我是 grails 的新手，我创建了一个用户域类和用户配置文件域类。而这些类(class)是有亲戚关系的。 域类如下所示
class User {
transient springSecurityService
String username
String password
String email
static hasOne = [profile: UserProfile]
boolean enabled = true
boolean accountExpired
boolean accountLocked
boolean passwordExpired
static transients = ['springSecurityService']
static constraints = {
username blank: false, unique: true
password blank: false
email blank: false, nullable: false, unique: true, email: true
profile nullable:true, unique: true
}
class UserProfile {
String firstname;
String team;
String pidgin;
String phone;
User user
static constraints = {
firstname nullable:true
team nullable:false, blank:false
pidgin nullable:false, blank:false
phone nullable:false
}
}
在我的服务类
class UserService{
public User createUserProfile(UserProfile profile,String email) {
User user = User.findByEmail(email)
if(!user)
//no user found
profile.user = user
profile.save()
user.profile = profile
user.save(failOnError: true)
}
}
当运行我的项目时，它完全按照任何方式运行并执行 createUserProfile
但是，当使用相同的函数更新我的用户配置文件 user.save(failOnError: true)
抛出 JdbcSQLException。
详细错误如下。

如何消除这个异常..或错误
提前致谢
最佳答案
尝试保存域并引用未保存并尝试引用的对象时发生约束错误。所以做一些欺骗性的例子，比如:你也应该制作唯一的用户
new Face(nose:new Nose()).save()
上面的例子将保存面部和 Nose 。请注意，反之则不然，会因 transient 面而导致错误:

消息:唯一索引或主键违规:“CONSTRAINT_INDEX_C ON PUBLIC.USER_PROFILE(USER_ID)”； SQL语句:
