Spring Boot2 系列教程Spring Boot 整合 Ehcache

@Configuration
@EnableCaching
public class CacheConfig {
 
    @Bean
    public CacheManager cacheManager() {
        return new EhCacheCacheManager(ehCacheCacheManager().getObject());
    }
 
    @Bean
    public EhCacheManagerFactoryBean ehCacheCacheManager() {
        EhCacheManagerFactoryBean cacheManagerFactoryBean = new EhCacheManagerFactoryBean();
        cacheManagerFactoryBean.setConfigLocation(new ClassPathResource("ehcache.xml"));
        cacheManagerFactoryBean.setShared(true);
        return cacheManagerFactoryBean;
    }
 
    @Bean
    public Cache sampleCache() {
        return new Cache(new CacheConfiguration("sampleCache", 5000).eternal(true).overflowToDisk(false));
    }
}

这个配置类定义了如何在Spring Boot应用程序中整合Ehcache。首先，它配置了一个CacheManager，这是Spring的缓存管理器，它委托Ehcache进行实际的缓存操作。然后，它定义了一个EhCacheManagerFactoryBean，这是Spring用来创建Ehcache的CacheManager的。最后，它定义了一个名为"sampleCache"的Ehcache缓存配置。
