1.pom依赖
<dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.12</version> </dependency>
2.resources下logback.xml配置,也可通过application.properties进行日志配置
<?xml version="1.0" encoding="UTF-8"?> <configuration debug="false"> <!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径--> <property name="LOG_HOME" value="/datalog/logs"/> <!--<property name="LOG_HOME" value="H:\logs"/>--> <property name="LOG_NAME" value="testservice"/> <!-- Logback最简洁spring boot默认推荐使用--> <!-- 彩色日志 --> <!-- 彩色日志依赖的渲染类 --> <conversionRule conversionWord="clr" converterClass="org.springframework.boot.logging.logback.ColorConverter"/> <conversionRule conversionWord="wex" converterClass="org.springframework.boot.logging.logback.WhitespaceThrowableProxyConverter"/> <conversionRule conversionWord="wEx" converterClass="org.springframework.boot.logging.logback.ExtendedWhitespaceThrowableProxyConverter"/> <!-- 彩色日志格式 --> <property name="CONSOLE_LOG_PATTERN" value="${CONSOLE_LOG_PATTERN:-%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}"/> <property name="FILE_LOG_PATTERN" value="%-12(%d{yyyy-MM-dd HH:mm:ss.SSS}) |-%-5level [%thread] %c [%L] -| %msg%n"/> <!-- 控制台彩色日志输出 --> <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>${CONSOLE_LOG_PATTERN}</pattern> <!-- <charset>utf8</charset>--> </encoder> </appender> <!-- 按照每天生成日志文件 --> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <File>${LOG_HOME}/${LOG_NAME}.log</File><!--不指定会出现Linux无法输出文件--> <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"> <!-- rollover daily --> <FileNamePattern>${LOG_HOME}/${LOG_NAME}.log.%d{yyyy-MM-dd}.%i.log</FileNamePattern> <!-- each file should be at most 100MB, keep 60 days worth of history, but at most 20GB --> <maxFileSize>200MB</maxFileSize> <maxHistory>3</maxHistory> <totalSizeCap>20GB</totalSizeCap> </rollingPolicy> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> <pattern>${FILE_LOG_PATTERN}</pattern> </encoder> </appender> <logger name="org.apache" level="INFO"/> <logger name="httpclient" level="INFO"/> <logger name="sun.rmi" level="INFO"/> <logger name="javax.management" level="INFO"/> <logger name="org.springframework.beans" level="INFO"/> <!--<logger name="org.springframework.jdbc" level="DEBUG"/>--> <logger name="org.springframework.core" level="INFO"/> <logger name="org.springframework" level="INFO"/> <!-- 日志输出级别 --> <root level="INFO"> <appender-ref ref="CONSOLE"/> <appender-ref ref="FILE"/> </root> </configuration>
3.在需要使用日志的类上加@Slf4j 注解
log.info(“logindata:–》{}–》{}–》{}”, “111”, “222”, “333”);
