讓HSQL數據庫在LightAdmin（Spring/JPA/Hibernate）中持久化

Question

我在嘗試更改使用內存中HSQL數據庫的默認LightAdmin設置來使用文件HSQL數據庫。

的persistence.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"> 
    <persistence-unit name="DEMO" transaction-type="RESOURCE_LOCAL"> 
     <provider>org.hibernate.ejb.HibernatePersistence</provider> 
     <class>org.lightadmin.demo.model.Address</class> 
     <class>org.lightadmin.demo.model.Customer</class> 
     <class>org.lightadmin.demo.model.EmailAddress</class> 
     <class>org.lightadmin.demo.model.Product</class> 
     <class>org.lightadmin.demo.model.Order</class> 
     <class>org.lightadmin.demo.model.LineItem</class> 
     <class>org.lightadmin.demo.model.DiscountProgram</class> 
    </persistence-unit> 
</persistence> 

彈簧的context.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xmlns:jdbc="http://www.springframework.org/schema/jdbc" 
     xmlns:context="http://www.springframework.org/schema/context" 
     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
      http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> 

    <context:component-scan base-package="org.lightadmin.demo.service"/> 

    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" 
      p:persistenceUnitName="DEMO" p:dataSource-ref="dataSource"> 
     <property name="jpaVendorAdapter"> 
      <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> 
       <property name="generateDdl" value="true"/> 
       <property name="database" value="HSQL"/> 
      </bean> 
     </property> 
    </bean> 

    <jdbc:embedded-database id="dataSource" type="HSQL"> 
     <jdbc:script location="classpath:db/schema.sql" encoding="UTF-8"/> 
     <jdbc:script location="classpath:db/data.sql" encoding="UTF-8"/> 
    </jdbc:embedded-database> 

</beans> 

我曾嘗試：在persistence.xml中提供了以下屬性：

<property name="hibernate.connection.url" value="jdbc:hsqldb:file:database"/> 
<property name="hibernate.hbm2ddl.auto" value="update" /> 

但它沒有完成它的工作。

實測值的溶液中，改變彈簧上下文：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:context="http://www.springframework.org/schema/context" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
      http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> 

    <bean id="entityManagerFactory" 
     class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" 
     p:persistenceUnitName="DEMO"> 
     <property name="dataSource" ref="dataSource" /> 
     <property name="jpaVendorAdapter"> 
      <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> 
       <property name="showSql" value="true" /> 
       <property name="generateDdl" value="true" /> 
       <property name="database" value="HSQL" /> 
      </bean> 
     </property> 
    </bean> 

    <bean id="dataSource" 
     class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
     <property name="driverClassName" value="org.hsqldb.jdbcDriver" /> 
     <property name="url" value="jdbc:hsqldb:file:build_database" /> 
     <property name="username" value="sa" /> 
     <property name="password" value="" /> 
    </bean> 

</beans>
