使用MongoDB和Spring Boot抛出的Spring批处理无法确定数据库类型NONE的嵌入式数据库驱动程序类

Question

我在使用MongoDB的Spring批处理应用程序的服务器启动过程中遇到以下异常。请注意，我对Mongo DB有正确的配置，但应用程序仍在尝试加载JDBC数据源。

如果您想要一个嵌入式数据库，请在类路径上放置一个受支持的数据库。如果要从特定配置文件加载数据库设置，则可能需要激活它（当前没有活动的配置文件）。

Answer 1

我觉得spring jdbc与batch的依赖关系希望您提供数据源的详细信息。如果忽略DataSourceAutoConfiguration，则它应该运行。

在spring boot applicaiton类中添加这个

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
