如何从java代码创建MySQL数据库

java mysql spring hibernate

如何从java代码创建MySQL数据库,java,mysql,spring,hibernate,spring-data,Java,Mysql,Spring,Hibernate,Spring Data,我使用的是springboot/mysql/hibernate。 我试图在java代码中执行简单的sql代码，例如： “创建架构newbase1；” 为了实现这一目标，我改变了一些事情： 我从以下位置更改了数据源： spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase 致： spring.datasource.url=jdbc:mysql://localhost:3306/ 完成后，我只能连接到我的服务器，而不能连接到特定的数据

我使用的是springboot/mysql/hibernate。 我试图在java代码中执行简单的sql代码，例如：

“创建架构newbase1；” 为了实现这一目标，我改变了一些事情：

我从以下位置更改了数据源： spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase

致： spring.datasource.url=jdbc:mysql://localhost:3306/

完成后，我只能连接到我的服务器，而不能连接到特定的数据库。 当我只连接到我的服务器时，我可以轻松地执行该行：

session.createNativeQuery("Create schema newbase1;");
在我的测试项目中，Everythink工作得非常完美。当我在主项目中将数据源从localhost:3306/mydatabase更改为localhost:3306时，问题就开始了。我有很多错误：
