本次案例主要测试将百度AI开放平台Java SDK整合到自己的工程项目中，并就对其中感兴趣的模块做测试

### 在控制台创建应用 ###

### 下载Baidu-AIP/java-sdk ###

为了方便学习，可通过下载源码的方式进行引入，也可通过maven依赖的方式引入

<dependency>
        <groupId>com.baidu.aip</groupId>
        <artifactId>java-sdk</artifactId>
        <version>4.8.0</version>
    </dependency>

配置好本地git初始化环境，执行命令，$ git clone https://github.com/Baidu-AIP/java-sdk.git，完成sdk包的下载

在IDEA中导入项目

### 编写测试案例 ###

在client包下编写Sample类，作为测试客户端。

AipNlp是自然语言处理的Java客户端，为使用自然语言处理的开发人员提供了一系列的交互方法。

用户可以参考如下代码新建一个AipNlp,初始化完成后建议**单例使用**,避免重复获取access\_token

单例获取客户端：

package com.jyycode.baidu_aip.client;
    
    import com.baidu.aip.nlp.AipNlp;
    
    /** 获取单例客户端
     * @author Jiayuan
     * @version 1.0
     * @description:
     * @time 11/16/2018 3:44 PM
     */
    public class GetClient {
    
        private static AipNlp client = null;
    
        private GetClient(){};
    
        public static AipNlp getClient(String APP_ID,String API_KEY,String SECRET_KEY ){
            if(client == null){
                client = new AipNlp(APP_ID,API_KEY,SECRET_KEY);
                return client;
            }
            return client;
        }
    
    }

（中文分词）主程序：

package com.baidu.aip.client;
    
    import com.baidu.aip.nlp.AipNlp;
    import org.json.JSONObject;
    
    /** 百度AI开放平台客户端测试
     * @author Jiayuan
     * @version 1.0
     * @description:
     * @time 11/16/2018 3:05 PM
     */
    public class Sample {
    
        public static final String APP_ID = "INPUT_YOUR_APP_ID_HERE";
        public static final String API_KEY = "INPUT_YOUR_API_KEY_HERE";
        public static final String SECRET_KEY = "INPUT_YOUR_SECRET_KEY_HERE";
    
    
        public static void main(String[] args) {
            //初始化一个AipNlp
            AipNlp client = GetClient.getClient(APP_ID,API_KEY,SECRET_KEY);
            //可选，设置网络参数
            client.setConnectionTimeoutInMillis(2000);
            client.setSocketTimeoutInMillis(60000);
    
            //可选：设置网络连接参数
            //client.setHttpProxy("proxy_host",proxy_port);
            //client.setSocketProxy("proxy_host",proxy_port);
    
            //可选：设置log4j日志输出格式，若不设置，则使用默认配置
            //System.setProperties("aip.log.conf","path/to/your/log4j.proprties");
    
            //调用接口
            String text = "百度是一家高科技公司";
            JSONObject res = client.lexer(text,null);
            System.out.println(res.toString());
        }
    }

从服务端得到返回结果：

{
    	"log_id": 4810127541569104400,
    	"text": "百度是一家高科技公司",
    	"items": [{
    		"formal": "",
    		"loc_details": [],
    		"item": "百度",
    		"pos": "",

    		"byte_length": 2,

    	}, {

    	}, {

    		"pos": "n",
    		"ne": "",

    		"byte_length": 6,
    		"byte_offset": 10,
    		"uri": ""
    	}, {
    		"formal": "",
    		"loc_details": [],
    		"item": "公司",
    		"pos": "n",
    		"ne": "",
    		"basic_words": ["公司"],
    		"byte_length": 4,
    		"byte_offset": 16,

    	}]
    }
