@RestController 用于返回对象，会自动格式化为JSON
@RequestMapping("/user2")
public User2 user2(Model model){
model.addAttribute("content", hello + "（第二种）");
User2 user=new User2();
user.setId(1);
user.setName("tomas");
user.setPwd("pwd");
return user;
}
@Control会默认返回jsp页面
想返回对象的话还需要加上@ResponseBody注解
@RequestMapping("/user2")
@ResponseBody
public User2 user2(Model model){
model.addAttribute("content", hello + "（第二种）");
User2 user=new User2();
user.setId(1);
user.setName("tomas");
user.setPwd("pwd");
return user;
}
返回结果一致:
{
- id: 1,
- name: "tomas",
- pwd: "pwd"
}
