之前实现的动态表单的启动功能，现在把审核功能也做个总结。
审核流程界面 最终效果图：
主要需要实现的是一下功能点：
1. 列表页面
1.1.待办任务页面。列表中显示当前用户可以处理的流程。
1.2.运行中的流程。列表中显示当前用户 待办 或者 参与过并且未结束 的流程。
1.3.已结束的流程。列表中显示当前用户 参与过并且已结束 的流程。
2.审核页面
2.1 审核列表。 显示流程审核节点的流程中相关审核情况。根据是是待办人决定是否显示 审核操作里的 【通过】 【退回】等按钮。非待办人不能操作流程。
2.2 具体业务的动态表单。根据节点配置的表单属性配置显示动态表单。类是启动流程功能里的start节点配置。同一流程实例不同审核人可以根据配置的不同显示不同的业务表单。如上面图片中的任务分配节点可以配置一个任务分配的下拉框。这个下拉框控件只在任务分配节点显示，其他节点则不会显示。
待办任务页面点击任务连接进入审核页面具体实现：
ProcInstController.java
/** * 审核流程页面 */ @RequestMapping(value = "index") public String index(Model model,String pid,RedirectAttributes attr) { String pageUrl = ""; ProcInst pi = procInstService.getEntityById(pid); //动态表单,外置表单,普通表单(普通表单使用c_前缀，外置表单使用ex_前缀，其他的是动态表单)。参考procDefList.jsp页面 ProcDef pd = procDefService.getEntityById(pi.getProcDefId()); pi.setProcDef(pd); if(pd.getKey().indexOf("c_") == 0){//普通表单 }else if(pd.getKey().indexOf("ex_") == 0){//外置表单 //外置表单, 与动态表单不同的是根据表单key获取事先定义好的表单，不需要系统自动生成。 }else { //动态表单 List<FormAttr> formAttrlist = procInstService.getFormAttrList(pi); model.addAttribute("pi", pi); model.addAttribute("formAttrlist", formAttrlist); //审核流程列表 List<TaskInst> tasks = taskInstService.getTaskList(pi.getId()); model.addAttribute("tasks",tasks); model.addAttribute("tasksSize",tasks.size()); //流程变量 List<HistoricVariableInstance> varList = historyService.createHistoricVariableInstanceQuery().processInstanceId(pi.getId()).list(); Map<String,Object> varMap = new HashMap<String,Object>(); for (HistoricVariableInstance variableInstance : varList) { varMap.put(variableInstance.getVariableName(), variableInstance.getValue()); } model.addAttribute("varMap",varMap); pageUrl = "/system/workflow/hi/reviewed"; } return pageUrl; }reviewed.jsp

//动态表单List<FormAttr> formAttrlist = procInstService.getFormAttrList(pi);public List<FormAttr> getFormAttrList(ProcInst pi) { List<FormAttr> formMap = new ArrayList<FormAttr>(); ByteArray ba = pi.getProcDef().getByteArray(); String xml = null; try { xml = new String(ba.getBytes(), "utf-8"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } Node root = XMLTools.Dom2Map(xml); Node processNode = root.getSubNodeByName("process"); //获取当前流程待执行的结点 String actId = getLastActId(pi.getId()); List<Node> list = processNode.getChildrenList(); Node lastNode = null; for (Node node : list) { if(actId.equals(node.getAttrMap().get("id"))){ lastNode = node; } } Node extensionElements = lastNode.getSubNodeByName("extensionElements"); if(extensionElements != null){ List<Node> formPropertyList = extensionElements.getChildrenList(); for (Node formProperty : formPropertyList) { FormAttr fa = new FormAttr(formProperty); formMap.add(fa); } } return formMap; }
2.获取当前实例的流程变量，然后对 业务表单 进行初始化赋值。
//流程变量 List<HistoricVariableInstance> varList = historyService.createHistoricVariableInstanceQuery().processInstanceId(pi.getId()).list(); Map<String,Object> varMap = new HashMap<String,Object>(); for (HistoricVariableInstance variableInstance : varList) { varMap.put(variableInstance.getVariableName(), variableInstance.getValue()); } model.addAttribute("varMap",varMap);3.审核列表。比较复杂的和关键的一个逻辑功能模块，暂时先只考虑常用的情景。
List<TaskInst> tasks = taskInstService.getTaskList(pi.getId());public List<TaskInst> getTaskList(String pid) { List<TaskInst> tasks = taskInstDao.getTaskList(pid); int size = tasks.size(); TaskInst lastTaskInst = tasks.get(size-1); Account curAccount = AccountShiroUtil.getCurrentUser(); if(lastTaskInst.getEndTime() == null){ List<Account> candidateUsers = null; if(lastTaskInst.getAssignee() != null && !lastTaskInst.getAssignee().equals("")){ //任务已签收，不用管配置的候选用户了,可以看做只有签收人一个候选用户 Account account = new Account(); account.setAccountId(lastTaskInst.getAssignee()); candidateUsers = accountDao.find(account); //这个可能size=0，表示配置的Assignee值可能不在用户表里 if(candidateUsers.size() == 0){ lastTaskInst.setAssignee(null); } } if(lastTaskInst.getAssignee() == null || lastTaskInst.getAssignee().equals("")){ //通过流程配置的候选用户和候选组获取所有候选用户 candidateUsers = taskInstDao.getCandidateUsers(lastTaskInst.getId()); } lastTaskInst.setCandidateUsers(candidateUsers); //判断当前用户是否在候选用户里，在则把当前用户移除,并且将最后一个任务指派人改为当前用户（没有考虑已签收，但还没有处理的情况） for (int i = 0; i < candidateUsers.size(); i++) { if(curAccount.getAccountId().equals(candidateUsers.get(i).getAccountId())){ Account account = candidateUsers.remove(i); lastTaskInst.setIsCurAccount(1); lastTaskInst.setAssignee(account.getAccountId()); lastTaskInst.setAssigneeName(account.getName()); break; } } } //第一行添加发起流程任务 TaskInst tk = taskInstDao.getStartProcTask(pid); tasks.add(0, tk); return tasks; }
4.相关的一些dao层sql
procInstService.getEntityById(pid)
