json - 如果结果类型为 json，则 Struts2 Action 被调用两次

Question

我有一个包含 4 个操作方法的 Action 类。 所有四个操作操作方法都使用 json 结果。

通过日志记录和调试，我已经验证如果我调用操作方法1，操作方法2和3也会被调用。但不是4。最后再次调用action方法1，生成json结果

如果我将 Action 方法 1 的结果类型更改为具有 jsp 位置的默认调度程序，则仅调用 Action 方法 1。 (这是我想要的 json 结果的行为) 希望这是有道理的。

大家有什么想法吗？ 这个问题在这里被问到https://stackoverflow.com/questions/3767698/struts2-if-result-type-json-and-method-defined-then-all-methods-get-invoked

但是没有任何答复。 如果您需要更多信息，请告诉我。

        this.theEmailList = theEmailList;
    }

    public List<String> getTheEmailList() {
        return theEmailList;
    }
}

在这个操作类中，我尝试调用ajaxGetGoLiveEmailList，我得到的是首先调用ajaxGetGoLiveEmailList，然后ajaxGetChaserEmailList，然后ajaxGetAvailableEntityList，然后再次调用ajaxGetGoLiveEmailList。 ajaxToggleGroupBusinessSubscribed 被跳过。

如果我将ajaxGetGoLiveEmailList的结果注释更改为

results={@Result(location="something.jsp")

，仅调用 ajaxGetGoLiveEmailList。

当我查看配置浏览器时，所有操作映射都已正确配置，指向正确的方法调用。

JSON 插件可能会调用所有以“get”开头的方法，以尝试序列化它们以进行输出。尝试将您的方法重命名为其他名称。
