記錄一個報錯資訊：
在使用Mybatis-plus時，測試查詢單個數據時一直報錯

測試類

@Test
    public void test(){
        AdminRole adminRole = adminRoleMapper.selectOne(Wrappers.<AdminRole>lambdaQuery().eq(AdminRole::getId, 1));
        System.out.println("adminRole = " + adminRole);
    }

pojo

@Data
@AllArgsConstructor
@NoArgsConstructor
public class AdminRole extends BasePojo {

    private Long id;
    private String name;
    private String desc;//角色的描述
    private Boolean state;// 角色的狀態，1啟用，2停用

}

MySQL欄位

後來查詢到是資料庫欄位名稱有關鍵字，desc。導致無法對映到pojo封裝回去，更改desc欄位後恢復。
