springboot Aop 統一處理Web請求日志

1.增加依賴

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>

2.編寫切面類

@Aspect
@Component
public class WebLogAspect {}

注解 @Aspect 表明這是個切面類

3.定義切點

@Pointcut("execution(* com.example.manage.controller.*.*(..))")
    public void pointLog(){}

表明切入點為 com.example.manage.controller 路徑下所有類 所有方法

4.定義切入的內容

@Before("pointLog()")
    public void dobefore(JoinPoint joinPoint){
        // 接收到請求，記錄請求內容
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        
        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 : " + Arrays.toString(joinPoint.getArgs()));
    }

執行方法前先打印出請求信息

@AfterReturning(returning = "res", pointcut = "pointLog()")
    public void doAfterReturning(Object res) throws Throwable {
        // 處理完請求，返回內容
        logger.info("RESPONSE : " + res.toString());
    }

執行完畢后，打印返回內容

完畢！
