springboot使用aspectJ

添加springboot-aop的starter

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-aop</artifactId>
</dependency>
编写切面代码（先执行环绕方法->方法前->方法后->方法返回后，开启环绕方法时，异常方法无效）

@Aspect
@Component
public class AspectService {
    //coder.rdf.mybatis.study.service包下的所有类的所有方法
    @Before(value="execution(* coder.rdf.mybatis.study.service.*.*(..))")
    public void before(JoinPoint joinPoint) throws Throwable {
        Object[] args = joinPoint.getArgs();
        String name = joinPoint.getSignature().getName();
        System.out.println("方法前****切面方法**"+name+"***"+ Arrays.toString(args));
    }

    @After(value="execution(* coder.rdf.mybatis.study.service.*.*(..))")
    public void after(JoinPoint joinPoint){
        Object[] args = joinPoint.getArgs();
        String name = joinPoint.getSignature().getName();
        System.out.println("方法后****切面方法**"+name+"***"+ Arrays.toString(args));
    }
    @AfterReturning(value="execution(* coder.rdf.mybatis.study.service.*.*(..))" ,returning = "result")
    public void afterRunning(JoinPoint joinPoint,Object result){
        Object[] args = joinPoint.getArgs();
        String name = joinPoint.getSignature().getName();
        System.out.println("方法反回后****切面方法**"+name+"***"+ Arrays.toString(args)+"***"+result);
    }
    @Around(value="execution(* coder.rdf.mybatis.study.service.*.*(..))")
    public Object rounding(ProceedingJoinPoint joinPoint) throws Throwable {
        long start = Time.now();
        System.out.println("环绕方法开始****");
        Object proceed = null;
        try {
            Object[] args = joinPoint.getArgs();
            proceed = joinPoint.proceed(args);
        } catch (Throwable throwable) {
            throw new Throwable("方法调用失败");
        }
        System.out.println("环绕方法结束****");
        long end = Time.now();
        System.out.println("****方法执行时间**"+(start-end));
        return proceed;
    }

    @AfterThrowing(value = "execution (* coder.rdf.mybatis.study.service.*.*(..))", throwing = "e")
    public void throwException(JoinPoint joinPoint, Exception e) {
        String methodName = joinPoint.getSignature().getName();
        System.out.println("异常方法调用:" + methodName + " 异常信息" + e);
    }
}
