Question

在Windows 10环境和linuxmint环境中，使用数据spring jpa和mysql连接器运行spring boot应用程序的Jar包会有不同的结果。

如果此应用程序在linuxmint上运行，则可以正常运行，但如果在Windows 10中启动，则会发生如下错误：

ERROR org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: 
Invocation of init method failed; nested exception is javax.persistence.PersistenceException: 
[PersistenceUnit: default] Unable to build Hibernate SessionFactory; 
nested exception is org.hibernate.exception.GenericJDBCException: 
Unable to open JDBC Connection for DDL execution

这是pom.xml依赖项

还有这个application.properties

# datasourcce
spring.datasource.url=jdbc:mysql://localhost/apotekfxboot
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

# hibernate
spring.jpa.hibernate.ddl-auto=update
spring.jpa.generate-ddl=true
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true

注意：这两种环境都使用相同的mariadb版本10.1.19。编码是在linuxmint环境中完成的

Answer 1

尝试更改

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

到

spring.datasource.driverClassName=com.mysql.jdbc.Driver

Spring Boot错误org.hibernate.exception.GenericJDBCException：无法打开JDBC连接以执行DDL
