javax.persistence.PersistenceException：org.hibernate.exception.GenericJDBCExcep tion：无法执行查询

Question

您好我已经在这些论坛中对此进行了彻底的研究，很多人都发布了这些内容，但这些都没有帮助我。

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;
}

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;
}

我的persistence.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.hbm2ddl.auto" value="update"/>
            <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"/>

我已尝试过命名查询，甚至没有参数作为列表也没有运气，我想知道我是否需要做任何特殊配置。

entitymanager.find方法有效，因此与db的连接很好。

非常感谢。

Answer 1

我发现问题是什么，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但在数据库中是varchar。

所以给出的错误与我所关注的领域无关：“registration_id”，而不是另一个。

感谢大家的回答。

Answer 2

也许这只是一个不正确的套管问题：）

Named Parameters in Queries

  

命名参数区分大小写，可供动态和静态查询使用。

您可以使用此API轻松测试它 javax.persistence.Query#setParameter(int, java.lang.Object)喜欢这样：

Query query = entityManager.createNamedQuery("find address by registration_id");
query.setParameter(1, registration_id);
Address address = (Address) query.getSingleResult();
return address;

Answer 3

尝试命名您的查询：

@NamedQuery(name = "Address.findByRegistrationId")...
