根据link,在spring boot中使用缓存的最简单配置是使用CacheManager(缓存Map将在此类中初始化):
@Configuration
@EnableCaching
public class CacheService extends CachingConfigurerSupport {
@Bean
public CacheManager concurrentMapCacheManager() {
ConcurrentMapCacheManager cmcm = new ConcurrentMapCacheManager();
return cmcm;
}
@Bean
@Primary
public CacheManager guavaCacheManager() {
GuavaCacheManager gcm = new GuavaCacheManager();
return gcm;
}
}
和serviceImpl.java
:
@Cacheable(cacheManager="guavaCacheManager")
@Override
public List<RoleVO> getDataForCreateNewOperator() {
...
}
但它抛出:
java.lang.IllegalStateException: No cache could be resolved for 'Builder[public java.util.List getDataForCreateNewOperator()] caches=[] | key='' | keyGenerator='' | cacheManager='guavaCacheManager' | cacheResolver='' | condition='' | unless='' | sync='false'' using resolver 'org.springframework.cache.interceptor.SimpleCacheResolver@38466d10'. At least one cache should be provided per cache operation.
编辑:
如果我在cacheManager中分配一个cacheName,并在建议的方法中使用它,那么异常就消失了。但是bean中的所有方法都会被缓存,而我只在一个方法上分配@Cacheable
。

我正在使用Ehcache,我有同样的问题,因为我有两个不同 缓存和Cacheable的名称。
Please make you use same name for cache and Cacheable.
@Cacheable("codetable")
<cache name="codetable"
maxEntriesLocalHeap="100"
maxEntriesLocalDisk="1000"
eternal="false"
timeToIdleSeconds="300"
timeToLiveSeconds="600"
memoryStoreEvictionPolicy="LFU"
transactionalMode="off">
<persistence strategy="localTempSwap" />
</cache>
