Dropwizard Jersey 将请求/响应记录为错误，但为什么呢？

Question

我已经添加了这一行

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this 和this

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

这是一个日志示例：

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

ERROR  [11:17:41.615] [dw-31 - GET /helloworld] o.g.j.l.LoggingFeature -  1 * Server responded with a response on thread dw-31 - GET /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。应用程序不尝试记录任何内容并从java.util.Logger 的filter implementation of ContainerRequestFilter 和filter implementation of ContainerResponseFilter 接口返回，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。

我会同意这个实现被认为是糟糕的想法。同时期望更改为Level.OFF 根本不应该记录任何内容。 （至少不在ERROR下）

同时指定的详细程度是LoggingFeature.Verbosity.PAYLOAD_TEXT 所以整个

HTTP 标头的内容以及文本媒体的实体内容 类型已记录。

这是日志中 [ERROR] 消息之后的详细信息。
