场景

项目资料库使用oceanbase-mysql版本，flowable启动时提示Caused by: org.flowable.common.engine.api.FlowableException: couldn't deduct database type from database product name 'OceanBase'

解决

使用自定义ProcessEngine对象

@Configuration
public class FlowableConfig {

    @Resource
    private HikariDataSource dataSource;

    @Bean
    public ProcessEngine getProcessEngine(PlatformTransactionManager transactionManager) {
        SpringProcessEngineConfiguration configuration = new SpringProcessEngineConfiguration();
        configuration.setTransactionManager(transactionManager);
        configuration.setDataSource(dataSource);//使用项目使用的数据源HikariDataSource
        configuration.setDatabaseSchemaUpdate("true");
        configuration.setDatabaseType("mysql");//关键设置，设置数据库类型为mysql
        return configuration.buildProcessEngine();
    }
}
