2.部署流程
/**
* 部署流程
*/
@Test
public void deploymentProcessDefinition() {
//1,得到一个service可以操作act_ge_bytearray act_re_deployment act_re_procdef
RepositoryService repositoryService = this.processEngine.getRepositoryService();
Deployment deploy = repositoryService.createDeployment().addClasspathResource("HelloWorld.bpmn")
.addClasspathResource("HelloWorld.png")
.name("请假流程002")//设置流程部署名称 act_re_deployment里面的name属性值
.deploy();//部署
System.out.println("部署成功:流程部署ID:"+deploy.getId()+" 流程部署名称："+deploy.getName());
}
3.启动流程
/**
* 启动流程
*/
@Test
public void startProcess() {
//1,得到启动流程的service
RuntimeService runtimeService = this.processEngine.getRuntimeService();
// String processDefinitionId="HelloWorld:1:4";
// runtimeService.startProcessInstanceById(processDefinitionId);
String processDefinitionKey="HelloWorld";
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processDefinitionKey);//启动的永远是最新版本的流程
System.out.println("流程启动成功");
System.out.println("部署ID:"+processInstance.getDeploymentId());//指act_re_deployment的id
System.out.println("流程定义ID:"+processInstance.getProcessDefinitionId());//act_re_procdef里面的id
System.out.println("流程实例ID:"+processInstance.getId());//act_ru_execution这个表里面的id
}
4.任务查询
/**
* 任务查询
*/
@Test
public void queryTask() {
TaskService taskService = this.processEngine.getTaskService();
String assignee="王五";
List<Task> list = taskService.createTaskQuery().taskAssignee(assignee).list();
for (Task task : list) {
System.out.println("任务ID:"+task.getId());
System.out.println("执行实例ID:"+task.getExecutionId());
System.out.println("流程实例ID:"+task.getProcessInstanceId());
System.out.println("任务名称:"+task.getName());
System.out.println("任务定义的Key:"+task.getTaskDefinitionKey());
System.out.println("任务办理人:"+task.getAssignee());
System.out.println("#####################");
}
}
5.完成任务
/**
* 完成任务
*/
@Test
public void completeTask() {
TaskService taskService = this.processEngine.getTaskService();
String taskId="10002";
taskService.complete(taskId);
System.out.println("任务完成成功");
}
08【掌握】管理流程定义
1.流程部署
private ProcessEngine processEngine=ProcessEngines.getDefaultProcessEngine();
/**
* 流程部署
* 使用addClasspathResource
*/
@Test
public void deployProcessDefinition1() {
RepositoryService repositoryService = processEngine.getRepositoryService();
Deployment deploy = repositoryService.createDeployment().addClasspathResource("HelloWorld.bpmn")
.addClasspathResource("HelloWorld.png")
.name("请假流程001")
.deploy();
System.out.println("部署成功:流程部署ID:"+deploy.getId()+" 流程部署名称："+deploy.getName());
}
/**
* 流程部署
* 使用addInputStream
*/
@Test
public void deployProcessDefinition2() {
RepositoryService repositoryService = processEngine.getRepositoryService();
/**this.getClass().getResourceAsStream()
|--里面没有 / 代表相对于当前类所在包的路径
|--里面有 / 代表相对的源码包的根路径
**/
InputStream bpmnInputStream=this.getClass().getResourceAsStream("HelloWorld.bpmn");
InputStream pngInputStream=this.getClass().getResourceAsStream("HelloWorld.png");
/**
* this.getClass().getClassLoader().getResourceAsStream()
* |--里面没有 / 代表相对于当前源码包的路径
* |--没有/ 相取于项目路径
*/
// InputStream bpmnInputStream=this.getClass().getClassLoader().getResourceAsStream("HelloWorld.bpmn");
// InputStream pngInputStream=this.getClass().getClassLoader().getResourceAsStream("HelloWorld.png");
System.out.println(bpmnInputStream);
Deployment deploy = repositoryService.createDeployment()
.addInputStream("HelloWorld.bpmn", bpmnInputStream)
.addInputStream("HelloWorld.png", pngInputStream)
.name("请假流程002")
.deploy();
