httpclient中文乱码问题

HttpClient httpclient = HttpClientBuilder.create().build();

HttpPost httppost = new HttpPost(“http://localhost:8080/servlet/UploadServlet”); 
MultipartEntityBuilder builder = MultipartEntityBuilder.create();

builder.setCharset(Charset.forName("UTF-8"));//设置请求的编码格式

builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);//设置浏览器兼容模式

builder.addTextBody("projectNo", "dfdsfd");

ContentType contentType = ContentType.create("text/plain",Charset.forName("UTF-8"));//解决中文乱码

builder.addTextBody("project", "我看看",contentType);

builder.addBinaryBody("file1",new File("C:/截图.png") );//增加附件，第二个参数可以是File,byte[],InputStream，中文文件名也可以

httppost.setEntity(builder.build());

HttpResponse response = httpclient.execute(httppost);

备注：多数解决方案是不使用addTextBody而使用addPart与StringBody，但StringBody已不建议使用。
