Grails3 spring安全核心3不能使用域对象

我正在尝试使用spring security core 3.0.4创建一个带有grails 3.1.2的网站。

我使用过这个页面: Grails Spring Security Core

我使用了以下脚本(将“website”替换为我的项目名称):

grails s2-quickstart com.website User Role
grails s2-create-persistent-token com.website.PersistentLogin
grails s2-create-role-hierarchy-entry com.website.RoleHierarchyEntry

然后我将以下内容添加到我的BootStrap.groovy:

if(User.count()==0) {
        Date testDate = new Date()

        Role userRole = new Role('ROLE_USER').save()
        Role adminRole = new Role('ROLE_ADMIN').save()

        User user = new User("John","password").save()
        User admin = new User("Richard","password").save()

        UserRole.create(admin, adminRole)
        UserRole.create(user, userRole)

        UserRole.withSession {
            it.flush()
            it.clear()
        }

        assert User.count() == 2
        assert Role.count() == 2
        assert UserRole.count() == 2

    }

我收到一条关于无法找到User bean类权限的错误,所以我用这个替换了getAuthorities方法(因为将它添加到临时列表不起作用):

Set<Role> getAuthorities() {
    if(this.id){
        return UserRole.findAllBySecUser(this)*.role
    }
    else{
        return [] as Set
    }
}

然后我再次尝试构建,并收到有关UserRole类的异常。

如何解决他的错误?我不知道这个特殊错误意味着什么:/

看起来用户有验证错误但没有保存。您正在使用2-arg构造函数,但如果需要的属性多于用户名和密码,则验证将失败,save()将返回null。

如果您更改代码以创建用户

User user = new User(..., ...)
user.save()
if (user.hasErrors()) {
    println user.errors
}
那么你会看到什么是错的。在构造函数调用后添加缺少的属性:

User user = new User(..., ...)
user.fullName = '...'

或切换到传统的Map构造函数,将其初始化为一行:

User user = new User(username: ..., password: ..., fullName: ...)
