Spring Boot 進階之Web進階 學習 - 使用AOP處理請求

AOP 面向切面編程

1.添加aop依賴

pom.xml中添加

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

2.建立切面文件 HttpAspect.java

@Aspect    //切面 註解
@Component
public class HttpAspect {

    private final static Logger logger = LoggerFactory.getLogger(HttpAspect.class); //日誌記錄

    @Pointcut("execution(public * com.example.girl.controller.GirlController.*(..))")  
    private void log(){
    }


    @Before("log()")
    public void doBefor(JoinPoint joinPoint){

        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes();
        HttpServletRequest request = attributes.getRequest();

        logger.info("url={}",request.getRequestURL());
        logger.info("method={}",request.getMethod());
        logger.info("ip={}",request.getRemoteAddr());
        logger.info("class_method={}",joinPoint.getSignature().getDeclaringTypeName()+"."+joinPoint.getSignature().getName());
        logger.info("args={}",joinPoint.getArgs());
    }

    @After("log()")
    public void doAfter(){
        logger.info("doAfter.......");
    }

    @AfterReturning(returning = "object",pointcut = "log()")    public void doAfterReturning(Object object){        logger.info("response={}",object.toString());    }}
