Grails 2 - 无法创建spring安全域对象

Question

我在运行grails s2-quickstart com.testApplication.secureApplication User Role后自动生成我所做的域对象时grails run-app,从grails插件页面安装了spring security app,并得到了以下异常:

事情是我的数据库配置正确,因为我得到了表role和user_role.但是用户没有在我的生成中生成postgresql db.我的自动生成的实现user domain object看起来像这样:

class User {

    transient springSecurityService

    String username
    String password
    boolean enabled = true
    boolean accountExpired
    boolean accountLocked
    boolean passwordExpired

    static transients = ['springSecurityService']

    static constraints = {
        username blank: false, unique: true
        password blank: false
    }

    static mapping = {
        password column: '`password`'
    }

    Set<Role> getAuthorities() {
        UserRole.findAllByUser(this).collect { it.role } as Set
    }

    def beforeInsert() {
        encodePassword()
    }

    def beforeUpdate() {
        if (isDirty('password')) {
            encodePassword()
        }
    }

    protected void encodePassword() {
        password = springSecurityService.encodePassword(password)
    }
}

我感谢你的回答!

Answer 1

'user'是Postgres中的保留名称.您可以通过在域类中设置映射并使用备用名称来避免这种情况.

 static mapping = { table 'myusers' }

这样您的域类保持不变.您也可以使用类似于"密码"的方式来逃避名称.
