Question

我在尝试在eclipse中运行应用程序时遇到此错误（以＆gt; Java应用程序运行）：

Caused by: org.springframework.beans.factory.BeanCreationException: Cannot   determine embedded database driver class for database type NONE. If you want an   embedded database please put a supported one on the classpath.

但是当我在命令窗口（mvn spring-boot：run）中运行时，它运行得很好。

Application.properties：

spring.jpa.database=POSTGRESQL
spring.datasource.platform=postgres
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create-drop
spring.database.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/gafanhotator
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.thymeleaf.cache=false

这很奇怪，我已经尝试过STS，同样的错误。有什么想法吗？

Answer 1

我不知道如何以及为什么但是在源“src / main / resources”中的Java Build Path中，它被设置为排除所有* .java，* .yaml和* .properties文件。我只是将这些模式排除在外，所有这些模式都很棒。

这是一个日食默认吗？
