security - GORM 的这个实现目前不支持基于字符串的查询，如 [executeQuery]

Question

我正在尝试使用 grails mongo 插件在 mongodb 中持久化 spring-security-acl 域对象。在执行以下代码行时

aclUtilService.addPermission Phone.class, phoneInstance.id, new PrincipalSid(username), BasePermission.ADMINISTRATION

我收到以下错误:

String-based queries like [executeQuery] are currently not supported in this  implementation of GORM. Use criteria instead.. Stacktrace follows:
Message: String-based queries like [executeQuery] are currently not supported in this implementation of GORM. Use criteria instead.

有什么困难吗？

Grails 配置详情:

app.grails.version=2.0.3
app.name=eateri
app.servlet.version=2.5
app.version=0.1
plugins.mongodb=1.0.0.RC5
plugins.spring-security-acl=1.1
plugins.spring-security-core=1.2.7.2

正如@sudhir 提到的，aclService 中有一些方法使用 hql executeQuery 方法，例如:

    protected AclObjectIdentity retrieveObjectIdentity(ObjectIdentity oid) {
        return AclObjectIdentity.executeQuery(
                "FROM AclObjectIdentity " +
                "WHERE aclClass.className = :className " +
                "  AND objectId = :objectId",
                [className: oid.type,
                 objectId: oid.identifier])[0]
        }

但是mongodb gorm插件不支持hql，所以你的代码陷入hql错误的调用路径是这样的:

aclUtilService.addPermission -> aclService.createAcl -> retrieveObjectIdentity

还有另外两个使用 hql 的 aclService 方法:

deleteEntries, findChildren

因此，一个简单的解决方案是将 ACL 对象存储在 mysql 和 enable hibernate working with mongodb gorm 中。 .

另一个是用 meta programming 覆盖这 3 个 aclService 方法.
