如何使用进度数据库配置数据源/驱动程序管理器？

问题描述

我想在Spring Boot应用程序中配置一个Progress DB 10.2B连接。

我尝试阅读Progress文档，但是没有找到适合我的情况的内容。这是我找到的doc链接：Progress Documentation

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

但是，我不知道如何在Spring Boot中使用Maven在“ pom.xml”中配置其他DriverClass。

我该怎么办？我是否应该使用名称“ DatasourceConfig.java”创建一个新类，并放置一个将返回应由应用程序使用的Progress连接的方法？

我尝试过这种操作（非常新手），但是我不知道如何使其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;

    }

}

我也尝试过“ application.properties”：

spring.datasource.driver-class-name=com.ddtek.jdbc.openedge.OpenEdgeDriver
spring.datasource.url=jdbc:datadirect:openedge://localhost:5522;databaseName=farms

在https://stackoverflow.com/a/36602256/7712038的帮助下创建的pom.xml文件中具有以下依赖性：

<dependency>
        <groupId>com.ddtek.jdbc.openedge</groupId>
        <artifactId>OpenEdgeDriver</artifactId>
        <version>10.2</version>
    </dependency>

它仍然给我以下异常：

解决方法

通常-有效/已知-驱动程序jar文件都被正式打包在一个正式的Maven存储库下，因此，获取所有临时依赖关系会容易得多。在您的情况下（也从您共享的文档中），在初始化Spring Boot应用程序的同时，似乎需要放置多个jar。

一些选项：

如前所述，尝试将所有必需的jar作为自定义/本地软件包安装到本地计算机或私有远程存储库中，然后在pom.xml中创建具有相同名称的依赖项引用。验证最终软件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，仅将它们称为单个jar（不建议将其作为具体解决方案）。一个类似的问题here
手动复制Spring Boot的lib目录（！）中的所有jar（同样，不推荐，仅用于证明）
