Struts2 freemarker不提交表格字段

Question

这是如此基本，我不能相信我已经花了整整一天。

好吧，这是我的freemarker页面

bla bla bla 
<form name="message" action="[@s.url action="login"/]" onsubmit="return detectJavaScript();" method="post"> 
    <fieldset> 
     <legend>To begin, type your Graduation Report ID and password</legend> 
     <ol> 
      <li> 
       [@requiredInstruction /] 
       <label for="username" accesskey="U"> 
        [@requiredField /] <strong>Graduation Report ID:</strong> 
       </label> 
       <input id="username" name="username" size="10" tabindex="1" type="text" value="${username!''}" 
        [@errorStyle show=(fieldErrors?exists && fieldErrors["username"]?exists)/] /> 
       [@showFieldError field="username" /] 
      </li> 
      <li> 
       <label for="password" accesskey="P"> 
        [@requiredField /] <strong>Password:</strong> 
       </label> 
       <input id="password" name="password" size="10" tabindex="2" type="password" value="${password!''}" 
        [@errorStyle show=(fieldErrors?exists && fieldErrors["password"]?exists)/] /> 
       [@showFieldError field="password" /] 
      </li> 
bla bla bla 

和我的动作类

public class SubmitLoginAction { 
    public String username; 
    public String password; 


    private static Logger logger = Logger.getLogger(SubmitLoginAction.class); 

    public void validate() { 
     logger.debug("validate fired"); 

     logger.debug("username returned: " + username); 
     logger.debug("password returned: " + password); 

和我的支柱文件

      </result> 
     </action> 
    </package> 
</struts> 

不管我做什么它保持返回null了用户和传递。我试图与getter和setter，没有，似乎没有任何工作。

我认为这是一个开箱即用的struts。

Answer 1

这是，但你已经从箱子中删除它，并将其位移动。

你已经从默认拦截器堆栈中删除了“params”拦截器。 “params”拦截器是设置动作参数的参数。我在my answer to your previous post中提到过。

（除了无需继续键入“freemarker的”。）

（在一个侧面说明，我真的不推荐的公共属性，但它会工作，这取决于你Struts--版本IIRC的OGNL版本颠簸之一改变了。）
