springboot实现基于aop的切面日志

本文实例为大家分享了springboot实现基于aop的切面日志的具体代码，供大家参考，具体内容如下

通过aop的切面方式实现日志

通切面拦截所有指定包下的所有方法

@Aspect
@Component
@EnableAspectJAutoProxy
public class LogAspect1{
    Logger logger = LoggerFactory.getLogger(LogAspect.class);

    
/**
 * 拦截切点
 */

    @Pointcut("execution(*xx.xx.controller.*.*(..))")
    private void logPointCut() {
        logger.info("进入注解拦截");

    }

    //前置通知，在方法之前通知
    @Before(value = "logPointCut()")
    public void before(JoinPoint jp) {
        logger.info("方法调用前：" + "类名:" + jp.getTarget().getClass().getName() + "方法名 :" + jp.getSignature().getName());
    }

    //后置通知
    @After(value = "logPointCut()")
    public void doAfter(JoinPoint jp) {
        logger.info("方法调用结束：" + "类名:" + jp.getTarget().getClass().getName() + "方法名 :" + jp.getSignature().getName());
    }

    //环绕通知
    @Around("logPointCut()")
    public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
        logger.info("方法开始调用》》》》》》");

        Object retVal = pjp.proceed();
        logger.info("方法调用结束》》》》》》");
        return retVal;
    }

    //返回通知
    @AfterReturning(pointcut = "logPointCut()")
    public void doAfterReturning(JoinPoint jp) {
        logger.info("写入日志");

    }

    //异常通知
    @AfterThrowing(pointcut = "logPointCut()", throwing = "ex")
    public void doAfterThrowing(JoinPoint jp, Throwable ex) {
        logger.info("方法异常，异常信息：" + ex.getMessage());
    }
}

拦截自定义注解

定义一个日志注解，在所有要需要记录的方法上加盖注解即可被后续的aop拦截处理

代码如下

@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Log {

    /**
     * 日志主题
     */
    public String title() default "";

    /**
     * 操作具体业务
     */
    public String business() default "";

    /**
     * 是否保留请求参数
     */
    public boolean isSaveRequestData() default false;
    /**
    * 日志的类别，主要用于日志的分开记录和查询
    **/
LogType logType() default LogType.LOGIN;
}

拦截切面的实现

@Aspect
@Component
@EnableAspectJAutoProxy
public class LogAspect {
    Logger logger = LoggerFactory.getLogger(LogAspect.class);
    @Autowired
    private ServiceDemo serviceDemo;

    /**
     * 拦截切点
     */

    @Pointcut("@annotation(moling.evolution.demo.aop.annotation.Log)")
    private void logPointCut() {
      

    }

    //前置通知，在方法之前通知
    @Before(value = "logPointCut()")
    public void before(JoinPoint jp) {
        logger.info("方法调用前：" + "类名:" + jp.getTarget().getClass().getName() + "方法名 :" + jp.getSignature().getName());
    }

    //后置通知
    @After(value = "logPointCut()")
    public void doAfter(JoinPoint jp) {
        logger.info("方法参数：{}", jp.getArgs());
        logger.info("  {} || {}", jp.getStaticPart().getId(), jp.getStaticPart().getSourceLocation());
        jp.getStaticPart().getId();

        logger.info("方法调用结束：" + "类名:" + jp.getTarget().getClass().getName() + "方法名 :" + jp.getSignature().getName());
    }

    //环绕通知
    @Around("logPointCut()")
    public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
        logger.info("方法开始调用》》》》》》");

        Object retVal = pjp.proceed();
        logger.info("方法调用结束》》》》》》");
        return retVal;
    }

    //返回通知
    @AfterReturning(pointcut = "logPointCut()", returning = "object")
    public void doAfterReturning(JoinPoint jp, Object object) {
        System.out.println("返回通知");
        Log log = null;
        try {
            log = getAnnotationLog(jp);
        } catch (Exception e) {
            e.printStackTrace();

        }
        System.out.println(object);
        System.out.println(log);
        if (log != null) {
            logger.info(log.title());
            logger.info(log.business());
            logger.info(log.user());
            logger.info(log.isSaveRequestData() + "");
        } else {
            logger.error("获取注解信息失败");
        }
        serviceDemo.demo();

    }

    //异常通知
    @AfterThrowing(pointcut = "logPointCut()", throwing = "ex")
    public void doAfterThrowing(JoinPoint jp, Throwable ex) {
        logger.info("方法异常，异常信息：" + ex.getMessage());
        serviceDemo.error();
    }

    /**
     * 是否存在注解，如果存在就获取
     */

    private Log getAnnotationLog(JoinPoint joinPoint) throws Exception {
        Signature signature = joinPoint.getSignature();
        MethodSignature methodSignature = (MethodSignature) signature;
        Method method = methodSignature.getMethod();
        if (method != null) {
            return method.getAnnotation(Log.class);
        }
        return null;
    }
}

基于事件通知实现日志的记录

• 拦截切面的实现

@Aspect
@Component
@EnableAspectJAutoProxy
public class LogAspectContext {

    Logger logger = LoggerFactory.getLogger(LogAspectContext.class);
    @Autowired
    private ApplicationContext applicationContext;

    /**
     * 拦截切点
     */
    @Pointcut("@annotation(moling.evolution.demo.aop.annotation.Log)")
    private void logPointCut() {
        logger.info("进入注解拦截");

    }

    //返回通知
    @AfterReturning(pointcut = "logPointCut()", returning = "object")
    public void doAfterReturning(JoinPoint jp, Object object) throws Exception {
        applicationContext.publishEvent(new LogSuccessEvent(jp, null));

    }

    //异常通知
    @AfterThrowing(pointcut = "logPointCut()", throwing = "ex")
    public void doAfterThrowing(JoinPoint jp, Throwable ex) {
        logger.info("方法异常，异常信息：" + ex.getMessage());
        applicationContext.publishEvent(new LogSuccessEvent(jp, ex));
    }

    /**
     * 是否存在注解，如果存在就获取
     */
    private Log getAnnotationLog(JoinPoint joinPoint) throws Exception {
        Signature signature = joinPoint.getSignature();
        MethodSignature methodSignature = (MethodSignature) signature;
        Method method = methodSignature.getMethod();
        if (method != null) {
            return method.getAnnotation(Log.class);
        }
        return null;
    }
}

@Slf4j
@Service
public class ApplicationListener implements org.springframework.context.ApplicationListener<LogSuccessEvent> {

    @Autowired
    private ServiceDemo demo;

    @Override
    public void onApplicationEvent(LogSuccessEvent event) {
        JoinPoint joinPoint = event.getJp();
        Throwable ex = event.getThrowable();
        if (ex == null) {
            demo.demo();
        } else {
            demo.error();
        }
    }

}

@Slf4j
public class LogSuccessEvent extends ApplicationEvent {
    /**
     * Create a new ApplicationEvent.
     *
     * @param source the component that published the event (never {@code null})
     */
    private JoinPoint jp;

    private Throwable throwable;

    public LogSuccessEvent(Object source, Throwable throwable) {
        super(source);
        this.throwable = throwable;
        this.jp = (JoinPoint) source;
//        Log logger = (Log) source;
//        log.info(logger.title());
//        log.info(logger.business());
//        log.info(logger.user());
//       log.info(logger.isSaveRequestData() + "");

    }

    public JoinPoint getJp() {
        return jp;
    }

    public Throwable getThrowable() {
        return throwable;
    }
}
