Question

我在所有RestController注释控制器中都有一个带切入点的Aspect：

@Aspect
@Component
public class ControllerLoggingAspect {
    Logger log = LoggerFactory.getLogger(this.getClass());

    @Pointcut("within(@org.springframework.web.bind.annotation.RestController *)")
    public void controller() {
    }

    @Before("controller()")
    public void logBefore(JoinPoint joinPoint) {
        log.info("START REST CONTROLLER");
    }

    @After("controller()")
    public void logAfter(JoinPoint joinPoint) {
        log.info("END REST CONTROLLER");
    }
}

pom依赖项：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aop</artifactId>
    <version>5.0.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>1.8.12</version>
</dependency>
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjrt</artifactId>
    <version>1.7.3</version>
</dependency>

我在日志中收到以下错误： NoSuchMethodError: org.springframework.core.annotation.OrderUtils.getOrder

我可以在项目中验证我的OrderUtils类是否有getOrder方法。

如果我删除@Before和@After带注释的方法，Spring会启动时没有错误。

有没有人知道我错过了什么？

Answer 1

原来我的spring-aop和spring-core依赖项之间的版本不同。修复它们以使AOP按预期工作。

Answer 2

使AOP类成为after注释：

@Aspect
@Configuration
public class AfterAopAspect {

    private Logger logger = LoggerFactory.getLogger(this.getClass());

    @AfterReturning(value = "execution(* com.alok.*.*(..))", returning = "result")
    public void afterReturning(JoinPoint joinPoint, Object result) {
        logger.info("{} returned with value {}", joinPoint, result);
    }

    @After(value = "execution(* com.alok.*.*(..))")
    public void after(JoinPoint joinPoint) {
        logger.info("after execution of {}", joinPoint);
    }
}

启动时Spring AOP失败：NoSuchMethodError：org.springframework.core.annotation.OrderUtils.getOrder
