Automated tests JPA 2.1使用Arquillian&；从persistence.xml中删除脚本执行；收缩膜

我正在编写一些Arquillian（使用Shrinkwrap）测试，我目前通过persistence.xml使用JPA 2.1创建和删除脚本自动化：

// src/test/resources-wildfly-remote/test-persistence.xml
// runs fine, configured as resource in pom.xml
<?xml version="1.0" encoding="UTF-8"?>
    <persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="testPU" transaction-type="JTA">
        <!-- Wildfly JPA specific implementation config -->
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
        <jta-data-source>java:/jdbc/Test</jta-data-source>
        <exclude-unlisted-classes>false</exclude-unlisted-classes>
        <properties>
            <property name="hibernate.archive.autodetection" value="class" />
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
            <property name="javax.persistence.schema-generation.database.action"
            value="drop-and-create" />
            <property name="javax.persistence.schema-generation.create-source"
            value="script" />
            <property name="javax.persistence.schema-generation.drop-source"
            value="script" />
            <property name="javax.persistence.schema-generation.create-script-source"
            value="META-INF/create-test.sql" />
            <property name="javax.persistence.schema-generation.drop-script-source"
            value="META-INF/drop-test.sql" />
        </properties>
    </persistence-unit>
</persistence>

测试和创建脚本运行良好，但不会发生删除，是否有人有相同的问题

编辑（添加日志）：

我会继续努力，任何进展都会在这里报告

编辑在@After测试方法下手动执行脚本：

protected static void dropAllTables(UserTransaction utx, EntityManager em)
        throws SystemException {
    // Temporary solution for table dropping after tests
    try {
        InputStream fis = Thread.currentThread().getContextClassLoader()
                .getResourceAsStream("META-INF/drop-teste.sql");

        StringBuilder builder = new StringBuilder();
        int ch;
        while ((ch = fis.read()) != -1) {
            builder.append((char) ch);
        }

        String[] dropCommands = builder.toString().split(";");

        utx.begin();
        for (String command : dropCommands) {
            em.createNativeQuery(command).executeUpdate();
        }
        utx.commit();
    } catch (Exception e) {
        utx.rollback();
    }
}

看起来Hibernate正在尝试执行您的drop命令，但没有成功

这可能是由于表之间的约束造成的。因此，请仔细检查删除顺序是否正确：

• 首先：删除没有ForeignKey引用的表
• 第二：删除下一个这样的表
• 依此类推-直到最基本的表，其中没有任何FKs内

Hi Grzesiek，奇怪的是，我使用完全相同的脚本来删除表，我甚至手动执行drop命令，读取文件，作为一个临时解决方案，我将用代码段编辑问题。至于约束错误，由于我手动执行，已经碰到了，并且已经修复了。无论如何，thnx用于双重检查：）哦，对于drop脚本，它的编写尽可能简单，比如：

drop TABLE TABLE 1；下表2
--project
    --src/test
        --java
            --com/example/MyTest.java
        --resources
            --create-test.sql
            --drop-test.sql
            --example-ds.xml
        --resources-wildfly-remote
            --test-persistence.xml
