下面列出了怎么用org.springframework.boot.autoconfigure.transaction.PlatformTransactionManagerCustomizer的API类实例代码及写法，或者点击链接到github查看源代码。
@Bean
public PlatformTransactionManagerCustomizer platformTransactionManagerCustomizer(AbstractRoutingDataSource abstractRoutingDataSource){
return transactionManager -> {
DataSourceTransactionManager dataSourceTransactionManager = (DataSourceTransactionManager) transactionManager;
dataSourceTransactionManager.setDataSource(abstractRoutingDataSource);
};
}
