@启动组件时未调用激活

Liferay's documentation about making modules configurable

@Component(configurationPid = "myproject.api.TranslationConfiguration")
public class TranslationServiceImpl implements TranslationService {
    private volatile TranslationConfiguration configuration;

    public TranslationServiceImpl() {
        log.info("TranslationServiceImpl constructor");
    }

    @Activate
    @Modified
    protected void activate(Map<String, Object> properties) {
        log.info("Hello from activate");
    }
}

部署时,日志仅显示:

TranslationServiceImpl constructor
Service registered.
STARTED myproject.impl_1.0.0 [538]

为什么是 activate 方法未调用?

重新启动Gogo Shell中的模块不会调用 使活动 任何一个
