我无法连接 MySQL 数据库 WildFly - Hibernate

Question

我想用 JSF 做一个简单的 CRUD，我使用的是 WildFly 9.0.2 服务器。 我已经进行了standalone.xml 和 modules.xml 配置，但我仍然有以下错误：

WARN  [org.jboss.jca.core.connectionmanager.pool.strategy.OnePool] (JCA PoolFiller) IJ000610: Unable to fill pool: javax.resource.ResourceException: IJ031084: Unable to create connection
ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate] (ServerService Thread Pool -- 58) HHH000299: Could not complete schema update: java.sql.SQLException: javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:jboss/datasources/
ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate] (ServerService Thread Pool -- 58) HHH000319: Could not get database metadata: java.sql.SQLException: javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:jboss/datasources/

堆栈太大，此处无法输入。

standalone.xml 的数据源部分：

<datasources>
                <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">

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

                        <max-pool-size>100</max-pool-size>
                        <prefill>true</prefill>
                    </pool>
                    <security>
                        <user-name>root</user-name>
                        <password>admin</password>
                    </security>
                    <statement>

                        <share-prepared-statements>true</share-prepared-statements>
                    </statement>
                </datasource>
                <drivers>
                    <driver name="mysql" module="com.mysql">
                        <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
                    </driver>
                    <driver name="h2" module="com.h2database.h2">
                        <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
                    </driver>
                </drivers>
            </datasources>

还有 Persistence.XML ：

<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="PERSISTENCE_UNIT" transaction-type="RESOURCE_LOCAL">

<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

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

<properties>
<property name="hibernate.hbm2ddl.auto" value="update" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" />
</properties>
</persistence-unit>
</persistence>

有人可以帮助我吗？ 我什么都试过了。

我放弃了使用 WildFly，它非常强大和快速，但很难配置.. 现在我在我的项目中使用 TomCat 9 并且运行良好。

感谢大家的贡献！
