关于这个问题有好几篇帖子,但仍然没有找到答案。这是父类Userr。在@OneToMany关系中,我想删除一个特定的子帐户。
现在,当我通过“删除”查询执行此操作时,我得到以下异常。
组织。springframework。刀。InvalidDataAccessApiUsageException:执行更新/删除查询;嵌套的异常是javax。坚持不懈TransactionRequiredException:执行更新/删除查询
@RooJavaBean
@RooToString
@RooJpaEntity
@RooJpaActiveRecord(finders = { "findUserrsByUserName"})
public class Userr {
@NotNull
@Column(unique = true)
private String userName;
@NotNull
private int userType;
@OneToMany(mappedBy = "user", fetch = FetchType.LAZY, cascade = CascadeType.ALL, orphanRemoval = true)
private List<Account> accounts = new ArrayList<Account>();
}
儿童班
@RooJavaBean
@RooToString
@RooJpaActiveRecord
@RooJpaEntity
public class Account {
@OneToMany(mappedBy="account", fetch=FetchType.LAZY, cascade = CascadeType.ALL)
List<Message> messages = new ArrayList<Message>();
/*@OneToMany(mappedBy="account", fetch=FetchType.LAZY, cascade = CascadeType.ALL)
List<PremiumPlayPositionCombination> premiumPlayPosition = new ArrayList<PremiumPlayPositionCombination>();*/
@OneToMany(mappedBy="account", fetch=FetchType.LAZY, cascade = CascadeType.ALL)
List<PositionCombinationArc> allPositionsArc = new ArrayList<PositionCombinationArc>();
@ManyToOne
@JoinColumn(name="user_id")
private Userr user;
}
这是我的删除查询
@Transactional
public static void deleteClientByClientId(Long clientId) {
System.out.println("Delete query findUsersClientsByUser" + clientId);
int deleteCount= entityManager().createQuery("DELETE FROM Account where id =:clientId").setParameter("clientId", clientId).executeUpdate();
System.out.println("Delete query findUsersClientsByUser" + deleteCount);
}
我在ApplicationContext中添加了安全性。像这样的xml
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

Turn on AspectJ @Configurable support. As a result, any time you
instantiate an object, Spring will attempt to perform dependency
injection on that object. This occurs for instantiation via the "new"
keyword, as well as via reflection. This is possible because AspectJ
is used to "weave" Roo-based applications at compile time. In effect
this feature allows dependency injection of any object at all in your
system, which is a very useful feature (without @Configurable you'd
only be able to dependency inject objects acquired from Spring or
subsequently presented to a specific Spring dependency injection
method). Roo applications use this useful feature in a number of
areas, such as @PersistenceContext injection into entities.

This declaration will cause Spring to locate every @Component,
@Repository and @Service in your application. In practical terms this
allows you to write a POJO and then simply annotate the new POJO as an
@Service and Spring will automatically detect, instantiate and
dependency inject your service at startup time. Importantly, you can
then also have your new service injected into any other class that
requires it simply by declaring a field for your service inside the
relying class and Spring will inject it. Note that two exclude filters
are declared. The first ensures that Spring doesn't spend time
introspecting Roo-specific ITD aspects. The second ensures Roo doesn't
instantiate your @Controller classes, as these should be instantiated
by a web tier application context. Refer to web.xml for more details
about the web tier application context setup services.
Furthermore, this turns on @Autowired, @PostConstruct etc support. These
annotations allow you to use common Spring and Java Enterprise Edition
annotations in your classes without needing to do any special configuration.
The most commonly used annotation is @Autowired, which instructs Spring to
dependency inject an object into your class.

当尝试使用HiberNate更新/删除时,最好使用一个事务初始化()和提交()示例来包围查询:
EntityTransaction tr=em.getTransaction();
tr.begin();
Query query = (Query) em.createQuery( "update etudiant set email= :em, adresse= :adr,telephone= :tele,password= :pwd"
+ " where email= :mail");
query.setParameter("em", email)
.setParameter("adr", adresse)
.setParameter("tele", tele)
.setParameter("pwd", pass)
.setParameter("mail", ancienEmail);
int a= query.executeUpdate();
tr.commit();
在Spring上下文文件中,您需要添加以下代码:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
<tx:annotation-driven />
另外,添加您的Spring Security
bean配置。
您可以在代码中检查以下内容:
