Logger.getLogger(*.class)源码分析

//补偿：http://blog.csdn.net/anlina_1984/article/details/5313023
//方法
protected static Logger logger = Logger.getLogger(PropertiesConfigLocalLoader.class);

//进去这个
package org.apache.log4j;
public class Logger extends Category {

//只列出这个静态方法
static
public
Logger getLogger(Class clazz) {
return LogManager.getLogger(clazz.getName());
}

}

//进去这个
public class LogManager {
  //又只列出这一个静态方法
  public
  static 
  Logger getLogger(Class clazz) {
     // Delegate the actual manufacturing of the logger to the logger repository.
    return repositorySelector.getLoggerRepository().getLogger(clazz.getName());
  }

}

//进去这个
//卧槽一个接口，内容只有这么多
package org.apache.log4j.spi;
public interface RepositorySelector {

  /**
     Returns a {@link LoggerRepository} depending on the
     context. Implementors must make sure that a valid (non-null)
     LoggerRepository is returned.
  */
  public
  LoggerRepository getLoggerRepository();
}
    
//进去这个
//卧槽，又是接口
package org.apache.log4j.spi;
public interface LoggerRepository {

//就这样完结了
  public
  Logger getLogger(String name);

}
//然后呢？不明白
