[wwf06802136]

刚学Strut2遇到问题了~

package cn.action.org.action;

public class LoginAction {
	private String username;
	private String password;
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String exeute(){
		if(username.trim().equalsIgnoreCase("cena")&&password.equals("cena")){
			return "LoginSuc";
		}else{
			return "LoginFai";
		}
	}
}

请教具体代码

[Kevin-anycode]

不继承ActionSupport也是可以的

[zidasine]

public String exeute(){
方法名写错了应该是execute(）

[岁月之梦]

struts2用的是webwork的核心，你继承ActionSupport！然后里面覆盖
public class LoginAction2 extends ActionSupport{
@Override
public String execute() {
这里面就可以写代码！
}
}

当然LoginAction2 也可以不继承任何类
只是所有要用来访问的方法必须是public String 修饰的
execute()方法基本上是“必须”的

[ljsnake]

exeute写错了。。。
execute

这条信息显示的错误是不是因为你的struts.xml配置文件的文件名错啦,找不到该配置文件哇?
你修改下配置文件的名字试试...

[liaokunpeng818]

在form表单中的action="login.action"是这样的么?我感觉不用.action直接login就行
小弟只是刚学java说的有误还请指点,让我也明白下错误的解决办法..

execute() 方法是重载的父类方法
LoginAction你没有继承 ActionSupport
