spring mvc: 参数方法名称解析器(用参数来解析控制器下的方法)MultiActionController/ParameterMethodNameResolver/ControllerClassNameHandlerMapping
根据地址栏上的url的参数action来解析相应的控制器下的方法名，例如：
http://localhost:8080/项目名/user/index.html?action=remove
http://localhost:8080/项目名/user/*(可以是任意字符).html?action=remove
xml配置中会用到的类：
org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver
java-controller中，会用到：
org.springframework.web.servlet.mvc.multiaction.MultiActionController;
本例中用到了3个配置文件：web.xml, applicationContext, xxxx-servlet.xml
web.xml:
<!--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>

UserController.java代码
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 model = new ModelAndView("user_home");
model.addObject("message", "home");
return model;
}
public ModelAndView add(HttpServletRequest request, HttpServletResponse response)
{

return model;
}
public ModelAndView remove(HttpServletRequest request, HttpServletResponse response)
{
ModelAndView model = new ModelAndView("user_remove");
model.addObject("message", "remove");
return model;
}
}
jsp代码，大同小异:
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<%@ page isELIgnored="false" %>
