Serlvet中doGet()和doPost()方法(一不小心debug都用不了)
作者:互联网
eclipse开发时新建Serlvet文件会快速生成相关的方法。主要是要对doGet和doPost方法的重写。写好工程后发现没有办法得到正常的结果,同时发现自己不能debug.后来发现自己是不小心将doPost()方法中的调用doGet()的方法删除了。
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//设置编码
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
response.setContentType("text/html; charset=UTF-8");
//获取jsp页面数据
Integer no = Integer.parseInt(request.getParameter("uno"));
String name = request.getParameter("uname");
String sex = request.getParameter("usex");
Integer age =Integer.parseInt(request.getParameter("uage"));
//将数据装入一个实体类
Employee employee = new Employee(no,name,sex,age);
//调用service
EmployeeService employeeService = new EmployeeService();
boolean result = employeeService.addEmployee(employee);
PrintWriter out = response.getWriter();
if (result) {
out.println("添加成功");
}else {
out.println("添加失败,已经存在");
}
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
}
而我本身却用了
<form action="es" method="post">
所以产生了错误。
