netty权威指南学习笔记七——编解码技术之GoogleProtobuf

　　首先我们来看一下protobuf的优点：

• 　　谷歌长期使用成熟度高；
• 　　跨语言支持多种语言如：C++,java，Python；
• 　　编码后消息更小，更利于存储传输；
• 　　编解码性能高；
• 　　支持不同协议版本的兼容性；
• 　　支持定义可选和必选字段；

　　接下来就让我们试用一下吧。

一、Protobuf开发环境搭建

　　下载Protobuf的Windows版本，本博主用的是protoc-3.6.1-win32.zip，解压后进入bin目录可以看到protoc.exe（下面的.proto文件是博主事先拉进来的）

然后我们打开cmd命令查看protoc是否安装成功，因本博主是尝试成功后接下来补充的博客，本博主配置了环境变量，但是运行成功后又把环境变量删掉了，仍可以编译生成java文件，所以可能不需要配置，但是读者如果没有配置运行不成功的话就还是配置一下。配置的方法就是在环境变量中path中添加protoc.exe所在的路径即可。

然后在cmd中输入命令 protoc和proto --version查看

OK，然后就可以对写的文件进行编译生成.java文件。在这里本博主遇到的几个坑，就是proto文件编写语法与java不同，比如，java字符串类型为String，赋值是加双引号的，而proto不认识，它的声明词是小写的string，其赋值是不需要加双引号的；在者也需要注意proto3也不同于proto2,采用proto3必须要写出其版本号syntax = "proto3";

具体变化可以参看https://www.cnblogs.com/asminfo/p/6782906.html的一部分。

接下来就可以用demo进行示范执行，代码如下：借用java模板加入进来，一定要注意语法不能写错否则执行命令就会报错

syntax = "proto3";
option java_package="com.protobuf";
option java_outer_classname="DemoProto";

message Demo{
    int32 subReqID=1;
    string userName=2;
    string productName=3;
    string address=4;
}

执行命令如下:protoc.exe ./源文件 --java_out=./+目标子文件夹

D:>protoc ./protobufc/bin/Demo.proto --java_out=./                                              这条命令执行后生成的com包在d:盘根目录下

D:>protoc ./protobufc/bin/Demo.proto --java_out=./protobufc/bin/                        这条命令执行后生成的com包在d:盘protobufc/bin/ 下

C:Userslitan>protoc ./d:protobufc/bin/Demo.proto --java_out=./                          这条命令执行报错说明执行命令的盘必须是源文件.proto和目标文件.java的同级或父级目录
./d:protobufc/bin/Demo.proto: No such file or directory                                          报错信息

以上我们将我们接下来需要的.proto转化为.java

这是因为代码里的String用了大写，大写改为小写后代码如下：

Req代码

syntax = "proto3";
option java_package="com.protobuf";
option java_outer_classname="SubscribeReqProto";

message SubscribeReq{
    int32 subReqID=1;
    string userName=2;
    string productName=3;
    repeated string address=4;
}

Resp代码

syntax = "proto3";
option java_package="com.protobuf";
option java_outer_classname="SubscribeRespProto";

message SubscribeResp{
    int32 subReqID=1;
    int32 respcode=2;
    string desc=3;
}

执行

执行后的目录及代码

 我们将后两个文件拷贝到相应工程中，发现报错，这里需要的是一个protobuf-java包，然后到官网找相应版本的包,该版本3.6.1的包在maven中可以找到，直接拿来用

<!-- https://mvnrepository.com/artifact/com.google.protobuf/protobuf-java -->
<dependency>
    <groupId>com.google.protobuf</groupId>
    <artifactId>protobuf-java</artifactId>
    <version>3.6.1</version>
</dependency>

maven自动更新完成后一切ok，到这里，protobuf环境已经可以使用了，即便将来再有新的pojo也可以轻松搞定。

二、测试protobuf的编解码效果

先看一下protobuf转为java后的代码，代码比较长折叠起来

 三、采用netty进行实例演示

至此，全部完成，折叠的代码主要为运行的不是很需要重点阅读的代码，折叠起来以减小篇幅，在书写代码的过程中，客户端和服务端编解码等框架在pipeline.add时候的对称性要注意，否则会导致服务跑不起来。

　　补充一下书上的注意事项：

　　ProtobufDecoder仅仅负责解码，它不支持读半包，因此，在ProtobufDecoder前面，一定要有能够处理读半包的解码器，有以下三种方式可以选择。

　　1.使用Netty提供的ProtobufVarint32FrameDecoder,它可以处理半包消息；

　　2.继承Netty提供的通用半包解码器LenthFieldBasedFrameDecoder;

　　3.继承ByteToMessageDecoder类，自己处理半包消息。
