Question

使用findAll()中的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，我的帐户服务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.

我尝试用Spring Data Neo4J repository findAll() results in a nullpointerexception解决问题，所以我在spring-config.xml中添加<tx:annotation-driven mode="proxy"/> 但它并没有解决我的问题。

这里是我的github回购：https://github.com/mzober/springContextWorld/tree/CollectorManager_ErrorBranch

这是我的spring-config.xml：

   xmlns:context="http://www.springframework.org/schema/context"

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

如果我要发布更多代码，请写一条评论。

帮助。

这可能与问题有关：https://jira.spring.io/browse/DATAGRAPH-531。如果是这种情况，则需要更改

service.findAll()

为：

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

...并且回滚异常应该消失。

只有来自GraphRepository＆lt;＆gt;的findAll（）以org.neo4j.graphdb.TransactionFailureException结尾：无法将事务标记为仅回滚
