Question

我将Infinispan 9.4.0 / 9.4.1与Hot Rod Client和Protobuf协议结合使用时遇到问题，以便能够使用查询。

这是我的缓存配置：

<cache-container name="clustered" default-cache="RequestIndexed" statistics="false">
    <transport channel="cluster" lock-timeout="1000"/>
    <global-state/>
    <modules>

我的实体

public class EntityDemo implements Serializable {
    /** Class serial version UID. */
    private static final long serialVersionUID = 1L;

    private long id;

    private String name;

    private String value;

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getValue() {
        return value;
    }

    public void setValue(String value) {
        this.value = value;
    }

    public String getKey() {
        return String.valueOf(id);
    }
}

原始文件

package test.infinispan.entity;

option indexed_by_default = false;

message EntityDemo {
    /*@Field*/
    required int64 id = 1;
    /*@Field*/
    required string name = 2;
    optional string value = 3;
}

编组员

public class EntityDemoMarshaller implements Serializable, MessageMarshaller<EntityDemo> {
    /** Class serial version UID. */
    private static final long serialVersionUID = 1L;

    @Override
    public Class<? extends EntityDemo> getJavaClass() {
        return EntityDemo.class;
    }

    @Override
    public String getTypeName() {
        return "test.infinispan.entity.EntityDemo";
    }

    @Override
    public EntityDemo readFrom(ProtoStreamReader reader) throws IOException {
        final EntityDemo ed = new EntityDemo();
        ed.setId(reader.readLong("id"));
        ed.setName(reader.readString("name"));
        ed.setValue(reader.readString("value"));
        return null;
    }

    @Override
    public void writeTo(ProtoStreamWriter writer, EntityDemo ed) throws IOException {
        writer.writeLong("id", ed.getId());
        writer.writeString("name", ed.getName());
        writer.writeString("value", ed.getValue());
    }
}

缓存配置

<distributed-cache name="core.request" remote-timeout="3000" statistics-available="false">
    <memory>
        <object size="20" strategy="LRU"/>
    </memory>

        <key media-type="application/x-jboss-marshalling"/>
        <value media-type="application/x-jboss-marshalling"/>
    </encoding>
</distributed-cache>

我与Infinispan的连接

ConfigurationBuilder cbi = new ConfigurationBuilder();
cbi.addServers("localhost:11222");
cbi.marshaller(new ProtoStreamMarshaller());
RemoteCacheManager rcmi = new RemoteCacheManager(cbi.build());

SerializationContext sc = ProtoStreamMarshaller.getSerializationContext(rcmi);
FileDescriptorSource fds = new FileDescriptorSource();
fds.addProtoFiles("/proto/EntityDemo.proto");
sc.registerProtoFiles(fds);
sc.registerMarshaller(new EntityDemoMarshaller());

RemoteCache<String, String> metadataCache = rcmi.getCache(ProtobufMetadataManagerConstants.PROTOBUF_METADATA_CACHE_NAME);
metadataCache.put("/proto/EntityDemo.proto", readProtoFile("/proto/EntityDemo.proto"));

RemoteCache<String, EntityDemo> rci = rcmi.getCache("RequestIndexed");
rci.clear();
EntityDemo ei = new EntityDemo();
ei.setId(1);
ei.setName("DemoIndexed");
ei.setValue("DemoIndexed");
rci.put(ei.getKey(), ei);

QueryFactory qf = Search.getQueryFactory(rci);
Query q = qf.from(EntityDemo.class)
        .having("id").gte(1)
        .build();
q.list().stream().forEach(v -> System.out.println(v));

我将实体放在jar文件（infinispan-module.jar）中，然后将那个jar部署在Infinispan中。

当我尝试将对象放入缓存时，服务器中出现以下异常

更新2018-11-07

我有一个新问题。

我需要将侦听器与过滤器和转换器一起使用。当我只使用过滤器时，一切正常，但是当我添加转换器时，服务器端会出现异常。我只想接收在CREATE自定义事件中放入缓存中的对象。

