Question

我想使用带有弹簧靴的轻型管理员。我的项目工作正常，但

时

当我将依赖项添加到pom.xml

时

<lightadmin.version>1.2.0.RC1</lightadmin.version>
dependency>
    <groupId>org.lightadmin</groupId>
    <artifactId>lightadmin</artifactId>
    <version>${lightadmin.version}</version>
</dependency>

会抛出错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [com/boot/configur
ation/HibernateConfiguration.class]: Invocation of init method failed; nested exception is java.lang.AbstractMethodError
        at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1578) ~[spring-b
eans-4.3.2.RELEASE.jar:4.3.2.RELEASE]

如果你可以使用Spring Boot spring-boot-starter-data-jpa

进行自我配置，你为什么要自己配置Hibernate？

http://jsfiddle.net/bnmb05eu/

您还需要pom.xml

中的依赖项

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

带弹簧的轻管理配置

的pom.xml

AppInitializer.java

AppConfig.java

HibernateConfiguration.java
