@Controller：修饰class，用来创建处理http请求的对象@RestController：Spring4之后加入的注解，原来在@Controller中返回json需要@ResponseBody来配合，如果直接用@RestController替代@Controller就不需要再配置@ResponseBody，默认返回json格式。@RequestMapping：配置url映射| 请求类型 | URL | 功能说明 |
|---|---|---|
| GET | /users | 查询用户列表 |
| POST | /users | 创建一个用户 |
| GET | /users/id | 根据id查询一个用户 |
| PUT | /users/id | 根据id更新一个用户 |
| DELETE | /users/id |
|
User实体定义：
private Long id; private String name; private Integer age; // 省略setter和getter
User restful接口声明
@RequestMapping(value = "/users") public interface UserRestService { @RequestMapping(value = "/", method = RequestMethod.GET) List<User> getUserList(); @RequestMapping(value = "/", method = RequestMethod.POST) String postUser(@ModelAttribute User user); @RequestMapping(value = "/{id}", method = RequestMethod.GET) User getUser(@PathVariable Long id); @RequestMapping(value="/{id}", method=RequestMethod.PUT) String putUser(@PathVariable Long id, @ModelAttribute User user); @RequestMapping(value="/{id}", method=RequestMethod.DELETE) String deleteUser(@PathVariable Long id); }
接口实现
@RestController public class UserRestServiceImpl implements UserRestService { static Map<Long, User> users = Collections.synchronizedMap(new HashMap<Long, User>()); @Override public List<User> getUserList() { List<User> r = new ArrayList<User>(users.values()); return r; } @Override public String postUser(@ModelAttribute User user) { users.put(user.getId(), user); return "success"; } @Override public User getUser(@PathVariable Long id) { return users.get(id); } @Override public String putUser(@PathVariable Long id, @ModelAttribute User user) { User u = users.get(id); u.setName(user.getName()); u.setAge(user.getAge()); users.put(id, u); return "success"; } @Override public String deleteUser(@PathVariable Long id) { users.remove(id); return "success"; } }
验证：
以创建用户为例