过滤器类

public class RequestEventFilter implements Serializable, CacheEventFilter<String, EntityDemo> {
    /** Class serial version UID. */
    private static final long serialVersionUID = 1L;

    private final long filter;

    public RequestEventFilter(Object[] params) {
        this.filter = (Long) params[0];
    }

    @Override
    public boolean accept(String key, EntityDemo oldValue, Metadata oldMetadata, EntityDemo newValue, Metadata newMetadata, EventType eventType) {
        if (eventType.isCreate()) {
            if (newValue.getId() % filter == 0)
                return true;
        }
        return false;
    }
}

过滤器工厂类

@NamedFactory(name="request-event-filter-factory")
public class RequestEventFilterFactory implements CacheEventFilterFactory {

    public RequestEventFilterFactory() {
    }

    @Override
    @SuppressWarnings("unchecked")
    public CacheEventFilter<String, EntityDemo> getFilter(Object[] params) {
        return new RequestEventFilter(params);
    }
}

转换器类

public class RequestEventConverter implements Serializable, CacheEventConverter<String, EntityDemo, EntityDemo> {
    /** Class serial version UID. */
    private static final long serialVersionUID = 1L;

    public RequestEventConverter() {
    }

    @Override
    public EntityDemo convert(String key, EntityDemo oldValue, Metadata oldMetadata, EntityDemo newValue, Metadata newMetadata, EventType eventType) {
        if (newValue != null)
            return newValue;
        else
            return oldValue;
    }

}

转换器工厂

@NamedFactory(name="request-event-converter-factory")
public class RequestEventConverterFactory implements CacheEventConverterFactory {

    public RequestEventConverterFactory() {
    }

    @Override
    @SuppressWarnings("unchecked")
    public CacheEventConverter<String, EntityDemo, EntityDemo> getConverter(Object[] params) {
        return new RequestEventConverter();
    }
}

我的听众

@ClientListener(filterFactoryName="request-event-filter-factory", converterFactoryName="request-event-converter-factory", includeCurrentState = true, useRawData=false)
private class Listener {

    public Listener() {
    }

    @ClientCacheEntryCreated
    public void entryCreated(ClientCacheEntryCustomEvent<EntityDemo> event) {
        System.out.println("Entry created!");
        System.out.println(event.getEventData());
    }
}

我用此代码添加侦听器

this.cache.addClientListener(new Listener(), new Object[] {2L}), new Object[]{});

当我将新对象放入infinispan缓存中时，出现以下异常：

我已经搜索过infinispan文档，但找不到任何东西。

Answer 1

要能够通过Hot Rod使用查询，您不需要兼容模式，我可以看到您的缓存中有<compatibility enabled="true"/>。查询也不需要在服务器中部署实体。

关于兼容性模式，在Infinispan 9.4.0中已弃用，替代方式为http://infinispan.org/docs/stable/user_guide/user_guide.html#endpoint_interop。

最后，如果确实需要在缓存中存储未编组的对象，则需要在服务器中部署实体和编组器。要部署额外的protobuf编组器，请参阅：

http://infinispan.org/docs/stable/user_guide/user_guide.html#protostream_deployment

要部署实体，请参见：

http://infinispan.org/docs/stable/user_guide/user_guide.html#entities_deploy

Answer 2

您无需使用compat模式即可进行查询，正如其他答案在此处所述。因此，我将首先尝试不使用兼容模式。在Whithout兼容模式下，您也不再需要在服务器中部署实体和编组器，从而简化了一切并减少了发生错误的可能性。我已经看到您在EntityDemoMarshaller.readFrom中有一个小问题。它只是返回null而不是返回未编组的实体，因此仍然有可能破坏整个事情。请解决该问题，如果仍然失败，请使用新的stacktrace更新该问题；如果不再是问题，请将其关闭。

如果您的用例出于任何原因绝对需要兼容模式，请阅读用户指南中有关转码的内容，并改用它，因为不赞成使用兼容模式，并已将其替换为转码。
