infinispan 10.1没有为Java类型Java注册封送拆收器。util。ArrayList

Question

试图将列表对象存储在infinispan缓存中时，抛出了错误。我参考了一些论坛，也加入了白名单类，但仍然得到同样的错误

注意：远程托管服务器

import java.util.ArrayList;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;

import org.infinispan.client.hotrod.DefaultTemplate;
import org.infinispan.client.hotrod.RemoteCache;
import org.infinispan.client.hotrod.RemoteCacheManager;
import org.infinispan.client.hotrod.configuration.ConfigurationBuilder;
import org.infinispan.commons.api.CacheContainerAdmin;

代码：

// Setup up a clustered cache manager
    ConfigurationBuilder builder = new ConfigurationBuilder();
builder.addServer().host("127.0.0.1").port(11322).addJavaSerialWhiteList("java.util.List","java.util.ArrayList");
    // Connect to the server
    RemoteCacheManager cacheManager = new RemoteCacheManager(builder.build());
    // Create test cache, if such does not exist
    cacheManager.administration().withFlags(CacheContainerAdmin.AdminFlag.VOLATILE).getOrCreateCache("test123", DefaultTemplate.DIST_SYNC);
    // Obtain the remote cache
    RemoteCache<String, List<String>> cache = cacheManager.getCache("test123");
    List<String> test = new ArrayList();
    cache.put("key", test);

Answer 1

在添加.marshaller(new JavaSerializationMarshaller())之后工作。希望这个改变是正确的，如果有更好的选择，请发布

builder.addServer().host("127.0.0.1").port(ConfigurationProperties.DEFAULT_HOTROD_PORT).marshaller(new JavaSerializationMarshaller()).addJavaSerialWhiteList("java.util.List","java.util.ArrayList");

Answer 2

不幸的是，ProtoStream marshaller目前不支持ArrayList的直接编组，但这是为后续的ProtoStream发行版IPROTO-118计划的

要使用Infinispan的默认Protostream封送器封送ArrayList或任何Collection实现，需要将集合包装在用户定义的类中，并将其添加为字段。例如，以下类允许存储ArrayList：

public class Book {

   @ProtoField(number = 1, collectionImplementation = ArrayList.class)
   final List<String> authors;

   @ProtoFactory
   Book(List<String> authors) {
      this.authors = authors;
   }
}
