Question

何时使用Spring Roo和mysql并使用

security setup --provider SPRINGLETS_JPA

当我现在启动应用程序时，我收到错误Stacktrace

问题是什么我必须添加什么来解决这个问题？

Answer 1

当您包含SPRINGLETS_JPA安全类型时，项目中会包含新的Spring Boot自动配置。此外，在您的上下文中注册了一个名为UserLogin的新实体。

在看到您的错误日志org.hibernate.dialect.MySQL5Dialect does not support pooled sequences后，我检查了UserLogin实体，并且我发现@Id字段包含以下注释，该注释用于配置id值的工作方式生成。

@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "userLoginGen")

正如您所看到的，它使用的是GenerationType SEQUENCE，但MySQL数据库不支持此类型。

我只是在Springlets项目中创建了以下问题来解决这个问题。

希望它有所帮助，

Answer 2

您是否在spring.jpa.hibernate.ddl-auto中使用application.properties属性？

要解决此问题，我遇到了同样的问题，我保留了该属性的首次构建/运行，并且在数据库中创建表时，我删除了ddl-auto属性，该错误消失了。 ..

我还没有实现用户注册功能，我不确定，如果我尝试插入一个新用户，该错误会再次发生！

让我知道怎么回事？
