Spring Boot - 构建RESTful API与单元测试

为什么80%的码农都做不了架构师？>>>   

原文

@Controller 标记该 class为处理http请求的对象

@RestController Spring4后加入的注解,原来@Controller中返回 json需要返回@ResponseBody。使用@RestController不需要配置,自动默认返回 json。

RESTful api设计：

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查询用户
PUT	/users/id	根据 id更新用户
DELETE	/users/id	根据 id删除用户

 

@RestController
@RequestMapping("/users")
public class UserController {

    //创建线程安全的 map
    static Map users = Collections.synchronizedMap(new HashMap());

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public List getUserList() {
        ArrayList users = new ArrayList(UserController.users.values());
        return users;
    }

    @RequestMapping(value = "/", method = RequestMethod.POST)
    public String postUser(@ModelAttribute User user) {
        users.put(user.getId(), user);
        return "success";
    }

    @RequestMapping(value = "/{id}", method = RequestMethod.GET)
    public User getUser(@PathVariable Long id) {
        return users.get(id);
    }

    @RequestMapping(value = "/{id}", method = RequestMethod.PUT)
    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";
    }

    @RequestMapping(value = "/{id}", method = RequestMethod.DELETE)
    public String deleteUser(@PathVariable Long id) {
        users.remove(id);
        return "success";
    }
}
