String Pass = request.getParameter("password");Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://127.0.0.1:7777/ding","root","123456");
//Statement stm = conn.createStatement();
//ResultSet rs = stm.executeQuery("select * from tuceng where username ="+"."+User+".");
try{
PreparedStatement pstm = conn.prepareStatement("insert into tuceng (username,password) values (?,?)");
pstm.setString(1,User);
pstm.setString(2,Pass);}catch(SQLException e) {
System.out.println("数据没有插入上");
out.println(e);

con.setAutoCommit(false);// 更改JDBC事务的默认提交方式 pstm. excuteUpdate()con.commit();//提交JDBC事务
con.setAutoCommit(true);// 恢复JDBC事务的默认提交方式
con.close()
拼完sql的参数之后添加执行。
pstm.execute(); 返回影响的行数列、
加上代码后调试下是否可以？是否有执行到这段代码。
