Spring MVC 的xml一些配置

1.可以自动加载注解驱动，通过注解找到对应Controller

    <!-- spring MVC 注解驱动 --><mvc:annotation-driven></mvc:annotation-driven><!-- 配置自动扫描包 --><context:component-scan base-package="com.cc8w.Controller"></context:component-scan><!-- 配置视图解析器 --><bean  class="org.springframework.web.servlet.view.InternalResourceViewResolver">  <property name="prefix" value="/WEB-INF/view/"></property>  <property name="suffix" value=".jsp"></property>  </bean>

package com.cc8w.Controller;import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;@Controller
@RequestMapping("/HelloWorld")
public class HelloWorld {@RequestMapping("/hi.do")public String hi(String names,Model model){System.out.println("hi.dodo");model.addAttribute("hi", "hi123456");return "hi";}
}

显示结果正确.

2.配置HandlerMapping,根据beanName找到对应Controller

web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"><display-name>Spring-web02</display-name><welcome-file-list><welcome-file>index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file>index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file>default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list><!-- The front controller of this Spring Web application, responsible for handling all application requests --><servlet><servlet-name>springDispatcherServlet</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><!-- Map all requests to the DispatcherServlet for handling --><servlet-mapping><servlet-name>springDispatcherServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping>
</web-app>

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"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd"><!-- 配置HandlerMapping 根据beanname找到对应Controller --><bean class="org.springframework.web.servlet.mvc.support.ControllerBeanNameHandlerMapping"></bean><!--配置beanname找到对应的Controller --><bean name = "/dogcontrollerdog" class = "com.cc8w.Controller.Dog"></bean><!-- 配置视图解析器 --><bean  class="org.springframework.web.servlet.view.InternalResourceViewResolver">  <property name="prefix" value="/WEB-INF/view/"></property>  <property name="suffix" value=".jsp"></property>  </bean> </beans>

测试类(这里一定要继承org.springframework.web.servlet.mvc.AbstractController接口)

package com.cc8w.Controller;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;public class Dog extends AbstractController {public Dog(){System.out.println("13213"); }@Overrideprotected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception {// TODO Auto-generated method stubSystem.out.println("456--访问到了---"); ModelAndView mav = new ModelAndView("dog");mav.addObject("hi", "467 th");return mav;}
}

模版目录和结果

3.配置HandlerMapping,根据URL找到对应Controller(主要是applicationContext.xml或<bean-name>-Servlet.xml的区别)

<?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:aop="http://www.springframework.org/schema/aop"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd"><!-- 配置HandlerMapping 根据简单URL找到对应Controller --><bean class = "org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"><property name="mappings"><props><prop key="/dogcontroller">dog</prop></props></property></bean><!--bean类 --><bean id = "dog"  class = "com.cc8w.Controller.Dog"></bean><!-- 配置视图解析器 --><bean  class="org.springframework.web.servlet.view.InternalResourceViewResolver">  <property name="prefix" value="/WEB-INF/view/"></property>  <property name="suffix" value=".jsp"></property>  </bean> </beans>

上面的类，这个spring MVC配置文件，可以找到控制器，就不截结果了.

4.配置HandlerMapping，通过控制器类名访问Controller，访问时类名首字母小写小写

<?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:aop="http://www.springframework.org/schema/aop"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd"><!-- 配置HandlerMapping 通过控制器类名访问Controller，访问时类名首字母小写 --><bean class = "org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"></bean><!--bean类 --><bean  class = "com.cc8w.Controller.Dog"></bean><!-- 配置视图解析器 --><bean  class="org.springframework.web.servlet.view.InternalResourceViewResolver">  <property name="prefix" value="/WEB-INF/view/"></property>  <property name="suffix" value=".jsp"></property>  </bean> </beans>

http://localhost:8080/Spring-web02/dog 这样访问...
