spring-transactions

问题 I've recently begun using Spring's Data Source Transaction Manager. I have a problem now. My transaction includes updates to a DB table and a write operation to a file. It works fine but I have some doubts about file I/O. As you see below, I have configured openFile and closeFile methods of my bean as the init-method and the destroy-method respectively, which in turn provides those methods to be called just like a constuructor and a destructor. If the file is not closed properly, some of the

问题 I have something like this: @Service @Transactional public class ServiceA { @Autowired SomeDAO1 dao1; @Autowired ServiceB serviceB; public void methodServiceA() { serviceB.someMethodThatRunsInsertIntoDB(); dao1.anotherMethodThatRunsInsertIntoDB(); } } @Service @Transactional public class ServiceB { @Autowired Dao2 dao2; public void someMethodThatRunsInsertIntoDB() { dao2.insertXXX(); } } My problem is: if serviceB.someMethodThatRunsInsertIntoDB() executes sucessfully but dao1

问题 I have a below spring setup. Basically I am trying to configure two transaction managers here. One with hibernate and other with JPA. But somehow when I try to run JPA transaction manager, there I get "javax.persistence.TransactionRequiredException: No transactional EntityManager available" error. Appreciate if somebody finds the problem in below code. data-context.xml file as below <bean id="fundBO" class="org.springframework.aop.framework.ProxyFactoryBean"> <property name="proxyInterfaces"

问题 I am using JPA with Spring. I am trying to do batch import. If there is problem with batch import then I would like to insert individually, and if this fails also then I would like to save to duplicates table. I wrote a logic for this but I get this error everytime: Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Transaction marked as rollbackOnly Mine setting for JPA are like this: @Bean(name = "dataSource", destroyMethod = "") public DataSource

问题 Whenever I try to entityManager.flush() I get the error mentioned on title. That is interesting that all my models have been created properly on MySql during application start up. I have read several questions with similar exception and basically all of them point to use/change @Transaction somehow. Any suggestion or even a scratch idea about what to check will be highly appreciated. I don't think it is really relevant but let me inform btw: I am using WebSphere Liberty Profile + MySql. where

问题 I have started using spring from last few months and I have a question on transactions. I have a java method inside my spring batch job which first does a select operation to get first 100 rows with status as 'NOT COMPLETED' and does a update on the selected rows to change the status to 'IN PROGRESS'. Since I'm processing around 10 million records, I want to run multiple instances of my batch job and each instance has multiple threads. For a single instance, to make sure two threads are not

问题 I have a code where event is published in a method annotated with Spring @Transactional annotation. @Override @Transactional public Task updateStatus(Integer taskId, ExecutionStatus newStatus) { Task task = Task.builder().executionStatus(newStatus).build(); return updateStatusInternal(taskId, rteWithMetadata); } private TaskExecution updateStatusInternal(Integer taskId, Task newStatus) { Task task = taskService.findById(taskId); TaskExecution te = task.getFirstExecution(); TaskExecution
