Logback配置指定log文件日志

Logback配置指定log文件日志

前提：在项目中已配置好logback的情况下使用，此处以springboot项目环境为例。

1、定义常量

Constants.java中定义
String LOGGER_LOAD_NET_ADS_REQUEST = "load_net_ads";

2、记录日志

private static final Logger logger = LoggerFactory.getLogger(Constants.LOGGER_LOAD_NET_ADS_REQUEST);
logger.info(“记录你要记录的日志”);

3、配置logback-spring.xml

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

<configuration scan="true">
	<!--<include resource="org/springframework/boot/logging/logback/base.xml"/>-->
	<include resource="org/springframework/boot/logging/logback/defaults.xml" />
	<include resource="org/springframework/boot/logging/logback/console-appender.xml" />

	<logger name="ch.qos.logback" level="WARN"/>
	<logger name="org.apache" level="WARN"/>
	<logger name="org.apache.catalina.startup.DigesterFactory" level="OFF"/>

	<logger name="org.eclipse.jetty" level="INFO"/>

	<contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">
		<resetJUL>true</resetJUL>
	</contextListener>

    <!--source属性是定义在application.xml下，此处用于转化为logback可识别的路径-->
