RESTEasy 异常：RESTEASY003770：响应已提交，无法处理异常

Question

我的 RESTEasy 服务器出现一个奇怪的异常。当向客户端返回特别大的响应时会发生这种情况。

异常发生在我的代码将结果对象返回给 RESTEasy 之后，所以它都在 RESTEasy 层内。服务器是 TomCat。

小的响应很好，但大的响应会触发错误。如果我返回 JSON 或 XML，就会发生这种情况，并且由响应的大小触发，而不是我返回的对象中的内容。

我已经四处搜索，但还没有找到任何有用的东西，现在几乎迷失了......

更新：我实际上再次发生了这种情况！斯科特在下面的回答涵盖了第一种情况，但第二次是由于为响应标头插入了一个空值。 RESTEasy 在我插入它时接受了 null 标头值，但在退出我的代码后尝试序列化响应时崩溃了。

好的，现在已经经历了几次 - 如果您使用的是前端反向代理，我亲眼目睹了这种行为前端反向代理。例如，我在使用 nginx 时遇到了问题，其中系统部署并与不同的用户一起运行。临时目录的权限问题意味着在响应达到一定大小之前您可能看不到该问题。例如（它是一行，换行是为了可见性）：

2017-04-20T17:46:40.03987 [nginx] 2017/04/20 13:46:40 [crit] 64537#0: 
  *14195 open() "/usr/local/var/run/nginx/proxy_temp/6/43/0000000436" 
  failed (13: Permission denied) while reading upstream, client: 10.0.0.1, 
  server: foo.bar.com, request: "GET /this/awesome/endpoint HTTP/1.1", 
  upstream: "http://127.0.0.1:9999/this/awesome/endpoint", host: "foo.bar.com"

似乎客户端在响应完全发送给它之前关闭连接，你可以增加客户端超时然后检查
