AOP集成log4j日志

1、配置文件

@Aspect
@Component
public class WebLogAspect {

    private static final Logger logger = LoggerFactory.getLogger(WebLogAspect.class);

    @Pointcut("execution(public * com.itmayiedu.controller.*.*(..))")
    public void webLog() {
    }

    @Before("webLog()")
    public void doBefore(JoinPoint joinPoint) throws Throwable {
        // 接收到请求，记录请求内容
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        // 记录下请求内容
        logger.info("URL : " + request.getRequestURL().toString());
        logger.info("HTTP_METHOD : " + request.getMethod());
        logger.info("IP : " + request.getRemoteAddr());
        Enumeration<String> enu = request.getParameterNames();
        while (enu.hasMoreElements()) {
            String name = (String) enu.nextElement();
            logger.info("name:{},value:{}", name, request.getParameter(name));
        }
    }

    @AfterReturning(returning = "ret", pointcut = "webLog()")
    public void doAfterReturning(Object ret) throws Throwable {
        // 处理完请求，返回内容
        logger.info("RESPONSE : " + ret);
    }
}

2、POM.xml引入依赖

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