Spring不同版本的AOP

1、Spring4、SpringBoot1

　　1.1 代码实现

public interface Calculator {

    int div(int a,int b);
}

@Component
public class CalculatorImpl implements Calculator{
    @Override
    public int div(int a, int b) {
        int result = a/b;
        System.out.println("计算结果为："+result);
        return result;
    }
}

@Aspect
@Component
public class CalculatorAspect {
    @Before(value = "execution(* com.jixian.springboot1.CalculatorImpl.*(..))")
    public void beforeNotify(){
        System.out.println("@Before...前置通知");
    }
    @After(value = "execution(* com.jixian.springboot1.CalculatorImpl.*(..))")
    public void afterNotify(){
        System.out.println("@After...后置通知");
    }
    @AfterReturning(value = "execution(* com.jixian.springboot1.CalculatorImpl.*(..))")
    public void afterReturningNotify(){
        System.out.println("@AfterReturning...返回通知");
    }
    @AfterThrowing(value = "execution(* com.jixian.springboot1.CalculatorImpl.*(..))")
    public void afterThrowingNotify(){
        System.out.println("@AfterThrowing...异常通知");
    }
    @Around(value = "execution(* com.jixian.springboot1.CalculatorImpl.*(..))")
    public Object aroundNotify(ProceedingJoinPoint joinPoint) throws Throwable{
        Object res = null;
        System.out.println("@Around...环绕通知之前A");
        res = joinPoint.proceed();
        System.out.println("@Around...环绕通知之后B");
        return res;
    }
}

　　1.2 测试

@SpringBootTest
@RunWith(SpringRunner.class)
public class SpringBoot1ApplicationTests {
    @Autowired
    private Calculator calculator;

    @Test
    public void contextLoads() {
        System.out.println("Spring版本："+ SpringVersion.getVersion()+"\t"+"SpringBoot版本："+ SpringBootVersion.getVersion());
        calculator.div(5,2);
    }

}
