新建springboot项目时勾选activiti，或者在已建立的springboot项目添加以下依赖：
<dependency> <groupid>org.activiti</groupid> <artifactid>activiti-spring-boot-starter-basic</artifactid> <version>6.0.0</version> </dependency>
数据源和activiti配置：
我要评论server:
port: 8081
spring:
datasource:
url: jdbc:mysql://localhost:3306/act5?usessl=true
driver-class-name: com.mysql.jdbc.driver
username: root
password: root
# activiti default configuration
activiti:
database-schema-update: true
check-process-definitions: true
process-definition-location-prefix: classpath:/processes/
# process-definition-location-suffixes:
# - **.bpmn
# - **.bpmn20.xml
history-level: full
在activiti的默认配置中，process-definition-location-prefix 是指定activiti流程描述文件的前缀（即路径），启动时，activiti就会去寻找此路径下的流程描述文件，并且自动部署；suffix 是一个string数组，表示描述文件的默认后缀名，默认以上两种。
package com.yawn.config;
import org.springframework.context.annotation.configuration;
import org.springframework.format.formatterregistry;
import org.springframework.http.httpstatus;
import org.springframework.web.servlet.config.annotation.*;
/**
* created by yawn on 2017/8/5.

@enablewebmvc
@configuration
public class mvcconfig extends webmvcconfigureradapter {
@override
public void addresourcehandlers(resourcehandlerregistry registry) {
registry.addresourcehandler("/static/**").addresourcelocations("classpath:/static/");
registry.addresourcehandler("/templates/**").addresourcelocations("classpath:/templates/");
super.addresourcehandlers(registry);
}
@override
public void addviewcontrollers(viewcontrollerregistry registry) {
registry.addviewcontroller("/index");
registry.addviewcontroller("/user");
registry.addredirectviewcontroller("/","/templates/login.html");
// registry.addstatuscontroller("/403", httpstatus.forbidden);
super.addviewcontrollers(registry);
}
}
配置了数据源和activiti后，启动项目，activiti 的各个服务组件就已经被加入到spring容器中了，所以就可以直接注入使用了。如果在未自动配置的spring环境中，可以使用通过指定bean的init-method来配置activiti的服务组件。
以以下请假流程为例：
private static final string process_define_key = "vacationprocess";
public object startvac(string username, vacation vac) {
identityservice.setauthenticateduserid(username);
// 开始流程
processinstance vacationinstance = runtimeservice.startprocessinstancebykey(process_define_key);
// 查询当前任务
task currenttask = taskservice.createtaskquery().processinstanceid(vacationinstance.getid()).singleresult();
// 申明任务
taskservice.claim(currenttask.getid(), username);
map<string, object> vars = new hashmap<>(4);
vars.put("applyuser", username);
vars.put("days", vac.getdays());
vars.put("reason", vac.getreason());
// 完成任务
taskservice.complete(currenttask.getid(), vars);
return true;
}
public object myaudit(string username) {
list<task> tasklist = taskservice.createtaskquery().taskcandidateuser(username)
.orderbytaskcreatetime().desc().list();
// / 多此一举 tasklist中包含了以下内容(用户的任务中包含了所在用户组的任务)
// group group = identityservice.creategroupquery().groupmember(username).singleresult();
// list<task> list = taskservice.createtaskquery().taskcandidategroup(group.getid()).list();
// tasklist.addall(list);
list<vactask> vactasklist = new arraylist<>();
for (task task : tasklist) {
vactask vactask = new vactask();
vactask.setid(task.getid());
vactask.setname(task.getname());
vactask.setcreatetime(task.getcreatetime());
string instanceid = task.getprocessinstanceid();
processinstance instance = runtimeservice.createprocessinstancequery().processinstanceid(instanceid).singleresult();
vacation vac = getvac(instance);
vactask.setvac(vac);
vactasklist.add(vactask);
}
return vactasklist;
}
private vacation getvac(processinstance instance) {
integer days = runtimeservice.getvariable(instance.getid(), "days", integer.class);
string reason = runtimeservice.getvariable(instance.getid(), "reason", string.class);
vacation vac = new vacation();
vac.setapplyuser(instance.getstartuserid());
vac.setdays(days);
vac.setreason(reason);
date starttime = instance.getstarttime(); // activiti 6 才有
vac.setapplytime(starttime);
vac.setapplystatus(instance.isended() ? "申请结束" : "等待审批");
return vac;
}
package com.yawn.entity;
import java.util.date;
/**
* @author created by yawn on 2018-01-09 14:31
*/
public class vactask {
private string id;
private string name;
private vacation vac;
private date createtime;
// getter setter ...
}
public object passaudit(string username, vactask vactask) {
string taskid = vactask.getid();
string result = vactask.getvac().getresult();
map<string, object> vars = new hashmap<>();
vars.put("result", result);
vars.put("auditor", username);
vars.put("audittime", new date());
taskservice.claim(taskid, username);
taskservice.complete(taskid, vars);
return true;
}
由于已完成的请假在数据库runtime表中查不到（runtime表只保存正在进行的流程示例信息），所以需要在history表中查询。
public object myvacrecord(string username) {
list<historicprocessinstance> hisproinstance = historyservice.createhistoricprocessinstancequery()
.processdefinitionkey(process_define_key).startedby(username).finished()
.orderbyprocessinstanceendtime().desc().list();
list<vacation> vaclist = new arraylist<>();
for (historicprocessinstance hisinstance : hisproinstance) {
vacation vacation = new vacation();
vacation.setapplyuser(hisinstance.getstartuserid());
vacation.setapplytime(hisinstance.getstarttime());
vacation.setapplystatus("申请结束");
list<historicvariableinstance> varinstancelist = historyservice.createhistoricvariableinstancequery()
.processinstanceid(hisinstance.getid()).list();
activitiutil.setvars(vacation, varinstancelist);
vaclist.add(vacation);
}
return vaclist;
}
package com.yawn.util;
import org.activiti.engine.history.historicvariableinstance;
import java.lang.reflect.field;
import java.util.list;
/**
* activiti中使用得到的工具方法
* @author created by yawn on 2018-01-10 16:32

public class activitiutil {
/**

*/
public static <t> void setvars(t entity, list<historicvariableinstance> varinstancelist) {
class<?> tclass = entity.getclass();
try {
for (historicvariableinstance varinstance : varinstancelist) {
field field = tclass.getdeclaredfield(varinstance.getvariablename());
if (field == null) {
continue;
}
field.setaccessible(true);
field.set(entity, varinstance.getvalue());
}
} catch (exception e) {
e.printstacktrace();
}
}
}
