struts1 中 用form的validate验证,但是始终没进入action

Question

struts-config.xml 写道

form写道

public class UsersForm extends ActionForm
{
private Users users=new Users();

private String password2;//确认密码




/**
* Method validate
* @param mapping
* @param request
* @return ActionErrors
*/
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request)
{

ActionErrors errors=new ActionErrors();
if(null==this.users.getUserName() || "".equals(this.users.getUserName()))
{
System.out.println("kfsksk");
System.out.println(errors);//这值能取到
errors.add("errors.uname", new ActionMessage("errors.uname"));
System.out.println(errors.size());
}
else if(null==this.users.getPassword() || "".equals(this.users.getPassword()))
{
errors.add("errors.upass", new ActionMessage("errors.upass"));
}
else if(!(this.users.getPassword().equals(password2)) || this.users.getPassword()!=password2)
{
errors.add("errors.upass2", new ActionMessage("errors.upass2"));
}
else if(null==this.users.getUIdCode() || "".equals(this.users.getUIdCode()))
{
errors.add("errors.IDCard", new ActionMessage("errors.IDCard"));
}
else if(null==this.users.getUTel() || "".equals(this.users.getUTel()))
{
errors.add("errors.uTel", new ActionMessage("errors.uTel"));
}
else if(null==this.users.getUAddress() || "".equals(this.users.getUAddress()))
{
errors.add("erros.uAddress", new ActionMessage("erros.uAddress"));
}
else if(null==this.users.getUZip() || "".equals(this.users.getUZip()))
{
errors.add("errors.uZip", new ActionMessage("errors.uZip"));
}

if(!errors.isEmpty())
{
return errors;
}
return null;

}


/*
* Generated Methods
*/

public Users getUsers()
{
return users;
}


public void setUsers(Users users)
{
this.users = users;
}

public String getPassword2()
{
return password2;
}


public void setPassword2(String password2)
{
this.password2 = password2;
}

}

 

action代码

public ActionForward doAdd(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
    {
        response.setContentType("text/html;charset=UTF-8");
        request.setCharacterEncoding("UTF-8");
        
        System.out.println("fsfsa");//这里打印不出来，没进入action
        String str="";
        UsersForm usersForm = (UsersForm) form;
        Users u=usersForm.getUsers();
        System.out.println(u);
        boolean b=userBiz.isExists(u.getUserName());
        if(b)
        {
            request.getSession().setAttribute("msg", "该用户已存在，请重新注册！");    
            str="msg";
        }
        else
        {
            int i=userBiz.addUser(u);
            if(i>0)
            {
                request.getSession().setAttribute("msg", "添加用户成功！请登录！");  
                str="msg";
            }
            else
            {
                request.getSession().setAttribute("msg", "添加用户失败！请重新注册！");    
                str="msg";
            }
        }
        return mapping.findForward(str);
    }

 在页面都是通过<html:errors property=""/>的方式来取值，但是就是没进入action,直接跳转到在struts-config.xml文件中的action配置里面input的页面

麻烦大家帮我看看，谢谢啦！

那很明显是validate方法验证没有通过它才会返回input的呀，看一下你的验证方法里面哪里验证没有通过，一步一步去检查，调试。。逻辑判断思路一定要清晰，思考问题要全面。
