}
```
## 3. 流程的执行过程
```
package com.fengye.example.controller;
import com.fengye.example.service.ActivitiService;
import org.activiti.engine.task.Task;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.ArrayList;
import java.util.List;
@RestController
public class MyRestController {
@Autowired
private ActivitiService myService;
//开启流程实例
@RequestMapping(value = "/process/{personId}/{compId}", method = RequestMethod.GET)
public void startProcessInstance(@PathVariable Long personId, @PathVariable Long compId) {
myService.startProcess(personId, compId);
}
//获取当前人的任务
@RequestMapping(value = "/tasks", method = RequestMethod.GET)
public List getTasks(@RequestParam String assignee) {
List tasks = myService.getTasks(assignee);
List dtos = new ArrayList();
for (Task task : tasks) {
dtos.add(new TaskRepresentation(task.getId(), task.getName()));
}
return dtos;
}
//完成任务
@RequestMapping(value = "/complete/{joinApproved}/{taskId}", method = RequestMethod.GET)
public String complete(@PathVariable Boolean joinApproved, @PathVariable String taskId) {
myService.completeTasks(joinApproved, taskId);
return "ok";
}
//Task的dto
static class TaskRepresentation
{
private String id;
private String name;
public TaskRepresentation(String id, String name) {
this.id = id;
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
}
```
## 4. 流程的执行过程
要加入的公司id为1，申请加入的人的id为2:访问
http://localhost:8080/process/2/1
查看数据库表(ACT_RU_TASK ACT_RU_IDENTITYLINK)的变化
http://localhost:8080/tasks?assignee=admin 查看admin用户的任务
访问http://localhost:8080/complete/true/10 完成任务，true为同意(可以选择false)
