Question

我试图在Wildfly Swarm应用程序中将SQLite数据库与Hibernate一起使用。我正在使用Swarm版本2018.5.0，据我了解，该版本基于Wildfly 11.0.0.Final。因此，我首先在Wildfly上完成了所有工作，然后尝试在Swarm上进行复制，但没有成功。

这是我在Wildfly上工作的目的

在Wilfly内部创建文件modules\system\layers\base\org\sqlite\main\module.xml，其内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.5" name="org.sqlite">
    <resources>
        <resource-root path="sqlite-jdbc-3.23.1.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
    </dependencies>
</module>

也将文件sqlite-jdbc-3.23.1.jar放在同一目录中。

编辑了standalone.xml的本节：

    <subsystem xmlns="urn:jboss:domain:datasources:5.0">
        <datasources>
            [...]
            <datasource jndi-name="java:/MyAppOfflineDS" pool-name="MyAppOfflineDS" enabled="true">
                <connection-url>jdbc:sqlite:file:MyApp.db</connection-url>
                <driver>sqlite</driver>
                <security>
                    <user-name>sa</user-name>
                    <password>sa</password>
                </security>
            </datasource>
            <drivers>
                [...]
                <driver name="sqlite" module="org.sqlite">
                    <driver-class>org.sqlite.JDBC</driver-class>
                </driver>
            </drivers>
        </datasources>
    </subsystem>

在我的Maven项目中使用以下内容创建文件src\main\resources\META-INF\persistence.xml：

<persistence [...]
             version="2.1">
    <persistence-unit name="MyApp" transaction-type="JTA">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
        <jta-data-source>java:/MyAppOfflineDS</jta-data-source>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.SQLiteDialect" />
            <property name="hibernate.hbm2ddl.auto" value="create" />
        </properties>
    </persistence-unit>
</persistence>

并将此依赖项添加到我的pom.xml：

    <dependency>
        <groupId>com.zsoltfabok</groupId>
        <artifactId>sqlite-dialect</artifactId>
        <version>1.0</version>
    </dependency>

一切正常，休眠功能全部正常。

这是我尝试在Swarm上运行的方法

按照此处的说明进行操作： https://howto.wildfly-swarm.io/create-a-datasource/

使用以下内容创建文件src\main\resources\project-defaults.yml：

swarm:
  datasources:
    data-sources:
      MyAppOfflineDS:
        jndi-name: java:/MyAppOfflineDS
        connection-url: jdbc:sqlite:file:MyApp.db
        driver-name: sqlite
        user-name: sa
        password: sa
    jdbc-drivers:
      sqlite:
        driver-module-name: org.sqlite
        driver-class-name: org.sqlite.JDBC

将此依赖项添加到我的pom.xml：

    <dependency>
        <groupId>org.xerial</groupId>
        <artifactId>sqlite-jdbc</artifactId>
        <version>3.23.1</version>
    </dependency>

但是当我尝试运行时，出现以下错误：

2018-06-30 10:57:21,154 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 21) WFLYCTL0013: Operation ("add") failed - address: ([
    ("subsystem" => "datasources"),
    ("jdbc-driver" => "sqlite")

        "jboss.driver-demander.java:/MyAppOfflineDS is missing [jboss.jdbc-driver.sqlite]"
    ]
}

在Wildfly Swarm上安装SQLite驱动程序
