@ andy- wilkinson给出了答案，但这是如何使用它的示例。根据您的建议，创建另一个DataSource，然后将其连接到SpringProcessEngineConfiguration。像这样：
@Configuration
public class ActivitiConfiguration extends AbstractProcessEngineAutoConfiguration {
@Bean
@ConfigurationProperties(prefix = "datasource.activiti")
public DataSource activitiDataSource() {
return DataSourceBuilder
.create()
.url("jdbc:h2:mem:activiti")
.username("activiti")
.driverClassName("org.h2.Driver")
.build();
}
@Bean
public SpringProcessEngineConfiguration springProcessEngineConfiguration(
PlatformTransactionManager transactionManager,
SpringAsyncExecutor springAsyncExecutor) throws IOException {
return baseSpringProcessEngineConfiguration(
activitiDataSource(),
transactionManager,
springAsyncExecutor);
}
}
Activiti将用于activitiDataSource创建其表并保留其数据。
现在，您可以创建另一个DataSource来携带应用程序表和数据。这是基于的基本示例spring-boot-sample- basic。基本上，它customerId在WaiterEntity/中保留a WaiterRepository（使用Spring Data JPA-为简洁起见，然后将其保留）传递到Activiti basic2.bpmn进程，该进程仅将其打印出到控制台。
@SpringBootApplication
public class Application {
@Bean
@Primary
@ConfigurationProperties(prefix = "datasource.primary")
public DataSource primaryDataSource() {
return DataSourceBuilder
.create()
.url("jdbc:h2:mem:primary")
.username("primary")
.driverClassName("org.h2.Driver")
.build();
}
@Bean
CommandLineRunner basics(final RuntimeService runtimeService,
final WaiterRepository repository) {
return new CommandLineRunner() {
@Override
public void run(String... strings) throws Exception {
runtimeService.startProcessInstanceByKey(
"waiter2",
Collections.singletonMap(
"customerId",
(Object) repository.save(new WaiterEntity(123L)).getCustomerId()));
}
};
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
注意@Primary上primaryDataSource。如果您省略该WAITER_ENTITY表，则将在中创建表activitiDataSource（没有任何其他特定配置）。