System.out.println("部署成功:流程部署ID:"+deploy.getId()+" 流程部署名称："+deploy.getName());
}
/**
* 流程部署
* 使用addInputStream
*/
@Test
public void deployProcessDefinition3() {
RepositoryService repositoryService = processEngine.getRepositoryService();
ZipInputStream zipInputStream=new ZipInputStream(this.getClass().getResourceAsStream("/HelloWorld.zip"));
Deployment deploy = repositoryService.createDeployment()
.addZipInputStream(zipInputStream)
.name("请假流程003")
.deploy();
System.out.println("部署成功:流程部署ID:"+deploy.getId()+" 流程部署名称："+deploy.getName());
}
2.查询流程部署
/**
* 查询流程部署
*/
@Test
public void queryProcessDeploy() {
RepositoryService repositoryService = processEngine.getRepositoryService();
//创建一个查询对象
List<Deployment> list = repositoryService.createDeploymentQuery()
//查询条件
// .deploymentId(deploymentId)//根据部署ID查询流程部署信息
// .deploymentKey(key) 根据部署的KEY查询流程部署信息
// .deploymentKeyLike(keyLike) //根据部署KEY模糊查询
// .deploymentName(name)//根据部署名称等值查询
// .deploymentNameLike(nameLike)//根据部署名称模糊查询
//排序条件
// .orderByDeploymentId().asc()//根据流程部署ID 升序
// .orderByDeploymenTime().desc() //根据流程部署时间 降序
//结果集
.list() //返回list集合
// .singleResult() 返回单条数据对象
// .count() //返回查询总条
// .listPage(firstResult, maxResults)//分查查询
;
for (Deployment d : list) {
System.out.println("部署ID:"+d.getId());
System.out.println("部署名称:"+d.getName());
System.out.println("部署KEY:"+d.getKey());
System.out.println("部署CATEGORY:"+d.getCategory());
System.out.println("部署TENANTID:"+d.getTenantId());
System.out.println("部署时间:"+d.getDeploymentTime());
System.out.println("######################");
}
}
3.查询流程定义
/**
* 查询流程定义
*/
@Test
public void queryProcessDefinition() {
RepositoryService repositoryService = processEngine.getRepositoryService();
List<ProcessDefinition> list = repositoryService.createProcessDefinitionQuery()
//查询条件
// .processDefinitionId(processDefinitionId)//根据流程定义ID等值查询
// .processDefinitionIds(processDefinitionIds) processDefinitionIds就一个set集合，in (set)
// .processDefinitionCategory(processDefinitionCategory)
// .processDefinitionCategoryLike(processDefinitionCategoryLike)
// .processDefinitionKey(processDefinitionKey)根据流程定义的key查询
// .processDefinitionKeyLike(processDefinitionKeyLike)根据流程定义的key模糊查询
// .processDefinitionName(processDefinitionName)根据流程定义的名称等值查询
// .processDefinitionNameLike(processDefinitionNameLike)根据流程定义的名称模糊查询
// .deploymentId("1") //根据流程部署ID查询
// .deploymentIds(deploymentIds)根据流程部署ID的set集合查询
//排序条件
// .orderByProcessDefinitionVersion().asc()
//结果集
// .singleResult();
.list();
for (ProcessDefinition processDefinition : list) {
System.out.println("流程定义ID:"+processDefinition.getId());
System.out.println("流程定义名称:"+processDefinition.getName());
System.out.println("流程定义KEY:"+processDefinition.getKey());
System.out.println("流程部署ID:"+processDefinition.getDeploymentId());
System.out.println("######################");
}
}
4.删除流程定义和部署
/**
* 删除流程定义和部署
*/
@Test
public void deleteProcessDeployment() {
RepositoryService repositoryService = processEngine.getRepositoryService();
String deploymentId="7501";
// repositoryService.deleteDeployment(deploymentId);//根据流程部署ID删除 如果流程正在使用则会抛异常
repositoryService.deleteDeployment(deploymentId, true);//根据流程部署ID删除 如果流程再在使用也能级联删除
System.out.println("删除成功");
}
5.修改流程定义
重新部署让版本增加
6.查询资源文件[图片]
/**
* 查询流程图
* @throws FileNotFoundException
*/
@Test
public void queryProcessDeploymentImage() throws Exception {
RepositoryService repositoryService = processEngine.getRepositoryService();
String deploymentId="2501";
List<String> names = repositoryService.getDeploymentResourceNames(deploymentId);
