idea 编译protobuf 文件的设置使用

忘是亡心i 2022-12-03 05:17 947阅读 0赞

protobuf 是一种数据格式，文件是.proto 格式的，有时需要编译成java 文件 ，目前流行 idea 工具开发并编译。那么应该怎么准备环境呢？我这有两种方案：下载idea插件编译和通过maven 编译：

二者相同的步骤如下：idea 下载插件  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmRhbzE1OA_size_16_color_FFFFFF_t_70][]

一、下载idea插件编译：

1、安装成功后重启：出现以下按钮说明安装成功。

2、官网下载protobuf 编译工具：protoc-3.11.8-win64.rar,解压打开后显示：

例如：   D:\\Program Files\\protoc-3.11.4-win64\\bin\\proto.exe

3、点开 Idea上插件  Google ProtobufTool 按钮，点击setting 设置编译相关目录  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmRhbzE1OA_size_16_color_FFFFFF_t_70 2][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmRhbzE1OA_size_16_color_FFFFFF_t_70 3][]

4、通过有边的Browse 按钮选择相应目录：

protoc\_path :就是刚刚下载的工具的目录+命令（=后面是需要编译的.proto 文件的目录），

比如： D:\\Program Files\\protoc-3.11.4-win64\\bin\\proto.exe  -I=E:\\ideaProject\\nmp-sdk\\nmp-sdk\\proto

protofile\_path:需要编译的.proto 文件的目录

out\_path :编译生成的java文件输出的目录

5、点击成功后进入这个页面：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmRhbzE1OA_size_16_color_FFFFFF_t_70 4][]

6、选择一些文件点击Gen  就会编译  如图 ：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmRhbzE1OA_size_16_color_FFFFFF_t_70 5][]

7、编译成功图：

二、maven 编译方案 下篇详细介绍，这个方案比较简单易用

1、pom.xml 中引用相关jar:

<dependency>
        <groupId>com.google.protobuf</groupId>
        <artifactId> protobuf-java</artifactId>
        <version>3.9.0</version>
    </dependency>
    
    <dependency>
        <groupId>io.grpc</groupId>
        <artifactId>grpc-core</artifactId>
        <version>1.6.1</version>
    </dependency>
    <dependency>
        <groupId>io.grpc</groupId>
        <artifactId>grpc-protobuf-lite</artifactId>
        <version>1.6.1</version>
    </dependency>
    <dependency>
        <groupId>io.grpc</groupId>
        <artifactId>grpc-protobuf</artifactId>
        <version>${grpc.version}</version>
    </dependency>

插件需要的信息

<plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
                
                <plugin>
                    <groupId>org.xolstice.maven.plugins</groupId>
                    <artifactId>protobuf-maven-plugin</artifactId>
                    <version>0.5.1</version>
                    <configuration>
                        
    
                        
                        <protoSourceRoot>${project.basedir}/src</protoSourceRoot>
                      
                        
                 
                        <outputDirectory>${project.build.sourceDirectory}</outputDirectory>
                 
                        <clearOutputDirectory>false</clearOutputDirectory>
    
                        
                        <protocArtifact>com.google.protobuf:protoc:${protobuf.version}:exe:${os.detected.classifier}</protocArtifact>
                        <pluginId>grpc-java</pluginId>
                        <pluginArtifact>io.grpc:protoc-gen-grpc-java:${grpc.version}:exe:${os.detected.classifier}</pluginArtifact>
                    </configuration>
                    <executions>
                        <execution>
                            <goals>
                                <goal>compile</goal>
                                <goal>compile-custom</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>

`extensions 扩展配置：`

<extensions>
        <extension>
            <groupId>kr.motd.maven</groupId>
            <artifactId>os-maven-plugin</artifactId>
            <version>1.5.0.Final</version>
        </extension>
    </extensions>

`grpc 配置`

<grpc.version>1.6.1</grpc.version>
    
    <protobuf.version>3.9.0</protobuf.version>

2、引入成功后打开maven插件，点击此处，生成相应的java文件：

（根据个人需求，我这里配置这个：<protoSourceRoot>$\{project.basedir\}/proto</protoSourceRoot>）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmRhbzE1OA_size_16_color_FFFFFF_t_70 7][]

3、然后把相关java文件打成单独的jar 包：

（根据个人需求，我这里配置这个：<protoSourceRoot>$\{project.basedir\}/src</protoSourceRoot>）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmRhbzE1OA_size_16_color_FFFFFF_t_70 8][]

4、此处编译成功，最后对该项目pom文件里的标签整体解析一下，加深大家的理解：
