#SpringBoot--Error creating bean with name 'entityManagerFactory' defined in class path resource

有可能引起的原因：

<dependency>
   <groupId>javax.persistencegroupId>
   <artifactId>persistence-apiartifactId>
   <version>1.0.2version>
dependency>

与

<dependency>
   <groupId>org.springframework.bootgroupId>
   <artifactId>spring-boot-starter-data-jpaartifactId>
dependency>

冲突了，将persistence-api这个jar包删除即可
