  • spring mvc: 多动作控制器(Controller下面实现多个访问的方法)MultiActionController / BeanNameUrlHandlerMapping

    spring mvc: 多动作控制器(Controller下面实现多个访问的方法)

    比如我的控制器是UserController.java,下面有home, add, remove等多个方法

    访问地址:

    http://localhost:8080/项目名/user/add.html

    http://localhost:8080/项目名/user/home.html

    http://localhost:8080/项目名/user/remove.html

    需要用到的类:org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping

    配置文件中:

    org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping
    

      

    代码类中:

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

      

    目前有applicationContext.xml , springmvc-servlet.xml, web.xml三个配置文件

    具体来看代码:

    web.xml

    <web-app>
      <display-name>Archetype Created Web Application</display-name>  
      
      <!--配置文件路径-->
    <context-param>
     	<param-name>contextConfigLocation</param-name>
    	<param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>
    
    <!-- 字符过滤器 -->  
    <filter>
       <filter-name>encodingFilter</filter-name>
       <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
       <init-param>
           <param-name>encoding</param-name>
           <param-value>UTF-8</param-value>
       </init-param>  
    </filter>  
    <filter-mapping>  
        <filter-name>encodingFilter</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping> 
    
    <!-- 监听转发 -->
    <listener>
    	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
      <servlet>  
        <servlet-name>springmvc</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <load-on-startup>1</load-on-startup>  
    </servlet>  
    <servlet-mapping>  
        <servlet-name>springmvc</servlet-name>  
        <url-pattern>/</url-pattern>  
    </servlet-mapping>    
      
      
    </web-app>
    

      

    springmvc-servlet.xml

    </beans>  
    

      

    UserController.java

    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) {
    		ModelAndView mv = new ModelAndView("user_home");
    		mv.addObject("message", "home");
    		return mv;
    		
    	}
    	
    	
    	public ModelAndView add(HttpServletRequest request, HttpServletResponse response)
    	{
    		ModelAndView mv = new ModelAndView("user_add");
    		mv.addObject("message", "add");
    		return mv;
    	}
    	
    	
    	public ModelAndView remove(HttpServletRequest request, HttpServletResponse response)
    	{
    		ModelAndView mv = new ModelAndView("user_remove");
    		mv.addObject("message", "remove");
    		return mv;
    	}
    }
    

      

    jsp代码基本上差不多:

    <%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
    <%@ page isELIgnored="false" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>home</title>
    </head>
    <body>
    
    
    ${message}
    
    </body>
