7.netty集成Marshaling序列化包

1.介绍

JBoss Marshaling是一个java对象的序列化包,是对jdk默认序列化框架的一个优化实现。保持和Serializable接口兼容,同时增加了一些可调的参数和附加的特性

2.Marshaling开发环境

这里只需要用到Marshaling的序列化库类：

<!-- https://mvnrepository.com/artifact/org.jboss.marshalling/jboss-marshalling --><dependency>    <groupId>org.jboss.marshalling</groupId>    <artifactId>jboss-marshalling</artifactId>    <version>1.3.0.GA</version></dependency><dependency>    <groupId>org.jboss.marshalling</groupId>    <artifactId>jboss-marshalling-serial</artifactId>    <version>1.3.0.GA</version>    <scope>test</scope></dependency>

3.netty集成

创建解码器和编码器工厂类

package com.tyf.netty;import org.jboss.marshalling.MarshallerFactory;import org.jboss.marshalling.Marshalling;import org.jboss.marshalling.MarshallingConfiguration;import io.netty.handler.codec.marshalling.DefaultMarshallerProvider;import io.netty.handler.codec.marshalling.DefaultUnmarshallerProvider;import io.netty.handler.codec.marshalling.MarshallerProvider;import io.netty.handler.codec.marshalling.MarshallingDecoder;import io.netty.handler.codec.marshalling.MarshallingEncoder;import io.netty.handler.codec.marshalling.UnmarshallerProvider;//静态工厂public final class MarshallingCodeCFactory {//创建解码器public static MarshallingDecoder buildDecoder(){//工厂类：serial由jar包提供支持表示创建的是java序列化工厂final MarshallerFactory factory = Marshalling.getProvidedMarshallerFactory("serial");//配置类,设置一些基本配置final MarshallingConfiguration config = new MarshallingConfiguration();config.setVersion(5);UnmarshallerProvider provider = new DefaultUnmarshallerProvider(factory, config);//返回解码器MarshallingDecoder decoder = new MarshallingDecoder(provider, 1024);return decoder;}//创建编码器public static MarshallingEncoder buildEncoder(){//工厂类final MarshallerFactory factory = Marshalling.getProvidedMarshallerFactory("serial");//配置类,设置一些基本配置final MarshallingConfiguration config = new MarshallingConfiguration();config.setVersion(5);MarshallerProvider provider = new DefaultMarshallerProvider(factory, config);//返回解码器MarshallingEncoder encoder = new MarshallingEncoder(provider);return encoder;}}
