任务分配 1. 固定分配在绘制流程时直接指定 Assignee测试package com.sw.camundademo; import org.camunda.bpm.engine.RepositoryService; import org.camunda.bpm.engine.RuntimeService; import org.camunda.bpm.engine.TaskService; import org.camunda.bpm.engine.repository.Deployment; import org.camunda.bpm.engine.runtime.ProcessInstance; import org.junit.jupiter.api.Test; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; /** * @Author Suaxi * @Date 2024/7/3 22:11 * @Description */ @SpringBootTest public class AssigneeTest { @Autowired private RepositoryService repositoryService; @Autowired private RuntimeService runtimeService; @Autowired private TaskService taskService; @Test public void deploy() { Deployment deploy = repositoryService.createDeployment() .name("请假流程-固定分配") .addClasspathResource("flow/01.任务分配-固定分配.bpmn") .deploy(); System.out.println(deploy.getId()); } @Test public void startProcess() { ProcessInstance processInstance = runtimeService.startProcessInstanceById("Process_0sa1c18:1:db75f76f-3946-11ef-9303-a8a1592cf182"); System.out.println("processInstance.getId() = " + processInstance.getId()); } @Test public void completeTask() { taskService.complete("44488821-3947-11ef-98ee-a8a1592cf182"); } } 2. 值表达式通过 ${value} 的形式来设置 Assignee测试package com.sw.camundademo; import org.camunda.bpm.engine.RepositoryService; import org.camunda.bpm.engine.RuntimeService; import org.camunda.bpm.engine.TaskService; import org.camunda.bpm.engine.repository.Deployment; import org.camunda.bpm.engine.runtime.ProcessInstance; import org.junit.jupiter.api.Test; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import java.util.HashMap; import java.util.Map; /** * @Author Suaxi * @Date 2024/7/3 22:11 * @Description */ @SpringBootTest public class AssigneeTest { @Autowired private RepositoryService repositoryService; @Autowired private RuntimeService runtimeService; @Autowired private TaskService taskService; @Test public void deploy() { Deployment deploy = repositoryService.createDeployment() .name("请假流程-值表达式") .addClasspathResource("flow/02.任务分配-值表达式.bpmn") .deploy(); System.out.println(deploy.getId()); } @Test public void startProcess() { Map<String, Object> variables = new HashMap<>(4); variables.put("user1", "admin"); ProcessInstance processInstance = runtimeService.startProcessInstanceById("Process_0nn4skb:1:cfb647fa-3949-11ef-83c2-a8a1592cf182", variables); System.out.println("processInstance.getId() = " + processInstance.getId()); } @Test public void completeTaskVariables() { Map<String, Object> variables = new HashMap<>(4); variables.put("user2", "admin"); taskService.complete("34ca22b2-394a-11ef-896b-a8a1592cf182", variables); } } 3. 方法表达式与值表达式类似，当调用无参的方法时，要在表达式方法名的末尾添加括号（与值表达式做区分），如：# assigneeService是容器中的bean对象，通过调用getAssignee()方法来设置 Assignee ${assigneeService.getAssignee()} ${assigneeService.getAssignee("method expression test")}测试package com.sw.camundademo.service; import lombok.extern.slf4j.Slf4j; import org.springframework.stereotype.Service; /** * @Author Suaxi * @Date 2024/7/3 22:46 * @Description */ @Slf4j @Service public class AssigneeService { public String getAssignee() { log.info("getAssignee方法执行了"); return "admin"; } } package com.sw.camundademo; import org.camunda.bpm.engine.RepositoryService; import org.camunda.bpm.engine.RuntimeService; import org.camunda.bpm.engine.TaskService; import org.camunda.bpm.engine.repository.Deployment; import org.camunda.bpm.engine.runtime.ProcessInstance; import org.junit.jupiter.api.Test; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import java.util.HashMap; import java.util.Map; /** * @Author Suaxi * @Date 2024/7/3 22:11 * @Description */ @SpringBootTest public class AssigneeTest { @Autowired private RepositoryService repositoryService; @Autowired private RuntimeService runtimeService; @Autowired private TaskService taskService; @Test public void deploy() { Deployment deploy = repositoryService.createDeployment() .name("请假流程-方法表达式") .addClasspathResource("flow/03.任务分配-方法表达式.bpmn") .deploy(); System.out.println(deploy.getId()); } @Test public void startProcess() { ProcessInstance processInstance = runtimeService.startProcessInstanceById("Process_128tk93:1:0316ac79-394c-11ef-b118-a8a1592cf182"); System.out.println("processInstance.getId() = " + processInstance.getId()); } @Test public void completeTask() { taskService.complete("3858dc36-394c-11ef-bc0e-a8a1592cf182"); } } 4. 监听器配置可以通过自定义的监听器配置来指定 Assignee监听器（根据流程实例的事件类型 create 设置 Assignee）package com.sw.camundademo.listener; import lombok.extern.slf4j.Slf4j; import org.camunda.bpm.engine.delegate.DelegateTask; import org.camunda.bpm.engine.delegate.TaskListener; /** * @Author Suaxi * @Date 2024/7/3 23:07 * @Description */ @Slf4j public class AssigneeListener implements TaskListener { @Override public void notify(DelegateTask delegateTask) { if (EVENTNAME_CREATE.equals(delegateTask.getEventName())) { log.info("自定义监听器触发了..."); delegateTask.setAssignee("admin"); } } } 流程图绘制（在 Listener 选项卡下配置 Event Type 和具体的监听器全路径类名）测试方法同理以上其他的任务分配方式
