0.springboot项目创建

通过https://start.spring.io/生成纯净的一个springboot工程

1.引入activiti相关依赖

<dependency>
    <groupid>org.activiti</groupid>
    <artifactid>activiti-spring-boot-starter</artifactid>
    <version>7.1.0.m6</version>
</dependency>

2.启动工程并创建activiti数据库

##activiti7中使用spring security,因此启动工程前,需要加入2个文件支持,2个文件的代码如下:

package cn.gzsendi.activitidemotest.config;

import java.util.arrays;
import java.util.list;
import java.util.stream.collectors;

import org.slf4j.logger;
import org.slf4j.loggerfactory;
import org.springframework.context.annotation.bean;
import org.springframework.context.annotation.configuration;
import org.springframework.security.core.authority.simplegrantedauthority;
import org.springframework.security.core.userdetails.user;
import org.springframework.security.core.userdetails.userdetailsservice;
import org.springframework.security.crypto.bcrypt.bcryptpasswordencoder;
import org.springframework.security.crypto.password.passwordencoder;
import org.springframework.security.provisioning.inmemoryuserdetailsmanager;

@configuration
public class activiticonfiguration {
	
	private logger logger = loggerfactory.getlogger(activiticonfiguration.class);
	
	@bean(name = "userdetailsservice")
    public userdetailsservice myuserdetailsservice() {

        inmemoryuserdetailsmanager inmemoryuserdetailsmanager = new inmemoryuserdetailsmanager();

        //用户
        string[][] usersgroupsandroles = {
                {"hefy", "123456", "role_activiti_user"},
                {"liujh", "123456", "role_activiti_admin"},
                {"liuky", "123456", "role_activiti_user"},
                {"admin", "123456", "role_activiti_admin"},
        };

        for (string[] user : usersgroupsandroles) {
            list<string> authoritiesstrings = arrays.aslist(arrays.copyofrange(user, 2, user.length));
            logger.info("> registering new user: " + user[0] + " with the following authorities[" + authoritiesstrings + "]");
            inmemoryuserdetailsmanager.createuser(new user(user[0], passwordencoder().encode(user[1]),
                    authoritiesstrings.stream().map(s -> new simplegrantedauthority(s)).collect(collectors.tolist())));
        }

        return inmemoryuserdetailsmanager;

    }
	
	@bean
    public passwordencoder passwordencoder() {
        return new bcryptpasswordencoder();
    }

}
package cn.gzsendi.activitidemotest.utils;

import java.util.collection;

import org.springframework.beans.factory.annotation.autowired;
import org.springframework.beans.factory.annotation.qualifier;
import org.springframework.security.core.authentication;
import org.springframework.security.core.grantedauthority;
import org.springframework.security.core.context.securitycontextholder;
import org.springframework.security.core.context.securitycontextimpl;
import org.springframework.security.core.userdetails.userdetails;
import org.springframework.security.core.userdetails.userdetailsservice;
import org.springframework.stereotype.component;

import javax.annotation.resource;

@component
public class securityutil {
	
	@autowired
    @qualifier("userdetailsservice")
    private userdetailsservice userdetailsservice;
	
	public void loginas(string username) {

        userdetails user = userdetailsservice.loaduserbyusername(username);
        
        if (user == null) {
            throw new illegalstateexception("user " + username + " doesn't exist, please provide a valid user");
        }

        securitycontextholder.setcontext(new securitycontextimpl(new authentication() {
            @override
            public collection<? extends grantedauthority> getauthorities() {
                return user.getauthorities();
            }

            @override
            public object getcredentials() {
                return user.getpassword();
            }

            @override
            public object getdetails() {
                return user;
            }

            @override
            public object getprincipal() {
                return user;
            }

            @override
            public boolean isauthenticated() {
                return true;
            }

            @override
            public void setauthenticated(boolean isauthenticated) throws illegalargumentexception {

            }

            @override
            public string getname() {
                return user.getusername();
            }
        }));
        
        org.activiti.engine.impl.identity.authentication.setauthenticateduserid(username);
    }

