Spring集成logback有个链接：https://github.com/qos-ch/logback-extensions/wiki/Spring

暂时Spring还不直接支持logback，所以需要手动配置上监听器，需要`logback-ext-spring-version.jar支持，这个jar包可以到`百度网盘:http://pan.baidu.com/share/link?shareid=1639326955&uk=1594827425 下载，也可下载源代码手动打包

pom.xml文件中添加配置：

<dependency>  
              <groupId>org.slf4j</groupId>  
              <artifactId>slf4j-api</artifactId>  
              <version>1.7.5</version>  
              <type>jar</type>  
             <scope>compile</scope>  
           </dependency>  
           <dependency>  
              <groupId>ch.qos.logback</groupId>  
              <artifactId>logback-core</artifactId>  
              <version>1.0.13</version>  
              <type>jar</type>  
           </dependency>  
           <dependency>  
              <groupId>ch.qos.logback</groupId>  
              <artifactId>logback-classic</artifactId>  
              <version>1.0.13</version>  
              <type>jar</type>  
           </dependency>

resources下添加配置文件：logback.xml

<property name="LOG\_HOME" value="logs/"/>      
    <appender name="Console" class="ch.qos.logback.core.ConsoleAppender">  
        <encoder>  
            <pattern>%d\{H:mm\} %-5level \[%logger\{16\}\] %msg%n</pattern>  
        </encoder>  
    </appender>  
     
       
    <appender name="FILE"  
        class="ch.qos.logback.core.rolling.RollingFileAppender">   
        <Encoding>UTF-8</Encoding>   
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">   
            <FileNamePattern>$\{LOG\_HOME\}/myApp.%d\{yyyy-MM-dd\}.log</FileNamePattern>   
            <MaxHistory>30</MaxHistory>   
        </rollingPolicy>   
        <layout class="ch.qos.logback.classic.PatternLayout">   
            <pattern>%d\{HH:mm:ss.SSS\} \[%thread\] %-5level %logger\{50\} - %msg%n   
            </pattern>   
       </layout>   
    </appender>    
  
      
    <logger name="com.bcc" level="debug" />   
  
    <root level="info">   
        <appender-ref ref="Console" />   
        <appender-ref ref="FILE" />  
    </root>  
</configuration>

web.xml中加入：

<context-param>  
        <param-name>logbackConfigLocation</param-name>  
        <param-value>classpath:logback.xml</param-value>   
    </context-param>  
    <listener>  
        <listener-class>ch.qos.logback.ext.spring.web.LogbackConfigListener</listener-class>  
    </listener>

注意路径保存位置

类中加入：private static Logger log = LoggerFactory.getLogger(ClassName.class)

即可打log了 优先级由低到高分别为

log.trace("======trace");

log.debug("======debug");  
    log.info("======info");  
    log.warn("======warn");  
    log.error("======error");

String name = "Aub";  
    String message = "3Q";  
    String\[\] fruits = \{ "apple", "banana" \};  
      
    // logback提供的可以使用变量的打印方式，结果为"Hello,Aub!"  
    log.info("Hello,\{\}!", name);  
      
    // 可以有多个参数,结果为“Hello,Aub! 3Q!”  
    log.info("Hello,\{\}!   \{\}!", name, message);
