控制台的错误是
java.lang.IllegalArgumentException: Neither search() nor it's doXxx() equivalent is defined in action class com.inspur.report.web.action.UserModifyAction
但是明明search() 方法在呀

search() 方法定义时
好像不应该有参数
public class IllegalArgumentExceptionextends RuntimeException抛出的异常表明向方法传递了一个不合法或不正确的参数。

String search(UserInfo inputUserInfo)
参数？？
userId你直接从userDetailForm.action="UserModifyAction!search.action?userId="+__ 传递过去就行。search方法加参数做什么？
public String search(UserInfo inputUserInfo){}
改为：
public String search(){}我一般这样
userDetailForm.action="UserModifyAction!search";
这个只是实例，需要修改的，直接用肯定不行……
在页面用个hidden，值为userInfo.userId
在modify方法中，用js取得userId
然后再传值到后台
顶你，获得用户信息传个用户ID就行了。干嘛把个整个对象都传过去、
思路ls已经写得很明确的。PS:月饼拿来。
