我有话说:
- 首先 内容比较多,篇幅比较长,有需要的可以耐心看完.
- 这个项目最开始是跟着狂神写下来的,附上狂神的详细视频链接及详细笔记:
17、ssm整合：Mybatis层_哔哩哔哩_bilibili
https://www.bilibili.com/video/BV1aE41167Tu?p=17&vd_source=b1036c3d2e010aa91f6ccb4fed6293ec狂神SSM教程- 专栏 -KuangStudy
"如果没有SSM框架的基础,建议先学完SSM的基础知识,这样听起来会容易很多".
- 跟着狂神写项目的期间没有遇到报错,但是写完之后觉得如果只是这样我并不满足,所以把我会的内容基本上都在这个项目中写出来了,我认为这是我的一种进步.
- 正常来说一个项目从开始到结束应该是一步一步来的,这里因为时间问题,无法一步一步展示.
- 虽然内容是整个项目的,但是建议还是再纯手打一遍,因为复制粘贴总会有些不必要的问题,哪怕正确的代码,复制粘贴可能还是有问题.
- 项目中的jsp页面可以先用vscode写一遍然后复制到jsp页面即可.
- 所谓框架,就是搭好一个架子,然后所有的操作都在框架的内部进行,不需要对框架进行其他的修改,而且一些操作交给Spring框架就可以帮你完成.
- 在写这个项目中遇到的一些问题:前段信息乱码,分页查询,大部分的js操作,有的时候可能并不是代码的问题...等等,但是好在坚持下来并逐一解决,这个项目在一些方面还是可以改进,比如多表查询,页面跳转动画,分页的信息,一些好看的css样式等.
- 知识没有白学的,学无止境.
1 项目简介
1.开发环境:
- JDK1.8; mysql8.0.31; mybatis3.5.2; mybatis-spring2.0.2; spring-webmvc及springjdbc都是5.1.9.RELEASE(个人认为目前是用的最舒服的一版)

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (`id` int(0) NOT NULL AUTO_INCREMENT COMMENT '用户id',`username` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NOT NULL COMMENT '用户名',`password` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NOT NULL COMMENT '用户密码\r\n',PRIMARY KEY (`id`) USING BTREE

新建Maven项目"Book"
1. 右键单击Book模块,选择框架支持,选择web应用程序(4.0版本);也可以在选择Maven项目是使用web-app模板,但是不推荐.
然后在项目中会多出来一个web的文件夹,注意:文件夹图标的小圆点一定要是亮着的,否则去Facet中调整选择到当前的项目.
2. 引入依赖
<?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>com.gcx</groupId><artifactId>Book</artifactId><version>1.0-SNAPSHOT</version><properties><maven.compiler.source>8</maven.compiler.source><maven.compiler.target>8</maven.compiler.target></properties><!-- 导入依赖--><dependencies><!--Junit单元测试--><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version></dependency><!--数据库驱动--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.31</version></dependency><!-- 数据库连接池 --><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.2</version></dependency><!--Servlet - JSP --><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version></dependency><dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version>2.2</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><!--Mybatis--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.5.2</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>2.0.2</version></dependency><!--Spring/SpringMVC--><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>5.1.9.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>5.1.9.RELEASE</version></dependency>

