Question

使用spring security的s2-quickstart脚本生成User，Role和UserRole类后，我现在想要向用户类添加字段，例如电子邮件。

我的用户类包含：

//User.groovy
String username
String password
String email
boolean enabled = true
boolean accountExpired
boolean accountLocked
boolean passwordExpired

一切似乎都有效，直到我按照文档中的教程执行以下操作

//BootStrap.goovy
def adminRole = new Role(authority:'ROLE_ADMIN').save(flush: true)
def adminUser = new User(username:'admin', password:'password')
adminUser.save(flush: true)
UserRole.create adminUser, adminRole, true

这产生了输出：

根据dmahapatro的要求，这是我的UserRole类，不是从生成的模型中编辑的

package uk.co.xonos.bookings

import org.apache.commons.lang.builder.HashCodeBuilder

class UserRole implements Serializable {

    private static final long serialVersionUID = 1

    User user
    Role role

    boolean equals(other) {
        if (!(other instanceof UserRole)) {
            return false
        }

        other.user?.id == user?.id &&
        other.role?.id == role?.id
    }

    int hashCode() {
        def builder = new HashCodeBuilder()
        if (user) builder.append(user.id)
        if (role) builder.append(role.id)
        builder.toHashCode()
    }

    static UserRole get(long userId, long roleId) {
        UserRole.where {
            user == User.load(userId) &&
            role == Role.load(roleId)
        }.get()

    static boolean exists(long userId, long roleId) {
        UserRole.where {

            role == Role.load(roleId)

        int rowCount = UserRole.where {

根据塞尔吉奥·米歇尔斯的要求，完成了他的sugestions后，打印出以下内容：

grails.validation.ValidationErrors: 1 errors
Field error in object 'uk.co.xonos.bookings.User' on field 'email': rejected value [null]; codes [uk.co.xonos.bookings.User.email.nullable.error.uk.co.xonos.bookings.User.email,uk.co.xonos.bookings.User.email.nullable.error.email,uk.co.xonos.bookings.User.email.nullable.error.java.lang.String,uk.co.xonos.bookings.User.email.nullable.error,user.email.nullable.error.uk.co.xonos.bookings.User.email,user.email.nullable.error.email,user.email.nullable.error.java.lang.String,user.email.nullable.error,uk.co.xonos.bookings.User.email.nullable.uk.co.xonos.bookings.User.email,uk.co.xonos.bookings.User.email.nullable.email,uk.co.xonos.bookings.User.email.nullable.java.lang.String,uk.co.xonos.bookings.User.email.nullable,user.email.nullable.uk.co.xonos.bookings.User.email,user.email.nullable.email,user.email.nullable.java.lang.String,user.email.nullable,nullable.uk.co.xonos.bookings.User.email,nullable.email,nullable.java.lang.String,nullable]; arguments [email,class uk.co.xonos.bookings.User]; default message [Property [{0}] of class [{1}] cannot be null]

Answer 1

这可能是因为您的用户创建失败了，而您没有验证它。尝试将BootStrap更改为：

def adminRole = new Role(authority:'ROLE_ADMIN')
assert adminRole.save(flush: true)
def adminUser = new User(username:'admin', password:'password')
assert adminUser.save(flush: true)

如果失败，请更改以打印错误：

adminUser.validate()
println adminUser.errors

我的猜测是你没有在验证栏中添加电子邮件，这是强制性的。

Answer 2

这可能是因为您的域类User或Role包含au属性id。此id属性用于UserRole。这是不允许的，因为Grails Spring插件使用了参数名id。在Grails spring插件中，此参数的类型很长。

解决方案： 将您的媒体资源名称从id更改为uuid。或删除该属性。

例如： def role1 = Role.findOrSaveWhere(authority: 'ROLE_ADMIN') def defaultUser = User.findOrSaveWhere(username: 'admin', password: 'password', ) if(!defaultUser.authorities.contains(role1)){ UserRole.create(defaultUser,role1,true) } 希望有所帮助。
