Question

我试图建立一个春季启动项目，我检查了web，jdbc，jpa和thymeleaf，但得到了这个错误：

this.props.history.push('/search');

这是pom.xml

Answer 1

从依赖项中删除：

hibernate-core
hibernate-entitymanager

另外，spring-boot-starter-jdbc

spring-boot-starter-data-jpa已经包含具有正确版本的此依赖项

看看spring-boot-starter-data-jpa dependencies

创建名称为'jpaMappingContext'的bean时出错
