pom.xml里面需要引用相应的jar包

  <dependency>            <groupId>org.slf4j</groupId>            <artifactId>slf4j-api</artifactId>            <version>1.7.10</version>        </dependency>        <dependency>            <groupId>ch.qos.logback</groupId>            <artifactId>logback-core</artifactId>            <version>1.1.1</version>            <type>jar</type>        </dependency>        <dependency>            <groupId>ch.qos.logback</groupId>            <artifactId>logback-classic</artifactId>            <version>1.1.1</version>            <type>jar</type>        </dependency>

logback会自动去寻找logback-test.xml和logback.xml配置文件，如果都不存在，使用默认配置。

logback.xml

<?xml version="1.0" encoding="UTF-8"?><configuration>       <property resource="config.properties"/>       <appender name="console" class="ch.qos.logback.core.ConsoleAppender">              <encoder>                     <pattern>[%-5level][%date]--%msg--[%M][%F{16},%L]%n</pattern>              </encoder>       </appender>       <appender name="rollingFile" class="ch.qos.logback.core.rolling.RollingFileAppender">              <file>${log.path}lf.log</file>              <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">                     <fileNamePattern>${log.path}lf.%d{yyyy-MM-dd}.log</fileNamePattern>              </rollingPolicy>              <encoder>                     <pattern>[%-5level][%date]--%msg--[%M][%F{16},%L]%n</pattern>                     <charset>UTF-8</charset>              </encoder>       </appender>       <!-- project default level -->       <logger name="lf" level="${log.level}" />       <root level="INFO">              <appender-ref ref="console" />              <appender-ref ref="rollingFile" />       </root></configuration>

config.properties相应参数设置

#loglog.level=DEBUGlog.path=/home/logs/

测试

在UserServiceImpl中测试

@Servicepublic class UserServiceImpl implements UserService{    private final Logger LOG = LoggerFactory.getLogger(this.getClass());    @Autowired    UserDao userDao;    @Override    public Page<User> selectUserByCon(Map<String, Object> paramMap) {        Page<User> list = null;        try{            list=userDao.selectUserByCon(paramMap);        }catch (DataAccessException e){        }        LOG.info("selectUserByCon error.");        return list;    }}

执行结果
