改了你的部分代码，自己添加了数据库表，我这边可以显示。
controller控制器代码
public class TestController implements Controller {
@Override
public ModelAndView handleRequest(HttpServletRequest req, HttpServletResponse resp) {
//参数通过request获取，请求http://localhost:8080/xx/test?phoneNumber=18888888888
String phoneNumber = req.getParameter("phoneNumber");
ModelAndView modelAndView = new ModelAndView();
Connection conn;
//链接数据库，查询数据，设值
try {
Class.forName("com.mysql.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "123456");
String strSql = "select * from mobile where number=?" ;
PreparedStatement ps = conn.prepareStatement(strSql);
ps.setString(1, phoneNumber);
ResultSet result = ps.executeQuery();
while(result.next()){
System.out.println(result.getString("number"));
modelAndView.addObject("ee", result.getString("code"));
System.out.println(result.getString("code"));
}
conn.close();
} catch (SQLException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
//spring mvc 的jsp路径
modelAndView.setViewName("task/hello");
return modelAndView;
}
}
我要提问
