SpringMVC03 ParameterMethodNameResolver(参数方法名称解析器) And XmlViewResolver(视图解析器)

　　参数方法名称解析器

1.配置依赖包

<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/maven-v4_0_0.xsd">

    <parent>

        <artifactId>SpringMVC</artifactId>

        <groupId>cn.happy</groupId>

        <version>1.0-SNAPSHOT</version>

    </parent>

    <modelVersion>4.0.0</modelVersion>

    <artifactId>SpringMVC03ViewResolver</artifactId>

    <packaging>war</packaging>

    <name>SpringMVC03ViewResolver Maven Webapp</name>

    <url>http://maven.apache.org</url>

    <properties>

        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

        <!--spring对应的版本号-->

        <spring.version>4.2.1.RELEASE</spring.version>

    </properties>

    <dependencies>

        <dependency>

            <groupId>junit</groupId>

            <artifactId>junit</artifactId>

            <version>4.0</version>

            <scope>test</scope>

        </dependency>

        <!--引入需要的spring 核心jar-->

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-context</artifactId>

            <version>${spring.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-core</artifactId>

            <version>${spring.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-beans</artifactId>

            <version>${spring.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-expression</artifactId>

            <version>${spring.version}</version>

        </dependency>

        <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc -->

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-webmvc</artifactId>

            <version>${spring.version}</version>

        </dependency>

        <!--引入需要的jstl jar-->

        <dependency>

            <groupId>javax.servlet</groupId>

            <artifactId>jstl</artifactId>

            <version>1.2</version>

        </dependency>

    </dependencies>

    <build>

        <finalName>SpringMVC03ViewResolver</finalName>

    </build>

</project>

　　2.配置中央调度器(web.xml）

<!DOCTYPE web-app PUBLIC

        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

        "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>

    <display-name>Archetype Created Web Application</display-name>

    <servlet>

        <servlet-name>springmvc</servlet-name>

        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <init-param>

            <param-name>contextConfigLocation</param-name>

            <param-value>classpath:spring-controller.xml</param-value>

        </init-param>

        <load-on-startup>1</load-on-startup>

    </servlet>

    <servlet-mapping>

        <servlet-name>springmvc</servlet-name>

        <url-pattern>/</url-pattern>

    </servlet-mapping>

</web-app>

还有一个视图解析器——BeanNameViewResolver

　　3.配置处理器映射器(Spring-controller.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/beans

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

    <!--映射器-->

    <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">

        <property name="mappings">

            <props>

                <prop key="/hello.do">myPropertiesController</prop>

            </props>

        </property>

    </bean>

    <!--视图解析器：XmlViewResolver-->

    <bean class="org.springframework.web.servlet.view.XmlViewResolver">

        <property name="location" value="classpath:myView.xml"/>

    </bean>

    <!--参数方法名称解析器-->

    <bean id="parameterMethodNameResolver"

          class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">

        <property name="paramName" value="actionName"/>

    </bean>

    <!--控制器配置-->

    <bean id="myPropertiesController" class="cn.happy.controller.MyMultiController">

        <property name="methodNameResolver" ref="parameterMethodNameResolver"/>

    </bean>

</beans>

　　4.配置视图解析器（MyView.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/beans

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

    <!--外部资源视图对象-->

    <bean id="jd" class="org.springframework.web.servlet.view.RedirectView">

        <property name="url" value="https://www.jd.com"/>

    </bean>

    <!--内部资源视图对象-->

    <bean id="internal" class="org.springframework.web.servlet.view.JstlView">

        <property name="url" value="/second.jsp"/>

    </bean>

</beans>

　　5.处理器（MyMultiController）

import org.springframework.web.servlet.ModelAndView;

import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

public class MyMultiController extends MultiActionController {

    public String doFirst(HttpServletRequest request, HttpServletResponse response) {

        System.out.println("doFirst");

        return "jd";

    }

public ModelAndView doSecond(HttpServletRequest request, HttpServletResponse response) {

        System.out.println("doSecond");

        return new ModelAndView("internal");

    }

}

　　6.视图（second.jsp）

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>

<head>

    <title>Title</title>

</head>

<body>

<h2>doSecond</h2>

</body>

</html>

测试结果：

当输入这行路径时：就会跳到下个页面
