Spring 如何使用STS创建一个；弹簧靴&x2B；mysql+；冬眠“；网络服务

我是一名android开发者。但是现在，我需要创建一个webservice项目。 我试图通过STS创建一个spring项目。我在网上找到了一些演示代码。但它不起作用。当我运行应用程序时。控制台输出错误日志：

为什么它不自动创建表

请帮助我修复它或告诉我如何创建一个webservice项目，非常感谢。哈哈

我想您可能只需要将以下内容添加到

应用程序。属性

：

spring.jpa.generate-ddl=true

但是，您还将其配置为使用

sqlserverdialent

。这应该是：

org.hibernate.dialect.MySQL5InnoDBDialect

或