单击加号后选择库文件,全选,添加,应用即可
4. 配置Tomcat服务器
然后应用,确认即可
5. 测试Tomcat服务器能否正常运行
启动Tomcat后浏览器进入名为$Title$的index.jsp页面,并显示$END信息,表示Tomcat配置没问题
2.3 开始配置项目
1. 创建项目结构
java文件夹下属于源码文件,resources文件夹下属于资源文件,web下是前端的一些配置文件及页面.
2. 开始编写实体类
实体类名需要与数据库表名一致
Book
package com.gcx.pojo;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;@Data
@AllArgsConstructor
@NoArgsConstructor
@SuppressWarnings("all")
public class Book {private int bookid;private String bookname;private String author;private String publish;private String introduction;private Double price;private String booktype;
}User
package com.gcx.pojo;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {private String username;private String password;
}3. 编写持久层(dao层)
BookMapper接口
package com.gcx.dao;import com.gcx.pojo.Book;
import com.gcx.pojo.User;
import org.apache.ibatis.annotations.Param;import java.util.List;public interface BookMapper {// 增加一本书int addBook(Book book);// 删除一本书int deleteBookById(@Param("bookid") int id);// 更新一本书int updateBook(Book book);// 查询一本书Book queryBookById(@Param("bookid") int id);// 通过书名查询书籍,因为可能是一个集合,所以用ListList<Book> queryBookByName(@Param("bookname") String bookname);// 获取登录信息User findUserByNameAndPassword(User user);// 分页List<Book> findList();// 注册int adduser(User user);}因为要通过mybatis链接数据库,所以要配置它的核心配置文件: mybatis-config.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="classpath:spring-service.xml"/><import resource="classpath:spring-dao.xml"/><import resource="classpath:spring-mvc.xml"/>
</beans>有报错先不用管,是因为还没有配置对应的XML文件.
注意,这里上边会提示要配置应用程序的上下文
点击配置应用程序上下文,创建新的程序上下文
点击确定就可以了,进入项目设置,点击模块,查看是否配置成功
到此数据库链接完成,配置BookMapper.xml
<?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.gcx.dao.BookMapper"><insert id="addBook" parameterType="book">insert into book(bookname,author,publish,introduction,price,booktype)values(#{bookname},#{author},#{publish},#{introduction},#{price},#{booktype});</insert><delete id="deleteBookById" parameterType="int">delete from book where bookid =#{bookid};</delete><update id="updateBook" parameterType="book">update book set bookname=#{bookname},author=#{author},publish=#{publish},introduction=#{introduction},price=#{price},booktype=#{booktype}where bookid=#{bookid};</update><select id="queryBookById" resultType="book">select *from book where bookid = #{bookid};</select><select id="queryBookByName" resultType="book">select *from book where bookname = #{bookname};</select><select id="findUserByNameAndPassword" resultType="User">select *from userwhere username = #{username} and password = #{password};</select><select id="findList" resultMap="booksresultmap">select *from book</select><resultMap id="booksresultmap" type="com.gcx.pojo.Book"><id property="bookid" column="bookid" jdbcType="INTEGER"/><result property="bookname" column="bookname" jdbcType="VARCHAR"/><result property="author" column="author" jdbcType="VARCHAR"/><result property="publish" column="publish" jdbcType="VARCHAR"/><result property="introduction" column="introduction" jdbcType="VARCHAR"/><result property="price" column="price" jdbcType="DOUBLE"/><result property="booktype" column="booktype" jdbcType="INTEGER"/></resultMap><insert id="adduser" parameterType="user">insert into user(username,password)values (#{username},#{password});</insert>
</mapper>4. 编写业务层代码(service接口及实现类)
BookService
package com.gcx.service;import com.gcx.pojo.Book;
import com.gcx.pojo.User;
import com.github.pagehelper.PageInfo;public interface BookService {// 增加一本书int addBook(Book book);// 删除一本书int deleteBookById(int id);// 更新一本书int updateBook(Book book);// 查询一本书Book queryBookById(int id);// 通过书名查询书籍PageInfo<Book> queryBookByName(String bookname);// 获取登录信息User findUserByNameAndPassword(User user);// 分页查询PageInfo<Book> findList(Integer pageNum, Integer pageSize);// 注册int adduser(User user);
}BookServiceImpl
package com.gcx.service;import com.gcx.dao.BookMapper;
import com.gcx.pojo.Book;
import com.gcx.pojo.User;
import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import org.springframework.web.bind.annotation.RequestParam;import java.util.List;public class BookServiceImpl implements BookService {private BookMapper bookMapper;public void setBookMapper(BookMapper bookMapper) {this.bookMapper = bookMapper;}@Overridepublic int addBook(Book book) {return bookMapper.addBook(book);}@Overridepublic int deleteBookById(int id) {return bookMapper.deleteBookById(id);}@Overridepublic int updateBook(Book book) {return bookMapper.updateBook(book);}@Overridepublic Book queryBookById(int id) {return bookMapper.queryBookById(id);}@Overridepublic PageInfo<Book> queryBookByName(String bookname) {List<Book> list = bookMapper.queryBookByName(bookname);return new PageInfo<>(list);}@Overridepublic User findUserByNameAndPassword(User user) {return bookMapper.findUserByNameAndPassword(user);}@Overridepublic PageInfo<Book> findList(@RequestParam Integer pageNum,@RequestParam Integer pageSize) {// 每页显示多少数据if (pageSize== null){pageSize=5;}PageHelper.startPage(pageNum,pageSize);List<Book> list = bookMapper.findList();
// for (Books books : list) {
// System.out.println("书籍信息:"+books);
// }PageInfo PageInfo = new PageInfo(list);System.out.println("总页数:"+PageInfo.getPages());System.out.println("总记录数:"+PageInfo.getTotal());System.out.println("当前页数:"+PageInfo.getPageNum());System.out.println("当前页面记录数:"+PageInfo.getPageSize());return new PageInfo<>(list);}@Overridepublic int adduser(User user) {return bookMapper.adduser(user);}
}配置spring-service.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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/cache"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 http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd"><Context:component-scan base-package="com.gcx.service"/><bean id="BookServiceImpl" class="com.gcx.service.BookServiceImpl"><property name="bookMapper" ref="bookMapper"/></bean><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"/></bean></beans>配置上下文为applicationContext.xml.
5. 配置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:mvc="http://www.springframework.org/schema/mvc"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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">
<!-- 开启注解--><mvc:annotation-driven/>
<!-- 过滤静态资源--><mvc:default-servlet-handler/>
<!-- 扫描包下注解--><Context:component-scan base-package="com.gcx.controller"/>
<!-- 视图解析器--><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/jsp/"/><property name="suffix" value=".jsp"/></bean>
<!-- 配置拦截器--><mvc:interceptors><mvc:interceptor><mvc:mapping path="/book/**"/><bean class="com.gcx.interceptor.LoginInterceptor"/></mvc:interceptor></mvc:interceptors><!--文件上传配置--><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><!-- 请求的编码格式，必须和jSP的pageEncoding属性一致，以便正确读取表单的内容，默认为ISO-8859-1 --><property name="defaultEncoding" value="utf-8"/><!-- 上传文件大小上限，单位为字节（10485760=10M） --><property name="maxUploadSize" value="10485760"/><property name="maxInMemorySize" value="40960"/></bean>
</beans>如果在配置拦截器的地方报错,是因为还没有些拦截器的类,可以先创建一个不写内容.
配置上下文为applicationContext.xml
此时在Spring的模块中显示如下:
到这里,底层代码基本完成了.然后就是前后端的链接:
在mvc中是通过Servlet层的HttpServlet来实现的,在SpringMVC中,则是通过Controller层的添加注解或继承Controller接口来实现的.
6. BookController

