Spring启动错误org.hibernate.exception.GenericJDBCException:无法打开JDBC连接以执行DDL [英] Spring boot error org.hibernate.exception.GenericJDBCException: Unable to open JDBC Connection for DDL execution

问题描述

用数据spring jpa和mysql连接器运行jar包spring boot应用在windows 10环境和linuxmint环境下结果不同.

Run the Jar package the spring boot application with data spring jpa and the mysql connector have different results in the Windows 10 environment and the linuxmint environment.

如果此应用程序在 linuxmint 上运行，它可以完美运行，但如果它在 Windows 10 中启动，则会出现如下错误:

If this application runs on linuxmint it works perfectly, but if it starts in Windows 10 an error like this occurs:

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

this is pom.xml dependencies

还有这个application.properties

And this 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:这两个环境都使用相同的 mariadb 版本，即 10.1.19.编码在linuxmint环境中完成

Note: Both of these environments use the same mariadb version, which is 10.1.19. Coding is done in the linuxmint environment

推荐答案

尝试改变

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

到

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