Java Hibernate JPA未在类路径上执行import.sql

我有一个HibernateJPA项目，在类路径上有一个

import.sql

文件。我已经尝试了很多方法让它工作。我的persistence.xml是：

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.1"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="SNAPSHOTPU"
        transaction-type="JTA">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:jboss/datasources/PostgresqlDS</jta-data-source>
        <class>net.example.Actor</class>
        <exclude-unlisted-classes>true</exclude-unlisted-classes>
        <properties>
            <property name="hibernate.show_sql" value="true" />
            <property name="javax.persistence.schema-generation.database.action"
                value="drop-and-create" />
            <property name="hibernate.hbm2ddl.auto" value="create-drop" />
            <property name="hibernate.hbm2ddl.import_files" value="import.sql" />
        </properties>
    </persistence-unit>
</persistence>

尝试（相应地更改javax.persistence.sql-load-script-source路径）：

非常重要的注意import.sql位于src/main/resources中

<properties>
    <property name="hibernate.show_sql" value="true" />
    <property name="javax.persistence.schema-generation.database.action"
        value="drop-and-create" />
    <property name="javax.persistence.sql-load-script-source"
        value="/import.sql" />
</properties>

<properties>
    <property name="hibernate.show_sql" value="true" />
    <property name="javax.persistence.schema-generation.database.action" value="drop-and-create" />
    <property name="javax.persistence.schema-generation.create-source" value="metadata-then-script"/>
    <property name="javax.persistence.sql-load-script-source" value="/import.sql"/>
</properties>
