Dropwizard Jersey将请求/响应记录为错误，但为什么

Question

我添加了这一行

environment.jersey().register(new LoggingFeature(Logger
    .getLogger(LoggingFeature.class.getName()), Level.OFF, 
          LoggingFeature.Verbosity.PAYLOAD_TEXT, null));

在我的run(Configuration configuration, Environment environment)方法中查看这个和这个

如果Level设置为 OFF并且我的所有请求/响应消息都记录为 ERROR，我只会在日志中获取内容，但为什么是错误？

下面是日志的示例：

ERROR  [11:17:41.603] [dw-31 - GET /helloworld] o.g.j.l.LoggingFeature -  1 
* Server has received a request on thread dw-31 - GET /helloworld
1 > GET http://localhost:8080/helloworld

1 < 200

我的资源类：

@Path("/helloworld")
@Produces(MediaType.APPLICATION_JSON)
public class HelloWorldResource {
    public HelloWorldResource() { }
    @GET
    public Response helloWorld(){
        System.out.println("Hello World");
        return Response.ok().build();
    }
}

我的主要应用程序类：

public class ApiApplication extends Application<ApiConfiguration>{
public static void main(String[] args) throws Exception{
    new ApiApplication().run(args);
}
@Override
public void initialize(Bootstrap<ApiConfiguration> bootstrap) {
    // nothing to do yet
}
@Override
public void run(ApiConfiguration apiConfiguration, Environment environment) throws Exception {
    final TemplateHealthCheck healthCheck =
            new TemplateHealthCheck(apiConfiguration.getTemplate());
    environment.healthChecks().register("template", healthCheck);
    final HelloWorldResource helloWorldResource = new HelloWorldResource();
    final JerseyEnvironment jerseyEnvironment = environment.jersey();
    jerseyEnvironment.register(helloWorldResource);
    jerseyEnvironment.register(new LoggingFeature(Logger.getLogger(LoggingFeature.DEFAULT_LOGGER_NAME), Level.OFF, LoggingFeature.Verbosity.PAYLOAD_ANY, Integer.MAX_VALUE));
    }
}

您应该尝试将LoggingFeature更改为 -

environment.jersey().register(new LoggingFeature(
      Logger.getLogger(LoggingFeature.class.getName()), Level.FINE,
             LoggingFeature.Verbosity.PAYLOAD_TEXT, null));

由于当前日志记录设置为 Level.OFF .应用程序不会尝试记录任何内容，并从ContainerRequestFilter的过滤器实现和ContainerResponseFilter java.util.Logger接口的过滤器实现返回，其中log(LogRecord)方法被Logger的某个子类覆盖，该子类将级别修改为 ERROR。

我赞成认为这种实现被认为是糟糕的。同时期望更改为Level.OFF根本不应该记录任何内容。(至少不低于ERROR(

同时指定的详细程度LoggingFeature.Verbosity.PAYLOAD_TEXT因此整个

HTTP 标头的内容以及文本媒体的实体内容 记录类型。

这是日志中 [错误] 消息之后的详细信息。
