Question

我有一个使用spring / hibernate / jparepository连接到Postgresql 9.3.9 db的应用程序。它执行findAll（）查询，读取整个表（20行...），连接很少。在测试数据库中填充测试数据的服务器上运行完美。在生产数据库中填充生产数据的另一台服务器上，应用程序在执行“select”查询后挂起并开始刻录cpu。如果我在pgadmin3上粘贴相同的查询，它将在22ms内在生产数据库上执行。所以我在想一个java / jdbc / hibernate错误，但我已经在使用最新版本了。

我该如何调试？

Java DAO

public interface SitesRepository extends JpaRepository<Sites, Integer> {
    @EntityGraph(value = "tutto", type = EntityGraphType.LOAD)
    List<Sites> findAll();
}

最后，如果你还等待，junit test会出现内存不足错误（请注意表中有22行）：
