2.數據庫配置

spring:datasource:url: jdbc:mysql://localhost:3306/activiti?useUnicode=true&characterEncoding=utf8&serverTimezone=GMTusername : rootpassword : rootdriver-class-name: com.mysql.jdbc.Driver ?

3.添加SpringSecurity安全框架

因為 Activiti7 與 SpringBoot 整合后，默認情況下，集成了 SpringSecurity 安全框架，這樣我們就要去準備 SpringSecurity 整合進來的相關用戶權限配置信息。

（1）添加SecurityUtil類

@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);} } ?

（2）添加DemoApplicationConfig 類

它的作用是為了實現SpringSecurity 框架的用戶權限的配置，這樣我們就可以在系統中使用用戶權限信息。

@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"},{"system", "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(SimpleGrantedAuthority::new).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();} }

（3）創建測試類

@RunWith(SpringRunner.class) @SpringBootTest public class Actviti7DemoApplicationTests {@Autowiredprivate ProcessRuntime processRuntime;@Autowiredprivate TaskRuntime taskRuntime;@Autowiredprivate SecurityUtil securityUtil; }

（4）查看流程定義信息

activiti7與SpringBoot整合后會自動讀取resources/processes下的所有bpmn流程圖

? ?@Testpublic void contextLoads() {securityUtil.logInAs("salaboy");Page<ProcessDefinition> processDefinitionPage = processRuntime.processDefinitions(Pageable.of(0, 10));System.out.println("可用的流程定義數量：" + processDefinitionPage.getTotalItems());for (ProcessDefinition pd : processDefinitionPage.getContent()) {System.out.println("流程定義：" + pd);}}

（5）啟動流程實例

@Test public void testStartProcess() {securityUtil.logInAs("system");ProcessInstance pi = processRuntime.start(ProcessPayloadBuilder.start().withProcessDefinitionKey("myProcess_1").build());System.out.println("流程實例ID：" + pi.getId()); }

（6）查詢并完成任務

該實例的流程圖中，已經指定兩個步驟的指派的組。我們可以用指定組中的用戶登錄去查詢任務并完成任務。

?

? ?@Testpublic void testTask() {securityUtil.logInAs("ryandawsonuk");Page<Task> taskPage = taskRuntime.tasks(Pageable.of(0, 10));if (taskPage.getTotalItems() > 0) {//遍歷任務列表for (Task task : taskPage.getContent()) {//拾取任務 candidateGroups="activitiTeam"taskRuntime.claim(TaskPayloadBuilder.claim().withTaskId(task.getId()).build());System.out.println("任務：" + task);//執行任務taskRuntime.complete(TaskPayloadBuilder.complete().withTaskId(task.getId()).build());}}Page<Task> taskPage2 = taskRuntime.tasks(Pageable.of(0, 10));if (taskPage2.getTotalItems() > 0) {System.out.println("任務：" + taskPage2.getContent());}}