}

##加入activiti7的配置

server.port=8080
server.servlet.context-path=/activitidemotest

spring.datasource.driver-class-name=com.mysql.cj.jdbc.driver
spring.datasource.url=jdbc:mysql://localhost:3306/activitidemo?usessl=false&useunicode=true&characterencoding=utf8&servertimezone=gmt%2b8&allowmultiqueries=true
spring.datasource.username=root
spring.datasource.password=123456

spring.activiti.database-schema-update=true
spring.activiti.db-history-used=true
spring.activiti.history-level=full
spring.activiti.check-process-definitions=false
spring.activiti.deployment-mode=never-fail
spring.activiti.process-definition-location-prefix=classpath:/process/

##启动springboot工程,让系统启动时帮我们建好25张表 2.安装activiti插件(设计器) ##idea

file->settings->plugins,然后找actibpm进行安装。

##流程图中乱码问题先提前设置防止:

修改idea64.exe.vmoptions文件,在文件中加上如下,然后重启idea

-dfile.encoding=utf-8

##进行流程设计

file->new->bpmnfile

设计好后,修改process1.bpmn成process1.xml,然后右键export file导出成process1.jpg,再将process1.bpmn修改成process1.bpmn20.xml,最后将2个文件放在process文件夹

3.流程部署

使用activiti提供的api把流程定义内容存储起来,activiti执行把流程定义内容存储在数据库中。

package cn.gzsendi.activitidemotest;

/**
 * created by jxlhl on 2021/8/18.
 */

import org.activiti.engine.repositoryservice;
import org.activiti.engine.repository.deployment;
import org.activiti.engine.repository.deploymentbuilder;
import org.junit.test;
import org.junit.runner.runwith;
import org.springframework.beans.factory.annotation.autowired;
import org.springframework.boot.test.context.springboottest;
import org.springframework.test.context.junit4.springrunner;

@runwith(springrunner.class)
@springboottest
public class springbootjunittest {

    //得到repositoryservice实例
    @autowired
    private repositoryservice repositoryservice;

    //0.流程部署,单个文件部署方式
    @test
    public void testdeployment(){

        //使用repositoryservice进行部署
        deploymentbuilder builder = repositoryservice.createdeployment();
        builder.addclasspathresource("process/process1.bpmn20.xml");
        builder.addclasspathresource("process/process1.jpg");
        builder.name("first_activiti_process");
        deployment deployment = builder.deploy();

        //输出部署信息
        system.out.println("流程部署id:" + deployment.getid());
        system.out.println("流程部署名称:" + deployment.getname());

        //流程部署id:125098e1-ffd9-11eb-8847-02004c4f4f50
        //流程部署名称:first_activiti_process

    }

}

执行此操作后activiti会将上边代码中指定的bpmn20文件和图片文件保存在activiti数据库。

流程定义部署后操作activiti的3张表

4.流程实例启动

启动一个流程实例表示开始一次业务流程的运行

  //1.流程实例启动
    @test
    public void teststartprocess(){
        //根据流程定义id启动流程
        processinstance processinstance = runtimeservice.startprocessinstancebykey("myprocess_1");

        //输出实例信息
        system.out.println("流程定义id:" + processinstance.getprocessdefinitionid());
        system.out.println("流程实例id:" + processinstance.getid());
        system.out.println("当前活动id:" + processinstance.getactivityid());

        //流程定义id:myprocess_1:1:12702ed4-ffd9-11eb-8847-02004c4f4f50
        //流程实例id:a9b162aa-ffda-11eb-bad1-02004c4f4f50
        //当前活动id:null

    }

流程实例启动,将操作以下几个数据库表

act_hi_actinst 流程实例执行历史
act_hi_identitylink 流程的参与用户历史信息
act_hi_procinst 流程实例历史信息
act_hi_taskinst 流程任务历史信息
act_ru_execution 流程执行信息
act_ru_identitylink 流程的参与用户信息
act_ru_task 任务信息

