks();model.addAttribute("list", list);return "allBook";}//跳转到添加书籍页面@RequestMapping("/toAddBook")public  String toAddPaper(){return "addBook";}//添加书籍的请求@RequestMapping("/addBook")public String addBook(Books books){System.out.println("addBook=>"+books);bookService.addBook(books);return "redirect:/book/allBook";}//跳转到修改页面
@RequestMapping("/updata")public  String updataPaper(int id, Model model){Books books = bookService.queryById(id);model.addAttribute("QBooks",books);return "updataBook";}
//修改书籍@RequestMapping("/updatabook")public  String updataBook(Books books){System.out.println("修改了updataBook=》"+books);bookService.updataBook(books);return "redirect:/book/allBook";}//删除书籍@RequestMapping("/deleteBook/{bookId}")public String deleteBook(@PathVariable("bookId") int id){bookService.deleteBookById(id);return "redirect:/book/allBook";}
}

配置Tomcat，进行运行！

到目前为止，这个SSM项目整合已经完全的OK了，可以直接运行进行测试！这个练习十分的重要，大家需要保证，不看任何东西，自己也可以完整的实现出来！

项目结构图

加一个查询
接口

   //按照名字查询
Books queryBookName(@Param("bookName") String bookName);

mapper.xml

<select id="queryBookName" resultType="Books">select *from ssmbuild.books where bookName=#{bookName};
</select>

业务层 实现类

    //按照名字查询
Books queryBookName( String bookName);
实现类public Books queryBookName(String bookName) {return bookMapper.queryBookName(bookName);

控制器

@RequestMapping("/queryBook")
public String queryBook(String queryBookName,Model model){Books books = bookService.queryBookName(queryBookName);List<Books> list =new ArrayList<Books>();list.add(books);if(books==null){bookService.queryAllBooks();model.addAttribute("erro","未查到");}model.addAttribute("list", list);return "allBook";
}

jsp前端

<div class="row"><div class="col-md-4 column">
<a class="btn btn-primary" href="${pageContext.request.contextPath}/book/toAddBook">新增书籍</a><a class="btn btn-primary" href="${pageContext.request.contextPath}/book/allBook">显示所有书籍</a></div><div class="col-md-8 column"><form class="form-inline" action="${pageContext.request.contextPath}/book/queryBook" method="post" style="float: right"><span style="color: #ff0000; font-weight: bold">${erro}</span><input type="text"  name="queryBookName" class="form-control"><input type="submit" value="查询" class="btn btn-primary"></form></div></div>
</div>

全部的AllBook

</div>
</body>
</html>

小结及展望

这个是同学们的第一个SSM整合案例，一定要烂熟于心！

SSM框架的重要程度是不言而喻的，学到这里，已经可以进行基本网站的单独开发。但是这只是增删改查的基本操作。可以说学到这里，大家才算是真正的步入了后台开发的门。也就是能找一个后台相关工作的底线。

或许很多人，工作就做这些事情，但是对于个人的提高来说，还远远不够！

我们后面还要学习一些 SpringMVC 的知识！
