一、method参数
action
package com.pb.web.action;public class HourseAction { public String add(){ System.out.println("执行添加操作！"); return "success"; } public String update(){ System.out.println("执行更新操作！"); return "success"; } public String delete(){ System.out.println("执行删除操作！"); return "success"; }}struts.
<?DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"><struts> <!-- <constant name="struts.enable.DynamicMethodInvocation" value="false" /> <constant name="struts.devMode" value="false" /> <package name="default" namespace="/" extends="struts-default"> <default-action-ref name="index" /> <global-results> <result name="error">/error.jsp</result> </global-results> <global-exception-mappings> <exception-mapping exception="java.lang.Exception" result="error"/> </global-exception-mappings> <action name="index"> <result type="redirectAction"> <param name="actionName">HelloWorld</param> <param name="namespace">/example</param> </result> </action> </package> <include file="example.package name="default" namespace="/" extends="struts-default"><action name="hourse_add" class="com.pb.web.action.HourseAction" method="add"><result>addsuccess.jsp</result></action><action name="hourse_update" class="com.pb.web.action.HourseAction" method="update"><result>updatesuccess.jsp</result></action><action name="hourse_del" class="com.pb.web.action.HourseAction" method="delete"><result>deletesuccess.jsp</result></action></package></struts>
默认action配置
<!--默认action --><default-action-ref name="index" /><action name="index"><result>index.jsp</result></action>
二、使用动态方法调用
package com.pb.web.action;public class UserAction { public String add(){ System.out.println("执行添加操作！"); return "success"; } public String update(){ System.out.println("执行更新操作！"); return "success"; } public String delete(){ System.out.println("执行删除操作！"); return "success"; }}struts.
<package name="default" namespace="/" extends="struts-default"><action name="user" class="com.pb.web.action.UserAction"><result>userSuccess.jsp</result></action>
页面
<!-- 使用感叹号，调用指定方法--><form action="user!add"><input type="submit" value="添加"/></form><form action="user!update"><input type="submit" value="更新"/></form><form action="user!delete"><input type="submit" value="删除"/></form>
另一种写法
<!-- 使用感叹号，调用指定方法--><form action="user!add.action"><input type="submit" value="添加"/></form><form action="user!update.action"><input type="submit" value="更新"/></form><form action="user!delete.action"><input type="submit" value="删除"/></form>
三、使用通配符简化配置
action
package com.pb.web.action;public class HourseAction { public String add(){ System.out.println("执行添加操作！"); return "success"; } public String update(){ System.out.println("执行更新操作！"); return "success"; } public String delete(){ System.out.println("执行删除操作！"); return "success"; }}struts.
<constant name="struts.devMode" value="true" /><package name="default" namespace="/" extends="struts-default"><action name="hourse_*" class="com.pb.web.action.HourseAction" method="{1}"><result>{1}success.jsp</result></action></package>页面
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><!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>Insert title here</title></head><body><form action="hourse_add"><input type="submit" value="添加"/></form><form action="hourse_update"><input type="submit" value="更新"/></form><form action="hourse_delete"><input type="submit" value="删除"/></form></body></html>
