我有一个场景，我有一个类和一些方法，我需要在我的主题中的 liferay 速度模板中访问它们。
我尝试vm使用
#set ($myService = $serviceLocator.findService('my-dummy-portlet', 'com.mycompany.dummy.DummyABC'))
对于以下课程 -
final class DummyABC {
public String method1() {}
public String method2() {}
public String method3() {}
}
但我得到以下异常 -
07:17:22,303 ERROR [PortletBeanLocatorUtil:38] BeanLocator is null
07:17:22,304 ERROR [ServiceLocator:56] com.liferay.portal.kernel.bean.BeanLocatorException: BeanLocator has not been set
