Activiti7开发(二)-流程定义
1.部署流程模型为流程定义
@PostMapping(value = "/addDeploymentByString")
public AjaxResult addDeploymentByString(@RequestParam("stringBPMN") String stringBPMN) {
processDefinitionService.addDeploymentByString(stringBPMN);
return AjaxResult.success();
}
public void addDeploymentByString(String stringBPMN) {
repositoryService.createDeployment()
.addString("CreateWithBPMNJS.bpmn", stringBPMN)
.deploy();
}
说明：stringBPMN该字符串其实就是一个xml,但与Modeler生成的内容不同；此处没有创建模型，直接进行部署。如果后期需求变更，可以基于该模型进行修改后再次部署，区别在于版本号+1，同时最新创建的流程实例是根据最新版本的流程定义创建的。
2.挂起/激活流程定义
@PostMapping("/suspendOrActiveApply")
@ResponseBody
public AjaxResult suspendOrActiveApply(@RequestBody ProcessDefinitionDTO processDefinition) {
processDefinitionService.suspendOrActiveApply(processDefinition.getId(), processDefinition.getSuspendState());
return AjaxResult.success();
}
public void suspendOrActiveApply(String id, Integer suspendState) {
if (1==suspendState) {
// 当流程定义被挂起时，已经发起的该流程定义的流程实例不受影响（如果选择级联挂起则流程实例也会被挂起）。
// 当流程定义被挂起时，无法发起新的该流程定义的流程实例。
// 直观变化：act_re_procdef 的 SUSPENSION_STATE_ 为 2
repositoryService.suspendProcessDefinitionById(id);
} else if (2==suspendState) {
repositoryService.activateProcessDefinitionById(id);
}
}
3.删除流程定义
@DeleteMapping(value = "/remove/{deploymentId}")
public AjaxResult delDefinition(@PathVariable("deploymentId") String deploymentId) {
return toAjax(processDefinitionService.deleteProcessDefinitionById(deploymentId));
}
public int deleteProcessDefinitionById(String id) {
repositoryService.deleteDeployment(id, false);
return 1;
}
4.查询流程定义
@GetMapping(value = "/list")
public TableDataInfo list(ProcessDefinitionDTO processDefinition) {
PageDomain pageDomain = TableSupport.buildPageRequest();
return getDataTable(processDefinitionService.selectProcessDefinitionList(processDefinition, pageDomain));
}
public Page<ProcessDefinitionDTO> selectProcessDefinitionList(ProcessDefinitionDTO processDefinition, PageDomain pageDomain) {
Page<ProcessDefinitionDTO> list = new Page<>();
ProcessDefinitionQuery processDefinitionQuery = repositoryService.createProcessDefinitionQuery().orderByProcessDefinitionId().orderByProcessDefinitionVersion().desc();
if (StringUtils.isNotBlank(processDefinition.getName())) {
processDefinitionQuery.processDefinitionNameLike("%" + processDefinition.getName() + "%");
}
if (StringUtils.isNotBlank(processDefinition.getKey())) {
processDefinitionQuery.processDefinitionKeyLike("%" + processDefinition.getKey() + "%");
}
List<ProcessDefinition> processDefinitions = processDefinitionQuery.listPage((pageDomain.getPageNum() - 1) * pageDomain.getPageSize(), pageDomain.getPageSize());
long count = processDefinitionQuery.count();
list.setTotal(count);
if (count!=0) {
//把流程id拿到(去重)
Set<String> ids = processDefinitions.parallelStream().map(pdl -> pdl.getDeploymentId()).collect(Collectors.toSet());
//id deployTime
List<ActReDeploymentVO> actReDeploymentVOS = actReDeploymentMapper.selectActReDeploymentByIds(ids);
// id name key version deploymentId resourceName
List<ProcessDefinitionDTO> processDefinitionDTOS = processDefinitions.stream()
.map(pd -> new ProcessDefinitionDTO((ProcessDefinitionEntityImpl) pd, actReDeploymentVOS.parallelStream().filter(ard -> pd.getDeploymentId().equals(ard.getId())).findAny().orElse(new ActReDeploymentVO())))
.collect(Collectors.toList());
list.addAll(processDefinitionDTOS);
}
return list;
}
5.上传并部署流程定义
public AjaxResult uploadStreamAndDeployment(@RequestParam("file") MultipartFile file) throws IOException {
processDefinitionService.uploadStreamAndDeployment(file);
return AjaxResult.success();
}
public void uploadStreamAndDeployment(MultipartFile file) throws IOException {
// 获取上传的文件名
String fileName = file.getOriginalFilename();
// 得到输入流（字节流）对象
InputStream fileInputStream = file.getInputStream();
// 文件的扩展名
String extension = FilenameUtils.getExtension(fileName);
if (extension.equals("zip")) {
ZipInputStream zip = new ZipInputStream(fileInputStream);
repositoryService.createDeployment()//初始化流程
.addZipInputStream(zip)
.deploy();
} else {
repositoryService.createDeployment()//初始化流程
.addInputStream(fileName, fileInputStream)
.deploy();
}
}
6.查看流程模型
public void getProcessDefineXML(HttpServletResponse response,@RequestParam("deploymentId") String deploymentId,@RequestParam("resourceName") String resourceName) throws IOException {
processDefinitionService.getProcessDefineXML(response, deploymentId, resourceName);
}
public void getProcessDefineXML(HttpServletResponse response, String deploymentId, String resourceName) throws IOException {
InputStream inputStream = repositoryService.getResourceAsStream(deploymentId, resourceName);
int count = inputStream.available();
byte[] bytes = new byte[count];
response.setContentType("text/xml");
OutputStream outputStream = response.getOutputStream();
while (inputStream.read(bytes) != -1) {
outputStream.write(bytes);
}
inputStream.close();
}
返回是xml
<?xml version="1.0" encoding="UTF-8"?>
