Question

我需要hibernate在启动junit测试之前读取一个sql文件，所以我在persistence.xml中进行了以下配置：

<persistence xmlns="http://java.sun.com/xml/ns/persistence" 
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" 
         xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 
                             http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

<persistence-unit name="test" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="hibernate.connection.username" value="sa" />
        <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver" />
        <property name="hibernate.connection.password" value="" />
        <property name="hibernate.connection.url" value="jdbc:hsqldb:hsql://localhost:9001/test" /> 
        <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect" />
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.format_sql" value="true" />
        <property name="hibernate.id.new_generator_mappings" value="true" />
        <property name="hibernate.hbm2ddl.auto" value="create" />
        <property name="hibernate.hbm2ddl.import_files" value="/META-INF/load.sql" />
    </properties>
</persistence-unit>
</persistence>

用于加载spring上下文的applicationContext.xml：

<?xml version="1.0" encoding="UTF-8"?>
<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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">

<context:component-scan base-package="com.test" />

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
    <property name="persistenceUnitName" value="test" />
</bean>

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

<tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>

<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"></bean>
</beans>

Junit测试扩展了课程：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:/applicationContext.xml" })
@TestExecutionListeners(inheritListeners = false, listeners = {
    TransactionalTestExecutionListener.class, DependencyInjectionTestExecutionListener.class })
@TransactionConfiguration(defaultRollback = true)
@Transactional
public abstract class UnitTestConfiguration {}

当我运行junit测试时，没有导入文件load.sql，也没有显示错误。我正在使用Hibernate 4和Spring 3.0.5。

Answer 1

我将load.sql放在src/test/resource/文件夹中解决了我的问题。这种方式不需要在persistence.xml中指定sql文件。

Answer 2

我认为（我通常使用它）你应该将它包含在applicationContext.xml中：

<import resource="classpath:/path_to_persistence/persistence.xml" />

您还可以在测试@ContextConfiguration中指定多个配置文件：

@ContextConfiguration(locations = { "classpath:/applicationContext1.xml", ... ,"classpath:/applicationContextn.xml" })

Answer 3

只需将名称为import.sql的文件放在src/test/resources目录中即可。

属性javax.persistence.hibernate.hbm2ddl.import_files的默认值为 import.sql。

检查：http://docs.jboss.org/hibernate/orm/5.3/userguide/html_single/Hibernate_User_Guide.html

persistence.xml中的hibernate.hbm2ddl.import_files不起作用
