Spring 之Aop实现日志记录

Aop实现见代码，简单demo实现

package com.idcos.automate.config;

import com.idcos.automate.dal.auto.dao.dcos.DcosLogDAO;
import com.idcos.automate.dal.auto.dataobject.dcos.DcosLogDO;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
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.math.BigDecimal;
import java.util.Arrays;

@Aspect//切面注解
@Component//@Component泛指组件，当组件不好归类的时候，我们可以使用这个注解进行标注。
public class LoggerConfig {

    @Autowired
    private DcosLogDAO dcosLogDAO;

    private final org.slf4j.Logger log = LoggerFactory.getLogger(this.getClass());


    //定义切点，监听所有的web下的controller
    @Pointcut("execution(public * com.idcos.automate.web..*.*(..))")
    public void webLog() {
    }

    //抛出切点连接中的异常信息
    @AfterThrowing(pointcut = "webLog()", throwing = "e")
    public void logAfterThrowing(JoinPoint joinPoint, Throwable e) {
        log.error("Exception in {}.{}.() cause = {}", joinPoint.getSignature().getDeclaringType(), joinPoint.getSignature().getName(), e.getCause() != null ? e.getCause() : null);
    }

    /**

    @Around("webLog()")
    public void logWebAccessInfo(ProceedingJoinPoint proceedingJoinPoint) throws Throwable {

        long start = System.currentTimeMillis();
        //JoinPoint、ProceedingJoinPoint提供访问当前被通知方法的目标对象、代理对象、方法参数等数据，其中ProceedingJoinPoint提供访问当前被通知方法的目标对象
        // 在环绕Around时使用：
        proceedingJoinPoint.proceed();
        long end = System.currentTimeMillis();//测试方法执行后的时间是多少
        float time =  BigDecimal.valueOf(end-start).divide(BigDecimal.valueOf(1000)).setScale(3, BigDecimal.ROUND_HALF_UP).floatValue();

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

        // 记录下请求内容
        log.info("URL : " + request.getRequestURL().toString());//请求的url
        log.info("HTTP_METHOD : " + request.getMethod());//请求的方法
        log.info("IP : " + request.getRemoteAddr());//请求方的ip
        log.info("CLASS_METHOD : " + proceedingJoinPoint.getSignature().getDeclaringTypeName() + "." + proceedingJoinPoint.getSignature().getName());
        log.info("ARGS : " + Arrays.toString(proceedingJoinPoint.getArgs()));//请求的参数

        DcosLogDO dcosLogDO = new DcosLogDO();

        dcosLogDO.setClassName(request.getClass().getName());
        dcosLogDO.setMethodName(request.getMethod());
        dcosLogDO.setUrl(request.getRemoteAddr()+request.getRequestURL());
        dcosLogDO.setTime(Float.toString(time));
        dcosLogDAO.saveAndFlush(dcosLogDO);
    }
