Camunda是一个工作流引擎,可以与数据库进行集成。如果你想要在Spring Boot应用程序中配置多个数据库,则可以使用多数据源配置。
首先,你需要创建两个数据源,分别配置与两个不同的数据库连接。然后,通过将Camunda的ProcessEngineConfiguration设置为使用特定的数据源来控制Camunda使用哪个数据库。
这是一个例子的代码:
@Configuration public class CamundaDataSourceConfig { @Bean @Primary @ConfigurationProperties(prefix = "spring.datasource.primary") public DataSource primaryDataSource() { return DataSourceBuilder.create().build();
@Bean @ConfigurationProperties(prefix = "spring.datasource.secondary") public DataSource secondaryDataSource() { return DataSourceBuilder.create().build();
@Bean public ProcessEngineFactoryBean processEngine(DataSource primaryDataSource, DataSource secondaryDataSource) { ProcessEngineFactoryBean factoryBean = new ProcessEngineFactoryBean(); factoryBean.setProcessEngineConfiguration( createProcessEngineConfig(primaryDataSource, secondaryDataSource)); return factoryBean;
private SpringProcessEngineConfiguration createProcessEngineConfig(DataSource primaryDataSource, DataSource secondaryDataSource) { // Configure which data source to use for Camunda SpringProcessEngineConfiguration processEngineConfig = new SpringProcessEngineConfiguration(); processEngineConfig.setDataSource(primaryDataSource); processEngineConfig.setDbIdentityUsed(false); processEngineConfig.setJobExecutorActivate(false); processEngineConfig.setMetricsEnabled(false); processEngineConfig.setTransactionManager(new DataSourceTransactionManager(primaryDataSource));
// Add an additional data source for your custom queries
processEngineConfig.getAdditionalDataSources().put("secondaryDataSource", secondaryDataSource);
return processEngineConfig;
这样,你就可以在Camunda中使用两个不同的数据库了。
