做cli命令行去调用webservice，该CXF客户端是一个普通java工程，需要使用log4j打日志。。
CXF默认使用java.util.logging作为默认的日志实现。
参考CXF官方文档：
http://cxf.apache.org/docs/debugging-and-logging.html
Using Log4j Instead of java.util.logging
As noted above, CXF uses the java.util.logging package by default. But it is possible to switch CXF to instead use Log4J . This is achieved through the use of configuration files. There are two options to bootstrapping CXF logging and each is listed below:
- Add the following system property to the classpath from which CXF is initialized:
-Dorg.apache.cxf.Logger=org.apache.cxf.common.logging.Log4jLogger
- Add the file META-INF/cxf/org.apache.cxf.Logger to the classpath and make sure it contains the following content:
org.apache.cxf.common.logging.Log4jLogger
Using SLF4J Instead of java.util.logging (since 2.2.8)
As noted above, CXF uses the java.util.logging package by default. But it is possible to switch CXF to instead use SLF4J . This is achieved through the use of configuration files. There are two options to bootstrapping CXF logging and each is listed below:
- Add the following system property to the classpath from which CXF is initialized:
-Dorg.apache.cxf.Logger=org.apache.cxf.common.logging.Slf4jLogger
- Add the file META-INF/cxf/org.apache.cxf.Logger to the classpath and make sure it contains the following content:
org.apache.cxf.common.logging.Slf4jLogger
简单描述一下就是：有两种方式实现在cxf中使用日志功能（本文采用的第二种方式）
1、在classpath中新建文件 META-INF/cxf/org.apache.cxf.Logger（此处本人走了不少弯路，刚开始 META-INF/cxf/org.apache.cxf.Logger 和log4j.propertis放 在src目录下，源码编译的class文件放在bin中。后来发现编译后目录中居然没有 org.apache.cxf.Logger文件，干脆直接把bin文件放入classpath中，直接把log4j.properties和META-INF/cxf/org.apache.cxf.Logger 建在这个位置 ）
2、在新建的文件中加上一行
org.apache.cxf.common.logging.Slf4jLogger
3、添加log4j需要的包： log4j.jar, common-logging.jar
4、直接把log4j.properties放在bin目录下
归根结底还是一个classpath的问题，但是刚开始的时候我把log4j.properties和 META-INF/cxf/org.apache.cxf.Logger放在src目录下应该是在classpath中的呀，不明白，请高手指教一下。。
