验证失败，但仍在struts2上运行

我正在修改现有的应用程序。我的问题是，即使表单提交的验证失败，它仍然在执行execute方法

我的struts文件

你知道为什么会这样吗？由于某些原因，即使login.action失败，它仍然会发送成功返回并继续前进。

您的拦截器堆栈不包括“工作流”拦截器堆栈，它决定了在验证失败时要做什么

就这点而言，它不包括“params”拦截器，这是在动作上设置参数的方式，因此无论如何它都不会工作。您不能随意删除拦截器——S2就是在这里获得其大部分功能的

此外，您还可以设置一个默认的结果类型——如果大多数内容都是FreeMarker结果，您可能希望这样做，而不是反复输入

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;
    }
