导语：效果图创建一个AI应用https://ai.qq.com/cgi-bin/console_overview 登录腾讯AI，创建并勾选相关接口即可。记得复制APPID APPKEY 使用Java接入该功能创建一个SpringMVC工程

效果图

创建一个AI应用

https://ai.qq.com/cgi-bin/console_overview 登录腾讯AI，创建并勾选相关接口即可。

记得复制APPID APPKEY

使用Java接入该功能

创建一个SpringMVC工程，包含上传相关jar。或者SpringBoot工程也行。鄙人后端还在完善并没有完全开源。具体可以参考https://gitee.com/xshuai/xai 项目

Java调用腾讯AI接口。小帅丶已经封装成SDK。也是开源的 https://gitee.com/xshuai/taip

如果使用maven搭建。直接pom引入即可哦

<!-- https://mvnrepository.com/artifact/cn.xsshome/taip --> <dependency>     <groupId>cn.xsshome</groupId>     <artifactId>taip</artifactId>     <version>4.2.1</version> </dependency>

FaceMergeController（后端处理代码）

import java.util.Iterator; import org.apache.log4j.Logger; import org.springframework.context.annotation.Scope; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.multipart.MultipartFile; import org.springframework.web.multipart.MultipartHttpServletRequest; import cn.xsshome.taip.ptu.TAipPtu; /** * 人脸融合接口 * url:http://www.xxx.com/facemerge/uploadFM */ @Controller @RequestMapping(value="/facemerge") @Scope("prototype") public class FaceMergeController extends BaseController{ 	private static final Logger logger = Logger.getLogger(FaceMergeController.class); 	/** 	 * 人脸融合 	 * @throws Exception 	 */ 	@RequestMapping(value="/uploadFM",method=RequestMethod.POST) 	public void UploadBDANIMAL()throws Exception{ 		TAipPtu aipPtu = new TAipPtu("APPID", "APPKEY"); 		String model = request.getParameter("model"); 		logger.info("model的值是===="+model); 		String model = request.getParameter("model"); 		logger.info("model的值是===="+model); 		    String result = ""; 		    MultipartHttpServletRequest mpRequest = (MultipartHttpServletRequest)this.request; 		    Iterator iter = mpRequest.getFileNames(); 		    MultipartFile file = null; 		    while (iter.hasNext()) { 		      file = mpRequest.getFile((String)iter.next()); 		      if ((file != null) && (file.getSize() != 0L)){ 		        byte[] image = file.getBytes(); 		        String apiPtuResult = aipPtu.faceMerge(image,Integer.parseInt(model)); 		        PrintUtil.printJson(this.response, apiPtuResult); 		      } else { 		        logger.error("请检查上传文件是否正确"); 		        result = "{\"result\", \"FAIL\",\"msg\":\"服务器开小差了\"}"; 		        PrintUtil.printJson(this.response, result); 		      } 		    } 		} }

BaseController(基类)

import java.util.Map; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.bind.annotation.ModelAttribute; /**  * 基类Controller   * 一些参数  * Title: BaseController	  * @author 小帅丶  * @version 1.0  */ public class BaseController { 	public Map session; 	public String openId; 	public String errMsg; 	public String jsonParam; 	public String callback; 	protected HttpServletRequest request; 	protected HttpServletResponse response; 	/** 	 * 每次请求都会带上 	 * @param jsonParam 	 * @param callback 	 * @param openId 	 */ 	@ModelAttribute 	public void setReqAndRes(Map session, String openId, String errMsg, 			String jsonParam, String callback, HttpServletRequest request, 			HttpServletResponse response) { 		this.session = session; 		this.openId = openId; 		this.errMsg = errMsg; 		this.jsonParam = jsonParam; 		this.callback = callback; 		this.request = request; 		this.response = response; 	} 	public Map getSession() { 		return session; 	} 	public void setSession(Map session) { 		this.session = session; 	} 	public String getOpenId() { 		return openId; 	} 	public void setOpenId(String openId) { 		this.openId = openId; 	} 	public String getErrMsg() { 		return errMsg; 	} 	public void setErrMsg(String errMsg) { 		this.errMsg = errMsg; 	} 	public String getJsonParam() { 		return jsonParam; 	} 	public void setJsonParam(String jsonParam) { 		this.jsonParam = jsonParam; 	} 	public String getCallback() { 		return callback; 	} 	public void setCallback(String callback) { 		this.callback = callback; 	} 	public HttpServletRequest getRequest() { 		return request; 	} 	public void setRequest(HttpServletRequest request) { 		this.request = request; 	} 	public HttpServletResponse getResponse() { 		return response; 	} 	public void setResponse(HttpServletResponse response) { 		this.response = response; 	} 	 	public String getRealPath(String path) { 		return request.getSession().getServletContext().getRealPath(path);  	} }

PrintUtil(响应类)

import java.io.IOException; import java.io.PrintWriter; import java.io.Writer; import javax.servlet.http.HttpServletResponse; /**  * 输出结果  * @author 小帅丶  *  */ public class PrintUtil { 	public static void printXml(HttpServletResponse response,String result){ 		try { 			response.setContentType("text/xml; charset=UTF-8");   			PrintWriter sos = response.getWriter(); 			sos.write(result); 			sos.flush(); 			sos.close(); 		} catch (IOException e) { 			// TODO Auto-generated catch block 			e.printStackTrace(); 		} 	} 	 	/** 	 * 采用json 或 jsonp 	 * @param callback 	 * @param response 	 * @param result 	 */ 	public static void printJson(String callback,HttpServletResponse response,String result){ 		boolean jsonP = false; 		if (callback != null) { 		    jsonP = true; 		    response.setContentType("text/javascript;charset=utf-8"); 		} else { 		    response.setContentType("application/x-json;charset=utf-8"); 		} 		 			try { 				Writer out = response.getWriter(); 				if (jsonP) { 				    out.write(callback + "("); 				} 				out.write(result.toString()); 				if (jsonP) { 				    out.write(");"); 				} 				out.flush(); 				out.close(); 			} catch (Exception e) { 				// TODO Auto-generated catch block 				e.printStackTrace(); 			} 			 			 	} 	 	public static void printJson(HttpServletResponse response,String result){ 		try { 			response.setCharacterEncoding("UTF-8");   		    response.setContentType("application/json; charset=utf-8");   			PrintWriter sos = response.getWriter(); 			sos.write(result); 			sos.flush(); 			sos.close(); 		} catch (IOException e) { 			// TODO Auto-generated catch block 			e.printStackTrace(); 		} 	} }
