SpringMVC04controller中定义多个方法

public class MyController extends MultiActionController {

    // 新增 方法修饰符要是public
    public ModelAndView add(HttpServletRequest request,
            HttpServletResponse response) throws Exception {
        return new ModelAndView("/WEB-INF/jsp/success.jsp", "result", "add()");
    }

    // 修改
    public ModelAndView update(HttpServletRequest request,
            HttpServletResponse response) throws Exception {
        return new ModelAndView("/WEB-INF/jsp/success.jsp", "result",
                "update()");
    }

}

 1 public class MyController extends MultiActionController {
 2 
 3     // 新增 方法修饰符要是public
 4     public ModelAndView add(HttpServletRequest request,
 5             HttpServletResponse response) throws Exception {
 6         return new ModelAndView("/WEB-INF/jsp/success.jsp", "result", "add()");
 7     }
 8 
 9     // 修改
10     public ModelAndView update(HttpServletRequest request,
11             HttpServletResponse response) throws Exception {
12         return new ModelAndView("/WEB-INF/jsp/success.jsp", "result",
13                 "update()");
14     }
15 
16 }

创建对应的controller

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

        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">


  <!-- 配置一个处理器映射器 -->
  <bean  class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="urlMap">
       <map>
       <!--  
         因为我们的controller继承了MultiActionController，
         在MultiActionController有个    
     /** Delegate that knows how to determine method names from incoming requests */
         private MethodNameResolver methodNameResolver = new InternalPathMethodNameResolver();    
           根据我们的请求中参数找到对应方法 的解析器
          *：代表的就是我们的请求参数 也是对应的方法名
       -->
          <entry key="/user/*"  value="myController"/>
       </map>
    </property>
  </bean>

  
    <!-- 处理器 -->
    <bean id="myController" class="cn.bdqn.controller.MyController">
      <property name="methodNameResolver" ref="myResolver"></property>
    </bean>
</beans>

mvc核心xml文件的配置

使用我们自身设置的解析器来执行，不需要改变controller中的代码！只需要更改mvc核心xml文件

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

        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">


  <!-- 配置一个处理器映射器 -->
  <bean  class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="urlMap">
       <map>
       <!--  
         因为我们的controller继承了MultiActionController，
         在MultiActionController有个    
     /** Delegate that knows how to determine method names from incoming requests */
         private MethodNameResolver methodNameResolver = new InternalPathMethodNameResolver();    
           根据我们的请求中参数找到对应方法 的解析器
          *：代表的就是我们的请求参数 也是对应的方法名
       -->
          <entry key="/user/*"  value="myController"/>
       </map>
    </property>
  </bean>

  <!-- 设置解析器 -->
  <bean  id="myResolver" class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
    <property name="mappings">
     <props>
     <!-- 
      底层代码
     Set explicit URL to method name mappings through a Properties object.
      @param mappings Properties with URL as key and method name as value
    public void setMappings(Properties mappings) {
        this.mappings = mappings;
    }
      -->
       <prop key="/user/adds">add</prop>
       <prop key="/user/updates">update</prop>
     </props>
    </property>
  </bean>
  
    <!-- 处理器 -->
    <bean id="myController" class="cn.bdqn.controller.MyController">
    <!--需要更改父类的解析器引用 变成我们自已定义的解析器  -->
      <property name="methodNameResolver" ref="myResolver"/>
    </bean>

</beans>

mvc核心xml文件的设置

一旦我们设置了解析器，那么默认的

会执行我们设置的解析器

PropertiesMethodNameResolver

在浏览器中输入对应的url即可看到效果！

视图解析器

        return new ModelAndView("baidu");
    }

}

MyController代码

======================使用properties文件管理视图===========================

前台的页面还是使用的上面例子中的index.jsp

jd.(class)=org.springframework.web.servlet.view.RedirectView
jd.url=http://www.taobao.com

taobao.(class)=org.springframework.web.servlet.view.RedirectView
taobao.url=http://www.taobao.com

baidu.(class)=org.springframework.web.servlet.view.RedirectView
baidu.url=http://www.baidu.com

创建对应的properties文件

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

        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">



 <!--  参数名称 映射成  方法名称 -->
  <bean id="parameter"  class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver"/>
  

  
    <!-- 处理器 -->
<bean name="/myController" class="cn.bdqn.controller.MyController">
<property name="methodNameResolver" ref="parameter"/>
</bean>


<!-- 配置视图解析器   解析properties文件 -->
<bean class="org.springframework.web.servlet.view.ResourceBundleViewResolver">
<!--找到我们指定的properties文件  value就是代表的文件的名称  不需要加后缀名 -->
 <property name="basename"  value="myViews"/>
</bean>
   

</beans>

配置文件xml文件的内容

=====================xml文件中同时存在多个视图解析器的执行顺序======================

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

        http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">



 <!--  参数名称 映射成  方法名称 -->

    <!-- 处理器 -->
<bean name="/myController" class="cn.bdqn.controller.MyController">
<property name="methodNameResolver" ref="parameter"/>
</bean>

<!-- 如果是定义了多个 视图解析器  默认是按照在xml文件中的配置顺序 执行的
   如果不想使用默认的执行顺序  可以增加属性 order 设置一个正整数
   数值越小 优先级越高
 -->

   
   <!--  解析xml文件  -->
  <bean  class="org.springframework.web.servlet.view.XmlViewResolver">
   <property name="location" value="classpath:MyViews.xml"/>
   <property name="order" value="3"/>

<!-- 配置视图解析器   解析properties文件 -->
<bean class="org.springframework.web.servlet.view.ResourceBundleViewResolver">
