当我运行独立的 Web 应用程序时，Spring 无法实例化数据源 bean。请注意，我不想在这个项目中使用 JPA 或 hibernate。此时我不知道为什么。我最好的猜测是依赖项或语法问题，但我无法找到问题的解决方案。
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'gameoo' defined in class path resource [com/hf/database/Datasource.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'get' threw exception; nested exception is java.lang.IllegalStateException: No supported DataSource type found
如果有人有一些见解或可以帮助我解决这个问题，那就太好了。
下面是我的“spring.properties”文件
