RESTEasy 异常：RESTEASY003770：响应已提交，无法处理异常
RESTEasy Exception: RESTEASY003770: Response is committed, can't handle exception
我的 RESTEasy 服务器出现奇怪的异常。当 return 发送给客户端的响应特别大时，就会发生这种情况。
异常发生在我的代码return将结果object转为RESTEasy之后，所以它都在RESTEasy层内。服务器是 TomCat.
较小的响应没问题，但较大的响应会触发错误。如果我 return JSON 或 XML 会发生这种情况，并且是由响应的大小触发的，而不是 object 中的内容，我正在 returning .
我四处搜索，但还没有找到任何有用的东西，此时我几乎迷路了....

更新：我居然又遇到了这种事！ Scott 在下面的回答涵盖了第一种情况，但第二次是由于为响应插入空值 header。 RESTEasy 在我插入它时接受了 null header 值，但是当它在退出我的代码后尝试序列化响应时爆炸了。
好的，现在已经经历过几次了 - 我亲眼目睹了这种行为，当 前端反向代理 出现问题时，如果你正在使用一个.例如，我在部署系统的地方和 运行 与不同用户一起使用 nginx 时看到了问题。临时目录的权限问题意味着在响应达到特定大小之前您可能看不到该问题。例如（它是一行，换行符是为了可见性）：

客户端似乎在响应完全发送给它之前关闭了连接，你能增加客户端超时时间然后检查
