springboot集成flowable

Spring Boot 集成 Flowable 的过程很简单，可以通过以下步骤来实现：

1. 在 pom.xml 文件中添加 Flowable 依赖。

<dependency>
  <groupId>org.flowable</groupId>
  <artifactId>flowable-spring-boot-starter-process</artifactId>
  <version>6.5.0</version>
</dependency>

2. 在 application.properties 文件中配置 Flowable 数据源。

spring.datasource.url=jdbc:h2:mem:flowable
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver

3. 创建 Flowable 的配置类。

@Configuration
@AutoConfigureAfter({ DataSourceAutoConfiguration.class, FlywayAutoConfiguration.class })
public class FlowableConfig {

    @Autowired
    private DataSource dataSource;

    @Bean
    public SpringProcessEngineConfiguration springProcessEngineConfiguration(
            PlatformTransactionManager transactionManager,
            SpringAsyncExecutor springAsyncExecutor) {

        SpringProcessEngineConfiguration configuration = new SpringProcessEngineConfiguration();

        configuration.setDataSource(dataSource);
        configuration.setDatabaseSchemaUpdate("true");
        configuration.setAsyncExecutorEnabled(true);
        configuration.setAsyncExecutor(springAsyncExecutor);
        configuration.setTransactionManager(transactionManager);

        return configuration;
    }

    @Bean
    public ProcessEngine processEngine(
            SpringProcessEngineConfiguration springProcessEngineConfiguration) {
        return springProcessEngineConfiguration.buildProcessEngine();
    }

    @Bean
    public RepositoryService repositoryService(ProcessEngine processEngine) {
        return processEngine.getRepositoryService();
    }

    @Bean
    public RuntimeService runtimeService(ProcessEngine processEngine) {
        return processEngine.getRuntimeService();
    }

    @Bean
    public TaskService taskService(ProcessEngine processEngine) {
        return processEngine.getTaskService();
    }

    @Bean
    public HistoryService historyService(ProcessEngine processEngine) {
        return processEngine.getHistoryService();
    }

    @Bean
    public ManagementService managementService(ProcessEngine processEngine) {
        return processEngine.getManagementService();
    }

    @Bean
    public FormService formService(ProcessEngine processEngine) {
        return processEngine.getFormService();
    }

    @Bean
    public IdentityService identityService(ProcessEngine processEngine) {
        return processEngine.getIdentityService();
    }

}

4. 在启动类上添加 @EnableProcessEngine 和 @Import(FlowableConfig.class) 注解。
