1.错误原因（异常描述）

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘entityManagerFactory’ defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

测试类错误原因：java.lang.IllegalStateException: Failed to load ApplicationContext

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘entityManagerFactory’ defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

2.异常原因

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory'

Caused by: javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

不应该创建SessionFactory

3.如何解决

1.首先检查你的数据库是否进行配置完成以及正确
下面是我的配置

spring.datasource.url=jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

2.查看是否进行了SpringBoot与MyBatis的整合
如果没有加上配置：如下

@MapperScan("com.ifox.springbootRestful.dao")

3.检查pom中mysql配置驱动是否正确以及版本

不能解决的还是要根据自己的实际情况来解决！！
