### 本测试案例使用的是SpringBoot环境 ###

### 1.配置文件 ###

    logging.config=classpath:logback.xml
    
    
    server.port=8700
    # session time 30
    server.session-timeout=60

### logback.xml文件 ###

<?xml version="1.0" encoding="UTF-8"?>
    
    <configuration>

    	<logger name="com.common" level="DEBUG">
    		<appender-ref ref="syslog" />
    	</logger>
    </configuration>

## 2.测试文件 ##

package com.common.test;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    
    public class LogBackTest {
    
    	private static Logger LOGGER = LoggerFactory.getLogger(LogBackTest.class);
    
    	public static void main(String[] args) {
    		// TODO Auto-generated method stub
    		LOGGER.debug("我是日志");
    		LOGGER.info("我是日志");
    		LOGGER.warn("我是日志");
    		LOGGER.error("我是日志");
    	}
    }

### 日志的打印一般多用于try-catch的异常输出和接口指定信息的输出，用于观察系统的状态，方便程序员了解异常，调试处理Bug，更快得定位问题所在，进行代码的修缮。 ###

## 3.上面的测试案例输出的日志格式如下 ##
