java - 使用 Servlet 写入文本文件

Question

如何使用 Servlet 在 HTML 页面上设置三个文本字段并将输入的数据存储在服务器上的文本文件中？

Answer 1

1. Create a form in the HTML page and have the action set to the name of the Servlet.
2. Within that Servlet, call the parameters with request.getParameter("...");

3. Append the combined String to the file using something like:

   PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter("FileName", true))); out.println(createFullNameString(firstName, middleName, lastName)); out.close();

Answer 2

    <input type="text" name="firstname" id="firstname" />
 <input type="text" name="middlename" id="middlename" />
 <input type="text" name="lastname" id="lastname" />

    in servlet

    String firstname=request.getParameter("firstname");
String middlename=request.getParameter("middlename");
String lastname=request.getParameter("lastname");
