Question

我正在对现有应用进行修改。我的问题是即使表单提交验证失败，它仍然执行execute方法。

我的struts文件

        <result type="freemarker" name="input">/public/college_finder.html.ftl
        </result>
    </action>
</package>

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;
    }

为什么会发生这种情况的任何想法？出于某种原因，即使login.action失败，它仍然会向下发送成功并继续前进。

您的拦截器堆栈不包含“工作流”拦截器堆栈，这就决定了在验证失败时要做什么。

就此而言，它不包括“params”拦截器，这是在动作上设置参数的方式，因此它无论如何都不会工作。你不能随意删除拦截器 - 这是S2获得大部分功能的地方。 See the interceptor docs.

此外，您可以设置默认结果类型 - 如果大多数内容都是FreeMarker结果而不是一遍又一遍地输入，您可能希望这样做。

验证失败但它仍在struts2上执行
