java - 如何在基于spring java的配置中设置ehcache.xml的位置？

Question

我的 spring 项目有这个基于 java 的 JPA 配置:

@Configuration
@EnableJpaRepositories(basePackageClasses = {PackageMarker.class})
@EnableTransactionManagement(proxyTargetClass = true)
@EnableCaching
public class FooJPAConfig implements CachingConfigurer {

    @Bean
    @Override
    public CacheManager cacheManager() {
        SimpleCacheManager cacheManager = new SimpleCacheManager();
        cacheManager.setCaches(Arrays.asList(new ConcurrentMapCache("default")));
        return cacheManager;
    }

    @Bean
    @Override
    public KeyGenerator keyGenerator() {
        return new DefaultKeyGenerator();
    }

    //...

}

如何告诉 spring 使用特定的 ehcache.xml 文件？

Answer 1

您需要更改cacheManager才能集成EhCache。您当前的代码不会使 EhCache 参与进来。

配置如下

@Configuration
@EnableJpaRepositories(basePackageClasses = {PackageMarker.class})
@EnableTransactionManagement(proxyTargetClass = true)
@EnableCaching
public class FooJPAConfig implements CachingConfigurer {

    @Bean
    public EhCacheManagerFactoryBean cacheFactoryBean() {
        EhCacheManagerFactoryBean ehCacheManagerFactoryBean = new EhCacheManagerFactoryBean();
        ehCacheManagerFactoryBean.setConfigLocation(new ClassPathResource("whatever-name.xml"));  //this is where you set the location of the eh-cache configuration file
        return ehCacheManagerFactoryBean;
    }

    @Bean
    @Override
    public CacheManager cacheManager() {
        EhCacheCacheManager cacheManager = new EhCacheCacheManager();
        cacheManager.setCacheManager(cacheFactoryBean().getObject());
        return cacheManager;
    }

    @Bean
    @Override
    public KeyGenerator keyGenerator() {
        return new DefaultKeyGenerator();
    }

}

您还必须将 spring-context-support 作为类路径的依赖项(适用于 Spring 3.2)

请注意，上面的代码激活 Spring -EhCache 集成，而不是 JPA - EhCache 集成。这意味着您可以在实体上使用 Spring 的 @Cacheable 而不是 EhCache 的 @Cache。
