Question

我有一个带有Spring Cache的系统，里面有多个类加载器。实际上我使用ehcache并且工作正常：

@Component
public class ObjectRepository extends MongoRepository<Object> {
// -------------------------- OTHER METHODS --------------------------

    @Override
    @Cacheable(value = "object", key = "#p0+#p1.name")
    public Object get(String id, Class<? extends Object> clazz) {
        return super.get(id, clazz);
    }

    @Override
    @CacheEvict(value = "object", key = "#p0+#p1.name")
    public void remove(String id, Class<? extends Object> clazz) {
        super.remove(id, clazz);
    }

    @Override
    @CacheEvict(value = "object", key = "#p0+#p0.class.name")
    public void save(Object object) {
        super.save(object);
    }
}

我试图改变点燃：

@Bean
@SuppressWarnings("unchecked")
public CacheManager cacheManager() {
    SpringCacheManager springCacheManager = new SpringCacheManager();
    IgniteConfiguration igniteConfiguration = new IgniteConfiguration();
    igniteConfiguration.setPeerClassLoadingEnabled(true);
    igniteConfiguration.setIncludeEventTypes(org.apache.ignite.events.EventType.EVTS_TASK_EXECUTION);
    springCacheManager.setConfiguration(igniteConfiguration);
    return springCacheManager;
}

由于多个类加载器我收到错误，当我objectRepository.get("1", com.test.ClassInClassLoader1.class)工作正常但我做objectRepository.get("2", com.test.ClassInClassLoader2.class)后我收到错误：

我尝试使用DeploymentMode.ISOLATED和DeploymentMode.PRIVATE，但它们不能与igniteConfiguration.setPeerClassLoadingEnabled(true)一起使用，所以我必须手动注册所有课程，我还没有找到如何做到这一点使用LocalDeploymentSpi，我尝试使用igniteConfiguration.getDeploymentSpi()，但它是null，当我创建它时，就像Ignite忽略了那里的类。

我不建议对域模型类使用对等类加载。相反，您应该在所有节点的类路径上提供所有类，并关闭对等类加载（igniteConfiguration.setPeerClassLoadingEnabled(false)）。

另请注意，从即将发布的Ignite 1.5开始，默认情况下缓存数据将以二进制格式存储，因此即使禁用了对等类加载，也不必在服务器节点上部署类。 / p>
