用Spring Boot+Vue做微人事項目第十一天

用Spring Boot+Vue做微人事項目第十一天

前兩天做了微人事登錄的前端頁面和後端接口，第三天則實現了前後端接口的對接，輸入正確的用戶名和密碼之後，成功的跳轉到home頁。第四天做了Home頁的Title製作和下拉菜單，下拉菜單有三個選項，個人中心、設置和註銷登錄，還做了註銷登錄，點擊註銷登錄會出現提示：“此操作將註銷登錄，是否繼續”，點是就重新跳轉到登錄頁面，第五天做的是左邊的導航菜單，第六天是做的服務端菜單接口的設計，第七天是Vuex的介紹、安裝和配置、第八天是不寫代碼，第九天談一談前後端分離開發，權限管理的一些思路，是後端接口權限設計，第十天寫業務代碼，從系統管理的基礎信息設置開始寫，先寫前端頁面，今天開始寫系統管理的基礎信息設置的後端接口了

①：把Position實體類裏面的createdate屬性的date改成大寫的Date並修改該屬性的getter和setter方法

public class Position implements Serializable {
    private Integer id;

    /**
     * 職位
     */
    private String name;

    private Date createDate;

    private Boolean enabled;

②：把PositionMapper.xml裏面和createdate相關的全部修改成createDate

③：在controller包裏面新建system包，再在system包裏面新建basic包，再在basic包裏面創建PositionController類，在定義PositionController類的接口的時候，一定要與數據庫的menu中的url地址到一致，不然會出現沒有權限訪問的問題

@RestController
@RequestMapping("/system/basic/pos")
public class PositionController {

    @Autowired
    PositionService positionService;

    @GetMapping("/")
    public List<Position> getAllPositions(){
        return positionService.getAllPositions();
    }
   
}

PositionService類

@Service
public class PositionService {

    @Autowired
    PositionMapper positionMapper;

    public List<Position> getAllPositions() {
        return positionMapper.getAllPositions();
    }
}

PositionMapper接口

@Repository
public interface PositionMapper {
    int deleteByPrimaryKey(Integer id);

    int insert(Position record);

    int insertSelective(Position record);

    Position selectByPrimaryKey(Integer id);

    int updateByPrimaryKeySelective(Position record);

    int updateByPrimaryKey(Position record);

    List<Position> getAllPositions();
}

PositionMapper.xml

打開Postman測試查詢所有的position，效果如下圖：

再把position的增刪改三個接口也給寫一下

PositionController

@RestController
@RequestMapping("/system/basic/pos")
public class PositionController {

    @Autowired
    PositionService positionService;

    @GetMapping("/")
    public List<Position> getAllPositions(){
        return positionService.getAllPositions();
    }

    @PostMapping("/")
    public RespBean addPosition(@RequestBody Position position){
        if (positionService.addPosition(position)==1){
         return RespBean.ok("添加成功!");
        }
        return RespBean.error("添加失敗!");
    }

    @PutMapping("/")
    public RespBean updatePositions(@RequestBody Position position){
        if (positionService.updatePositions(position)==1){
            return RespBean.ok("修改成功！");
        }
        return RespBean.error("修改失敗！");

    }

    @DeleteMapping("/{id}")
    public RespBean deletePositionById(@PathVariable Integer id){
        if(positionService.deletePositionById(id)==1){
            return RespBean.ok("刪除成功!");
        }
        return RespBean.error("刪除失敗");
    }
}

PositionService

@Service
public class PositionService {

    @Autowired
    PositionMapper positionMapper;

    public List<Position> getAllPositions() {
        return positionMapper.getAllPositions();
    }

    public Integer addPosition(Position position) {
        position.setEnabled(true);
        position.setCreateDate(new Date());
        return positionMapper.insertSelective(position);
    }

    public Integer updatePositions(Position position) {
        return positionMapper.updateByPrimaryKeySelective(position);
    }

    public Integer deletePositionById(Integer id) {
        return positionMapper.deleteByPrimaryKey(id);
    }
}

PositionMapper接口和PositionMapper.xml和前面那個是一樣的，測試的添加效果如下圖所示：

測試的修改如下圖所示：

測試的刪除如下圖所示：

至此： 系統管理的基礎信息設置的後端接口已寫完
