一文详解Java操作日志的5种方案和3大误区

// 传统日志硬编码
public class TrafficService {
    private static final Logger logger = LoggerFactory.getLogger(TrafficService.class);

    public void updateRoute(String routeId, String newStatus) {
        logger.info("Updating route {} to status {}", routeId, newStatus);
        // 业务逻辑...
        if (someError) {
            logger.error("Failed to update route {}: {}", routeId, e.getMessage());
        }
    }
}

@Aspect
@Component
public class OperationLogAspect {
    private static final Logger logger = LoggerFactory.getLogger(OperationLogAspect.class);

    @Around("@annotation(OperationLog)")
    public Object logOperation(ProceedingJoinPoint joinPoint) throws Throwable {
        String methodName = joinPoint.getSignature().getName();
        Object[] args = joinPoint.getArgs();

        logger.info("Entering method {}: {}", methodName, Arrays.toString(args));
        Object result = joinPoint.proceed();
        logger.info("Exiting method {}: Result={}", methodName, result);

        return result;
    }
}

@Component
public class AsyncLogService {
    @Async
    public void logOperation(String operation, String detail) {
        // 发送到消息队列或异步写入数据库
        logQueue.offer(new LogEntry(operation, detail));
    }
}

@Aspect
@Component
public class AsyncLogAspect {
    @Autowired
    private AsyncLogService asyncLogService;

    @AfterReturning(pointcut = "@annotation(OperationLog)", returning = "result")
    public void logAfterReturn(JoinPoint joinPoint, Object result) {
        String operation = joinPoint.getSignature().getName();
        asyncLogService.logOperation(operation, "Result: " + result);
    }
}

// SLF4J + Logback配置
public class AuditService {
    private static final Logger logger = LoggerFactory.getLogger(AuditService.class);

    public void auditOperation(String userId, String action) {
        logger.info("User {} performed action: {}", userId, action);
    }
}
