再次运行
Maven
构建命令以确保所有代码都能编译：
mvn -DskipTests package
0.4.2.4
测试
gRPC
服务器
现在，
gRPC
服务器已准备好进行测试了。
在本练习中，我们将重用在本介
绍中前面部分创建的
C#gRPC
客户端：
1.
使用
Maven
构建并启动
gRPC
服务器：
mvn -DskipTests package exec:java -Dexec.mainClass=io.dapr.App
2.
启动一个
Dapr
边车。
请注意在这种情况下（应用）协议设置成了
grpc
，
并且使用了
echo a
的占位命令，因为我们要连接到一个现有的进程上去：
dapr --app-id hello-dapr --app-port 8090 --protocol grpc --grpc-port
3500 echo a
3.
在
Visual Studio
中运行
C# gRPC
客户端。
你应该看到
gRPC
服务器记录
的请求，以及返回给客户端的“
Hello
，
World!
”消息。
在结束本章节之前，让我们简要地研究一下
Dapr
的另一个功能：绑定，这是
激活编写平台无关代码的关键。
0.5
绑定
绑定使你可以将应用绑定到不同的事件源或目标上去。
这样，你就可以编写
与平台无关的代码了，并且可以动态地适配不同的环境和上下文。例如，你
可以使用输入绑定（
input binding
）绑定到
Azure Blob
存储容器，并在新的
