springboot aop记录日志

一，添加依赖

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-aop</artifactId>

</dependency>

二，编写切面类

/**

@Aspect
@Component
@Order(-5)
public class WebLogAspect {
    private  final Logger log = LoggerFactory.getLogger(WebLogAspect.class);
    private static ThreadLocal<Long> time = new ThreadLocal<Long>(){
        protected Long initialValue() {
            long beginTime = System.currentTimeMillis();
            return beginTime;
        }
    };//直接注入会有空指针问题
    private static final ThreadLocal<InvokeLog> invokelog = new ThreadLocal<InvokeLog>(){
        protected InvokeLog initialValue() {
            return new InvokeLog();
        }
    };
    @Autowired
    InvokeLogMapper invokeLogMapper;

    public WebLogAspect() {
    }

    /**

     * ~ 第二个 * 任意包名

    @Pointcut("@annotation(com.kuainiu.beidou.service.base.components.InvokeLog)")
    public void invokeLog(){
        invokelog.set(new InvokeLog());
    }
    @Before(value = "invokeLog()")
    public void doBefore(JoinPoint joinPoint) throws Throwable {
        time.set(System.currentTimeMillis());

        HttpServletRequest request = attributes.getRequest();

        invokeLog.setIp(request.getRemoteAddr());
        invokeLog.setClassMethod(joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
        invokeLog.setArgs(Arrays.toString(joinPoint.getArgs()));
    }
    @AfterReturning(returning = "ret", pointcut = "invokeLog()")
    public void doAfterReturning(Object ret) throws Throwable {
        // 处理完请求，返回内容
        log.info("RESPONSE : " + ret);
        InvokeLog invokeLog = invokelog.get();
        invokeLog.setResponse(ret.toString());
        invokeLog.setTime((System.currentTimeMillis()-time.get()));
        invokeLogMapper.insert(invokeLog);
    }
    @After(value = "invokeLog()")
    public void after(){
    }
}

注意：遇到aop一直不生效的问题，是因为切面类没有被spring启动类管理，解决：扫面切面类所在包
