java - 如何在 Dropwizard 1.0.2 中使用 LoggingFeature 打印服务器响应？

Question

以下代码导致在 Dropwizard 0.9.2 和 1.0.2 中打印 JSON 服务器响应:

return ClientBuilder
        .newBuilder()
        .build()
        .register(new LoggingFilter(Logger.getLogger(LoggingFilter.class.getName()), true))

例如:

Oct 21, 2016 7:57:42 AM org.glassfish.jersey.filter.LoggingFilter log
INFO: 1 * Client response received on thread main
1 < 401
1 < Connection: keep-alive
1 < Content-Length: 49
1 < Content-Type: text/plain
1 < Date: Fri, 21 Oct 2016 07:57:42 GMT
1 < Server: […]
1 < WWW-Authenticate: Basic realm="[…]"
Credentials are required to access this resource.

javax.ws.rs.NotAuthorizedException: HTTP 401 Unauthorized

但是，LoggingFilter 在 1.0.2 中已被弃用，建议改用 LoggingFeature。在documentation of LoggingFeature它说默认的详细程度是 LoggingFeature.Verbosity.PAYLOAD_TEXT，所以我期待以下代码仍然在 Dropwizard 1.0.2 中打印 JSON 服务器响应:

return ClientBuilder
        .newBuilder()
        .build()
        .register(new LoggingFeature(Logger.getLogger(getClass().getName())))

相反，日志仅包含以下内容:

javax.ws.rs.NotAuthorizedException: HTTP 401 Unauthorized

Answer 1

这就是诀窍:

new LoggingFeature(Logger.getLogger(getClass().getName()), Level.OFF, LoggingFeature.Verbosity.PAYLOAD_TEXT, 8192)

我猜测客户端中的日志记录功能就像一个过滤器，而不是预期的包含。
