package com.yunst.demo.controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.yunst.demo.domain.User;
@RestController
@RequestMapping("/user")
public class UserController {
@RequestMapping("/{id}")
public User view(@PathVariable("id") Long id) {
User user = new User();
user.setId(id);
user.setName("張三丰");
user.setAge(26);
user.setSex('男');
user.setAddress("湖北省武當山");
return user;
}
}
3：編寫實體類user
