dubbo官网实例（IDL定义跨语言服务）编译问题整理-创新互联

dubbo官网的如下实例编译问题整理
https://cn.dubbo.apache.org/zh/docs3-v2/java-sdk/quick-start/idl/

报dubbo-compiler缺失，使用手动安装如下jar到mvn仓库

mvn install:install-file -DgroupId=org.apache.dubbo -DartifactId=dubbo-compiler -Dversion=3.1.5-SNAPSHOT -Dpackaging=jar -Dfile=/Users/baiyan3/Downloads/dubbo-3.1/dubbo-compiler/target/dubbo-compiler-3.1.5-SNAPSHOT.jar

下载dubbo
https://github.com/apache/dubbo
执行打包命令
mvn package -Dmaven.test.skip=true
将自动把dubbo每个组件的jar包安装到mvn的repository目录下

按照
https://cn.dubbo.apache.org/zh/docs3-v2/java-sdk/quick-start/idl/
这个说明的pom文件编译会出错

当然使用protobuf 需要安装protoc命令

Invalid multicast address /127.0.0.1, ipv4 multicast address scope: 224.0.0.0 - 239.255.255.255

修改如下代码
src/main/java/org/apache/dubbo/MyDubboServer.java
src/main/java/org/apache/dubbo/MyDubboClient.java

new RegistryConfig("zookeeper://127.0.0.1:2181")

同时需要启用zookeeper服务，借用下kafka带的zookeeper服务
bin/zookeeper-server-start.sh config/zookeeper.properties

如果maven plugin 编译proto文件报错，手动编译测试看下报错信息
protoc -I=/tri-stub-demo/src/main/proto --java_out=/java/tri-stub-demo/target/tmp/ /java/tri-stub-demo/src/main/proto/hello.proto

官网实例中调整完的pom.xml内容如下
