實施例:User.java爲什麼對象在spring mvc中沒有初始化?
@Component
public class User{
public String name;
public String email;
public User() {
super();
}
public User(String name, String email) {
super();
this.name = name;
this.email = email;
}
public String getName() {
return name;
}
public String getEmail() {
return email;
}
public void setName(String name) {
this.name = name;
}
public void setEmail(String email) {
this.email = email;
}
}
HomeController.java
@Controller
public class HomeController {
@Resource
User user;
@RequestMapping(value="/getUsers", method= RequestMethod.POST)
public @ResponseBody User getUser(User user){
return user;
}
}
但是user.getName()和user.getEmail()爲空。用戶類未初始化。爲什麼?即使我在客戶端發送用戶對象,因爲
POST /spring/getUsers HTTP/1.1 Host: localhost:2015 Cache-Control: no-cache {"name":"vinod", "email":"[email protected]" }
註釋如何requestBody作品等你意識到你作爲參數傳遞的用戶返回方法,而不是自動裝配Autowired用戶,這是完全無用的?另外,如果用戶在請求正文中,作爲JSON,參數應該用'@ RequestBody'註釋 – 2015-03-02 19:46:42
您可能需要了解自動裝配工作原理和模型屬性等基本知識。 – minion 2015-03-02 19:50:58
