我有一个问题。我正在集成 EJB、JAX-RS、CDI、JPA 和数据源。当我将这些集成到 wildfly-swarm 中时，会出现一些无法正常工作的问题。

 yaml.xml:

        datasources:

          jdbc-drivers:
                    com.mysql:
                    driver-class-name: com.mysql.jdbc.Driver
                    xa-datasource-class-name: com.mysql.jdbc.jdbc2.optional.MysqlXADataSource
                    driver-module-name: com.mysql

          data-sources:
                    PicketlinkDS:
                    driver-name: com.mysql
                    connection-url: jdbc:mysql://localhost:3306/testjpa
                    user-name: root
                    password: javacom2
                    jta : true
                    use-java-context: true 
                    min-pool-size : 8
                    max-pool-size : 20
                    pool-prefill  : true
                    connection-checker-class-name : org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker
                    background-validation : true
                    exception-sorter-class-name : org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter
                    connection-properties : CharacterEncoding/ UTF-8 UseUnicode/true

主类：

ClassLoader cl = Main.class.getClassLoader();
URL stageConfig = cl.getResource("project-development.yml");
Swarm swarm = new Swarm().withConfig(stageConfig);

// Create one or more deployments
JAXRSArchive deployment = ShrinkWrap.create(JAXRSArchive.class);
deployment.addAsWebInfResource(new ClassLoaderAsset("META-INF/persistence.xml", Main.class.getClassLoader()), "classes/META-INF/persistence.xml");
// Add resource to deployment
//deployment.addClass(PmsPersonService.class);
deployment.addClass(Person.class);
// deployment.addClass(EntityManagerProvider.class);
deployment.addAsWebInfResource(new ClassLoaderAsset("META-INF/load.sql", Main.class.getClassLoader()), "classes/META-INF/load.sql");
deployment.addResource(RestApplication.class);
deployment.addResource(HelloWorldEndpoint.class);
deployment.addAllDependencies();
swarm.start();
swarm.deploy(deployment);

异常：“WFLYCTL0412：未安装的必需服务：”=>“jboss.naming.context.java.jboss.datasources.PicketlinkDS”]，

想法，运行上如何处理这个异常？好着急！！！！！！

首先，我建议删除自定义 main() ，因为您在那里所做的任何事情都无法通过 Mavenwar打包来实现。

其次，我认为您的 yaml 缺少swarm:第一级，您也可以删除 JDBC Driver 创建并让 WF Swarm 为您完成。为此，我切换driver-name到mysql，只要 MySQL 的 JDBC 驱动程序依赖项是项目的一部分，它就可以工作。

swarm:
  datasources:
    data-sources:
      PicketlinkDS:
        driver-name: mysql
        connection-url: jdbc:mysql://localhost:3306/testjpa
        user-name: root
        password: javacom2
        jta: true
        use-java-context: true 
        min-pool-size: 8
        max-pool-size: 20
        pool-prefill: true
        connection-checker-class-name: org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker
        background-validation: true
        exception-sorter-class-name: org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter
        connection-properties: CharacterEncoding/ UTF-8 UseUnicode/true
