我必须为PostgreSQL版本10.1实现Grails 3.3.0 Web界面作为数据库和spring-security-core版本3.2.0。
我在Linux笔记本电脑上安装了PostgreSQL，并使用Postgres用户创建了webInterfaceDev数据库。
但是，每次我想启动项目时都会收到错误＆＃34;对象引用未保存的瞬态实例＆＃34;。
这是我得到的错误：
2017-11-23 11:26:55.634 ERROR --- [ main] o.s.boot.SpringApplication : Application startup failed

简短的故事
您的User.findOrSaveWhere(username:"admin", password:"password")是问题所在。如果您在没有password:"password"的情况下尝试，则会在启动user.password='password'时考虑设置密码new User。
数据库中保存的密码经过哈希处理，与您指定的密码不匹配。因此，每次运行应用时，都找不到匹配的用户，并尝试保存新用户，但username违反了unique约束。
Deatils -
我尝试使用以下代码 -
def xadminRole = Role.findOrSaveWhere(authority:"XYZROLE_XADMIN")
def xuser = User.findOrSaveWhere(username:"xxzadmin", password:"password")
if(!xuser.authorities.contains(xadminRole)){
UserRole.create(xuser,xadminRole,true)
}
第一次工作正常并插入User
我第二次运行应用程序时，我的用户实例出现以下错误
Field error in object 'com.xxx.ovr.User' on field 'username': rejected value [xxzadmin]; codes [[username,class com.xxx.ovr.User,xxzadmin]; default message [Property [{0}] of class [{1}] with value [{2}] must be unique]
最后
org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.xxx.ovr.User
用户密码 -
$2a$10$b1Ybjt9.XVgkDi.HRgGgpeyL7WsSFMFl0jpSWy60JfTfTDNRQH/Fu
$2a$10$8HTYeE8uJgmMzclc0lku5euUpNfqa3RUZeBBs7XaJ9Z5CpT/0Prtq
所以你找不到一个带有普通密码的user - '密码'，它在散列后保存在数据库中（上面给出的例子）。要使用用户名和密码匹配用户，您可以查看帖子 -
spring security encode password with bcrypt algorithm
Grails Spring-Security -how to compare passwords-
<强>更新
借助@ BurtBeckwith的有用评论，我更正了“哈希”取代“加密”的答案
对于密码哈希算法，请查看1.2和3.3.2部分 https://grails-plugins.github.io/grails-spring-security-core/latest/
相关文章

对于Hash和Encryption之间的差异，请检查

答案 1 :(得分：0)
在Bootstrap.groovy中，尝试下面的简单内容
def init = { servletContext ->
if(User.count() == 0){
def adminRole = new Role(authority: 'ROLE_ADMIN').save(flush:true)
def admin = new User(username: 'admin', password: 'testpassed').save(flush:true)
UserRole.create admin, adminRole
// as we call to create, flush the session explicitly ..
UserRole.withSession {
it.flush()
it.clear()
}
// instead you can put >
// new UserRole(admin, adminRole).save(flush:true)
// Do more stuff with admin user
}
}
只需要一件小事，将db url放入application.yml
url: jdbc:postgresql://localhost:5432/yourDBName
