创建在类路径资源中定义名为'Entity ManagerFactory的bean时出错

Question

我在运行spring应用程序时收到以下错误。我对Spring很陌生，所以很困在这里。需要一些帮助来解决这个问题，或者告诉我如何调试和解决这个问题。我只是通过互联网和做不同的组合在我的Pom文件。

Answer 1

Springspring-boot-starter-data-jpa默认情况下包括hibernate，因此如果您要使用eclipselink，那么从依赖项中排除hibernate是有意义的：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
    <exclusions>
        <exclusion>
            <artifactId>hibernate-entitymanager</artifactId>
            <groupId>org.hibernate</groupId>
        </exclusion>
    </exclusions>
</dependency>
