Question

以下集成测试方法testLocalPaging使用HSQL内存数据库，Stock表中有100个条目。存储库类是使用Spring Data JPA实现的，它只是一个扩展PagingAndSortingRepository的接口。但是，当页数设置为大约15或更低时，测试将在第六页“冻结”。我意识到从数据库中读取大约6页后测试将停滞不前。但是，如果我使用更大的页面大小，例如20，则测试运行得很好，在五页之后从数据库读取的所有100个条目都没有问题。我想知道Spring Data JPA是否存在错误？我注意到导致问题的那一行在org.springframework.aop.framework.JdkDynamicAopProxy的第202行。我正在使用spring-data-jpa-1.4.1.RELEASE，spring-aop-3.1.4.RELEASE和hibernate-core-3.6.10.Final等。有人可以指出我的测试中是否有问题或Spring或Hibernate中的错误？我对测试结果感到很困惑。

StockDaoJpa：

import org.springframework.data.repository.PagingAndSortingRepository;

public interface StockDaoJpa extends PagingAndSortingRepository<Stock, Long>{
}

测试方法：

@Test
public void testLocalPaging()
{
    log.info("testLocalPaging()...");
    int size = 10;
    Page<Stock> page = null;
    Pageable request = new PageRequest(0, size, new Sort(new Order("StockId")));
    do
    {
        if(page == null)
            page = stockRepository.findAll(request);
        else
        {
            request = page.nextPageable();
            log.info(request);
            //TODO: It freezes at the sixth request whatever the pagesize is.
            page = stockRepository.findAll(request);
        }
        log.info(page);
        for(Stock s : page)
            log.info(String.format("Id = %s", s.getStockId()));
        log.info(page.hasNextPage());
    } while(page.hasNextPage());
}

JdkDynamicAopProxy类中的代码，测试卡在：

...
            else {
                // We need to create a method invocation...
                invocation = new ReflectiveMethodInvocation(proxy, target, method, args, targetClass, chain);
                // Proceed to the joinpoint through the interceptor chain.
                retVal = invocation.proceed();
            }
...

从testLocalPaing输出：

Answer 1

事实证明，带有spring-data-jpa-1.4.1.RELEASE的hibernate-core-3.6.10.Final导致了这个问题。我改为hibernate-core-4.2.7.Final，问题自动消失。

在Spring Data JPA中的Pageable，PageRequest或Spring中的JdkDynamicAopProxy是否存在错误？
