Spring Batch 使用带有 Spring Boot 的 MongoDB 抛出无法确定数据库类型的嵌入式数据库驱动程序类 NONE

Posted 2023-02-26

【中文标题】Spring Batch 使用带有 Spring Boot 的 MongoDB 抛出无法确定数据库类型的嵌入式数据库驱动程序类 NONE

【英文标题】：Spring Batch using MongoDB with Spring Boot throws Cannot determine embedded database driver class for database type NONE

【发布时间】：2017-07-30 01:38:56

【问题描述】：

我在使用 mongodb 的 Spring Batch 应用程序的服务器启动时遇到以下异常。请注意，我对 Mongo DB 进行了正确配置，但应用程序仍在尝试加载 JDBC 数据源。

行动：

如果您想要一个嵌入式数据库，请在 类路径。如果您有要从 您可能需要激活它的特定配置文件（没有配置文件是 目前处于活动状态）。

【问题讨论】：

请注意我正在使用 JBoss EAP 7 进行部署，并且我在 pom.xml 中排除了 spring-boot-starter-tomcat

【参考方案1】：

我觉得 spring jdbc 对批处理的依赖希望您提供数据源详细信息。如果您忽略 DataSourceAutoConfiguration 这应该运行。

将此添加到您的 Spring Boot 应用程序类中

@EnableAutoConfiguration(exclude=DataSourceAutoConfiguration.class)
