Spring Grails TransientObject异常

这与我的配置有关，你可以在这里找到我的配置。ldap用户被映射到数据库用户表，并且条目被很好地创建。然后userDetails尝试从主用户类获取权限，导致以下异常：

2014-01-31 12:10:52,076 [http-bio-8111-exec-4] ERROR [/step].[default]  - Servlet.service() for servlet [default] in context with path [/step] threw exception

以下是我的用户详细信息类：

import java.util.Collection;

import org.springframework.security.core.GrantedAuthority
import org.springframework.security.ldap.userdetails.LdapUserDetails

import package.Role
import package.User

class MdtUserDetails extends User implements LdapUserDetails{



    public MdtUserDetails(String fullName, String email, String username, String password, boolean enabled, boolean accountExpired,
        boolean accountLocked, boolean passwordExpired, Collection<GrantedAuthority> authorities) {
        super(username: username, password: password, email: email, fullName: fullName, enabled: enabled, accountExpired: accountExpired, accountLocked: accountLocked, passwordExpired: passwordExpired, authorties: authorities)

    }


    @Override 
    public Set<Role> getAuthorities(){
        return super.getAuthorities()
    }

    @Override
    public boolean isAccountNonExpired() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean isAccountNonLocked() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public String getDn() {
        // TODO Auto-generated method stub
        return null;
    }


}

相反，我需要从这里扩展springsecurity用户类：

import org.springframework.security.core.userdetails.User

我相信这是导致我的暂时对象异常的原因，因为答案表明你需要有belongsTo，等等。我的类中确实有这些

Caused by TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: package.User

此消息告诉您，要保存的

用户

对象至少包含一个对另一个未保存域对象的引用

根据您的

用户

类，此未保存的引用可以是

报告

或

发票

对象。 您可以使用以下选项来解决此问题：

在将报告和发票添加到用户之前手动保存它们

或

使用启用报表和发票的自动级联

static mapping = {
  reports cascade: 'all-delete-orphan'
  reports invoices: 'all-delete-orphan'
}

或

将

项下的
关系添加到
发票和
报告中
：

static belongsTo = [user: User]

谢谢你的建议。我已经有了属于我的关系。我尝试将“全部删除孤立项”级联到用户的类中，但没有成功。
User
中的
password
映射到哪个列？它只是映射到password。用户表映射到步骤\用户。
static mapping = {
  reports cascade: 'all-delete-orphan'
  reports invoices: 'all-delete-orphan'
}

static belongsTo = [user: User]
