1. 引入jar包 <dependency>
<groupId>org.jboss.marshalling</groupId>
<artifactId>jboss-marshalling</artifactId>
<version>1.4.10.Final</version>
</dependency>
<dependency>
<groupId>org.jboss.marshalling</groupId>
<artifactId>jboss-marshalling-serial</artifactId>
<version>1.4.10.Final</version>
</dependency>
|
2.编写编码解码程序 public final class MarshallingCodeCFactory {
/**
* 创建Jboss Marshalling解码器MarshallingDecoder
* @return MarshallingDecoder
*/
public static MarshallingDecoder buildMarshallingDecoder() {
//首先通过Marshalling工具类的精通方法获取Marshalling实例对象 参数serial标识创建的是java序列化工厂对象。
final MarshallerFactory marshallerFactory = Marshalling.getProvidedMarshallerFactory("serial");
//创建了MarshallingConfiguration对象，配置了版本号为5
final MarshallingConfiguration configuration = new MarshallingConfiguration();
configuration.setVersion(5);
//根据marshallerFactory和configuration创建provider
UnmarshallerProvider provider = new DefaultUnmarshallerProvider(marshallerFactory, configuration);
//构建Netty的MarshallingDecoder对象，俩个参数分别为provider和单个消息序列化后的最大长度
MarshallingDecoder decoder = new MarshallingDecoder(provider, 1024 * 1024 * 1);
return decoder;
}
/**
* 创建Jboss Marshalling编码器MarshallingEncoder
* @return MarshallingEncoder
*/
public static MarshallingEncoder buildMarshallingEncoder() {
final MarshallerFactory marshallerFactory = Marshalling.getProvidedMarshallerFactory("serial");
final MarshallingConfiguration configuration = new MarshallingConfiguration();
configuration.setVersion(5);
MarshallerProvider provider = new DefaultMarshallerProvider(marshallerFactory, configuration);
//构建Netty的MarshallingEncoder对象，MarshallingEncoder用于实现序列化接口的POJO对象序列化为二进制数组
MarshallingEncoder encoder = new MarshallingEncoder(provider);
return encoder;
}

3.使用 socketChannel.pipeline().addLast(MarshallingCodeCFactory.buildMarshallingDecoder());
socketChannel.pipeline().addLast(MarshallingCodeCFactory.buildMarshallingEncoder());
|
4.注意事项 要传输的对象必须实现原生的序列化
| public class RpcRequest implements Serializable { } |