// 3、 写出文件--输出流OutputStream out = response.getOutputStream();byte[] buff =new byte[1024];int index=0;
// 4、执行 写出操作while((index= input.read(buff))!= -1){out.write(buff, 0, index);out.flush();}out.close();input.close();return null;}
}7. LoginInterceptor拦截器
package com.gcx.interceptor;import org.springframework.web.servlet.HandlerInterceptor;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;public class LoginInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
/**
*
*因为是boolean 的返回类型,true代表可以通过拦截器,false代表被拦截器拦截,不能够通过
*/
// 设置编码格式request.setCharacterEncoding("UTF-8");HttpSession session = request.getSession();
// 通过Controller中的setAttribute保存的信息,在这里通过get获取到,如果userLoginInfo内不为空时可以通过if ( session.getAttribute("userLoginInfo")!=null){System.out.println("执行了登录拦截器=>111");return true;}
// getRequestURI().contains属于获取URL的地址,让URL进入到toLogin;Login;toregisterPage;register时可以通过if (request.getRequestURI().contains("toLogin")){System.out.println("执行了登录拦截器=>222");return true;}if (request.getRequestURI().contains("Login")){System.out.println("执行了登录拦截器=>333");return true;}if (request.getRequestURI().contains("toregisterPage")){System.out.println("执行了登录拦截器=>444");return true;}if (request.getRequestURI().contains("register")){System.out.println("执行了登录拦截器=>555");return true;}
// 判断当不满足以上条件使,都要被拦截器拦截,不能通过并重定向到Login.jsp页面request.getRequestDispatcher("/WEB-INF/jsp/Login.jsp").forward(request,response);return false;}
}
到这里,源码及配置文件层都已经完成
2.4 开始web层
首先,因为视图解析器中的前缀是WEB-INF下的jsp文件夹,所以在WEB-INF下新建jsp文件
1. 首先index.jsp(跳转进入页)

uplode是文件上传的位置
3 图片展示
1. index.jsp
2. 因为拦截器的原因在这里无论点击登录还是进入书籍页面都会被拦截到登录页面 Login.jsp
3. 想要进行注册,进入注册页面 register.jsp
点击注册或立即登录都会重新跳转到登录页面Login,jsp
4. 进行登录,使用的是user表里的用户信息
5. 点击登录进入allbook首页(第一页)
其中包括了Controller层内的大部分操作:新增,修改,删除,查询书籍,回到登录页,注销用户,分页显示,文件的上传及下载
6. 新增书籍页面 addbook.jsp
7. 修改书籍页面 updatebook.jsp
8. 书籍查询
9. 分页操作
10.文件上传
11. 下载
ok ,项目展示到此结束
