jeesite工作流，已办任务无法读取修改

1、ActTaskService新增以下方法

/**

* 获取流程历史实例对象

* @param procInsId

* @return

*/

@Transactional(readOnly = false)

public HistoricProcessInstance getEndProcIns(String procInsId) {

HistoricProcessInstance his = historyService.createHistoricProcessInstanceQuery().processInstanceId(procInsId).singleResult();

return his;

}

2、ActTaskController增加以下红色代码

 

/**

* 获取流程表单

* @param taskId任务ID

* @param taskName任务名称

* @param taskDefKey 任务环节标识

* @param procInsId 流程实例ID

* @param procDefId 流程定义ID

*/

@RequestMapping(value = "form")

public String form(Act act, HttpServletRequest request, Model model){

String todoStatus=request.getParameter("status");

// 获取流程XML上的表单KEY

String formKey = actTaskService.getFormKey(act.getProcDefId(), act.getTaskDefKey());

// 获取流程实例对象

if (act.getProcInsId() != null){

if("todo".equals(todoStatus)){

act.setProcIns(actTaskService.getProcIns(act.getProcInsId()));

}

            if("finish".equals(todoStatus)){

HistoricProcessInstance historicAact = actTaskService.getEndProcIns(act.getProcInsId());

if(null!=historicAact){

String buk= historicAact.getBusinessKey();

if(StringUtils.isNotBlank(buk)){

int x=buk.indexOf(":");

if(x>-1){

buk=buk.substring(x+1);

act.setBusinessId(buk);

}

}

 

}

/*if(null!=acts&&acts.size()>0){

act.setProcIns(acts.get(0).getProcIns());

}*/

}

 

}

 

return "redirect:" + ActUtils.getFormUrl(formKey, act);

 

//// 传递参数到视图

//model.addAttribute("act", act);

//model.addAttribute("formUrl", formUrl);

//return "modules/act/actTaskForm";

}
