将ehcache3与Spring4结合使用

Question

有人可以帮助通过 xml 使用 Spring

CacheManager

创建支持 Ehcache 的

JCacheCacheManager

吗？我有这样的东西。不知道如何为 Ehcache3 创建

javax.cache.CacheManager

。

<bean id="myCacheManager"
    class="org.springframework.cache.jcache.JCacheCacheManager">
    <property name="cacheManager" value="..." />
</bean>

谢谢！

Answer 1

建议的方法是使用

org.springframework.cache.jcache.JCacheManagerFactoryBean

，您可以在其中注入

URI

、

Properties

和

ClassLoader

。然后，该工厂 bean 将使用标准 JCache

Caching

类来创建

javax.cache.CacheManager

。

对于 Ehcache，

URI

用于指向

ehcache.xml

，然后配置

CacheManager

。

因此扩展您的示例配置：

<bean id="jCacheManager" class="org.springframework.cache.jcache.JCacheManagerFactoryBean">
  <property name="cacheManagerUri" value="file://path/to/ehcache.xml"/>
</bean>
<bean id="myCacheManager" class="org.springframework.cache.jcache.JCacheCacheManager">
  <property name="cacheManager" ref="jCacheManager" />
</bean>

Answer 2

@Configuration
@EnableCaching
public class CacheConfig {

  @Bean
  public JCacheCacheManager jCacheCacheManager() throws IOException {
    return new JCacheCacheManager(cacheManager());
  }

  @Bean(destroyMethod = "close")
  public javax.cache.CacheManager cacheManager() throws IOException {
    XmlConfiguration xmlConfig = new XmlConfiguration(new ClassPathResource("ehcache.xml").getURL());
    EhcacheCachingProvider provider = (EhcacheCachingProvider) Caching.getCachingProvider();
    return provider.getCacheManager(provider.getDefaultURI(), xmlConfig);

  }

}

Answer 3

@Configuration
@EnableCaching
public class CacheConfig {

    @Bean
    public JCacheCacheManager jCacheCacheManager(JCacheManagerFactoryBean jCacheManagerFactoryBean){
        JCacheCacheManager jCacheCacheManager = new JCacheCacheManager();
        jCacheCacheManager.setCacheManager(jCacheManagerFactoryBean.getObject());
        return jCacheCacheManager;
    }

    @Bean
    public JCacheManagerFactoryBean jCacheManagerFactoryBean() throws URISyntaxException {
        JCacheManagerFactoryBean jCacheManagerFactoryBean = new JCacheManagerFactoryBean();
        jCacheManagerFactoryBean.setCacheManagerUri(getClass().getResource("/ehcache.xml").toURI());
        return jCacheManagerFactoryBean;
    }
}

Answer 4

我用 spring 6 和 ehcache 3、jdk17 尝试这个

 <bean id="ehcache" class="org.springframework.cache.jcache.JCacheManagerFactoryBean">
        <property name="cacheManagerUri" value="classpath:ehcache.xml"/>
 </bean>

但是我有这个错误。我不明白为什么它搜索 javax.知道我在 pom 中有 lib jakarta.xml.bind-api
