[Day 5]新手村外的首战是史莱姆应该是定番吧(後端篇)

今天我们实作Users的CRUD，但今天因为花很多时间在前端的Header的排版，所以没有什麽时间可以细作Users，
我们先根据Native Camp的会员页和注册页来看大概需要什麽栏位後暂时先宣告好我们的schema。
Users.java 题外话lombok很好用，省了很多工

package com.mock.nativecamp.model;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection = "Users")
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Users {
    @Id
    private String id;
    private String name;
    private String email;
    private String password;
    private String status;
    private String coin;
    private String timezone;
    private String payMethod;
    private String nextPayCheck;
    private String ssoId;
}

然後就可以开始撰写我们的controller和service了，controller主要是定义API接口，service则是做逻辑处理和Repository CRUD的呼叫。
由於时间关系我只做到Create User和Get all Users和Get one User。
UsersController.java

package com.mock.nativecamp.controller;

import com.mock.nativecamp.model.Users;
import com.mock.nativecamp.service.UsersService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.*;

@Slf4j
@RestController
@RequestMapping("/users")
public class UsersController {

    private final UsersService usersService;

    public UsersController(UsersService usersService) {
        this.usersService = usersService;
    }

    /**
     * Signup user
     * @param user
     * @return AdminUser
     * @throws Exception
     */
    @PostMapping(path = "/signup", consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
    public Object SignupUser(@RequestBody Users user) throws Exception {
        return usersService.signupUser(user);
    }

    /**
     * Get all Users
     * @return Users list
     * @throws Exception
     */
    @GetMapping(path = "/all", produces = MediaType.APPLICATION_JSON_VALUE)
    public Object GetAllUsers() throws Exception {
        return usersService.getAllUsers();
    }

    /**
     * Get one user
     * @return Users
     * @throws Exception
     */
    @GetMapping(path = "/user", produces = MediaType.APPLICATION_JSON_VALUE)
    public Object GetUsers(@RequestParam String id) throws Exception {
        return usersService.getUser(id);
    }

}

因为只是简单的测试是否可以操作存取MongoDB，尚未做逻辑检查。
UsersService.java

package com.mock.nativecamp.service;

import com.mock.nativecamp.model.Users;
import com.mock.nativecamp.repository.UsersRepository;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Service;

@Slf4j
@Service
public class UsersService {

    @Autowired
    private UsersRepository usersRepository;

    public Object signupUser(Users user) {
        usersRepository.save(user);
        return new ResponseEntity(HttpStatus.ACCEPTED);
    }

    public Object getAllUsers() {
        return usersRepository.findAll();
    }

    public Object getUser(String id) {
        return usersRepository.findById(id);
    }
}

然後运行起来使用postman来测试
新增使用者
