Java 如何使用进度数据库配置数据源/驱动程序管理器？

我想在我的Spring Boot应用程序中配置Progress DB 10.2B连接

我试图阅读进度文档，但没有找到任何适合我的场景的内容。这是我找到的文档链接：

我在openedge解决方案中提供了“openedge.jar”驱动程序文件

但是，我不知道如何使用“pom.xml”中的Maven在Spring Boot中配置不同的DriverClass

我该怎么办？我是否应该创建一个名为“DatasourceConfig.java”的新类，并放置一个方法来返回应用程序应该使用的进度连接

我尝试过类似的方法（非常新手），但我不知道如何使它与我的实体和存储库一起工作：

public class DatasourceConfig {

    public DatasourceConfig() throws ClassNotFoundException {
        Class.forName("com.ddtek.jdbc.openedge.OpenEdgeDriver");
    }

    @Bean
    Connection dataSource() throws SQLException {

        String url = "jdbc:datadirect:openedge://localhost:5522;databaseName=farms;user=xul;password=Xul$445";
        Connection con = DriverManager.getConnection(url);
        return con;

    }

}

我还尝试了“application.properties”：

在我的pom.xml文件中具有以下依赖项，这些依赖项是在的帮助下创建的：

通常，-valid/known-driver jar文件被正式打包在一个官方的Maven存储库中，因此获取所有临时依赖项会容易得多。在您的情况下（从您共享的文档中也可以看到），在Spring启动应用程序初始化时，似乎需要安装多个jar

一些选择：

正如您所说的，尝试将所有必需的JAR作为自定义/本地包安装到本地计算机或专用远程存储库中，然后在pom.xml中创建具有相同名称的依赖项引用。验证最终包是否包含所有必需的库（外部/内部取决于您导出最终可执行文件的方式）

使用Maven系统依赖项，只需将它们称为单个JAR（不建议将其作为具体解决方案）。类似的问题

手动复制Spring Boot的lib目录（！）中的所有JAR（同样不推荐，只是为了证明）

---

您的问题似乎是运行时缺少实际的jar？你是如何构建你的应用程序的？马文/格雷德尔？或者您的jar确实存在，但Driver.Class.name错误？快照中是否缺少任何嵌套异常？Hi@AntJavaDev。我现在将发布整个异常。“openedge.jar”文件与我的“pom.xml”文件位于同一文件夹中。位于同一文件夹并不意味着什么，它是否被称为pom.xml中的打包依赖项？不，它不是。我该怎么做？我没有groupId或artifactId来放在tagcool中，让我发布一些选项作为答案
