Spring - 如何使用 aspectJ 缓存自调用？

Question

感谢您点击我的问题。我想在自调用中调用缓存方法，所以需要使用AspectJ。(缓存的配置没问题)

1. 添加 AspectJ 依赖项

implementation 'org.springframework.boot:spring-boot-starter-aop'

1. 将 @EnableCaching(mode = AdviceMode.ASPECTJ) 添加到我的 application.java

@EnableJpaAuditing
@EnableCaching(mode = AdviceMode.ASPECTJ) // <-- here 
@SpringBootApplication
public class DoctorAnswerApplication {

    public static void main(String[] args) {
        SpringApplication.run(DoctorAnswerApplication.class, args);
    }

}

1. 我的服务.java

@Service
public class PredictionService {

    @Cacheable(value = "findCompletedRecordCache")
    public HealthCheckupRecord getRecordComplete(Long memberId, String checkupDate) {
        Optional<HealthCheckupRecord> recordCheckupData;
        recordCheckupData = healthCheckupRecordRepository.findByMemberIdAndCheckupDateAndStep(memberId, checkupDate, RecordStep.COMPLETE);

        return recordCheckupData.orElseThrow(NoSuchElementException::new);
    }
}

4. 我的测试代码

    @Test
    public void getRecordCompleteCacheCreate() {
        // given
        Long memberId = (long)this.testUserId;
        List<HealthCheckupRecord> recordDesc = healthCheckupRecordRepository.findByMemberIdAndStepOrderByCheckupDateDesc(testUserId, RecordStep.COMPLETE);
        String checkupDate = recordDesc.get(0).getCheckupDate();
        String checkupDate2 = recordDesc.get(1).getCheckupDate();

        // when
        HealthCheckupRecord first = predictionService.getRecordComplete(memberId,checkupDate);
        HealthCheckupRecord second = predictionService.getRecordComplete(memberId,checkupDate);
        HealthCheckupRecord third = predictionService.getRecordComplete(memberId,checkupDate2);

        // then
        assertThat(first).isEqualTo(second);
        assertThat(first).isNotEqualTo(third);
    }

我没有...？我没有开设任何与 aspectJ 相关的类(class)。我认为 @EnableCaching(mode = AdviceMode.ASPECTJ) 使 @Cacheable 由 AspectJ 代替 Spring AOP(proxy) 工作。

Answer 1

你读过 Javadoc for EnableCaching 了吗？ ?

Note that if the mode() is set to AdviceMode.ASPECTJ, then the value of the proxyTargetClass() attribute will be ignored. Note also that in this case the spring-aspects module JAR must be present on the classpath, with compile-time weaving or load-time weaving applying the aspect to the affected classes. There is no proxy involved in such a scenario; local calls will be intercepted as well.

所以请检查你是否

1. 在类路径上有 spring-aspects 和
2. 使用参数 java -javaagent:/path/to/aspectjweaver.jar 启动您的应用程序。

#2 有一个替代方案，但使用 Java 代理是最简单的。我不是 Spring 用户，所以我不是 Spring 配置方面的专家，但即使像我这样的 Spring 菜鸟也成功使用了 Java 代理，所以请先试一试。
