java自动登入新浪微博-准备给JiveJdon增加一个关注提交微博功能

准备给JiveJdon增加一个关注提交微博功能，一个用户关注某个话题或作者，如果有更新java自动登入新浪微博，将更新内容提交其微博上java自动登入新浪微博，新浪微博使用OAuth认证，一般中间需要一个界面输入用户名和密码，因为是关注后自动激活提交，所以由程序自动提交，当然微博的用户和密码当用户决定关注话题时需要输入，并保存在jivejdon系统中，这是有一些风险。

在新浪微博原来的weibo案例中增加一些代码，直接运行WebAuth这个Application即可，前提是：

1. 将Weibo中的CONSUMER_KEY CONSUMER_SECRET替换成你注册新浪微博应用后给你的值。

2. 下面代码中替换你的新浪微博的用户名和密码。
