Aspectj + 어노테이션으로 로그남기기

1. pom.xml

		<!-- AspectJ --> 
		<dependency> 
			<groupId>org.aspectj</groupId> 
			<artifactId>aspectjrt</artifactId> 
			<version>${org.aspectj-version}</version> 
		</dependency> 
		
		<dependency> 
			<groupId>org.aspectj</groupId> 
			<artifactId>aspectjweaver</artifactId> 
			<version>${org.aspectj-version}</version> 
		</dependency> 
		
		<dependency> 
			<groupId>org.aspectj</groupId> 
			<artifactId>aspectjtools</artifactId> 
			<version>${org.aspectj-version}</version> 
		</dependency>

 

2. servelt-context.xml  aspectJ설정

	<!-- @Aspect어노테이션이 있는 클래스를 자동으로 찾아서 설정해줌 -->
	<aop:aspectj-autoproxy/> 

 

3. Annotation Interface 설정

package secretary.common.annotation;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface LogExecutionTime {

}

 

4. Aspectj으로   Annotation 구현

package secretary.common.aspect;

import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.springframework.stereotype.Component;
import org.springframework.util.StopWatch;

@Component
@Aspect
public class LogAspect {
	
	Logger log = LogManager.getLogger(this.getClass());
	
	@Around("@annotation(secretary.common.annotation.LogExecutionTime)")
	public Object logExecutionTime(ProceedingJoinPoint joinPoint) throws Throwable{
		StopWatch stopWatch = new StopWatch();
		stopWatch.start();
		log.debug("시작================>");
		Object proceed = joinPoint.proceed();
		stopWatch.stop();
		log.debug("끝================>"+stopWatch.prettyPrint());
		System.out.println("annotation======>");
		
		return proceed;
	}
}

5. Controller에 Annotation 설정

package secretary.common.controller;

import java.util.Locale;

import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import secretary.common.annotation.LogExecutionTime;
import secretary.common.service.TestService;

@Controller
public class MainController {

	private Logger log = LogManager.getLogger(this.getClass());

	@Autowired
	private TestService testService;

	@RequestMapping(value = "/main.do")
	@LogExecutionTime
	public String main(Locale locale, Model model) {
		String result = testService.selectNow();
		log.info("=======>main: " + result);

		return "common/main";
	}
}
