Jersey资源从Jersey客户端接收重复请求

Question

我们最近在服务器和客户端上从Jersey 1.x升级到Jersey 2.22.1.我们现在间歇地看到泽西岛将提出/接收两个请求.

• 通过间歇性我的意思是几千个请求中的每一个.
• 我们从未使用Jersey 1.x遇到过这个问题.
• 我不清楚这是客户端还是服务器端的问题.
• 在客户端,日志仅显示单个 POST请求和响应(请参阅下面的代码段)
• 在服务器端,日志显示两个 POST请求和响应(请参阅下面的代码段)

我可以通过在此客户端POST请求上循环数千次来重现它.每个请求都会发送一个唯一的"名称",该名称将保留在服务器上.我知道当我遇到一个唯一的约束违规试图保持两次相同的"名称"时,我们收到了一个重复的请求.我排除了代码的其他部分,因为日志确认Jersey正在接收两个相同"名称"的POST请求

我已在服务器上的org.glassfish包中启用了跟踪日志记录,并在客户端上注册了LoggingFilter().

客户端仅显示1个POST请求和响应:

服务器显示两个相同"名称"的POSTS:

如果此处有任何其他可能相关的配置信息,请告诉我.我们使用Tomcat 7.x和Jackson进行序列化/反序列化

Answer 1

我遇到了同样的问题，并且无法复制这个问题。您是否尝试关闭 ClientResponse 流？让我知道结果如何。

Client client = new Client();
WebResource resource = client.resource(restUrl);
final ClientResponse response = resource.get(ClientResponse.class);
response.close();
