关闭HttpClient日志中遇到的坑

最近在用HttpClient请求api的时候，控制台打印了太多无用的日志

14530 [main] DEBUG org.apache.http.headers - http-outgoing-0 >> POST /api/Run/GetRoadRun HTTP/1.1 
14530 [main] DEBUG org.apache.http.headers - http-outgoing-0 >> Content-Length: 43 
14530 [main] DEBUG org.apache.http.headers - http-outgoing-0 >> Content-Type: application/json 
14530 [main] DEBUG org.apache.http.headers - http-outgoing-0 >> Content-Encoding: UTF-8 

这些日志即会浪费性能也会覆盖有用的日志，查了官网，设置log4j，尝试在log4j.properties中这样设置

log4j.logger.httpclient.wire.header=DEBUG

log4j.logger.org.apache.commons.httpclient=DEBUG

并没有起作用，然后继续百度，查找到一篇关键的文章

才明白是SpringBoot使用logback框架的时候，commons-logging会自动转移到logback，所以需要设置与logback相关的配置文件。需要在resource路径下新建一个xml文件，添加下面的内容，设置里面的name和level就可以

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
  <!-- definition of appender STDOUT -->
  <appender name="org.apache.http.wire" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%-4relative [%thread] %-5level %logger{35} - %msg %n</pattern>
    </encoder>
  </appender>
 
  <root level="DEBUG">
    <!-- appender referenced after it is defined -->
    <appender-ref ref="org.apache.http.wire"/>
  </root> 
</configuration>

当把其中level="DEBUG"改为“WARN”就可以关闭这些日志了
