(一)log4j2 maven配置
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <!-- 切换log4j2日志读取 --> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency>
<!-- 配置 log4j2 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-log4j2</artifactId> </dependency> <!-- 加上这个才能辨认到log4j2.yml文件 --> <dependency> <groupId>com.fasterxml.jackson.dataformat</groupId> <artifactId>jackson-dataformat-yaml</artifactId> </dependency>
在resources 文件夹下创建log4j2.yml 文件
Configuration: status: warn Properties: # 定义全局变量 Property: # 缺省配置(用于开发环境)。其他环境需要在VM参数中指定,如下: #测试:-Dlog.level.console=warn -Dlog.level.xjj=trace #生产:-Dlog.level.console=warn -Dlog.level.xjj=info - name: log.level.console value: trace - name: log.level.xjj value: trace - name: log.path value: D:/Logs/log - name: project.name value: my-spring-boot Appenders: Console: #输出到控制台 name: CONSOLE target: SYSTEM_OUT ThresholdFilter: level: ${sys:log.level.console} # “sys:”表示:如果VM参数中没指定这个变量值,则使用本文件中定义的缺省全局变量值 onMatch: ACCEPT onMismatch: DENY PatternLayout: pattern: "%d{yyyy-MM-dd HH:mm:ss,SSS}:%4p %t (%F:%L) - %m %X{REQUESTID} %n" RollingFile: # 输出到文件,超过128MB归档 - name: ROLLING_FILE ignoreExceptions: false fileName: ${log.path}/${project.name}.log filePattern: "${log.path}/$${date:yyyy-MM}/${project.name}-%d{yyyy-MM-dd}-%i.log.gz" PatternLayout: pattern: "%d{yyyy-MM-dd HH:mm:ss,SSS}:%4p %t (%F:%L) - %m %X{REQUESTID} %n" Policies: SizeBasedTriggeringPolicy: size: "128 MB" DefaultRolloverStrategy: max: 1000 Loggers: Root: level: info AppenderRef: - ref: CONSOLE - ref: ROLLING_FILE Logger: # 为com.xjj包配置特殊的Log级别,方便调试 - name: com.xjj additivity: false level: ${sys:log.level.xjj} AppenderRef: - ref: CONSOLE - ref: ROLLING_FILE
其中 %X{REQUESTID} 为MDC设定的请求标识,每个请求都会有,用于跟踪日志。
(二)MDC和AOP 环绕增强、自定义注解
创建日志类
public class tools_log { public static Logger getLogger(Class class_) { Logger logger = LoggerFactory.getLogger(class_); return logger; } }//end
AOP、MDC
@Aspect @Component @Slf4j public class LogAspect { @Pointcut("execution(public * 包路径..*.*(..))") public void LogHelp() { } @Pointcut("@annotation(自定义注解路径)") public void noAnnotation() { } final Logger logger = tools_log.getLogger(this.getClass()); @Around("LogHelp()&&!noAnnotation()") public Object arround(ProceedingJoinPoint joinPoint) { MDC.put("REQUESTID", UUID.randomUUID().toString()); logger.info("方法环绕start....."); // 接收到请求,记录请求内容 ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes(); HttpServletRequest request = attributes.getRequest(); // 记录下请求内容 logger.info("URL : " + request.getRequestURL().toString()); logger.info("HTTP_METHOD : " + request.getMethod()); logger.info("IP : " + request.getRemoteAddr()); logger.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName()); logger.info("ARGS : " + JSON.toJSONString(joinPoint.getArgs())); try { Object o = joinPoint.proceed(); logger.info("方法环绕proceed,结果是 :" + o); return o; } catch (Throwable e) { logger.error(e.toString()); return null; } finally { MDC.clear(); } } }//end
.. 表示匹配多个参数
* 表示匹配一个参数
.* 表示匹配多个类
自定义注解
@Target({ElementType.METHOD, ElementType.TYPE}) @Retention(RetentionPolicy.RUNTIME) public @interface noAroundAnno { }//end
定义在方法上
