Spring MVC-控制器（Controller）-属性方法名称解析器（Properties Method Name Resolver ）示例（转载实践）...

以下内容翻译自：https://www.tutorialspoint.com/springmvc/springmvc_propertiesmethodnameresolver.htm

说明：示例基于Spring MVC 4.1.6。

以下示例显示如何使用Spring Web MVC框架使用多操作控制器的属性方法名称解析方法。MultiActionController类有助于分别在单个控制器中将多个URL与其方法映射。

package com.tutorialspoint;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

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

public class UserController extends MultiActionController{
    
   public ModelAndView home(HttpServletRequest request, HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("user");
      model.addObject("message", "Home");
      return model;
   }

   public ModelAndView add(HttpServletRequest request, HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("user");
      model.addObject("message", "Add");
      return model;
   }

   public ModelAndView remove(HttpServletRequest request, HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("user");
      model.addObject("message", "Remove");
      return model;
   }
}

<bean class="com.tutorialspoint.UserController">
   <property name="methodNameResolver">
      <bean class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
         <property name="mappings">
            <props>
               <prop key="/user/home.htm">home</prop>
               <prop key="/user/add.htm">add</prop>
               <prop key="/user/remove.htm">update</prop>      
            </props>
         </property>
      </bean>
   </property>
</bean>

例如，使用上面的配置，如果是URI

1. /user/home.htm被请求，DispatcherServlet将请求转发到UserController home()方法。

2. /user/add.htm被请求，DispatcherServlet将请求转发给UserController add()方法。

3. /user/remove.htm被请求，DispatcherServlet将请求转发给UserControllerremove()方法。

首先，让我们使用Eclipse IDE，并按照以下步骤使用Spring Web Framework开发基于动态窗体的Web应用程序：

步骤	描述
1	创建一个名称的项目TestWeb包下com.tutorialspoint中所解释的Spring MVC - Hello World示例章节。
2	在com.tutorialspoint包下创建Java类UserController。
3	在jsp子文件夹下创建一个视图文件user.jsp。
4	最后一步是创建所有源和配置文件的内容并导出应用程序，如下所述。

UserController.java

package com.tutorialspoint;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

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

public class UserController extends MultiActionController{
    
   public ModelAndView home(HttpServletRequest request, HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("user");
      model.addObject("message", "Home");
      return model;
   }

   public ModelAndView add(HttpServletRequest request, HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("user");
      model.addObject("message", "Add");
      return model;
   }

   public ModelAndView remove(HttpServletRequest request, HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("user");
      model.addObject("message", "Remove");
      return model;
   }
}

TestWeb-servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:context="http://www.springframework.org/schema/context"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="

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

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

   <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"> 
      <property name="caseSensitive" value="true" />
   </bean>
   <bean class="com.tutorialspoint.UserController">
      <property name="methodNameResolver">
      <bean class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
         <property name="mappings">
            <props>
               <prop key="/user/home.htm">home</prop>
               <prop key="/user/add.htm">add</prop>
               <prop key="/user/remove.htm">update</prop>      
            </props>
         </property>
      </bean>
      </property>
   </bean>  
</beans>

user.jsp

<%@ page contentType="text/html; charset=UTF-8" %>
<html>
<head>
<title>Hello World</title>
</head>
<body>
   <h2>${message}</h2>  
</body>
</html>

完成创建源文件和配置文件后，导出应用程序。右键单击应用程序并使用Export > WAR File选项，并将您的TestWeb.war文件保存在Tomcat的webapps文件夹中。

现在启动您的Tomcat服务器，并确保您可以使用标准浏览器从webapps文件夹访问其他网页。现在尝试URL http://localhost:8080/TestWeb/user/add.htm，如果您的Spring Web应用程序的一切都很好，您应该会看到以下结果：
