Spring security 注解预计将是内联常量

Question

当我尝试在 @Secured 注释之外定义字符串时，我在 grails 中遇到以下错误。

我收到以下错误 Role.USER' to be an inline const of type java.lang.String not a property expression in @grails.plugin.springsecurity.annotation.Secured

class Role {
    final static String USER = "ROLE_USER"
    final static String ADMIN = "ROLE_ADMIN"


    public final static String[] LOGINED_USER = [USER, ADMIN].asImmutable()

}

下面的控制器说明了我的问题..

class MyController {

    @Secured(["permitAll"]) //Works fine
    def action1() {
    }


    @Secured(LOGINED_USER) //Doesn't work
    def action2() {
    }

    @Secured([Role.ADMIN, Role.USER]) //Doesn't work
    def action3() {
    }


    @Secured(["ROLE_ADMIN", "ROLE_USER"]) //Works fine
    def action4() {
    }
}

Answer 1

您必须显式公开 USER 和 ADMIN 常量，添加public修饰符

public final static String USER = "ROLE_USER"
public final static String ADMIN = "ROLE_ADMIN"

在这种情况下，Groovy 将不会使用geters setter注释中不允许的内容。
