1.定义proto文件
因为是测试和官网一样定义一个简单的hello.proto文件 2.maven插件配置
1添加依赖
propertiesproject.build.sourceEncodingUTF-8/project.build.sourceEncodinggrpc.version1.59.1/grpc.version!-- CURRENT_GRPC_VERSION --protobuf.version3.24.0/protobuf.versionprotoc.version3.24.0/protoc.version!-- required for JDK 8 --maven.compiler.source1.8/maven.compiler.sourcemaven.compiler.target1.8/maven.compiler.target/propertiesdependencyManagementdependenciesdependencygroupIdio.grpc/groupIdartifactIdgrpc-bom/artifactIdversion${grpc.version}/versiontypepom/typescopeimport/scope/dependency/dependencies/dependencyManagementdependenciesdependencygroupIdio.grpc/groupIdartifactIdgrpc-netty-shaded/artifactId!--version1.59.1/version--scoperuntime/scope/dependencydependencygroupIdio.grpc/groupIdartifactIdgrpc-protobuf/artifactId!--version1.59.1/version--/dependencydependencygroupIdio.grpc/groupIdartifactIdgrpc-services/artifactId/dependencydependencygroupIdio.grpc/groupIdartifactIdgrpc-stub/artifactId!--version1.59.1/version--/dependencydependency !-- necessary for Java 9 --groupIdorg.apache.tomcat/groupIdartifactIdannotations-api/artifactIdversion6.0.53/versionscopeprovided/scope/dependencydependencygroupIdcom.google.protobuf/groupIdartifactIdprotobuf-java/artifactIdversion${protobuf.version}/version/dependencydependencygroupIdcom.google.protobuf/groupIdartifactIdprotobuf-java-util/artifactIdversion${protobuf.version}/version/dependency/dependencies
2添加插件

这个插件在我的本地无法编译通过大家都知道maven编译不通过是没法执行接下来的命令执行编译是为了将proto文件生成对应的java代码。
3执行命令
mvn clean compile
结果是报错了具体错误没有记录。
4修改插件配置
参考java - How to use google protobuf compiler with maven-compiler-plugin - Stack Overflow
查阅资料将插件配置修改为 configurationadditionalProtoPathElementsadditionalProtoPathElement${project.basedir}/src/main/resources/additionalProtoPathElement/additionalProtoPathElementsprotocArtifactcom.google.protobuf:protoc:3.7.0:exe:${os.detected.classifier}/protocArtifact/configuration
再次执行编译还是不通过继续search。。。
找到io.github.ascopes下的protobuf-maven-plugin plugingroupIdio.github.ascopes/groupIdartifactIdprotobuf-maven-plugin/artifactId
lt;!ndash; version${protobuf-maven-plugin.version}/versionndash;gt;configurationprotocVersion${protobuf.version}/protocVersion/configurationexecutionsexecutiongoalsgoalgenerate/goal/goals/execution/executions/plugin 经过测试没有下载到io.github.ascopes#protobuf-maven-plugin插件这个插件也许是可以用的我没有切换maven仓库源只是在maven 仓库官网没找到而已果断放弃了。如果要使用这个插件需要注意一个默认约束你定义的proto文件位置src/main/protobuf
插件默认会从这个位置读取proto文件除非你修改插件配置。 继续寻找其他插件继续search。。。
功夫不负有心人果然找到了一款插件配置如下

他强调需要依赖 dependencygroupIdcom.google.protobuf/groupIdartifactIdprotobuf-java/artifactIdversion${project.basedir}/version/dependency
配置后插件后pom.xml编译通过 ,心里爽快多了。
继续执行命令编译
mvn clean compile
不幸的是又出现错误
Unsupported platform: protoc-3.24.0-osx-x86_64.exe
这个错误一看就是和protoc安装版本有关系我的是arm操作系统显示x86肯定不对。
我猜测自己的mac os安装的protobuf未生效造成的执行命令将protoc命令加入环境变量
$ source ~/.bash_profile
执行完后重新构建果真通过 在插件${project.basedir}/target/generated-sources指定的target下生成了我们需要的Java源码文件 ⚠️注意插件要求你的proto文件路径默认src/main/protobuf
关于Unsupported platform: protoc-3.24.0-osx-x86_64.exe错误应该还有以下解决办法issues链接如下针对mac os M1/M2

5配置插件生成java-grpc调用接口定义

执行重新构建
$ mvn clean compile
控制台打印如下 生成程序如下 以上针对Java版本的gRPC代码生成和官网不一样很容易理解希望给刷到的同学带来些许帮助。 插件protoc-jar-maven-plugin官方使用详细说明
