javaee三大框架整合宅急送项目lib包

二、完善其余功能节点 -- 流程 1、 将 提供其余节点页面 复制 pages/zhongzhuan 入库（点击左侧菜单入库） ----- Action （查询入库任务列表）---- instore_list.jsp ---- 办理任务 ---- instore_complete.jsp（提交form） --- Action （办理任务流转到下一个节点） 修改function 数据表 入库 task_findInStoreTask.action 出库 task_findOutStoreTask.action 签收 task_findReceiveInfoTask.action 2、 查询任务列表 TaskAction // 业务方法 ----- 查询入库环节 的个人任务 public String findInStoreTask(){ // 登陆用户 User user = (User) getSession().getAttribute("user"); List<ZhongZhuanInfo> zhongZhuanInfoList = myTaskService.findTransferTask(user,"入库"); // 值栈 ActionContext.getContext().put("zhongZhuanInfoList", zhongZhuanInfoList); return "findInStoreTaskSUCCESS"; } // 业务方法 ----- 查询出库环节 的个人任务 public String findOutStoreTask(){ // 登陆用户 User user = (User) getSession().getAttribute("user"); List<ZhongZhuanInfo> zhongZhuanInfoList = myTaskService.findTransferTask(user,"出库"); // 值栈 ActionContext.getContext().put("zhongZhuanInfoList", zhongZhuanInfoList); return "findOutStoreTaskSUCCESS"; } // 业务方法 ----- 查询签收环节 的个人任务 public String findReceiveInfoTask(){ // 登陆用户 User user = (User) getSession().getAttribute("user"); List<ZhongZhuanInfo> zhongZhuanInfoList = myTaskService.findTransferTask(user,"配送签收"); // 值栈 ActionContext.getContext().put("zhongZhuanInfoList", zhongZhuanInfoList); return "findReceiveInfoTaskSUCCESS"; } 3、 配置struts.xml结果页面 <result name="findInStoreTaskSUCCESS">/WEB-INF/pages/zhongzhuan/instore_list.jsp</result> <result name="findOutStoreTaskSUCCESS">/WEB-INF/pages/zhongzhuan/outstore_list.jsp</result> <result name="findReceiveInfoTaskSUCCESS">/WEB-INF/pages/zhongzhuan/receiveinfo_list.jsp</result> 4、 Action办理对应节点任务 // 业务方法 ---- 办理入库任务 public String instorecomplete(){ InStore inStore = new InStore(); inStore.setInfo(info); inStore.setUpdateTime(new Date()); // 调用业务层 myTaskService.completeInStore(taskId, inStore); return "instorecompleteSUCCESS"; } // 业务方法 ---- 办理出库任务 public String outstorecomplete(){ OutStore outStore = new OutStore(); outStore.setInfo(info); outStore.setUpdateTime(new Date()); // 调用业务层 myTaskService.completeOutStore(taskId, outStore); return "outstorecompleteSUCCESS"; } // 业务方法 ---- 办理签收任务 public String receiveinfocomplete(){ ReceiveGoodsInfo receiveGoodsInfo = new ReceiveGoodsInfo(); receiveGoodsInfo.setInfo(info); receiveGoodsInfo.setUpdateTime(new Date()); // 调用业务层 myTaskService.completeReceiveGoodsInfo(taskId, receiveGoodsInfo); return "receiveinfocompleteSUCCESS"; } 5、 struts.xml 跳转回任务列表 <result name="instorecompleteSUCCESS" type="redirectAction">task_findInStoreTask</result> <result name="outstorecompleteSUCCESS" type="redirectAction">task_findOutStoreTask</result> <result name="receiveinfocompleteSUCCESS" type="redirectAction">task_findReceiveInfoTask</result> 在JBPM在流程结束时，发生异常 org.springframework.dao.DataIntegrityViolationException: could not delete: [org.jbpm.pvm.internal.model.ExecutionImpl#50001]; SQL [delete from JBPM4_EXECUTION where DBID_=? and DBVERSION_=?]; constraint [null]; nested exception is org.hibernate.exception.ConstraintViolationException: could not delete: [org.jbpm.pvm.internal.model.ExecutionImpl#50001] 解决： hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect ======================================================================================================================== 三、 流程实例 查看管理 1、 查询实例功能 查询系统正在运行实例 ExecutionService.createProcessInstanceQuery() 查询系统已经完成的实例 HistoryService.createHistoryProcessInstanceQuery() json/admin/json { id:1005, pId:100, name:"查看正在运行的任务", t:"",page:"page_workflow_processinstance.action"} 改为 { id:1005, pId:100, name:"查看正在运行的任务", t:"",page:"processinstance_list.action"} 