spring-transactions

问题 I have a Spring MVC app with all logic related to a single business concern within a single Java package (controller, service, repository, DTO and resource).

However, the repository shall also be @Transactional , and using Spring

问题 I'm trying to move away from manually-managed transactions to annotation based transactions in my Neo4j application. I've prepared annotation-based Spring configuration file: @Configuration @EnableNeo4jRepositories("xxx.yyy.neo4jplanetspersistence.repositories") @ComponentScan(basePackages = "xxx.yyy") @EnableTransactionManagement public class SpringDataConfiguration extends Neo4jConfiguration implements TransactionManagementConfigurer{ public SpringDataConfiguration() { super();

问题 I'm writing a transactional junit-based IT test for Spring Data JPA repository. To check number of rows in table I use side JDBCTemplate. I notice, that in transactional context invoking of org.springframework.data.repository.CrudRepository#save(S) doesn't take effect.

But If I invoke org.springframework.data.repository.CrudRepository#count after the save(S) then SQL insert is performed and number of rows is increased. I

问题 When using the Transaction() attribute on a method the default isolation level is ReadCommitted. What I want to do is set the default isolation level to ReadUncommitted in the Spring.NET config ( so as not to modify all the Transaction attribute definitions that exist currently) How do I do it ? Can it be done with Spring.NET 1.2 ? I've tried to follow the documentation using tx:advice etc to no avail.

问题 I use annotations to mark methods which should be executed in a transaction. But, in one place I need to do transactionManager.rollback() manually, without annotation. How can I obtain transactionManager object? 回答1: If you want to rollback the current transaction, you may use TransactionAspectSupport.currentTransactionStatus().setRollbackOnly(); Note that it doesn't rollback the transaction immediately - it sets the "rollback only" status, so transaction will be rolled back during attempt to

问题 I don't want the SimpleMessageListenerContainer to continuously consume the messages when my Transaction marked as rollback. I didn't add listener-container in my configuration file and trying to rethrow the AmqpRejectAndDontRequeueException . It is not working.
