如何使用JPA和Spring Data执行存储过程?
2022-09-03 07:06:55
我正在尝试调用数据库中的存储过程,但不断收到以下异常:Terminal_GetTicket
PropertyReferenceException: No property getTicket found for type TicketInfo
我已经用一个非常简单的测试实体交叉验证了我的配置,一切似乎都运行良好,但是对于实际情况,有些地方不对劲。
这是我的域实体 ():TicketInfo
@Entity
@NamedStoredProcedureQuery(name = "TicketInfo.getTicket", procedureName = "Terminal_GetTicket", resultClasses = TicketInfo.class, parameters = {
@StoredProcedureParameter(mode = ParameterMode.IN, name = "sys_id_game", type = Integer.class)})
public class TicketInfo {
@Id @GeneratedValue
private Long id;
private String idTicket;
private Integer externalTicketCode;
private Short sequenseAlert;
private Integer dlTimeStamp;
所有实例变量都正确定义了其 getter 和 setter,并且存储过程总共有 5 个输出参数与 的属性匹配。TicketInfo
此外,这是我的存储库接口:
public interface TicketInfoRepository extends CrudRepository<TicketInfo, Long> {
@Transactional(timeout = 5)
@Procedure
TicketInfo getTicket(Integer sys_id_game);
}
另外,这是我的文件(春季):context.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:jpa="http://www.springframework.org/schema/data/jpa"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<context:component-scan base-package="ar.com.boldt.godzilla" />
<jpa:repositories base-package="xx.xxx.xxx.godzilla.business.dao" />
<bean id="jpaVendorAdapter"
class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="${dataSource.show.sql}" />
<property name="generateDdl" value="false" />
<property name="database" value="SQL_SERVER" />
</bean>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
<!-- spring based scanning for entity classes -->
<property name="packagesToScan" value="xx.xxx.xxx.godzilla.business.dao" />
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager" />
<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
<property name="cacheManager" ref="ehcache" />
</bean>
<bean id="ehcache"
class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<property name="configLocation" value="classpath:ehcache.xml" />
</bean>
</beans>
最后是存储过程本身的淡化版本:
ALTER PROCEDURE [Terminal_GetTicket](
@arg int
,@res int output
,@res2 int output
)
as
Declare @error int
select 0, 1, 2
RETURN @error
现在,每当我尝试设置注释时,我都会遇到上面提到的异常。@Autowired
