grails中的IllegalArgumentException无法计算表达式'；管理员'；

我在AdminController中的每个请求上都会遇到此错误。其他角色也是如此。我正在使用Grails3.2.9。如果需要更多详细信息，请在下面进行评论。以下是角色类：

@EqualsAndHashCode(includes='authority')
@ToString(includes='authority', includeNames=true, includePackage=false)
class Role implements Serializable {

    private static final long serialVersionUID = 1

    public static final String ROLE_SUPER_ADMIN = "SUPER_ADMIN"
    public static final String ROLE_ADMIN = "ADMIN"
    public static final String ROLE_COMPANY = "COMPANY"
    public static final String ROLE_PILOT = "PILOT"
    public static final String ROLE_MEMBER = "MEMBER"

    String authority

    Role(String authority) {
        this()
        this.authority = authority
    }

    static constraints = {
        authority blank: false, unique: true
    }

    static mapping = {
        cache true
    }
}

这是书堆

最近的一个版本将Spring Security JAR的版本升级到了4.0.x，这改变了角色名称前缀被覆盖的方式。您的角色名称不是以“role_u”开头的，因此它们不会被检测为角色。因此，它们被假定为一个SpEL表达式，并且您将无法将

'ADMIN'

作为表达式进行计算

简单的解决方法是重命名所有角色名称，使其以“role_uu”开头，直到插件再次与Spring Security同步。

我认为角色必须以role开头_
