SpringBoot基于自定义注解实现切面编程

1、相关依赖包

 
    
      org.springframework.boot
      spring-boot-starter-aop
    

    
      org.aspectj
      aspectjrt
      1.8.6
    

2、定义切面类

package com.bz.aspect;

import com.bz.service.SysLogOperationService;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;


@Aspect
@Component
public class LogOperationAspect {
  @Autowired(required = false)
  private SysLogOperationService sysLogOperationService;

  @Pointcut("@annotation(com.bz.aspect.BzLogOperation)")
  public void logPointCut() {
    System.out.println("lllll");
  }

  
  @Before("logPointCut()")
  public void begin() {
    System.out.println("前置通知：方法执行前调用");
  }

  
  @AfterReturning("logPointCut()")
  public void afterReturning() {
    System.out.println("后置通知： 方法执行后调用，若方法出现异常，不执行");
  }

  
  @After("logPointCut()")
  public void after() {
    System.out.println("最终通知：无论无何都会调用，类似于：try/catch中的finally");
  }

  
  @AfterThrowing("logPointCut()")
  public void afterThrowing() {
    System.out.println("异常通知：方法抛出异常时执行");
  }

  
  @Around("logPointCut()")
  public void around(ProceedingJoinPoint point) throws Throwable {
    // 获取切点方法的名称
    String methodName = point.getSignature().getName();
    // 获取方法传入参数
    Object[] params = point.getArgs();
    //转成字符串
    List
