How can I config the jpa-config.xml to allow the entityManageFactory auto scanning two packages at the same time?

Question

I'm trying to integrate an library to an other one, the following code is the content in jpa-config.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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
    </bean>
    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="packagesToScan" value="com.example1" />
        <property name="persistenceProviderClass" value="org.eclipse.persistence.jpa.PersistenceProvider" />
        <property name="dataSource" ref="dataSource" />
        <property name="jpaVendorAdapter" ref="jpaAdapter" />
        <property name="jpaPropertyMap">
            <map>
                <entry key="eclipselink.weaving" value="false" />
                <entry key="eclipselink.logging.level" value="INFO" />
                <entry key="eclipselink.logging.level.sql" value="INFO" />
                <entry key="eclipselink.cache.shared.default" value="false" />
            </map>
        </property>
    </bean>
</beans>

I'm just wondering if I can do something like this:

<property name="packagesToScan">
    <list>
        <value>com.example1</value>
        <value>com.example2</value>
    </list>
</property>

Answer 1

You can specify multiple packages to scan with below (as included in your question):

<property name="packagesToScan">
   <list>
     <value>com.example1</value>
     <value>com.example2</value>
  </list>
</property>

The packagesToScan attribute is there for xml less configuration ie. no persistence.xml... When using a persistence xml it follows the JPA spec.