2、 每个运行流程实例，关联流程变量 ZhongZhuanInfo 包含所有流程信息 根据流程实例id 查询ZhongZhuanInfo数据 (ZhongZhuanInfo) processEngine.getExecutionService().getVariable(pid, "zhongZhuanInfo"); 服务器返回 中转信息 result = zhongZhuanInfo.toString(); <result name="showInfoSUCCESS" type="json"> <param name="root">result</param> </result> 在页面抓取中转信息，回显 $.post("${pageContext.request.cotnextPath}/processinstance_showInfo.action", {"pid": pid}, function(data){ $.messager.alert("流程实例信息", data, "info"); }); 3、 实例运行的流程图查看 需要在流程图上面 标记每个 流程运行到哪个任务节点 第一步： 为每条实例记录，添加查看流程图函数 <a href="#" class="easyui-linkbutton" onclick="showPng('<s:property value="#processInstance.id"/>');">查看流程图</a> function showPng(pid){ alert("查看" + pid + "对应流程图"); } 第二步： 流程图查看Action 可以复用 ---- processdefinition_showpng.action?deploymentId= & resourceName= RepositoryService.getResourceAsStream(java.lang.String deploymentId, java.lang.String resourceName) * resourceName 可以通过 deploymentId 动态获得 RepositoryService repositoryService = processEngine.getRepositoryService(); ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery().deploymentId(deploymentId).uniqueResult(); resourceName = processDefinition.getImageResourceName(); 第三步： 点击查看流程图， 获得活动节点坐标 通过 window.showModalDialog() 查看流程图页面 （弹出窗口，显示页面 url地址不能修改 ） function showPng(pid){ //alert("查看" + pid + "对应流程图"); window.showModalDialog("${pageContext.request.contextPath}/processinstance_findactivityinfo.action?pid="+pid); } 查看某一个具体活动节点坐标 String processDefinitionId = "test-1"; // 流程定义的id String activityName = "start1"; // 活动的名称 ActivityCoordinates c = processEngine.getRepositoryService() .getActivityCoordinates(processDefinitionId, activityName); 查看当前流程实例活动所有节点名称 ProcessInstance的 java.util.Set<java.lang.String> findActiveActivityNames() @Override public List<ActivityCoordinates> findActivityCoordinates(String pid) { // 1、 根据流程实例id 获得所有活动节点名称 ProcessInstance processInstance = processEngine.getExecutionService().createProcessInstanceQuery().processInstanceId(pid).uniqueResult(); Set<String> activityNames = processInstance.findActiveActivityNames(); // 2、一个活动节点 --- 对应一个坐标对象 List<ActivityCoordinates> activityCoordinates = new ArrayList<ActivityCoordinates>(); for(String activityName: activityNames){ // 获得每一个活动节点名称 String processDefinitionId = processInstance.getProcessDefinitionId();//流程定义id ActivityCoordinates activityCoordinate = processEngine.getRepositoryService().getActivityCoordinates(processDefinitionId, activityName); activityCoordinates.add(activityCoordinate); } return activityCoordinates; } ============ 为了在下一个页面 可以显示流程图， 根据实例id 查询 发布id @Override public String findDeploymentIdByProcessInstanceId(String pid) { ProcessInstance processInstance = processEngine.getExecutionService().createProcessInstanceQuery().processInstanceId(pid).uniqueResult(); ProcessDefinition processDefinition = processEngine.getRepositoryService().createProcessDefinitionQuery().processDefinitionId(processInstance.getProcessDefinitionId()).uniqueResult(); return processDefinition.getDeploymentId(); } <img src="${pageContext.request.contextPath }/processdefinition_showpng.action?deploymentId=<s:property value="#deploymentId"/>" style="position: absolute;top: 0;left: 0"/> <s:iterator value="#activityCoordinates" var="activityCoordinate"> <div style="width: <s:property value="#activityCoordinate.width"/>px; height: <s:property value="#activityCoordinate.height"/>px; left: <s:property value="#activityCoordinate.x"/>px; top: <s:property value="#activityCoordinate.y"/>px; position: absolute; border-color: red; border-style: solid; border-width: 1px;"> </s:iterator>
