    # 记录历史等级 可配置的历史级别有none, activity, audit, full
    # none：不保存任何的历史数据，因此，在流程执行过程中，这是最高效的。
    # activity：级别高于none，保存流程实例与流程行为，其他数据不保存。
    # audit：除activity级别会保存的数据外，还会保存全部的流程任务及其属性。
    # full：保存历史数据的最高级别，除了会保存audit级别的数据外，还会保存其他全部流程相关的细节数据，包括一些流程参数等。
    history-level: full

主启动类：

@SpringBootApplication
public class Activiti7Application {
    public static void main(String[] args) {
        SpringApplication.run(Activiti7Application.class, args);
    }
}

测试类：

@SpringBootTest
public class Activiti7Test01 {

    @Autowired
    ProcessEngine processEngine;

    @Test
    public void test1() {
        System.out.println(processEngine);
    }

}

运行结果：

查询历史信息：整合了SpringBoot后，所有的activiti相关的service可以通过@Autowired注入获取

    
    @Autowired
    HistoryService historyService;

	@Test
    public void historyInfo(){
        // 1. 实例化流程引擎实例
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        // 2. 获取 HistoryService
        HistoryService historyService = processEngine.getHistoryService();
        // 3. 获取节点历史记录查询对象 ACT_HI_ACTINST 表
        HistoricActivityInstanceQuery query = historyService.createHistoricActivityInstanceQuery();
        // 实例 id
        String processInstanceId = "5001";
        List<HistoricActivityInstance> list = query.processInstanceId(processInstanceId)
                .orderByHistoricActivityInstanceStartTime() // 根据开始时间排序 asc 升序
                .asc()
                .list();
        for (HistoricActivityInstance hi : list) {
            System.out.print("流程定义ID: " + hi.getProcessDefinitionId());
            System.out.print("，流程实例ID: " + hi.getProcessInstanceId());
            System.out.print("，节点ID: " + hi.getActivityId());
            System.out.print("，节点名称: " + hi.getActivityName());
            System.out.print("，任务办理人：" + hi.getAssignee());
            System.out.print("，开始时间：" + hi.getStartTime());
            System.out.println("结束时间：" + hi.getEndTime());
        }
    }

整合SpringSecurity

activiti7 与 SpringSecurity 强耦合， 创建安全认证配置类SpringSecurityConfig 类

@Configuration
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {
    private final Logger logger = LoggerFactory.getLogger(SpringSecurityConfig.class);

    /**
     * 内存 UserDetailsManager
     */
    @Bean
    public UserDetailsService myUserDetailsService() {
        InMemoryUserDetailsManager inMemoryUserDetailsManager = new
                InMemoryUserDetailsManager();
        // 初始化账号角色数据
        addGroupAndRoles(inMemoryUserDetailsManager);
        return inMemoryUserDetailsManager;
    }

    private void addGroupAndRoles(UserDetailsManager userDetailsManager) {
        // 注意：后面流程办理人，必须是当前存在的用户 username
        String[][] usersGroupsAndRoles = {
                {"zhangsan", "123456", "ROLE_ACTIVITI_USER", "GROUP_activitiTeam"},
                {"wj1", "123456", "ROLE_ACTIVITI_USER", "GROUP_activitiTeam"},
                {"wj2", "123456", "ROLE_ACTIVITI_USER", "GROUP_activitiTeam"},
                {"张三", "123456", "ROLE_ACTIVITI_ADMIN", "GROUP_otherTeam"},
                {"李四", "123456", "ROLE_ACTIVITI_ADMIN", "GROUP_otherTeam"},
                {"王五", "123456", "ROLE_ACTIVITI_ADMIN", "GROUP_otherTeam"}
        };

        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 + "]");
            userDetailsManager.createUser(new User(user[0],
                    passwordEncoder().encode(user[1]),
                    authoritiesStrings.stream().map(SimpleGrantedAuthority::new).collect(Collectors.toList())));
        }
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}
