将
ActionErrors error=new ActionErrors();
if ("login".equals(status)) {
if (this.id == null || "".equals(this.id)) {
error.add("id", new ActionMessage("id.null"));
}
}
该为
ActionErrors error=new ActionErrors();
if ("login".equals(status)) {
if (this.id == null || "".equals(this.id)) {
error.add("id", new ActionError("id.null"));
}
}
就可以了 ActionError比ActionMessage好用
