Spring 使用Aspect时无此项定义异常

使用的弹簧启动版本：1.2.3

我们正在基于以下属性创建CacheManager：

@Bean
public CacheManager cacheManager() throws IOException {
    String cacheImpl = env.getProperty(CacheSupport.CACHE_PROPERTY, String.class, "");
    if (CacheSupport.AEROSPIKE.equalsIgnoreCase(cacheImpl)) {
        return aerospikeCacheManager();
    } else if (CacheSupport.REDIS.equalsIgnoreCase(cacheImpl)) {
        return redisCacheManager();
    } else {
        return guavaCacheManager();
    }
}

我们的Aerospike控制器如下所示：

@ConditionalOnProperty(name = CacheSupport.CACHE_PROPERTY, havingValue = CacheSupport.AEROSPIKE)
@Controller
public class AerospikeController {
  @Autowired
    private AerospikeCacheManager aerospikeCacheManager;
}

事情进展顺利。当我添加以下代码来拦截aerospike呼叫的响应时间时，问题就出现了：

@Component

@面貌 公共类WebServiceResponsetTimeLogger{

private static final Logger LOG = LoggerFactory.getLogger(WebServiceResponseTimeLogger.class);

@Autowired
private AerospikeCacheManager cacheManager;

@PostConstruct
void init() {
    LOG.info("WebServiceRequestTimeLogger initialized");
}

public WebServiceResponseTimeLogger() {
    super();
}

@Pointcut("execution(* com.snapdeal.pie.web.aerospike.config.AerospikeCacheManager.*(..))")
public void pointcuts() {
}

@Around("pointcuts()")
public void logExternalCalls(ProceedingJoinPoint pjp) throws Throwable {
    long timeStartInMillisecs = System.currentTimeMillis();
    pjp.proceed();
    MethodSignature signature = (MethodSignature) pjp.getSignature();
    LOG.info("Time Taken to execute : {} {} is {} ms", new Object[] { signature, pjp.getArgs()[0], (System.currentTimeMillis() - timeStartInMillisecs) });
}

}

我得到以下例外：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.snapdeal.pie.web.aerospike.config.AerospikeCacheManager] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

从日志中可以看出：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.snapdeal.pie.web.aerospike.config.AerospikeCacheManager] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

检查是否在此代码中正确创建了bean缓存管理器

@Bean
public CacheManager cacheManager() throws IOException {
    String cacheImpl = env.getProperty(CacheSupport.CACHE_PROPERTY, String.class, "");
    if (CacheSupport.AEROSPIKE.equalsIgnoreCase(cacheImpl)) {
        return aerospikeCacheManager();

将@Qualifier（value=“cacheManager”）添加到AeospikeController中的自动连线cacheManager中，或将变量名称重命名为cacheManagerAdd@Qualifier（value=“cacheManager”）添加到AeospikeController中的自动连线cacheManager中，或将变量名称重命名为CacheManagery成功创建bean。当我删除方面代码时，一切正常。是的，bean创建成功。当我删除方面代码时，一切正常。
