struts 2.1.6 一个郁闷的问题

CodingBySea 2009-07-10 01:16:51

刚接触struts 2,做了一个简单的登陆程序（一个action,3个jsp页面)，运行时，struts 2有时会调用action的create方法，有时又调用index方法，有时又会调用execute方法。即便是在action配置中指定了method="execute"方法，仍然是一样的。？？？？
说明：如果form使用struts 标签,每次都调用execute方法，method属性不起作用，但会提示the resource required is not found for action or result success错误.使用html 的form标签时，绝大多数时间是调用create方法，配置method参数不起作用,但运行正常。

非常迷惑，请大侠们解惑!

开发平台：MyEclipse 6.0.1,jdk 6,tomcat 6.0
源程序：
1，LoginAction.java
public class LoginAction extends ActionSupport{
/**
*
*/
private static final long serialVersionUID = 1L;
private String user;
private String password;

public String create() throws Exception{
user = user+"--create_user";//加上“--create_user是为了测试",下同
password = password+"--create_password";
//user = new String(user.getBytes("ISO-8859-1"),"utf-8");
//String t = user;
return execute();
}

public synchronized String getUser() {
return user;
}

public synchronized void setUser(String user) {
this.user = user;
}

@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
return super.execute();
}

public String index() throws Exception {
user=user+"--index_user";
password=password+"--index_password";
return execute();
}
public synchronized String getPassword() {
return password;
}
public synchronized void setPassword(String password) {
this.password = password;
}
}
