Logger日志管理工具在代码中的引用

Java开发中几种日志工具的引用

1. org.apache.commons.logging.Log

    import org.apache.commons.logging.Log;
    import org.apache.commons.logging.LogFactory;
    private static final Log log = LogFactory.getLog(this.getClass());
   

2. org.slf4j.Logger

    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    private static Logger logger = LoggerFactory.getLogger(xxxClass.class);
   

3. log4j 2.x 版本：org.apache.logging.log4j.Logger

    import org.apache.logging.log4j.LogManager;
    import org.apache.logging.log4j.Logger;
    private static final Logger logger = LogManager.getLogger(xxxClass.class);
   

4. JDK 自带的 Logger

    import java.util.logging.Logger;
    private static final Logger logger = Logger.getLogger("serviceLogger");
   

   示例：创建一个基本服务类，里面放有Logger对象

    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
   
    /**
     * 创建一个基本Service类，存放Logger对象，
     * 基它业务类继承可直接拿来用
     * @author Rocky
     *
     */
    public class BaseService {
   
        /**
         * 日志对象
         */
        protected Logger logger = LoggerFactory.getLogger(getClass());
   
    }
