Question

当我们重新加载resourceConfig时，我们正面临一个严重的问题，即我们的Jersey容器进入挂起状态。重新装载球衣容器的代码是 container.reload（ResourceConfig.forApplication（应用程序））;

我们无法找到此问题的根本原因，现在阻止了我们的发布。

我们正在使用球衣版本2.13。

我们收到的堆栈跟踪如下

Thread [DefaultMessageListenerContainer-1] (Suspended)  
owns: BufferedOutputStream  (id=3280)   
owns: PrintStream  (id=3281)    
owns: LoggingConfigurationHelper$2  (id=3282)   
owns: OutputStreamWriter  (id=3283) 
owns: ConsoleHandler  (id=3284) 
owns: RestfulConnector  (id=2845)

ApplicationHandler.<init>(Application, Binder) line: 285    
WebComponent.<init>(WebConfig, ResourceConfig) line: 311    
ServletContainer.reload(ResourceConfig) line: 578

我们也有一个嫌犯。在我们的一个REST资源中，我们返回List。我们在泽西日志中观察到以下警告，在此日志之后容器进入无法使用的状态。

WARNING: The following warnings have been detected: 
WARNING: Return type, java.util.List<SomeObject>, of method, public java.util.List<SomeObject> myResource.get(javax.ws.rs.core.UriInfo,java.lang.String,java.lang.String), is not resolvable to a concrete type.

任何帮助都将是一个很大的帮助！如果您需要更多信息，请告诉我。非常感谢。

我们可以通过配置日志记录来解决此问题。现在，日志将定向到文件。

Jersey ServletContainer在Errors.logErrors中记录错误时挂起
