SpringMVC视图解析器

  AbstractController

 先创建一个MyAbstorctController类，并且让他继承AbstractController父类，并实现该父类中的方法.

public class MyAbstorctController extends AbstractController{
    protected ModelAndView handleRequestInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
          ModelAndView   mv=new ModelAndView();
          mv.setViewName("index");
        return mv;
    }
}

 abstorctcontroller.xml配置

        <!--处理器映射器-->
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
       <property name="urlMap">
           <map>
               <entry key="/hello.do" value="fistController"></entry>
           </map>
       </property>
   </bean>

        <!--注册处理器-->
<!--<bean id="/hello.do" class="cn.happy.controller.Onecontriller"></bean>-->
<bean id="fistController" class="cn.happy.controller.MyAbstorctController">
          <property name="supportedMethods">
              <set>
                  <value>POST</value>
                  <value>GET</value>

              </set>
          </property>
    </bean>

        <!--视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/"></property>
<property name="suffix" value=".jsp"></property>
</bean>

MultiActionController类的实现方式有三种：

首先创建MyMutiActionController类并继承MultiActionController类，自定义方法名

public class MyMutiActionController extends MultiActionController {
    public ModelAndView insert(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        ModelAndView   mv=new ModelAndView();
        mv.setViewName("insert");
        return mv;
    }
    public ModelAndView delete(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        ModelAndView   mv=new ModelAndView();
        mv.setViewName("delete");
        return mv;
    }
}

（一）multiactioncontroller.xml配置，默认的方法解析器

     <!--处理器映射器-->
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="urlMap">
        <map>
            <entry key="/*.do" value="mutiactioncontroller"></entry>
        </map>
    </property>
</bean>

     <!--注册处理器-->
<bean id="mutiactioncontroller" class="cn.happy.controller.MyMutiActionController">
 </bean>

     <!--视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
 <property name="prefix" value="/WEB-INF/"></property>
 <property name="suffix" value=".jsp"></property>
 </bean>

（二）propertiesMrthodNameresolver.xml配置

     <!--处理器映射器-->
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
       <property name="urlMap">
           <map>
               <entry key="/*.do" value="mutiactioncontroller"></entry>
           </map>
       </property>
   </bean>

<!--属性方法名称解析器-->
<bean id="propertyNameResoler"  class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
        <property name="mappings">
            <props>
                <prop key="/first.do">insert</prop>
                <prop key="/second.do">delete</prop>
            </props>
        </property>
    </bean>

        <!--注册处理器-->
<bean id="mutiactioncontroller" class="cn.happy.controller.MyMutiActionController">
        <property name="methodNameResolver" ref="propertyNameResoler"></property>
    </bean>

        <!--视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/"></property>
    <property name="suffix" value=".jsp"></property>
    </bean>

（三）propeterMrthodNameresolver.xml配置，参数方法解析器

  <!--处理器映射器-->
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
       <property name="urlMap">
           <map>
               <entry key="/hello.do" value="mutiactioncontroller"></entry>
           </map>
       </property>
   </bean>

<!--属性方法名称解析器-->
<bean id="properterNameResoler"  class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
        <property name="paramName" value="actionName"></property>
    </bean>

        <!--注册处理器-->
<bean id="mutiactioncontroller" class="cn.happy.controller.MyMutiActionController">
        <property name="methodNameResolver" ref="properterNameResoler"></property>
    </bean>

        <!--视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/"></property>
    <property name="suffix" value=".jsp"></property>
    </bean> 

    视图解析器： 

  先创建一个MyViewResoler类，并继承MultiActionController类，自定义两个方法名。

public class MyViewResoler extends MultiActionController {
    public ModelAndView insert(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        ModelAndView   mv=new ModelAndView();
        mv.setViewName("innserView");
        return mv;
    }
    public ModelAndView inserts(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        ModelAndView   mv=new ModelAndView();
        mv.setViewName("jd");
        return mv;

    }
}

创建ViewResoler.xml配置
