自定义注解实现logback配置按名称打印日志

首先是目录结构

logback-spring.xml


<configuration scan="true" scanPeriod="10 seconds" debug="false">

<include resource="logback/logback-base.xml"/>

<springProfile name="dev">

<include resource="logback/logback-dev.xml"/>
springProfile>

<springProfile name="prod">

<include resource="logback/logback-prod.xml"/>
springProfile>
configuration>


logback-base.xml

<included>

<springProperty name="LOGGER_FILE_MAX_SIZE" scope="context" source="logback.filesize" defaultValue="5MB"/>

<springProperty name="LOGGER_FILE_MAX_DAY" scope="context" source="logback.filemaxday" defaultValue="2"/>

<property name="LOGGER_FILE_PATH" value="logs"/>

<property name="CHARSET" value="utf-8"/>

最后是注解的实现，技术是logback的Mdc,只要任务在同一个线程内就可以实现日志区分

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface MdcLogger {
/**
* logger MDC对应的value值
* @return
*/
String value();
}


Aop的实现

@Aspect
@Component
public class MdcLoggerAspect {
private static Logger logger = LoggerFactory.getLogger(MdcLoggerAspect.class);
/**
* 切入点
*/
@Pointcut("@annotation(com.lz.bigdata.synchronizer.biz.dy.domain.annotation.MdcLogger)")
public void mdcLoggerCutPoint() {
logger.info("MDC切入点");
}
@Before("mdcLoggerCutPoint()")
public void mdcLoggerBefore(JoinPoint joinPoint) {
MdcLogger mdcLoggerAnnotation = ((MethodSignature) joinPoint.getSignature()).getMethod().getDeclaredAnnotation(MdcLogger.class);
String value = mdcLoggerAnnotation.value();
// String methodName = joinPoint.getTarget().getClass().getSimpleName() + "." + joinPoint.getSignature().getName();
MDC.put(配置文件定义的名称(此文章是jobName), value);
}
@After("mdcLoggerCutPoint()")
public void mdcLoggerAfter() {
MDC.clear();
}
}
