我有一个带有 Spring Cache 的系统，其中有多个类加载器。实际上我使用ehcache，它工作正常：

@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);
    }
}

我正在尝试更改为点燃：

@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)工作正常但在我做之后objectRepository.get("2", com.test.ClassInClassLoader2.class)我收到错误：

我尝试使用DeploymentMode.ISOLATED，DeploymentMode.PRIVATE但它们不能使用igniteConfiguration.setPeerClassLoadingEnabled(true)，所以我必须手动注册所有类，我没有找到如何使用 LocalDeploymentSpi，我尝试使用igniteConfiguration.getDeploymentSpi()但它为空，当我创建它时就像 Ignite 忽略那里的课程。

我不建议对域模型类使用对等类加载。相反，您应该使所有类在所有节点的类路径上可用，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，缓存数据将默认以二进制格式存储，因此即使禁用对等类加载，您也不必在服务器节点上部署类。
