Java Spring数据JPA更新@Query未更新?
我有一个更新查询:Java Spring数据JPA更新@Query未更新?,java,jpa,spring-data,Java,Jpa,Spring Data,我有一个更新查询: @Modifying @Transactional @Query("UPDATE Admin SET firstname = :firstname, lastname = :lastname, login = :login, superAdmin = :superAdmin, preferenceAdmin = :preferenceAdmin, address = :address, zipCode = :zipCode, city = :city, country =
@Modifying
@Transactional
@Query("UPDATE Admin SET firstname = :firstname, lastname = :lastname, login = :login, superAdmin = :superAdmin, preferenceAdmin = :preferenceAdmin, address = :address, zipCode = :zipCode, city = :city, country = :country, email = :email, profile = :profile, postLoginUrl = :postLoginUrl WHERE id = :id")
public void update(@Param("firstname") String firstname, @Param("lastname") String lastname, @Param("login") String login, @Param("superAdmin") boolean superAdmin, @Param("preferenceAdmin") boolean preferenceAdmin, @Param("address") String address, @Param("zipCode") String zipCode, @Param("city") String city, @Param("country") String country, @Param("email") String email, @Param("profile") String profile, @Param("postLoginUrl") String postLoginUrl, @Param("id") Long id);
我试图在集成测试中使用它:
adminRepository.update("Toto", "LeHeros", admin0.getLogin(), admin0.getSuperAdmin(), admin0.getPreferenceAdmin(), admin0.getAddress(), admin0.getZipCode(), admin0.getCity(), admin0.getCountry(), admin0.getEmail(), admin0.getProfile(), admin0.getPostLoginUrl(), admin0.getId());
Admin loadedAdmin = adminRepository.findOne(admin0.getId());
assertEquals("Toto", loadedAdmin.getFirstname());
assertEquals("LeHeros", loadedAdmin.getLastname());
但是字段没有更新并保留其初始值,因此测试失败
我尝试在findOne查询之前添加刷新:
adminRepository.flush();
但失败的断言仍然相同
我可以在日志中看到update sql语句:
update admin set firstname='Toto', lastname='LeHeros', login='stephane', super_admin=0, preference_admin=0,
address=NULL, zip_code=NULL, city=NULL, country=NULL, email='stephane@thalasoft.com', profile=NULL,
post_login_url=NULL where id=2839
但是日志中没有显示与查找器相关的sql:
Admin loadedAdmin = adminRepository.findOne(admin0.getId());
The finder sql statement is not making its way to the database.
是否由于某些缓存原因而忽略了它
如果我随后向findByEmail和findByLogin查找程序添加调用,如中所示:
adminRepository.update("Toto", "LeHeros", "qwerty", admin0.getSuperAdmin(), admin0.getPreferenceAdmin(), admin0.getAddress(), admin0.getZipCode(), admin0.getCity(), admin0.getCountry(), admin0.getEmail(), admin0.getProfile(), admin0.getPostLoginUrl(), admin0.getId());
Admin loadedAdmin = adminRepository.findOne(admin0.getId());
Admin myadmin = adminRepository.findByEmail(admin0.getEmail());
Admin anadmin = adminRepository.findByLogin("qwerty");
assertEquals("Toto", anadmin.getFirstname());
assertEquals("Toto", myadmin.getFirstname());
assertEquals("Toto", loadedAdmin.getFirstname());
assertEquals("LeHeros", loadedAdmin.getLastname());
然后我可以在日志中看到正在生成的sql语句:
但是断言:
assertEquals("Toto", myadmin.getFirstname());
即使跟踪显示检索到相同的域对象,仍然会失败:
TRACE [BasicExtractor] found [1037] as column [id14_]
另一件让我对另一个查找程序感到困惑的事情是,它显示了一个limit 2子句,尽管它应该只返回一个Admin对象
我认为在返回一个域对象时总是有一个限制1。这是对Spring数据的错误假设吗
粘贴到MySQL客户端时,控制台日志中显示的sql语句,逻辑工作正常:

用于验证todo条目标题是否已更新的DbUnit数据集的名称称为toDoData-update.xml,其内容如下所示(出于某种原因,todo条目的版本未更新,但标题已更新。了解原因吗?)
运行集成测试后,测试通过,todo条目的标题更新。我遇到的唯一问题是版本字段没有更新。你知道为什么吗
我不理解这种描述有点模糊。如果您想获得有关为Spring数据JPA存储库编写集成测试的更多信息,可以阅读。我终于明白了发生了什么 在保存对象的语句上创建集成测试时,建议刷新实体管理器,以避免任何误判,即避免测试运行正常,但在生产环境中运行时其操作将失败。事实上,测试可以正常运行,因为一级缓存没有刷新,也没有写入到数据库中。为了避免这种假阴性集成测试,请在测试体中使用显式刷新。请注意,生产代码不应该需要使用任何显式刷新,因为ORM的角色是决定何时刷新 在update语句上创建集成测试时,可能需要清除实体管理器,以便重新加载一级缓存。实际上,update语句完全绕过一级缓存,直接写入数据库。第一级缓存随后不同步,并反映更新对象的旧值。要避免对象的这种陈旧状态,请在测试主体中使用显式清除。请注意,生产代码永远不需要使用任何显式清除,因为ORM的角色是决定何时清除
我的测试现在运行正常。默认情况下,EntityManager不会自动刷新更改。您应该在查询语句中使用以下选项:
@Modifying(clearAutomatically = true)
@Query("update RssFeedEntry feedEntry set feedEntry.read =:isRead where feedEntry.id =:entryId")
void markEntryAsRead(@Param("entryId") Long rssFeedEntryId, @Param("isRead") boolean isRead);
我遇到了同样的问题,我试图执行一个更新查询,就像你做的一样-
@Modifying
@Transactional
@Query(value = "UPDATE SAMPLE_TABLE st SET st.status=:flag WHERE se.referenceNo in :ids")
public int updateStatus(@Param("flag")String flag, @Param("ids")List<String> references);
修改
@交易的
@查询(value=“updatesample\u TABLE st SET st.status=:标志,其中se.referenceNo位于:id”)
public int updateStatus(@Param(“flag”)字符串标志,@Param(“ids”)列表引用);
如果在主类上放置了@EnableTransactionManagement
注释,则这将起作用。
Spring 3.1引入了
@EnableTransactionManagement
注释,将在@Configuration
类中使用,并启用事务支持。这里的根本问题是JPA的一级缓存。
来自JPA规范2.2版第3.1节。我强调:
EntityManager实例与持久性上下文关联。持久性上下文是一组实体实例,其中对于任何持久性实体标识,都有一个唯一的实体实例
这很重要,因为JPA跟踪对该实体的更改,以便将其刷新到数据库中。
作为一个副作用,它还意味着在单个持久性上下文中,实体只加载一次。
这就是为什么重新加载更改的实体没有任何效果
您有两个选择如何处理此问题:
EntityManager
中逐出实体。
这可以通过调用、用@modify(clearAutomatically=true)
注释更新方法来完成,该方法会逐出所有实体。
确保先刷新对这些实体的更改,否则可能会丢失更改@Transactional
注释的bean调用的bean上使用@Transactional
注释单独的方法来实现。
另一种方法是使用特别有效的
