### 定义`.proto`文件 ###

namespace java com.zjw.thrift.helloworld.gen
    
    service  GreetingService {
      string sayHello(1:string name)
    }

### 生成代码 ###

thrift -r --gen java java/com/zjw/thrift/helloworld/hello.thrift

### Maven依赖 ###

<dependency>
     <groupId>org.apache.thrift</groupId>
     <artifactId>libthrift</artifactId>
     <version>0.13.0</version>
    </dependency>

### Java代码 ###
