SpringBoot整合Activiti7的实现代码
(编辑:jimmy 日期: 2024/11/16 浏览:3 次 )
Activiti7发布正式版之后,它与SpringBoot2.x已经完全支持整合开发。我们可以将Activiti7与SpringBoot整合开发的坐标引入到工程中,从而达到SpringBoot支持Activti7整合。
1.使用IDEA创建SpringBoot项目
在工程的pom.xml文件中引入相关的依赖,具体依赖如下所示
<"1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.example</groupId> <artifactId>activiti</artifactId> <version>0.0.1-SNAPSHOT</version> <name>activiti</name> <description>Demo project for Spring Boot</description> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring-boot-starter</artifactId> <version>7.0.0.Beta2</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.5</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.27</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
2.application.yml文件配置
为了能够实现Activiti7生成的表放到Mysql数据库中,需要在配置文件application.yml中添加相关的配置
server: port: 8085 spring: application: name: spring-activiti datasource: url: jdbc:mysql://localhost:3306/activiti"color: #ff0000">3.添加SpringSecurity安全框架整合配置
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以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
