我是新來的。春天也是新的。我想用spring和hibernate插入數據到數據庫中
我想使用spring和hibernate將數據插入到我的數據庫中。你能告訴我我的代碼有什麼問題嗎？
//this is my bean class!!!!!!!!!
package com.bean;
public class FormBean {
private String name;
private String email;
private String contact;
private String address;
private String gender;
private String items;
/*public FormBean(String name, String email, String contact, String address,
String gender, String items) {
super();
this.name = name;
this.email = email;
this.contact = contact;
this.address = address;
this.gender = gender;
this.items = items;
}*/
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getContact() {
return contact;
}
public void setContact(String contact) {
this.contact = contact;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getItems() {
return items;
}
public void setItems(String items) {
this.items = items;
}
}
這裏是我的控制器類，我無法在控制器類中創建dao對象。 如何調用dao類將數據導入數據庫。

FormBeanDAO formbeandao;
/*@RequestMapping("/hello")

return new ModelAndView("hello","message", message);
}*/
/*@RequestMapping(value="/page1", method=RequestMethod.GET)
public ModelAndView page1(){
String msg="main jsp page";
System.out.println(msg);
return new ModelAndView("","command",new FormBean());
}*/
@RequestMapping(value = "/page1", method = RequestMethod.POST)
public String addformdetails(@ModelAttribute("page1")FormBean form, ModelMap model){
model.addAttribute("name", form.getName());
model.addAttribute("email", form.getEmail());
model.addAttribute("contact", form.getContact());
model.addAttribute("address", form.getAddress());
model.addAttribute("gender", form.getGender());
model.addAttribute("items", form.getItems());
System.out.println(form.getName()+" "+form.getEmail()+" "+form.getContact()+" "+form.getAddress()+" "+form.getGender()+" "+form.getItems());
//formbeandao.
return "userinput";
}
/*@RequestMapping(value="/save",method = RequestMethod.POST)
