有一些等类也有，但我不是张贴由于大段，如果任何人需要具体的，我会张贴。

当我尝试运行时,控制台出现以下错误：

请朋友们帮帮我。

Answer 1

正如Michal指出的，这是一个DB问题--

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 at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues(AutowiredAnnotationBeanPostProcessor.java:334)

您的MySQL DB可能没有运行，或者您可能没有在spring属性中提供数据源连接[我看到您有一个MySQL依赖项引用]

对于调试或测试用例，您可以尝试H2-

<!-- https://mvnrepository.com/artifact/com.h2database/h2 -->

    <groupId>com.h2database</groupId>