5.任务查询

流程启动后,任务的负责人就可以查询自己当前需要处理的任务,查询出来的任务都是该用户的待办任务。

 //2.任务查询
    //流程启动后,任务的负责人就可以查询自己当前需要处理的任务,查询出来的任务都是该用户的待办任务。
    @test
    public void testfindpersonaltasklist() {
        //任务负责人
        string assignee = "liuky";

        //根据流程key 和 任务负责人 查询任务
        list<task> list = taskservice.createtaskquery()
                .processdefinitionkey("myprocess_1")
                .taskassignee(assignee)
                .list();

        for (task task : list) {

            system.out.println("流程实例id:" + task.getprocessinstanceid());
            system.out.println("任务id:" + task.getid());
            system.out.println("任务负责人:" + task.getassignee());
            system.out.println("任务名称:" + task.getname());

        }

        //流程实例id:a9b162aa-ffda-11eb-bad1-02004c4f4f50
        //任务id:a9b5815e-ffda-11eb-bad1-02004c4f4f50
        //任务负责人:liuky
        //任务名称:提交申请

    }

6. 完成任务

 @test
    public void complettask(){

        //根据流程key和任务的负责人查询任务并选择其中的一个任务处理,这里用的
        //是singleresult返回一条,真实环境中是通过步骤5中查询出所有的任务,然后在页面上选择一个任务进行处理.
        task task = taskservice.createtaskquery()
                .processdefinitionkey("myprocess_1") //流程key
                .taskassignee("liuky")  //要查询的负责人
                .singleresult();
                
        //完成任务,参数:任务id
        taskservice.complete(task.getid());

    }

7.流程结束,或流程流转过程中的历史信息查询

   //流程结束,或流程流转过程中的历史信息查询
    @test
    public void findhistoryinfo(){

        //获取 actinst表的查询对象
        historicactivityinstancequery instancequery = historyservice.createhistoricactivityinstancequery();
        //查询 actinst表,条件:根据 instanceid 查询
        instancequery.processinstanceid("fb5b7674-ffde-11eb-91f8-02004c4f4f50");
        //增加排序操作,orderbyhistoricactivityinstancestarttime 根据开始时间排序 asc 升序
        instancequery.orderbyhistoricactivityinstancestarttime().asc();
        //查询所有内容
        list<historicactivityinstance> activityinstancelist = instancequery.list();
        //输出结果
        for (historicactivityinstance hi : activityinstancelist) {

            system.out.println("");
            system.out.println("===================-===============");
            system.out.println(hi.getstarttime());
            system.out.println(hi.getassignee());
            system.out.println(hi.getactivityid());
            system.out.println(hi.getactivityname());
            system.out.println(hi.getprocessdefinitionid());
            system.out.println(hi.getprocessinstanceid());
            system.out.println("===================-===============");
            system.out.println("");

        }
    }

8.其他api测试

8.1 流程定义信息查询

查询流程相关信息,包含流程定义,流程部署,流程定义版本

@test
    public void queryprocessdefinition(){

        //得到processdefinitionquery对象
        processdefinitionquery processdefinitionquery = repositoryservice.createprocessdefinitionquery();

        //查询出当前所有的流程定义
        list<processdefinition> definitionlist = processdefinitionquery.processdefinitionkey("myprocess_1")
                .orderbyprocessdefinitionversion()
                .desc()
                .list();

        //打印结果
        for (processdefinition processdefinition : definitionlist) {
            system.out.println("流程定义 id="+processdefinition.getid());
            system.out.println("流程定义 name="+processdefinition.getname());
            system.out.println("流程定义 key="+processdefinition.getkey());
            system.out.println("流程定义 version="+processdefinition.getversion());
            system.out.println("流程部署id ="+processdefinition.getdeploymentid());
        }

    }

8.2 删除流程

  //删除流程
    @test
    public void deletedeployment(){

        string deploymentid = "125098e1-ffd9-11eb-8847-02004c4f4f50";

        //删除流程定义,如果该流程定义已有流程实例启动则删除时出错
        repositoryservice.deletedeployment(deploymentid);

        //设置true 级联删除流程定义,即使该流程有流程实例启动也可以删除,设置为false非级别删除方式,如果流程
        //repositoryservice.deletedeployment(deploymentid, true);

    }
