这是资源文件
name.null = \u60a8\u63d0\u4ea4\u7684\u7528\u6237\u540d\u6216\u5bc6\u7801\u4e0d\u6b63\u786e!!
password.null = \u60a8\u63d0\u4ea4\u7684\u7528\u6237\u540d\u6216\u5bc6\u7801\u4e0d\u6b63\u786e!!
网友回复:好像那个验证有问题哦
网友回复:errors.add()
上面的方法是不是现在已经过期了 不能使用了哦
add（）；有删除线
网友回复:errors.add("name", new ActionMessage("name.null")); 设置的name的值。
怎么取得是 <html:errors property="username"> </html:errors> username的值呢？
网友回复:error.add("name",new ActionMessage("name.null"))中"name"改成"username";或将
<html:errors property="username"> </html:errors>中"username"改成"name"。
网友回复:
正解.
错误就在此.
