Question

我正在设置一个Web应用程序，以通过JSP在DB中存储多语言数据，我试图将字符集更改为UTF-8，这是行不通的。我的表格仅在正确的配置中（nvarchar），尽管没有通过Internet获得相关示例，但我还是编程的初学者。谁能帮我解决这个问题。预先感谢
我的控制器代码：

package com.suth.DbConnectiviti;

import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


public class LoginController extends HttpServlet {

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
    String name = request.getParameter("fullname");
    String userName = request.getParameter("userName");
    String pass = request.getParameter("pass");
    String addr = request.getParameter("address");
    String age = request.getParameter("age");
    String qual = request.getParameter("qual");
    String percent = request.getParameter("percentage");
    String year = request.getParameter("yop");
    if(name.isEmpty()||addr.isEmpty()||age.isEmpty()||qual.isEmpty()||percent.isEmpty()||year.isEmpty())
    {
        RequestDispatcher rd = request.getRequestDispatcher("index.jsp");
        out.println("<font color=red>Please fill all the fields</font>");
        rd.include(request, response);
    }
    else
    {

    try {
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
     // loads driver
    Connection c = DriverManager.getConnection("jdbc:sqlserver://****;databaseName=***?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true&zeroDateTimeBehavior=convertToNull", "****", "****!");

    PreparedStatement ps = c.prepareStatement("insert into student1 values(?,?,?,?,?,?,?,?)");

    ps.setString(1, name);
    ps.setString(2, userName);
    ps.setString(3, pass);
    ps.setString(4, addr);
    ps.setInt(5, Integer.parseInt(age));
    ps.setString(6, qual);
    ps.setString(7, percent);
    ps.setString(8, year);


    ps.executeUpdate(); // execute it on test database
    System.out.println("successfuly inserted");
    ps.close();
    c.close();
    } catch (ClassNotFoundException | SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } 
    RequestDispatcher rd = request.getRequestDispatcher("error.html");
    rd.forward(request, response);
}

} }
