如何使用进度数据库配置数据源/驱动程序管理器？

【问题标题】：How to configure Datasource/Driver Manager with Progress Database?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】：

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

我尝试阅读 Progress 文档，但没有找到适合我的情况的任何内容。这是我找到的文档链接：Progress Documentation

我有 OpenEdge 解决方案中提供的“openedge.jar”驱动文件。

但是，我不知道如何在“pom.xml”中使用 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”的新类并放置一个返回应用程序应该使用的 Progress 连接的方法？

我尝试过这样的事情（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;

    }

}

我也试过了“application.properties”：

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

在我的 pom.xml 文件中使用以下依赖项，在 https://stackoverflow.com/a/36602256/7712038 的帮助下创建：

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

它仍然给我以下异常：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'inMemoryDatabaseShutdownExecutor' defined in class path resource [org/springframework/boot/devtools/autoconfigure/DevToolsDataSourceAutoConfiguration.class]: Unsatisfied dependency expressed through method 'inMemoryDatabaseShutdownExecutor' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.IllegalStateException: Cannot load driver class: com.ddtek.jdbc.openedge.OpenEdgeDriver

【问题讨论】：

  • 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？行家/毕业？或者你的 jar 确实在那里，但 Driver.Class.name 是错误的？您的快照中是否缺少任何嵌套异常？
  • 嗨@AntJavaDev。我现在将发布整个异常。 “openedge.jar”文件与我的“pom.xml”文件在同一个文件夹中。
  • 在同一个文件夹中并不意味着什么，它是否被称为 pom.xml 中的打包依赖项？
  • 不，不是。我怎样才能做到这一点？我没有 groupId 或 artifactId 放入 标签
  • 酷，让我发布一些选项作为答案

标签： java spring spring-boot openedge progress-db


【解决方案1】：

通常 - 有效/已知 - 驱动程序 jar 文件正式打包在官方 Maven 存储库下，因此获取所有临时依赖项会容易得多。在您的情况下（也来自您共享的文档），在 Spring Boot 应用程序被初始化时，似乎需要放置多个 jar。

一些选项：

  1. 如您所说，尝试将所有必需的 jars 作为自定义/本地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）。

  2. 使用 Maven 系统依赖项，并将它们称为单个 jars（不推荐作为具体解决方案）。类似问题here

  3. 手动复制 Spring Boot 的 lib 目录中的所有 jars (!)（再次不推荐，只是为了证明）

    【解决方案2】：

    Você precisar simular a jar "openedge.jar" para adicionar no repository do ".m2", da seguinte form:

    mvn install:install-file
   -Dfile=src\main\resources\driver\openedge.jar
   -DgroupId=ddtek
   -DartifactId=com.ddtek
   -Dversion=1.0
   -Dpackaging=com.ddtek
   -DgeneratePom=true

    Após fazer isso vai gerar umadependência no repository m2，então adiciona da seguinte forma，em seu arquivo "pom.xml" então reconhecerá o driver

    <!-- JDBC dependencia, rodar escript para simular repository na pasta m2 -->
<dependency>
     <groupId>com.ddtek</groupId>
     <artifactId>ddtek</artifactId>
     <version>1.0</version>
</dependency>
