用戶模塊User

在這里插入圖片描述

1. export_domain子工程User用戶（員工）類

//用戶表
public class User {
    private String userId;
    //所在部門
    private String deptId;
    private String email;
    private String userName;
    private String station;
    private String password;
    private long state;
    private String companyId;
    private String companyName;
    private String deptName;
    private String managerId;
    private String gender;
    private String telephone;
    private String birthday;
    private int degree;
    private double salary;
    private String joinDate;
    private long orderNo;
    private String createBy;
    private String createDempt;
    private Date createTime;
    private String updateBy;
    private Date updateTime;
    private String remark;
}

2. export_system_service子工程撰寫測驗類測驗用戶的CRUD

TestUserService

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath*:spring/applicationContext-*.xml")
public class TestUserService {
    //記錄日志
    private static final Logger l = LoggerFactory.getLogger(TestUserService.class);


    @Autowired
    IUserService iUserService;

    //測驗通過公司id查詢所有公司用戶，分頁顯示
    @Test
    public void test01(){
        String companyId="1";
        //作為一個公司用戶的管理員，只能查自己公司的員工，分頁顯示當前第一頁，每頁3條資料
        PageInfo<User>  pi= iUserService.findByPage(1,3,companyId);
        l.info("pi = "+pi);
    }

    //測驗新增一個用戶
    @Test
    public void test02(){
        User user = new User();
        user.setUserName("新增用戶addUser");
        user.setDeptId(UUID.randomUUID().toString());
        user.setDeptId("1");
        user.setCompanyId("1");
        iUserService.saveUser(user);
        l.info("增加User  ---  : " + user);
    }

    //更新用戶資訊
    @Test
    public void test03(){
        String userId="899676f8-9de7-4ae0-93f3-61869dc9fedb";
        User user =  iUserService.findUserById(userId);
        l.info("test03 更新 user = "+user);
        //修改
        user.setUserName("update User 更新");
        //保存
        iUserService.updateUser(user);
    }

    //測驗洗掉
    @Test
    public void test04(){
        //
        //洗掉業務，就是根據指定的id，洗掉資料庫中的記錄
        String userId="899676f8-9de7-4ae0-93f3-61869dc9fedb";
        //洗掉
        boolean flag = iUserService.deleteUser(userId);
        l.info(flag+"");

    }

    //通過公司查找所有的用戶（員工）
    @Test
    public void test05(){
        //A公司管理員，只能查A公司用戶或者員工
        String companyId="1";
        List<User> list = iUserService.findAllUsers(companyId);
        l.info("公司的所有userList = "+list);
    }
}

3. export_system_service子工程的service介面和實作類

IUserService

//user業務介面
public interface IUserService {
    //分頁顯示用戶資訊
    PageInfo<User> findByPage(int curr, int pageSize, String companyId);

    void saveUser(User user);

    User findUserById(String userId);

    void updateUser(User user);

    boolean deleteUser(String userId);

    List<User> findAllUsers(String companyId);
}

UserServiceImpl

@Service
public class UserServiceImpl implements IUserService {

    @Autowired
    IUserDao iUserDao;

    @Override
    public PageInfo<User> findByPage(int curr, int pageSize, String companyId) {
        //設定分頁引數
        PageHelper.startPage(curr,pageSize);
        //呼叫全查，查找所有的用戶（根據公司id）
        List<User> list = iUserDao.findAll(companyId);
        //包裝成PageInfo
        PageInfo<User> pi = new PageInfo<>(list);
        return pi;
    }

    @Override
    public User findUserById(String userId) {
        return iUserDao.findById(userId);
    }

    @Override
    public boolean deleteUser(String userId) {
        iUserDao.deleteById(userId);
        return true;
    }

    @Override
    public List<User> findAllUsers(String companyId) {
        return iUserDao.findAll(companyId);
    }

    @Override
    public void saveUser(User user) {
        String uuid= UUID.randomUUID().toString();
        user.setUserId(uuid);
        iUserDao.save(user);
    }
    @Override
    public void updateUser(User user) {
        iUserDao.update(user);
    }
}

4. export_dao子工程寫dao介面及其映射

IUserDao

public interface IUserDao {
    //根據公司id，查找所有用戶，按照更新時間排序
    List<User> findAll(String companyId);
    //添加新增一個user
    void save(User user);
    //通過id查找用戶
    User findById(String userId);
    //更新user資訊
    void update(User user);
    //通過id洗掉user
    void deleteById(String userId);
}

IUserDao.xml

5. export_web_manager子工程撰寫controller

UserController

@Controller
@RequestMapping("/system/user")
public class UserController extends BaseController {
    private static  final Logger l = LoggerFactory.getLogger(UserController.class);

    @Autowired
    IUserService iUserService;
    @Autowired
    IDeptService iDeptService;

