Java 如何在不锁定数据库的情况下向数据库中发出多个SQL查询？

我正在尝试将记录从First\u servlet.java插入到SQLite数据库中，以Second\u servlet.java。以下是我的代码：

第一个servlet.java

Second_servlet.java

每当我运行servlet时，我的日志中总是出现以下错误：

java.sql.SQLException: [SQLITE_BUSY]  The database file is locked (database is locked)
at abhishek.Details.doGet(Details.java:50)

为什么锁上了？如何解决此问题？

嗨，检查可能会有帮助。嗨，检查可能会有帮助。

public class Second_servlet extends HttpServlet {
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        Cookie[] ck=request.getCookies();
        PrintWriter pw=response.getWriter();
    try {
           Class.forName("org.sqlite.JDBC");
           Connection c=DriverManager.getConnection("jdbc:sqlite:D:\\storage.db");
           if (c!=null) {
               System.out.println("Database created successfully");
               Statement st=c.createStatement();
               st.execute("CREATE TABLE IF NOT EXISTS Details ( ID INTEGER PRIMARY KEY AUTOINCREMENT, NAME VARCHAR(30), EMAIL VARCHAR(30), AGE INTEGER)");
               PreparedStatement p=c.prepareStatement("INSERT INTO Details(ID,NAME,EMAIL,AGE) VALUES(?,?,?,?)");
               if (ck==null) 
                    pw.println("No cookies found");
                else {
                    for(Cookie cookie: ck) {
                        if(cookie.getName().equals("name")) {

                            p.setString(2,cookie.getValue());

    } catch (ClassNotFoundException | SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
