Spring 带有自定义注释的 AOP 不工作

Question

我查看了每个 example on stack exchange 和 spring 的示例网站，一切似乎都应该有效。我一定是遗漏了一些简单的东西

我有一个自定义注释，理想情况下我想将其应用于 class 的所有方法（如果 class 被注释）或任何被注释的方法。这是方面、测试和代码：

注释

import java.lang.annotation.Retention;
import java.lang.annotation.Target;

import static java.lang.annotation.ElementType.METHOD;
import static java.lang.annotation.RetentionPolicy.RUNTIME;

@Target({METHOD})
@Retention(RUNTIME)
public @interface Monitor {
    String value() default "Monitor";
}

看点

@Aspect
@Component
public class LatencyAspect {

    @Autowired
    private Logger logger;

    @Around("@annotation(Monitor)")
    public Object logAround(ProceedingJoinPoint joinPoint) throws Throwable {
        Object retVal = joinPoint.proceed();

        logger.info("logged");

        return retVal;
    }
}

测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class,classes = {LatencyConfig.class, LatencyTest.ContextConfiguration.class})
@ComponentScan
public class LatencyTest {
    final static Logger log = mock(Logger.class);

    @Autowired
    private SomeClass someClass;


    @Test
    public void testExample() throws Exception {
        someClass.doSomething("foo");
        verify(log).info("logged");

    }

    @EnableAspectJAutoProxy(proxyTargetClass = true)
    @Configuration
    static class ContextConfiguration {


        @Bean
        public SomeClass properties() {
            return new SomeClass();
        }

        @Bean
        public Logger log() {
            return log;
        }
    }


    public static class SomeClass {

        @Monitor
        @Transient
        public String doSomething(String whatever) {
            return "done";
        }
    }
}

结果

Wanted but not invoked:
logger.info("logged");
-> at org.bongiorno.latency.LatencyTest.testExample(LatencyTest.java:74)
Actually, there were zero interactions with this mock.

Spring 没有从 JUnit 测试 class 中获取 @ComponentScan 注释。将注释移动到您的 LatencyConfig class 或测试本地 LatencyTest.ContextConfiguration 内部配置 class.
