springboot项目中，ehcache报错，需要CacheManager单例的解决办法

Another CacheManager with same name ‘default‘ already exists in the same VM. Please provide unique names for each CacheManager in the config or do one of following:

@Configuration
public class EhCacheConfig {

//    @Bean
//    public CacheManager getCacheManager() {
//        
//        return  CacheManager.create("classpath:ehcache.xml");
//    }
    @Bean(name = "demo")
    public CacheManager getCacheManagerDemo() {
        return  CacheManager.create("classpath:ehcache2.xml");
    }
}

xml version="1.0" encoding="UTF-8"?>
ehcache name="demo"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"
updateCheck="false">

    
    diskStore path="D:\44test\ehcache" />

    defaultCache maxElementsInMemory="1000"
        maxElementsOnDisk="10000000" eternal="false" overflowToDisk="true"
        timeToIdleSeconds="120" timeToLiveSeconds="120"
        diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU">
    defaultCache>
     
   
    
ehcache>

@Cacheable(cacheManager = "demo")
    public List queryAll() {
        // TODO Auto-generated method stub
        return this.userMapper.queryAll();
    }

@SpringBootApplication
@MapperScan(basePackages = {"cn.taotao.dao"})
@EnableCaching
public class DemoApplication {

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

}
