javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCExcep tion: could not execute query
提问by Runnerdave
Hi I have researched this in these forums thoroughly and many people have posted stuff but none of that helps me.
嗨，我在这些论坛上对此进行了彻底的研究，很多人都发布了一些东西，但没有一个对我有帮助。
my object:
我的对象：
@Entity
@Table(name = "ADDRESS")
@NamedQuery(name = "Address.findByRegistrationId", query = "SELECT a FROM Address a WHERE a.registration_id = :registration_id")
public class Address {
@Id
@Column(name = "ADDRESS_ID")
@GeneratedValue(strategy = GenerationType.AUTO)
private long address_id;
@Column(name = "REGISTRATION_ID")
private long registration_id;
public long getRegistration_id() {
return registration_id;
}
public void setRegistration_id(long registration_id) {
this.registration_id = registration_id;
}
my repository implementation:
我的存储库实现：
@Repository
public class AddressRepositoryJpa implements AddressRepository {
private final Logger log = Logger.getLogger(AddressRepositoryJpa.class.getName());
@PersistenceContext
private EntityManager entityManager;
@Override
public Address findByID(int id) {
return entityManager.find(Address.class, id);
}
@Override
public Address findByRegistrationID(Long registration_id) {
TypedQuery<Address> query = (TypedQuery<Address>) entityManager.createNamedQuery("Address.findByRegistrationId", Address.class);
query.setParameter("registration_id", registration_id);
Address address = (Address) query.getSingleResult();
return address;
}
my persistence.xml
我的持久性.xml
<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
<property name="username" value="xxxx"/>
<property name="password" value="xxxxx"/>
<property name="url" value="jdbc:oracle:thin:@//xxxxx:1521/XXX.XXX.XXX.XX.XX"/>
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>
</property>
<property name="jpaProperties">
<map><!--validate | update | create | create-drop-->

<entry key="hibernate.show_sql" value="true"/>
<entry key="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
</map>
</property>
<property name="packagesToScan" value="edu.rmit.core.entities"/>
</bean>
<tx:annotation-driven/>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"/>
I have tried named queries and even one without parameters as a list and no luck, I wonder if there is any special configuration I need to do.
我试过命名查询，甚至一个没有参数的查询作为列表，但没有运气，我想知道是否需要做任何特殊的配置。
The entitymanager.find method works, so the connection to the db is fine.
entitymanager.find 方法有效，因此与数据库的连接很好。
Thanks a lot.
非常感谢。

Maybe it's just a matter of improper casing :)
也许这只是大小写不当的问题:)
Named parameters are case-sensitive and may be used by both dynamic and static queries.
命名参数区分大小写，可用于动态和静态查询。
You can easily test it out by using this API instead
javax.persistence.Query#setParameter(int, java.lang.Object)like so:
您可以使用此 API 轻松测试它，
javax.persistence.Query#setParameter(int, java.lang.Object)如下所示：
Query query = entityManager.createNamedQuery("find address by registration_id");
query.setParameter(1, registration_id);
Address address = (Address) query.getSingleResult();
return address;
回答by Runnerdave
I have found what the problem was, in my entity I had another field called "student_id" that was defined in the entity as int but in the database is a varchar.
我发现了问题所在，在我的实体中，我有另一个名为“student_id”的字段，该字段在实体中定义为 int 但在数据库中为 varchar。
So the errors given where not related to the field I was focusing on: "registration_id" but to another one.
所以给出的错误与我关注的领域无关：“registration_id”而是另一个。
Thanks everyone for your answers.
谢谢大家的回答。
回答by Meriton Husaj
try naming your query like this:
尝试像这样命名您的查询：
@NamedQuery(name = "Address.findByRegistrationId")...
