Question

我正在尝试使用类addGroup的方法GroupLocalServiceUtil在Liferay中创建一个新组。我根据文档传递参数类型，但它会莫名其妙地抛出IllegalArgumentException。这是我的简单代码：

ServiceContext sc = new ServiceContext();
sc.setScopeGroupId(10);
GroupLocalServiceUtil.addGroup(11101, "com.liferay.portal.model.Group", 0, 0, "aaa","foo", description, 
            10, null, true, true, sc);

有什么问题？我可以将ServiceContext参数设置为null吗？

更新：我使用的版本是6.1。 Exception的堆栈跟踪是：

Answer 1

我正在使用 Liferay 6.1.1 ，并在GroupLocalServiceImpl.addGroup中查看第276行，我可以看到：

if (className.equals(Group.class.getName())) {
    if (!site && (liveGroupId == 0)) {
        throw new IllegalArgumentException(); // this is line 276
    }
}

因此，您必须设置site=false和liveGroupId=0。

无论如何，我曾经使用这段代码来创建网站（我重复一遍， Liferay 6.1.1 ），就我记忆中而言它完美无缺;）

GroupLocalServiceUtil.addGroup(userId, Group.class.getName(), 0, "title","description",GroupConstants.TYPE_SITE_OPEN, "/siteFriendlyUrl", true, true, new ServiceContext());

Answer 2

您确定url可以为空吗？
你能用Group.class.getName（）吗？
