Question

我现在正在谷歌搜索2天，但我无法找到适合我的问题的答案： - ）。

我尝试使用Spring Data JPA Repositories findAll()函数来使用分页。

我在版本＆＃34; 1.7.1.RELEASE＆＃34;中使用Spring-Data-JPA。后端SQL是MS-SQL 2008服务器，我在版本＆＃34; 1.3.1＆＃34;中使用JTDS。

我创建了一个JPA实体并使用例如findOne方法查询数据库工作正常并给出了预期的答案但是当我使用findAll(Pageable arg0)方法时，抛出了以下的栈跟踪：

我的VendorAdapterConfig看起来像

<bean id="jpaVendor"
    class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
    <property name="showSql" value="true" />
    <property name="generateDdl" value="false" />
    <property name="databasePlatform" value="org.hibernate.dialect.SQLServer2008Dialect" />
    <property name="database" value="SQL_SERVER" />
</bean>

以下是使用findAll方法的代码块（stacktrace中所述的第51行）：

Page<Workrelationship> wrPage = wrRepo.findAll(new PageRequest(0, 20));

任何想法我做错了什么？

谢谢和亲切的问候

Shelltux

PS：我也使用具有相同错误的MS-JDBC驱动程序对其进行了测试

[更新]

以下是生成的查询：

select workrelati0_.a as aR1_9_, workrelati0_.b as b2_9_, workrelati0_.c as c6_9_, workrelati0_.d as d7_9_, workrelati0_.e as e3_9_, workrelati0_.f as f4_9_, workrelati0_.g as gO5_9_ from tblWorkRelationship workrelati0_ limit ?

如果我直接使用MS-SQL Studio执行该查询，则收到相同的错误语法不正确接近＆＃39;限制＆＃39;。

我没有persistence.xml或任何其他hibernate配置。所有这些都是使用Spring-Data Configbeans完成的：

[UPDATE2]

我使用supportsLimit-Function测试了方言，结果意外。如上所述，我使用的是MS-SQL 2008服务器，从MS-SQL 2012开始支持limit-Function。

SQLServerDialect，以及SQLServer2005Dialect以及SQLServer2008Dialect通过调用supportLimit返回true。

SQLServerDialect dialect = new SQLServerDialect();
log.info("Support limit: " + dialect.supportsLimit());

SQLServer2005Dialect dialect2005 = new SQLServer2005Dialect();
log.info("Support limit: " + dialect2005.supportsLimit());

SQLServer2008Dialect dialect2008 = new SQLServer2008Dialect();
log.info("Support limit: " + dialect2008.supportsLimit());

2015-01-26 13:52:38,594  INFO | HHH000400: Using dialect: org.hibernate.dialect.SQLServerDialect

[/ UPDATE2]

[UPDATE3]

这是输出，包括getLimitString：

对我来说是正确的： - ）。

[/ UPDATE3]

Answer 1

我也使用了2个实体管理器，但我已经将一个（MySQL）的数据库方言复制并粘贴到另一个（SQLServer）并且遇到了同样的问题。这篇文章很棒，因为我检查了我的数据库方言，确定它不正确。一旦纠正，它就有效了！

properties.setProperty("hibernate.dialect", "org.hibernate.dialect.SQLServer2012Dialect");

Answer 2

感谢您的评论。我发现了错误： - ）

这是我的错。我正在使用两个带JPA的Transaction-Managers。一个用于应用程序后端SQL，另一个用于嵌入式数据库。所以我不得不配置两个Spring HibernateJpaVendorAdapter Beans，故障是我给了两个相同的名称，因此应用程序后端的那个被嵌入式数据库覆盖了。

谢谢和问候

Answer 3

对于后代：这为我解决了这个问题：

在application.yml中：

datasources:
    thisIsTheDatasourceName:
         dialect: org.hibernate.dialect.SQLServer2012Dialect

Spring-Data-JPA抛出“引起：java.sql.SQLException：'limit'附近的语法不正确。”通过使用findAll
