java - 我是否可以实例化 Journal Article 对象并在没有构造函数的情况下设置每个属性？

Question

当我这样做时，当我运行 build.xml 并部署时它不会编译，

我想这样做，因为它看起来比使用 JournalArticleLocalServiceUtil.addArticle 的巨大方法调用要好得多。

JournalArticle journalArticle = new JournalArticleImpl();
journalArticle.setDescription(description);

有人知道在 Liferay 6 中是否可行吗？

编辑:这是我得到的输出:

正如 Jon 提到的，如果您使用的是插件 SDK，则不会复制实现类的库/jar。不幸的是，您不能直接从插件创建 JournalArticle 对象，您必须使用 JournalArticleLocalServiceUtil 来创建对象。
