Question

当数据源标有jta=true时，我有一个无法在Wildfly10中创建数据库架构的JPA单元。任何想法我怎么能解决这个问题？

堆栈跟踪：

javax.persistence.PersistenceException: Could not set provided connection [org.jboss.jca.adapters.jdbc.jdk7.WrappedConnectionJDK7@12f9ae77] to auto-commit mode (needed for schema generation)

Wildfly数据来源：

<datasource jta="true" jndi-name="java:/xxx" pool-name="xxx" enabled="true" use-ccm="true">
  <connection-url>jdbc:mariadb:failover://xxx/xxx</connection-url>
  <driver-class>org.mariadb.jdbc.Driver</driver-class>
  <driver>mariadb-java-client-1.5.8.jar</driver>
  ..
</datasource>

持久性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="xxx" transaction-type="JTA">
    <jta-data-source>java:/xxx</jta-data-source>
    <class>xxx</class>
    <properties>
      <property name="javax.persistence.schema-generation.database.action" value="create" />
      <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.JBossAppServerJtaPlatform" />
    </properties>
  </persistence-unit>
</persistence>

标记为启用JTA的Wildfly数据源无法自动创建架构
