如何自定义Liferay 7 portal的Log in登录界面

前提:

1. Liferay portal 7

2. Liferay IDE 3.0.1

Liferay现有的工具中提供了很多修改portal的模板，以满足开发者的各种自定义需求。

修改的原理是利用Module小模块嵌到原来的代码中去，只是相当于打了一个补丁，并不会修改portal的源码，所以说是一种安全简单的方法。

步骤：

1. 新建一个Liferay Mudule Fragment Project(在选择HOST OSGi Bundle时选择com.liferay.login.web-version.jar,选择Override File Path点击Liferay蓝色的小图标选择META-INF/resources/login.jsp)

2.Click finish. 然后修改相应的jsp文件，改成你想要的界面，我只是做了一些小修改，看代码：

3.部署到Lifeay Portal上就可以看到你想要的效果啦，下面是效果图：

完工啦，以后会陆续更新其他模板的使用，发现有好多模板呀，咦，还有一些我也不会用，还好，我们组里有一群大神，哈哈
