我的动作类代码

public void validate() { 
     logger.debug("validate fired"); 
Bla bla bla 
addFieldError("username","error"); 

     if (hasFieldErrors()) { 
      logger.debug("Field errors is true"); 
     } 
    } 

    public String execute() throws Exception { 
     logger.debug("execute firing"); 

     return result; 
    } 

任何想法，为什么会发生这种情况？由于某种原因，即使login.action失败了，它仍然会降低成功的回报率并向前发展。

您的拦截器堆栈不包含“工作流程”拦截器堆栈，它决定了验证失败时该怎么做。

对于这个问题，它不包括“params”拦截器，它是如何在动作上设置参数的，所以它永远不会工作。您不能随意删除拦截器 - 这是S2获得其大部分功能的地方。此外，您可以设置默认结果类型 - 如果大多数情况下都是FreeMarker结果，而不是一遍又一遍地输入，则可能需要这样做。
