PROSAGA码农传奇-EHcache-在没有XML配置的情况下将Ehcache CacheManager（v 3.x）转换为Spring CacheManager

<div class =“post-text”itemprop =“text”>
  <P>
    您不能简单地将ehcache CacheManager转换为spring CacheManager。
  </p>
  <P>
    您可以使用
     <code>
      org.ehcache.jsr107.EhcacheCachingProvider
    </code>
     得到一个
     <code>
      javax.cache.CacheManager
    </code>
     并把它给
     <code>
      org.springframework.cache.jcache.JCacheCacheManager
    </code>
     这是一个实现
     <code>
      org.springframework.cache.CacheManager
    </code>
     对于jcache（又名jsr107）。
  </p>
   <pre>
    <code>
      import java.util.HashMap;
import java.util.Map;

import javax.cache.CacheManager;
import javax.cache.Caching;

import org.ehcache.config.CacheConfiguration;
import org.ehcache.config.ResourcePools;
import org.ehcache.config.builders.CacheConfigurationBuilder;
import org.ehcache.config.builders.ResourcePoolsBuilder;
import org.ehcache.config.units.EntryUnit;
import org.ehcache.config.units.MemoryUnit;

import org.ehcache.jsr107.EhcacheCachingProvider;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.jcache.JCacheCacheManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableCaching
public class CacheConfig {

@Bean
    public JCacheCacheManager jCacheCacheManager() {
        JCacheCacheManager jCacheManager = new JCacheCacheManager(cacheManager());
        return jCacheManager;
    }

@Bean(destroyMethod = "close")
    public CacheManager cacheManager() {

ResourcePools resourcePools = ResourcePoolsBuilder.newResourcePoolsBuilder()
                .heap(2000, EntryUnit.ENTRIES)
                .offheap(100, MemoryUnit.MB)
                .build();

CacheConfiguration<Object,Object> cacheConfiguration = CacheConfigurationBuilder.newCacheConfigurationBuilder(
                Object.class,
                Object.class,
                resourcePools).
                build();

Map<String, CacheConfiguration<?, ?>> caches = new HashMap<>();
        caches.put("myCache", cacheConfiguration);

EhcacheCachingProvider provider = (EhcacheCachingProvider) Caching.getCachingProvider("org.ehcache.jsr107.EhcacheCachingProvider");
        org.ehcache.config.Configuration configuration = new DefaultConfiguration(caches, provider.getDefaultClassLoader());

return  provider.getCacheManager(provider.getDefaultURI(), (org.ehcache.config.Configuration) configuration);
    }

}

  <P>
    如果您使用的是spring-boot，它应该为您自动配置JCacheCacheManager。然后你可以使用
     <code>
      JCacheManagerCustomizer
    </code>
     配置缓存。
