创建同时向servlet发送文本和文件的http请求的示例

<form action="servlet-url" method="post" enctype="multipart/form-data">
  <input type="text" name="textData" placeholder="输入文本数据">
  <input type="file" name="fileData">
  <input type="submit" value="提交">
</form>

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.annotation.WebServlet;

@WebServlet("/servlet-url")
public class MyServlet extends HttpServlet {
  protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // 获取文本数据
    String textData = request.getParameter("textData");
    
    // 获取文件数据
    Part filePart = request.getPart("fileData");
    String fileName = filePart.getSubmittedFileName();
    InputStream fileContent = filePart.getInputStream();
    
    // 处理文本和文件数据
    // ...
    
    // 返回响应
    response.setContentType("text/html");
    response.getWriter().println("请求已处理");
  }
}
