如何在grails中永久保存数据？

Question

每次我按调试项目，我数据库中的数据都消失了。但如果我只按运行项目，它仍然很好。有人可以告诉我我的代码有什么问题吗？即时调试或运行ning 项目时没有出现错误。

package test

class Test1 {
    String name
    int age
    String email
    String gender

    static constraints = {
        email email: true,blank: false
        gender inList:["Male","Female"]
    }

    static mapping = {
        table 'test1'
        version false
        id generator: 'increment'
        name column: 'name'
        age column: 'age'
        email column: 'email'
        gender column: 'gender'
    }
}

这是控制器

package test

class Test1Controller {
   static scaffold = Test1
}

这是在application.yml里面，我用的是8090端口

我会查看您的 application.yml 或 application.groovy 数据库设置，并检查您的 dbcreate 设置。这是数据源设置的文档： https://docs.grails.org/latest/guide/conf.html#dataSource
