每次我按调试项目时，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。有人可以告诉我代码中有什么问题吗？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'
}
}
这是控制器
package test
class Test1Controller {
static scaffold = Test1
}
这是在application.yml内部，我使用了8090端口

我将查看您的application.yml或application.groovy以获取您的数据库设置，并检查您的dbcreate设置为什么。这是数据源设置的文档： https://docs.grails.org/latest/guide/conf.html#dataSource
