Liferay 中的 portlet 迁移答案

【问题标题】：Migration of portlets in LiferayLiferay 中的 portlet 迁移
【发布时间】：2015-06-04 05:57:45
【问题描述】：

我必须将 Liferay 6.1 ga2 中的 portlet 部署到 Liferay 6.1 ga3。

我已经尝试过这样做，但它没有被部署。数据库连接完成。 Web 内容正在显示，但 Portlet 部分显示“Portlet 未部署。请重新部署它。”

我是 Liferay 的新手。谁能一步步指导我？

提前致谢。

这是日志：

【问题讨论】：

请提供控制台错误@portlet 部署时间
我会在启动另一台服务器后立即提供日志。但我从之前的日志中记得，存在一些库问题。无论如何，应该尽快发布日志。
我刚查了一下，有一个.properties文件同名但没有.xml文件。
你在属性文件中找到了什么？这可能很明显。无论如何，当您知道的不仅仅是“我有问题”时，让我们继续 - 例如。当您从日志文件中发布实际消息时。到目前为止，这还没有足够的信息

标签： liferay

【解决方案1】：

这是我的方式：

使用 Liferay sdk 6.1.2 创建具有相同名称的新 portlet。
将您的代码、html、资源、库从旧 portlet 复制到新 portlet。
将portlet.xml、liferay-portlet.xml 和liferay-display.xml 中的portlet 声明从旧portlet 复制到新portlet（不要覆盖这些文件）。
部署新的 portlet。

【讨论】：

【解决方案2】：

要遵循的 Portlet 升级步骤。

在 liferay-plugin-package.properties 文件中升级 liferay 的版本。（请注意 liferay-plugin-package.xml 文件是由 liferay 在运行时创建的）
升级liferay-display.xml、liferay-portlet.xml文件中对应的liferay DTD版本。（在某些情况下这是可选的）
根据新的 API 类/方法/参数等升级 portlet 代码。

如果仍然失败，请告诉我。

【讨论】：

看我都试过了。我一定会再做一次。我必须将我的整个项目迁移到另一台服务器。所以我真的无法对代码做任何事情。我会尝试检查我的 .xml 文件。
嗨。好吧，我尝试了一切，现在服务器日志给出了与数据库相关的错误。但是这个特殊的错误也得到了解决。尽管如此，服务器仍然显示相同的错误。