    @RequestMapping(path="/toList",method ={ RequestMethod.GET, RequestMethod.POST})
    public String toList(@RequestParam(defaultValue = "1") int curr, @RequestParam(defaultValue = "10")int pageSize){
        //調查詢分頁串列的方法
        PageInfo<User> pi = iUserService.findByPage(curr, pageSize,getLoginCompanyId());
        //將pi分頁資訊發送到jsp頁面
        request.setAttribute("pi",pi);
        return "system/user/user-list";
    }


    //  洗掉用戶
    @RequestMapping(path="/delete",method ={ RequestMethod.GET, RequestMethod.POST})
    @ResponseBody
    public Object delete(String userId){//引數接收頁面js提交過來的userId
        boolean flag = iUserService.deleteUser(userId);
        if(flag){
            return Msg.init(200,"洗掉成功",null);
        }else{
            return Msg.init(-200,"洗掉失敗",null);
        }
    }

    //增加頁面
    @RequestMapping(path="/toAdd",method ={ RequestMethod.GET, RequestMethod.POST})
    public String toAdd(){
        //頁面上有一個下拉選單 ，需要查詢所有的部門
        List<Dept> depts = iDeptService.findAll(getLoginCompanyId());
        //添加到request
        request.setAttribute("depts",depts);
        return "system/user/user-add";
    }

    //添加用戶
    @RequestMapping(path="/add",method ={ RequestMethod.GET, RequestMethod.POST})
    public String add(User user){//接收頁面提交過來的表單資料
        l.info("add user="+user);

        //用戶或者員工屬于一家公司，所以公司companyId是必須的
        user.setCompanyId(getLoginCompanyId());
        user.setCompanyName(getLoginCompanyName());

        l.info("add user="+user);

        iUserService.saveUser(user);

        return "redirect:/system/user/toList";
    }

    //更新回顯
    @RequestMapping(path="/toUpdate",method ={ RequestMethod.GET, RequestMethod.POST})
    public String toUpdate(String userId){//需要使用引數接收提交的 userId
        l.info("toUpdate userId="+userId);
        //需要根據userId查詢當前模塊的記錄，回顯

        User user =  iUserService.findUserById(userId);
        l.info("toUpdate user="+user);
        request.setAttribute("user",user);
        //頁面上有一個下拉選單 ，需要查詢所有的部門
        List<Dept> depts = iDeptService.findAll(getLoginCompanyId());
        //添加到request
        request.setAttribute("depts",depts);
        return "system/user/user-update";
    }

    //更新用戶
    @RequestMapping(path = "/update", method = {RequestMethod.GET, RequestMethod.POST})
    public String update(User user) {//需要接收編輯頁面提交的表單資料
        l.info("update user=" + user);
        //更新
        iUserService.updateUser(user);
        return "redirect:/system/user/toList";
    }


}

6. export_web_manager子工程撰寫jsp頁面

user-add.jsp添加（下拉選單選中的部門提交后沒有名稱）

    <div class="col-md-4 data">
        <input type="hidden" id="deptName" name="deptName" value="${depts[0].deptName}" >
        <script type="text/javascript">
            function selectDepartment() {
                     //獲取選中值的中文
                       var select= $('#select option:selected')
                      //將中文賦值給隱藏的輸入框，最后提交到后臺
                      //alert(select.val())
                      //alert(select.html())
                      $('#deptName').val(select.html())
            }
    
        </script>
        <select id="select" class="form-control" onchange="selectDepartment()" name="deptId">
            <c:forEach items="${depts}" var="item">
                <option value="${item.deptId}">${item.deptName}</option>
            </c:forEach>
        </select>
    </div>

更新user-update.jsp的時候對于不需要更新的欄位（但是欄位必須）要設定隱藏域來向后臺提交，

<div class="col-md-4 data">
    <input type="hidden" id="userId" name="userId" value="${user.userId}">
    <input type="hidden" id="deptId" name="deptId" value="${user.deptId}">
    <input type="hidden" id="deptName" name="deptName" value="${user.deptName}">
    <input type="hidden" id="companyId" name="companyId" value="${user.companyId}">
    <input type="hidden" id="companyName" name="companyName" value="${user.companyName}">
    <script type="text/javascript">
        function selectDepartment() {
            //獲取選中值的中文
            var select= $('#select option:selected')
            //將中文賦值給隱藏的輸入框，最后提交到后臺
            //alert(select.val())
            //alert(select.html())
            $('#deptName').val(select.html())
            $('#deptId').val(select.val())
        }

    </script>
    <select id="select" class="form-control" onchange="selectDepartment()"  >
        <c:forEach items="${depts}" var="item">
            <option
                    <%--當前用戶的deptId與查詢的部門集合中的元素的deptId相等，則應該選中--%>
                    <c:if test="${user.deptId==item.deptId}" >
                        selected
                    </c:if>
                    value="${item.deptId}">${item.deptName}</option>
        </c:forEach>
    </select>
</div>
