接上一個
開發(fā)多級審批流程


設計約束
每一個請假單對應一個審批流程
請假單創(chuàng)建后,按業(yè)務規(guī)則生成部門經(jīng)理、總經(jīng)理審批任務
審批任務的經(jīng)辦人只能審批自己轄區(qū)內的請假申請
所有審批任務"通過",代表請假已經(jīng)批準
任意審批任務"駁回"操作,其余審批任務取消,請假申請被駁回
請假流程中任意節(jié)點產(chǎn)生的操作都要生成對應的系統(tǒng)通知

請假申請表


請假流程表


請假通知表


相關的實體類都進行創(chuàng)建

請假單接口的創(chuàng)建

public interface LeaveFormDao {public void insert(LeaveForm form);public List<Map> selectByParams(@Param("pf_state") String pfState,@Param("pf_operator_id") Long operatorId); } <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <!--namespace與包名一致--> <mapper namespace="com.imooc.oa.dao.LeaveFormDao"><!--id與方法名對應parameterType與方法參數(shù)類型對應resultType與方法返回類型對應--><insert id="insert" parameterType="com.imooc.oa.entity.LeaveForm"useGeneratedKeys="true" keyProperty="formId" keyColumn="form_id">INSERT INTO adm_leave_form(employee_id, form_type, start_time, end_time,reason, create_time, state)VALUES (#{employeeId}, #{formType}, #{startTime}, #{endTime},#{reason}, #{createTime}, #{state})</insert> </mapper>

在配置文件中進行注冊
剩下兩個表的操作都一樣

創(chuàng)建一個動態(tài)SQL根據(jù)傳入的員工獲取對應的上級主管對象

前端代碼就不列出來了。

為了解決頁面顯示問題

@WebServlet(name = "ForwardServlet", urlPatterns = "/forward/*") public class ForwardServlet extends HttpServlet {@Overrideprotected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException,IOException {String uri = request.getRequestURI();/** /forward/form* /forward/a/b/c/form*/String subUri = uri.substring(1);String page = subUri.substring(subUri.indexOf("/"));request.getRequestDispatcher(page + ".ftl").forward(request, response);} }

請假審批功能
首先查詢自己要審批的表單條件是，審批人為自己和審批狀態(tài)為processing(正在處理)

<select id="selectByParams" parameterType="java.util.Map" resultType="java.util.Map">select f.*, e.name, d.*from adm_leave_form f,adm_process_flow pf,adm_employee e,adm_department dwhere f.form_id = pf.form_idand pf.state = #{pf_state}and pf.operator_id = #{pf_operator_id}and f.employee_id = e.employee_idand e.department_id = d.department_id</select> public List<Map> getLeaveFormList(String pfState, Long operatorId) {return (List<Map>) MybatisUtils.executeQuery(sqlSession -> {LeaveFormDao dao = sqlSession.getMapper(LeaveFormDao.class);List<Map> formList = dao.selectByParams(pfState, operatorId);//狀態(tài)、經(jīng)辦人編號return formList;});} /*** 查詢需要審核的請假單列表*/public void getLeaveFormList(HttpServletRequest request, HttpServletResponse response) throws ServletException,IOException {User user = (User) request.getSession().getAttribute("login_user");List<Map> formList = leaveFormService.getLeaveFormList("process", user.getEmployeeId());//當前登錄的員工編號Map result = new HashMap();result.put("code", "0");result.put("msg", "");result.put("count", formList.size());result.put("data", formList);String json = JSON.toJSONString(result);response.getWriter().println(json);}

審批業(yè)務邏輯
情況1：普通員工請假，小于72小時，部門經(jīng)理審批
情況2：普通員工請假，大于72小時，部門經(jīng)理審批通過，總經(jīng)理需要再次審批
情況3：普通員工請假，大于72小時，部門經(jīng)理審批未通過，總經(jīng)理不用審批
情況4：部門經(jīng)理請假，總經(jīng)理審批
情況5：總經(jīng)理請假，直接通過
