grails - 如何永久保存数据？

Question

每次按调试项目时，数据库中的数据都消失了。但是，如果我只按运行项目，它仍然可以。有人可以告诉我我的代码有什么问题吗？我在调试或运行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 Controller

package test

class Test1Controller {
   static scaffold = Test1
}

这是在application.yml里面，我用的是8090端口

我将查看您的application.yml或application.groovy的数据库设置，并检查您的dbcreate设置为什么。这是数据源设置的文档:
