从persistance.xml到jboss数据源配置外部化postgresql模式

Question

这是我的persistance.xml

<?xml version="1.0" encoding="UTF-8"?>

http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd“＆GT;

<persistence-unit name="cframe-context-unit">

    <jta-data-source>java:jboss/datasources/ClicencePostgresDS</jta-data-source>

    <jar-file>myModel.jar</jar-file>

    <properties>
        <property name="hibernate.archive.autodetection" value="class"/>
        <property name="hibernate.format_sql" value="true"/>
        <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
        <property name="hibernate.default_schema" value="dev"/>
        <property name="hibernate.hbm2ddl.auto" value="update"/> 
    </properties>

</persistence-unit>

我想删除此行<property name="hibernate.default_schema" value="dev"/>并在jboss数据源配置中设置它。 这是我目前的jboss数据源配置

<datasource jta="false" jndi-name="java:jboss/datasources/ClicencePostgresDS" pool-name="ClicencePostgresDS" enabled="true" use-java-context="true" use-ccm="false">
