Step By Step

1、创建阿里云账号并开通机器翻译服务，具体可参考https://help.aliyun.com/document_detail/310982.html；

2、获取阿里云账号的AccessKey ID 和AccessKey Secret（可通过菜单栏右上角控制台进入，再点击个人头像，进入Accesskey管理即可查看）如下图；

3、创建Maven项目，添加Pom依赖

<dependency>
 <groupId>com.aliyun</groupId>
 <artifactId>aliyun-java-sdk-core</artifactId>
 <version>4.5.13</version>
</dependency>

4、Java Code Sample

import com.aliyuncs.CommonRequest;

import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
//机器翻译-机器翻译通用版调用指南
public class TranslateGeneralCommon {

    public static DefaultProfile profile = DefaultProfile.getProfile("cn-shanghai", "<AccessKey ID>", "<AccessKey Secret>");
   public static DefaultAcsClient client = new DefaultAcsClient(profile);

   public static void main(String[] args) {

        CommonRequest request  = new CommonRequest();
       request.setSysDomain("mt.aliyuncs.com");
       request.setSysAction("TranslateGeneral");
       request.setSysVersion("2018-10-12");
       request.setSysMethod(MethodType.POST);
       request.putQueryParameter("FormatType","text");
       request.putQueryParameter("Scene","general");
       request.putQueryParameter("SourceLanguage","zh");
       request.putQueryParameter("TargetLanguage","en");
       request.putQueryParameter("SourceText","你好");

       try {

            CommonResponse response = client.getCommonResponse(request);
           System.out.println(response.getData());
       } catch (ClientException e) {

            e.printStackTrace();
       }

    }

}

5、运行结果

注意事项

关于version版本参数，可通过阿里云机器翻译通用版原版SDK中的Node.js查看：
