一, Maven依赖包 pom.xml

 1         <dependency>
 2             <groupId>org.slf4jgroupId>
 3             <artifactId>slf4j-apiartifactId>
 4             <version>1.6.0version>
 5             <type>jartype>
 6             <scope>compilescope>
 7         dependency>
 8         <dependency>
 9             <groupId>ch.qos.logbackgroupId>
10             <artifactId>logback-coreartifactId>
11             <version>0.9.28version>
12             <type>jartype>
13         dependency>
14         <dependency>
15             <groupId>ch.qos.logbackgroupId>
16             <artifactId>logback-classicartifactId>
17             <version>0.9.28version>
18             <type>jartype>
19         dependency>



二, 代码使用

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/** logger */
private static Logger logger = LoggerFactory.getLogger(ExampleClass.class);

logger.debug("output logs");



三, 日志配置文件
配置多个logger
比如
第一个记载日志,
第二个输出告警
logback.xml

 1 xml version="1.0"?>
 2 <configuration>
 3     
 4     <property file="src\main\resources\app.properties" />
 5     <appender name="FILE"  class="ch.qos.logback.core.rolling.RollingFileAppender">
