问题
我引入了JPA的一个包 不引入它 启动没问题 引入就报错 但是我还要用到jpa
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
后来发现不是它的问题
看最后一句报错
Correct the classpath of your application so that it contains a single, compatible version of javax.persistence.spi.PersistenceUnitInfo
这个说的是jar冲突，那么解决思路就应该是javax.persistence.spi.PersistenceUnitInfo 直接百度 网上就有很多解决jar冲突的
然后就找到解决思路了：最后解决文章
