idea使用Protobuf插件

1.protobuf簡介java

  Protobuf是一個靈活的、高效的用於序列化數據的協議。相比較XML和JSON格式,protobuf更小、更快、更便捷。Protobuf是跨語言的,而且自帶了一個編譯器(protoc),只須要用它進行編譯,能夠編譯成Java、python、C++等代碼,而後就能夠直接使用,不須要再寫其餘代碼,自帶有解析的代碼。一條消息數據,用protobuf序列化後的大小是json的10分之一,xml格式的20分之一,是二進制序列化的10分之一。python

2.安裝插件json

  在idea裏安裝插件Protobuf Supportmaven

3.配置ide

    </extension>
</extensions>
<!--protobuf插件-->
<plugin>

<version>0.5.1</version>
<configuration>

</configuration>
<executions>
<execution>

</executions>
</plugin>

4.建立proto文件測試

syntax = "proto3";
option java_package = "com.ynt.ai.activemq.protobuf";
option java_outer_classname = "PersonModel";

message Person {
    int32 id = 1;
    string name = 2;
    string email = 3;
}

5.生成java對象文件ui

  經過Protobuf插件的compile命令,以下圖所示,自動生成對象文件。google

6.測試idea

 PersonMsg.Person person = PersonMsg.Person.newBuilder().setId(2).setName("test")
                .setEmail("test@163.com").build();
 byte[] results = person.toByteArray();
 for (byte b : results) {
   log.info(String.valueOf(b));
 }
