Java HttpClient - 减少调试输出

时间：2016-10-11 14:31:53

标签： java apache-httpclient-4.x

我需要加载测试我们一直在开发的应用程序，但我们的控制台日志经常被输出垃圾邮件。从早期的经验来看，我已经了解到System.out.println( )是一项相对昂贵的操作，所以我希望将打印减少到最低限度。

打印仅在应用程序尝试Http-post时发生，但我们每秒执行100次。我们使用Apache的HttpClient 4.5.2和HttpCore 4.4.5。该应用程序在Tomcat 7上运行。

我尝试了很多不同的解决方案：删除Tomcat阀门，设置Tomcat日志记录级别，设置-Djavax.net.debug = none，但似乎没有删除它。有谁知道导致这些输出的原因，以及如何关闭它们？

调试输出如下所示：

您可以查看：http://hc.apache.org/httpcomponents-client-ga/logging.html。

  

因此，HttpClient利用Commons Logging包提供的日志记录接口。 Commons Logging为各种日志包提供了一个简单的通用日志接口。通过使用Commons Logging，可以为各种不同的日志记录行为配置HttpClient。这意味着用户必须选择使用哪个日志框架。默认情况下，Commons Logging支持以下日志记录框架：
    - Log4J
    - java.util.logging
    - SimpleLog（Commons Logging内部）

您观察到的绝大多数输出​​实际上是＆＃34; wire＆＃34;记录（即实际的HTTP流量）：

  

有线日志用于记录执行HTTP请求时传输到服务器和从服务器传输的所有数据。有线日志使用org.apache.http.wire日志记录类别。只应启用此日志来调试问题，因为它会产生极大量的日志数据。

简而言之：找到使用的日志记录实现（例如log4J？），查找其配置文件，并减少org.apache.http(.wire)类别
