/**

 **/
@Service
public class TestAopImpl {

    public String testAOPOrder(String abc) {
        System.out.println("===============【testAOPOrder方法】==============="+abc);
        return "hello world";
    }
}

执行

正常执行的结果：

===============进入Around===============
===============@Before===============
===============【testAOPOrder方法】===============haha
===============@AfterReturning===============
@AfterReturning-->返回值:hello world
===============@After===============
===============离开Around===============

当方法中存在报错时的结果：

===============进入Around===============
===============@Before===============
===============@AfterThrowing===============
@AfterThrowing-->未处理的报错信息：/ by zero
===============@After===============
===============Around抛出报错信息===============
java.lang.ArithmeticException: / by zero
