写写吧，这个项目配置搞的我着实有点火大，折腾了2天时间配置maven的pom文件。
背景：基于springboot技术，没有使用spring cloud全家桶，而是使用的grpc+consul的方式进行开发，原因是经过实测，grpc性能好于spring cloud全家桶，另外spring cloud全家桶开发的时候微服务调用代码编写比较麻烦，不如grpc可以直接一键自动生成，除了性能、开发麻烦，还有grpc支持异构语言，后期不管是用go语言开发服务供java调用，还是java开发服务供go等进行调用都很方便。
既然选择了不用spring cloud全家桶，服务发现与注册、健康检查、负载均衡这些就都需要找到对应的处理方法，这里使用的是国人开发的grpc-spring-boot-starter,项目地址为https://github.com/yidongnan/grpc-spring-boot-starter 。
项目使用IDEA进行创建，分别建立了几个子项目，基础项目的maven配置参数如下：

基础父项目配置内容就是上面这些，看上去稀松平常，这可是跳了数个坑才得到的结果，具体包括：grpc-spring-boot-starter这个项目，2.5.1版本引用的是grpc的1.22.2版本，然后grpc 1.22.2版本会自动加载一个叫做grpc-netty-shaded.jar的文件，不知道什么原因，只要类搜索路径里面有这个文件，一启动项目就报错，这玩意好像是想在它的所在路径下面找一堆jar依赖，这是第一个坑。第二个坑是com.google.guava这个包，最新版有些类已经移除掉了，也不知道是哪个jar依赖了这个东西，经过反复试验，grpc 1.23.0配合这个20.0版本是没有问题的。
其他还有找不到grpc-Channel之类的坑，后面慢慢说吧。
下面是grpc接口proto文件所在的项目，这些.proto文件需要经过protobuf插件编译以后才能使用，所以这个子项目的配置内容如下：

这个子项目没有什么坑，要说有的话就是项目路径不能有中文，必须把项目建到英文路径下面才能正常执行。
然后是提供微服务的项目，项目pom.xml文件内容如下:

配置文件内容没有太特殊的，然后是springboot的项目启动配置文件参数文件，内容如下：
#开发配置

application:
name: xxx_service
sleuth:

serviceName: xxx-${spring.application.name}
logging:
config: classpath:logback-dev.xml
server:
port: 8082
grpc:
server:
port: 9090看到最后那个grpc.server.port=9090没有，你要是不写，项目启动的时候它也会去9090端口进行监听，但是，微服务的调用端是无法知道到哪个端口去进行grpc调用的，必须把上面那个配置参数写上以后微服务的调用端才能知道去9090端口找微服务，巨坑！因为这个差点就放弃grpc+consul的方案了，因为consul去检查服务健康状态是基于8082端口去检测的，当时就特别纳闷，grpc的调用端怎么才能知道去到9090端口找微服务进行调用呢，写上这个参数以后再去consul里面看，会多出来一个TAG，里面注明了grpc服务端口在9090。
然后是调用端，这边就比较简单了，子项目pom.xml文件内容如下：

项目跑起来以后访问consul，里面可以看到注册的微服务名称及提供服务的IP地址，可以看到健康检查的情况，客户端需要访问微服务时，会自动从可用的微服务里面进行负载均衡调用，客户端会每隔10秒自动检测服务的可用性，发现服务不可用时就通过其他服务进行微服务调用。
