Spring mvc 환경에서 aop : logging 적용예제

Spring mvc 환경에서 aop 를 이용해

logging을 컨트롤러에서

함수실행시 request와  결과값을 log로 남겨주었다.

1. AOP를 위한 설정

# IN pom.xml

<!--        aop 위해 추가-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aop</artifactId>
            <version>4.3.25.RELEASE</version>
        </dependency>
        <!-- AspectJ -->
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjrt</artifactId>
            <version>1.8.14</version>
        </dependency>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjtools</artifactId>
            <version>1.9.9</version>
        </dependency>

aop 와 aspectj 언어를 사용하기위해 의존성을 추가한다.

# IN dispatcher-servlet.xml

<!--    aop설정을위해 추가-->
    <aop:aspectj-autoproxy/>

2. AOP 구현

# loggingAspect class 작성 : 이곳에서 aop 함수를 작성한다.

package idmcs.api.pub.rrc.provider.requestRrcQr.common;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

import javax.persistence.criteria.JoinType;
import java.util.Arrays;


@Aspect
@Component
public class LoggingAspect {
    public static final String FONT_GREEN = "\u001B[32m";
    public static final String RESET = "\u001B[0m";
    public static final String FONT_BLUE = "\u001B[34m";
    private static final Logger logger = LoggerFactory.getLogger(LoggingAspect.class);

    @Around("execution(* idmcs.api.pub.rrc.provider.requestRrcQr.controller..*(..))")
    public Object logPrint(ProceedingJoinPoint proceedingJoinPoint) throws Throwable {


        long start = System.currentTimeMillis();

        Object result = proceedingJoinPoint.proceed();
        Object[] args = proceedingJoinPoint.getArgs();
        String type = proceedingJoinPoint.getSignature().getDeclaringTypeName();
        String name = "";

        if (type.contains("Controller")) {
            name = "[Request]Controller : ";

        } else if (type.contains("Service")) {
            name = "Service : ";

        } else if (type.contains("VO")) {
            name = "Persistence : ";
        }

        long end = System.currentTimeMillis();
        logger.info(FONT_GREEN + "■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■");
        logger.info(name + type + "."+proceedingJoinPoint.getSignature().getName() + "()");
        logger.info("Argument/Parameter : " + Arrays.toString(proceedingJoinPoint.getArgs()));
        logger.info("----------------------------------------------------------------");
        logger.info(FONT_BLUE+"[Response] : {}({}) = {} ({}ms)", proceedingJoinPoint.getSignature().getDeclaringTypeName(),
                proceedingJoinPoint.getSignature().getName(), result,(end-start));
        logger.info("■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■" + RESET);

        return result;
    }

}

 

지금은 controller 에서만 잡아놓고 있지만 service및 vo에서 잡을수도 있도록하려고 name설정을 여러개를 넣어둠.
