Flowable 配置单独数据库

环境

Spring Boot 3、Flowable 7。

代码

yaml 配置

flowable:
  datasource:
    url: jdbc:postgresql://localhost:5432/flowable
    driver-class-name: org.postgresql.Driver
    username: postgres
    password: 123456

数据源配置

实现EngineConfigurator。

@Component
public class DatasourceConfigurator implements EngineConfigurator {

    @Value("${flowable.datasource.url}")
    private String url;

    @Value("${flowable.datasource.driver-class-name}")
    private String driverClassName;

    @Value("${flowable.datasource.username}")
    private String username;

    @Value("${flowable.datasource.password}")
    private String password;

    @Override
    public void beforeInit(AbstractEngineConfiguration engineConfiguration) {
        DataSource dataSource = DataSourceBuilder.create()
                .driverClassName(driverClassName)
                .url(url)
                .username(username)
                .password(password).build();
        engineConfiguration.setDataSource(dataSource);
    }

    @Override
    public void configure(AbstractEngineConfiguration engineConfiguration) {
    }

    @Override
    public int getPriority() {
        return 100000;
    }

}

实现EngineConfigurationConfigurer，泛型为SpringProcessEngineConfiguration。

@Configuration
public class ProcessEngineConfig implements EngineConfigurationConfigurer<SpringProcessEngineConfiguration> {

    private DatasourceConfigurator datasourceConfigurator;

    @Autowired
    public void setDatasourceConfigurator(DatasourceConfigurator datasourceConfigurator) {
        this.datasourceConfigurator = datasourceConfigurator;
    }

    @Override
    public void configure(SpringProcessEngineConfiguration engineConfiguration) {
        engineConfiguration.addConfigurator(datasourceConfigurator);
    }

}
