Activiti7与SpringBoot整合后，默认情况下，集成了SpringSecurity安全框架，这样我们就要去准备SpringSecurity整合进来的相关用户权限配置信息
1）添加SecurityUtil类


为了能够快速实现SpringSecurity安全框架的配置，所添加的一个组件。


@Component
public class SecurityUtil {

  private Logger logger = LoggerFactory.getLogger(SecurityUtil.class);

  @Autowired
  @Qualifier("myUserDetailsService")
  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");
    }
    logger.info("> Logged in as: " + username);
    SecurityContextHolder.setContext(new SecurityContextImpl(new Authentication() {
      @Override
      public Collection<"htmlcode">

@Configuration
public class DemoApplicationConfiguration {

  private Logger logger = LoggerFactory.getLogger(DemoApplicationConfiguration.class);

  @Bean
  public UserDetailsService myUserDetailsService() {

    InMemoryUserDetailsManager inMemoryUserDetailsManager = new InMemoryUserDetailsManager();

    String[][] usersGroupsAndRoles = {
        {"salaboy", "password", "ROLE_ACTIVITI_USER", "GROUP_activitiTeam"},
        {"ryandawsonuk", "password", "ROLE_ACTIVITI_USER", "GROUP_activitiTeam"},
        {"erdemedeiros", "password", "ROLE_ACTIVITI_USER", "GROUP_activitiTeam"},
        {"other", "password", "ROLE_ACTIVITI_USER", "GROUP_otherTeam"},
        {"system", "password", "ROLE_ACTIVITI_USER"},
        {"admin", "password", "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();
  }

}




4）创建测试类


@SpringBootTest
@Slf4j
class ActivitiApplicationTests {

  @Autowired
  private ProcessEngine processEngine;

  /**
   * 流程定义的部署
   */
  @Test
  public void createDeploy() { 
    RepositoryService repositoryService = processEngine.getRepositoryService();

    Deployment deployment = repositoryService.createDeployment()
        .addClasspathResource("diagram/holiday.bpmn")//添加bpmn资源
        .addClasspathResource("diagram/holiday.png")
        .name("请假申请单流程")
        .deploy(); 
        
    log.info("流程部署id:" + deployment.getName());
    log.info("流程部署名称:" + deployment.getId());
  }
}




运行结果：




遇到的问题：


1）历史表默认不会生成，需在application.yml中配置


spring:
 activiti:
  #检测历史表是否存在
  db-history-used: true
  #记录历史等级 可配置的历史级别有none, activity, audit, full
  history-level: full
