struts2的执行顺序:
1.表单提交给action(如loginAction)
<a href="testAction.action?id=11">action跳转测试</a>
<form action="flagSaveActionFlag.action" method="post">
2.到strus.xml
<package name="com.StrutsDemo.Action" extends="struts-default"> <!-- 用户管理的Action --> <action name="*Action" class="com.StrutsDemo.Action.UserInfoAction" method="{1}"> <result name="success">/ook.jsp</result> <result name="error">/error.jsp</result> <result name="userview">/userview.jsp</result> <result name="index" type="redirect">/flagTestActionFlag.action?id=${id}</result> </action> <action name="*ActionFlag" class="com.StrutsDemo.Action.FlagAction" method="{1}"> <result name="success">/ook.jsp</result> <result name="error">/error.jsp</result> </action> </package>
3.testAction.action在struts2.xml中找到“*Action”,再找到类com.StrutsDemo.Action.UserInfoAction,然后再到类中找test()方法;
public class UserInfoAction { //其他方法 public String test(){ //方法内容 return "index"; }
4.再到struts2.xml中找到“*Action”下的<result name="index" type="redirect">/flagTestActionFlag.action?id=${id}</result>
继续按3跳转到struts2.xml中的“*ActionFlag”,再找到类com.StrutsDemo.Action.FlagAction下的方法flagTest(),再同3
