添加SpringSecurity的相关配置类以及启动类

由于activity7和SpringSecurity是强耦合的所以在使用activity7进行web开发时要注意添加SecurityUtil 和DemoApplicationConfiguration 两个工具类，这两个类可以在官方提供的案例中找到，activity官网地址

@Component
public class SecurityUtil {@Autowiredprivate 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() {@Overridepublic Collection<? extends GrantedAuthority> getAuthorities() {return user.getAuthorities();}@Overridepublic Object getCredentials() {return user.getPassword();}@Overridepublic Object getDetails() {return user;}@Overridepublic Object getPrincipal() {return user;}@Overridepublic boolean isAuthenticated() {return true;}@Overridepublic void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {}@Overridepublic String getName() {return user.getUsername();}}));org.activiti.engine.impl.identity.Authentication.setAuthenticatedUserId(username);}
}

@Configuration
@EnableWebSecurity
public class DemoApplicationConfiguration extends WebSecurityConfigurerAdapter {private Logger logger = LoggerFactory.getLogger(DemoApplicationConfiguration.class);@Override@Autowiredpublic void configure(AuthenticationManagerBuilder auth) throws Exception {auth.userDetailsService(myUserDetailsService());}@Beanpublic 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"},{"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;}@Overrideprotected void configure(HttpSecurity http) throws Exception {http.csrf().disable().authorizeRequests().anyRequest().authenticated().and().httpBasic();}@Beanpublic PasswordEncoder passwordEncoder() {return new BCryptPasswordEncoder();}
}

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

编写配置文件application.yml

spring:datasource:url: jdbc:mysql://localhost:3306/activitydb?useUnicode=true&characterEncoding=utf8&serverTimezone=GMTusername : rootpassword : 123driver-class-name: com.mysql.jdbc.Driveractiviti:db-history-used: true

定义一个流程用于测试

注意candidate Groups必须得按照DemoApplicationConfiguration的规则设置，不然进行查询taskRuntime.tasks查不出数据。

编写测试类

查看流程定义信息

@RunWith(SpringRunner.class)
@SpringBootTest
public class ActivitiTest {@Autowiredprivate ProcessRuntime processRuntime;//实现流程定义相关操作@Autowiredprivate TaskRuntime taskRuntime;//任务操作相关类@Autowiredprivate SecurityUtil securityUtil;//springSecurity相关工具类/***  流程定义信息的查看*      注意：activity7和SpringBoot整合后，会自动部署resources/processes/*.bpmn*/@Testpublic void testDefinition(){//屏蔽AuthenticationCredentialsNotFoundException报错securityUtil.logInAs("salaboy");//springSecurity的认证工作//分页查询出流程定义信息Page processDefinitionPage = processRuntime.processDefinitions(Pageable.of(0, 10));System.out.println("已部署流程个数:"+processDefinitionPage.getTotalItems());//得到当前部署的每个流程的定义信息for (Object pd : processDefinitionPage.getContent()){System.out.println(pd);}}
}

查询并完成任务

    @Testpublic void testTask(){securityUtil.logInAs("salaboy");Page<Task> taskPage = taskRuntime.tasks(Pageable.of(0, 10));if(taskPage.getTotalItems()>0){//说明有任务for(Task task : taskPage.getContent()){System.out.println("任务:"+task);//拾取任务 candidate="activitiTeam"Task claim = taskRuntime.claim(TaskPayloadBuilder.claim().withTaskId(task.getId()).build());//执行任务taskRuntime.complete(TaskPayloadBuilder.complete().withTaskId(task.getId()).build());System.out.println(task.getId()+"执行完成");}}}

总结

至此: 免费的Activity课程.就学完了。Activity是一个很好的工作流框架，虽然很老了，但其思想还是很值得学习的，主要是新的工作流引擎我没找到白嫖的课程。最后附上我学习时写的代码地址，希望可以帮助大家，如果可以给个关注谢谢！
