springboot-aop

springboot-aop

1，添加 pom 依賴

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

2，編寫 aop 切面類

package com.test.springboot.aop;

import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;
import java.util.Enumeration;

/**
 * 
 */
@Aspect
@Component
@Slf4j
public class WebLogAspect {

    @Pointcut("execution(public * com.test..*.*(..))")
    public void webLog(){

    }

    @Before("webLog()")
    public void doBefore(JoinPoint joinPoint) throws Throwable {
        // 接收到請求，記錄請求內容
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        // 記錄下請求內容
        log.info("URL : " + request.getRequestURL().toString());
        log.info("HTTP_METHOD : " + request.getMethod());
        log.info("IP : " + request.getRemoteAddr());
        Enumeration<String> enu = request.getParameterNames();
        while (enu.hasMoreElements()) {
            String name = (String) enu.nextElement();
            log.info("name:{},value:{}", name, request.getParameter(name));
        }
    }
    
    @AfterReturning(returning = "ret", pointcut = "webLog()")
    public void doAfterReturning(Object ret) throws Throwable {
        // 處理完請求，返回內容
        log.info("RESPONSE : " + ret);
    }
}
