如何按组名查找分组

Question

如何按组名查找com.liferay.portal.model.Group个对象？另外如何按角色名称查找com.liferay.portal.model.Role？

============= EDIT ===============

我有testGroup：

Group group = GroupServiceUtil.getGroup(themeDisplay.getCompanyId(), "testGroup");

结果：

11:09:09,858 ERROR [RuntimePageImpl-15][render_portlet_jsp:132] null
com.liferay.portal.NoSuchGroupException: No Group exists with the key {companyId=10157, name=testGroup}

您可以使用以下API方法按名称查找组和角色：

  GroupLocalServiceUtil.getGroup(long companyId, java.lang.String name)

  RoleLocalServiceUtil.getRole(long companyId, java.lang.String name)
