SpringMVC视图解析器

默认的BeanNameViewResolver

RedirectView 外部资源视图解析器
实体类创建如下：

public class BeanNameResolvetTest extends MultiActionController {
/*
    public String doFirst(){
        return "First";
    }*/
    public String doFirst(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {

        return "InnerReslover";
    }

    public String doSecond(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {

        return "OutResolver";
    }
}

xml的配置：

   <bean id="second" class="day05.BeanNameResolvetTest">
        <property name="methodNameResolver" ref="paramMethod"></property>
    </bean>

    <!--xml视图解析器-->
    <bean id="beanNameMethod" class="org.springframework.web.servlet.view.XmlViewResolver">
        <property name="location" value="classpath:myView.xml"></property>
    </bean>

    <!--外部资源-->
<bean id="OutResolver" class="org.springframework.web.servlet.view.RedirectView">
    <property name="url" value="https://www.jd.com"></property>
</bean>
    <!--参数配置式开发-->
    <bean id="paramMethod" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
       <property name="paramName" value="actionName"></property>
     </bean>

  <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="urlMap">
            <map>
                <entry key="/doFirst" value="second"></entry>
            </map>
        </property>
    </bean>

JstlView 内部资源视图解析器

实体类创建:

public class BeanNameResolvetTest extends MultiActionController {
/*
    public String doFirst(){
        return "First";
    }*/
    public String doFirst(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {

        return "InnerReslover";
    }

    public String doSecond(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {

        return "OutResolver";
    }
}

xml配置：

    <bean id="second" class="day05.BeanNameResolvetTest">
        <property name="methodNameResolver" ref="paramMethod"></property>
    </bean>

    <!--xml视图解析器-->
    <bean id="beanNameMethod" class="org.springframework.web.servlet.view.XmlViewResolver">
        <property name="location" value="classpath:myView.xml"></property>
    </bean>


    <!--内部资源-->
    <bean id="InnerReslover" class="org.springframework.web.servlet.view.JstlView">
        <property name="url" value="/Second.jsp"></property>
    </bean>


    <!--参数配置式开发-->
    <bean id="paramMethod" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
        <property name="paramName" value="actionName"></property>
    </bean>

    <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="urlMap">
            <map>
                <entry key="/doFirst" value="second"></entry>
            </map>
        </property>
    </bean>

XmlViewResolver视图解析器
  可以分离庞大的主配置文件的信息到多个小文件，方便主配置文件的管理和使用
具体实现功能代码如下：
实体类：

public class BeanNameResolvetTest extends MultiActionController {
/*
    public String doFirst(){
        return "First";
    }*/
    public String doFirst(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {

        return "InnerReslover";
    }

    public String doSecond(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {

        return "OutResolver";
    }
}

xml配置：

   <bean id="second" class="day05.BeanNameResolvetTest">
        <property name="methodNameResolver" ref="paramMethod"></property>
    </bean>

    <!--xml视图解析器-->
    <bean id="beanNameMethod" class="org.springframework.web.servlet.view.XmlViewResolver">
        <property name="location" value="classpath:myView.xml"></property>
    </bean>

    <!--参数配置式开发-->
    <bean id="paramMethod" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
       <property name="paramName" value="actionName"></property>
     </bean>

  <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="urlMap">
            <map>
                <entry key="/doFirst" value="second"></entry>
            </map>
        </property>
    </bean>
