Cannot find the cache named xxx for the builder in spring boot application

Question

I have a Spring boot application where I want to use spring bot cache on a repository method.I have specified @EnableCaching annotaion in my spring boot app, When I try to use @Cacheable annotation on my repository method, it throws error like

java.lang.IllegalArgumentException: Cannot find cache named 'cache' for Builder[public abstract java.util.Optional myRepoMethod(java.lang.String,java.lang.String)] caches=[cache] | key='' | keyGenerator='' | cacheManager='' | cacheResolver='' | condition='' | unless='' | sync='false' at org.springframework.cache.interceptor.AbstractCacheResolver.resolveCaches(AbstractCacheResolver.java:84) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.cache.interceptor.CacheAspectSupport.getCaches(CacheAspectSupport.java:224) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.cache.interceptor.CacheAspectSupport$CacheOperationContext.(CacheAspectSupport.java:669) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.cache.interceptor.CacheAspectSupport.getOperationContext(CacheAspectSupport.java:237) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.cache.interceptor.CacheAspectSupport$CacheOperationContexts.(CacheAspectSupport.java:570) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.cache.interceptor.CacheAspectSupport.execute(CacheAspectSupport.java:317) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.cache.interceptor.CacheInterceptor.invoke(CacheInterceptor.java:61) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:185) ~[spring-aop-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:212) ~[spring-aop-5.0.6.RELEASE.jar:5.0.6.RELEASE] at com.sun.proxy.$Proxy140.findByUserIdAndProduct(Unknown Source) ~[?:?]

I don't know where I have missed out !!

My repository method looks like ,

@Cacheable("cache")
Optional<ModelClass> findByUserIdAndProduct(String userId, String product);

Alternatively:

Add ehcache.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <config xmlns='http://www.ehcache.org/v3'>

        <persistence directory="${java.io.tmpdir}" />

        <!-- Default cache template -->
        <cache-template name="default">
            <expiry>
                <tti unit="hours">4</tti>
                <!-- <ttl unit="minutes">2</ttl> -->
            </expiry>
            <listeners>
                <listener>
                    <class>com.org.lob.support.LoggingTaskCacheListener</class>
                    <event-firing-mode>ASYNCHRONOUS</event-firing-mode>
                    <event-ordering-mode>UNORDERED</event-ordering-mode>
                    <events-to-fire-on>CREATED</events-to-fire-on>
                    <events-to-fire-on>EXPIRED</events-to-fire-on>
                    <events-to-fire-on>REMOVED</events-to-fire-on>
                    <events-to-fire-on>UPDATED</events-to-fire-on>
                </listener>
            </listeners>
            <resources>
                <heap unit="MB">10</heap>
                <offheap unit="MB">50</offheap>
                <disk persistent="true" unit="GB">1</disk>
            </resources>
            <!-- 
            <heap-store-settings>
                <max-object-graph-size>2000</max-object-graph-size>
                <max-object-size unit="kB">5</max-object-size>
            </heap-store-settings>
            -->
        </cache-template>

        <!-- Cache configurations -->
        <cache alias="books" uses-template="default" >
            <key-type>java.lang.String</key-type>
            <value-type>com.org.lob.project.repository.entity.Book</value-type>     
        </cache>

        <cache alias="files" uses-template="default" >
            <key-type>java.lang.String</key-type>
            <value-type>java.lang.String</value-type>       
        </cache>

    </config>

And add the following in application.properties.

# Cache
spring.cache.jcache.config=classpath:ehcache.xml

In my case, I want to use redis as the backend of cache storage.

I got the same error and resolved with the following config:

application.yml:

spring:
    redis:
        database: 0
        host: localhost
        password:
        port: 6379
    cache:
        type: redis
        redis:
            key-prefix: 'api::'
            # value in milliseconds
            time-to-live: 12000000

Don't forget to put the @EnableCaching annotation with the @SpringBootApplication annotation.

I have the same problem, this is my solution for Spring Boot + EHCache:

File ehcache.xml put in src/main/resources:

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="https://www.ehcache.org/ehcache.xsd" 
    updateCheck="true"
    monitoring="autodetect" 
    dynamicConfig="true">

   <diskStore path="/Volumes/Data/CACHE" />

    <defaultCache
        maxElementsInMemory="10000" 
        eternal="true"
        timeToIdleSeconds="120" 
        timeToLiveSeconds="120" 
        overflowToDisk="true"
        maxElementsOnDisk="10000000" 
        diskPersistent="true"
        diskExpiryThreadIntervalSeconds="120" 
        memoryStoreEvictionPolicy="LRU" />
    <!-- IMPORTANT: Change name to your name -->
    <cache 
        name="basicData" 
        maxElementsInMemory="500" 
        eternal="true"
        overflowToDisk="true" 
        timeToIdleSeconds="300" 
        timeToLiveSeconds="600"
        diskPersistent="true" 
        diskExpiryThreadIntervalSeconds="1"
        memoryStoreEvictionPolicy="LFU" />

</ehcache>

Spring Boot Cache Configuration:

@Configuration
@EnableCaching
public class CachingConfig { 
     
    @Bean
    public CacheManager cacheManager() {
        net.sf.ehcache.CacheManager ehCM = ehCacheCacheManager().getObject(); 
        CacheManager cacheManager = new EhCacheCacheManager(ehCM); 
        return cacheManager;
    }

    @Bean
    public EhCacheManagerFactoryBean ehCacheCacheManager() {
        EhCacheManagerFactoryBean cmfb = new EhCacheManagerFactoryBean();
        cmfb.setConfigLocation(new ClassPathResource("ehcache.xml"));
        cmfb.setShared(true);

        return cmfb;
    }
}

Java File example:

@Service
@Transactional
public class BasicDataCacheService {

    @Autowired
    private BasicDataDAO basicDataDAO;

    public BasicData getFromDB() {
        BasicData basicData = this.basicDataDAO.getMeta();
        basicData.sort();
        return basicData;
    }

    @CacheEvict(value = "basicData", allEntries = true)
    public void clearCache() {
    }

    @Cacheable("basicData")
    public BasicData getOrFindCache() {
        return getFromDB();
    }
}
