java - 仅 GraphRepository<> 中的 findAll() 以 org.neo4j.graphdb.TransactionFailureException : Failed to mark transaction as rollback only 结尾

Question

通过使用 findAll()来自GraphRepository<Account> :

    context = new ClassPathXmlApplicationContext("spring/spring-config.xml");
    accountService = (AccountService) context.getBean("accountService");

    //getAll(){return accountRepository.findAll()}

    accountService.getAll().forEach(account -> System.out.println(account));

(顺便说一句。我的 accountService 中的所有其他功能都有效)

我收到此错误:

 Exception in thread "main" org.neo4j.graphdb.TransactionFailureException: 
 Failed to mark transaction as rollback only.

我尝试通过以下方式解决问题:Spring Data Neo4J repository findAll() results in a nullpointerexception , 所以我添加<tx:annotation-driven mode="proxy"/>在我的 spring-config.xml 中 但这并不能解决我的问题。

这是我的 github 存储库:https://github.com/mzober/springContextWorld/tree/CollectorManager_ErrorBranch

这是我的 spring-config.xml:

<tx:annotation-driven mode="proxy"/>

如果我应该发布更多代码，请写评论。

感谢您的帮助。

这可能与以下问题有关:https://jira.spring.io/browse/DATAGRAPH-531 。如果是这样的话，你需要改变

service.findAll()

至:

service.findAll().as(Collection.class)

...回滚异常应该消失。
