Question

我们在tomcat上运行了一个Web应用程序，并且具有如下代码来查找模式实体。

@Override
public Schema findSchemaByCategoryAndDomainId(String category, Integer domainId) throws Exception
{
    return schemaDao.findByCategoryAndDomainId(category, domainId);
}

我们使用的数据库和ORM如下

DataBase: PostgreSQL v9.4 (Windows version)
OpenJPA: version 2.2.2
SpringDataJPA: version 1.3.0.RELEASE

它在开始时工作正常，但经过大量查询后，在4小时内大约112000次，它就会失败并抛出异常，如下所示：

我们已经在调试模式下调试它，它看起来像参数字符串类别和整数domainId都是正确的。在我们重新启动tomcat之后，它再次正常工作。这是JPA问题还是我们需要调整JPA或数据库设置？

将spring-data-jpa lib升级到版本1.9.0.RELEASE或更高版本后，问题就解决了。 8次异步多线程查询测试每次200毫秒。
