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.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!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.xml"/> --> <!-- Add packages here -->
<constant name="struts.devMode" value="true" />
<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.xml
<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.xml
<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

pageEncoding="UTF-8"%>