for (String resourceName : names) {
System.out.println(resourceName);
if(resourceName.endsWith(".png")) {
InputStream stream = repositoryService.getResourceAsStream(deploymentId, resourceName);
File file=new File("D:/"+resourceName);
FileOutputStream fos=new FileOutputStream(file);
int len=0;
byte[] b=new byte[1024];
while((len=stream.read(b))!=-1) {
fos.write(b, 0, len);
fos.flush();
}
fos.close();
stream.close();
}
}
System.out.println("资源文件保存成功");
}
/**
* 查询流程图
* @throws已知流程定义id act_re_procdef 的id
*
*/
@Test
public void queryProcessDeploymentImage2() throws Exception {
RepositoryService repositoryService = processEngine.getRepositoryService();
String processDefinitionId="HelloWorld:2:2504";
//1,根据流程定义ID查询流程定义的对象
ProcessDefinition processDefinition=repositoryService.createProcessDefinitionQuery()
.processDefinitionId(processDefinitionId)
.singleResult();
String deploymentId=processDefinition.getDeploymentId();
String resourceName=processDefinition.getDiagramResourceName();
InputStream stream = repositoryService.getResourceAsStream(deploymentId, resourceName);
File file=new File("D:/"+resourceName);
FileOutputStream fos=new FileOutputStream(file);
int len=0;
byte[] b=new byte[1024];
while((len=stream.read(b))!=-1) {
fos.write(b, 0, len);
fos.flush();
}
fos.close();
stream.close();
System.out.println("资源文件保存成功");
}
7.附加功能：查询最新版本的流程定义
/**
* 7：附加功能：查询最新版本的流程定义
*/
@Test
public void queryTopNewProcessDefinition() {
RepositoryService repositoryService = processEngine.getRepositoryService();
List<ProcessDefinition> list = repositoryService.createProcessDefinitionQuery().latestVersion().list();
for (ProcessDefinition processDefinition : list) {
System.out.println("流程定义ID:"+processDefinition.getId());
System.out.println("流程定义名称:"+processDefinition.getName());
System.out.println("流程定义KEY:"+processDefinition.getKey());
System.out.println("流程部署ID:"+processDefinition.getDeploymentId());
System.out.println("流程定义版本:"+processDefinition.getVersion());
System.out.println("######################");
}
}
/**

*/
@Test
public void queryTopNewProcessDefinition2() {
RepositoryService repositoryService = processEngine.getRepositoryService();
List<ProcessDefinition> list = repositoryService.createProcessDefinitionQuery()
.orderByProcessDefinitionVersion().asc()
.list();
Map<String,ProcessDefinition> map=new HashMap<>();
for (ProcessDefinition processDefinition : list) {
map.put(processDefinition.getKey(), processDefinition);
}
for (ProcessDefinition processDefinition : map.values()) {
System.out.println("流程定义ID:"+processDefinition.getId());
System.out.println("流程定义名称:"+processDefinition.getName());
System.out.println("流程定义KEY:"+processDefinition.getKey());
System.out.println("流程部署ID:"+processDefinition.getDeploymentId());
System.out.println("流程定义版本:"+processDefinition.getVersion());
System.out.println("######################");
}
}
8.附加功能：删除流程定义（删除key相同的所有不同版本的流程定义）
/**
* 8，附加功能：删除流程定义（删除key相同的所有不同版本的流程定义）
*
* 已知key
*/
@Test
public void deleteAllSameVersionProcessDefinition() {
RepositoryService repositoryService = this.processEngine.getRepositoryService();
String processDefinitionKey="HelloWorld2";
//根据KEY找流程定义的对象
List<ProcessDefinition> list = repositoryService.createProcessDefinitionQuery().processDefinitionKey(processDefinitionKey).list();
for (ProcessDefinition processDefinition : list) {
String deploymentId = processDefinition.getDeploymentId();
repositoryService.deleteDeployment(deploymentId, true);
}
}
