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;@Configurationpublic 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;@Componentpublic 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=8080server.servlet.context-path=/activitidemotestspring.datasource.driver-class-name=com.mysql.cj.jdbc.Driverspring.datasource.url=jdbc:mysql://localhost:3306/activitidemo?useSSL=false&useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&allowMultiQueries=truespring.datasource.username=rootspring.datasource.password=123456spring.activiti.database-schema-update=truespring.activiti.db-history-used=truespring.activiti.history-level=fullspring.activiti.check-process-definitions=falsespring.activiti.deployment-mode=never-failspring.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)@SpringBootTestpublic 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idtaskService.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); }9.demo源码下载
