Struts中的问题,ActionErrors这个can't be resolved to a type怎么办
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
// TODO Auto-generated method stub
ActionErrors errors = new ActionErrors();//存放错误消息对象
if(this.username==null||this.username.length()

Answer 1

建议你直接在验证用户名和密码的java类里继承ActionSupport,这样就可以直接使用ActionErrors了（this.addActionError("username","用户名错误").）
