我想通过声明数据源在 Jboss Wildfly Swarm 中使用postgresql . 应用程序启动错误消息是：

无法为驱动程序org.postgresq加载模块

主类内容：

public static void main(String[] args) throws Exception {
            Container container = new Container();



    container.fraction(new DatasourcesFraction()
                    .jdbcDriver("postgresql", (d) -> {

      d.driverDatasourceClassName("org.postgresql.Driver");

      d.xaDatasourceClass("org.postgresql.xa.PGXADataSource");
      d.driverModuleName("org.postgresql");
                    })
    .dataSource("ExampleDS", (ds) -> {
      ds.driverName("postgresql");

      ds.connectionUrl("jdbc:postgresql://localhost:5432/test_db");
      ds.userName("sa");
      ds.password("sa");
                    })
    );
            container.start();

            JAXRSDeployment appDeployment = new JAXRSDeployment( container );
            appDeployment.addResource(MyResource.class);

            container.deploy(appDeployment);
        }

谢谢你的帮助

    以下wildfly-swarm示例可能很有用 . 它描述了如何在Wildfly Swarm容器中部署驱动程序和数据源:(有IT测试覆盖它）

    https://github.com/wildfly-swarm/wildfly-swarm-examples/tree/master/datasource/datasource-deployment

    编辑：数据源部署示例文档不是最新的，有效示例here

    以下是运行此示例main方法时的日志 . 数据源部署似乎工作正常：

    您是否还在类路径中添加了驱动程序库，如果您正在使用maven，则通过在运行时依赖项中声明它？
