这篇文章将为大家详细讲解有关Activiti7如何整合Springboot使用记录，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
通过https://start.spring.io/生成纯净的一个springboot工程
<dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring-boot-starter</artifactId> <version>7.1.0.M6</version> </dependency>
##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
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
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
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 } @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()); } //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(""); } }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()); } } //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); }关于“Activiti7如何整合Springboot使用记录”这篇文章就分享到这里了，希望以上内容可以对大家有一定的帮助，使各位可以学到更多知识，如果觉得文章不错，请把它分享出去让更多的人看到。
