【问题描述】：

使用的 Spring Boot 版本： 1.2.3

我们正在基于如下属性创建 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();
    

我们有一个 AerospikeController，如下所示：

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

一切正常。当我添加以下代码以拦截 aerospike 调用的响应时间时，问题就出现了：

@Component

@Aspect 公共类 WebServiceResponseTimeLogger

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) );

我遇到了异常：

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.

【问题讨论】：

在 AeospikeController 中将 @Qualifier(value = "cacheManager") 添加到自动装配的 CacheManager 或将变量名重命名为 cacheManager

【参考方案1】：

从它说的日志中：

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. Dependency annotations: @org.springframework.beans.factory.annotation.Autowired(required=true)

检查是否在此代码中正确创建了 bean AerospikeCacheManager。

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

【讨论】：

是的，bean 已成功创建。当我删除方面代码时，一切正常。
