You are seeing this page because development mode is enabled. Development mode, or devMode, enables extra debugging behaviors and reports to assist developers. To disable this mode, set:
struts.devMode=false
in your WEB-INF/classes/struts.properties file. 描述:
login.jsp
<s:form action="login.action" method="post">
<s:textfield name="username" label="账号"></s:textfield><br/>
<s:textfield name="password" label="密码"></s:textfield><br/>
<s:submit value="提交"></s:submit>
</s:form>
LoginAction中的验证public void validate() {
super.validate();
if("".equals(this.getUsername())){
this.addFieldError("username", "对不起,用户名不能为空!");
}
if("".equals(this.getPassword())){
this.addFieldError("password", "对不起,密码不能为空!");
}
}
struts.xml中的配置
<action name="login" class="geekfly.action.LoginAction" method="login">
<result>/manager.jsp</result>
<result name="ERROR">/login.jsp</result>
<result name="input">/login.jsp</result>
</action>
解决办法:若在Struts2中使用ActionSupport类进行有刷新的验证,则必须在struts.xml中配置名为input的,不然会出现如上所诉的异常 /login.jsp
