微信公众号开发学习

微信公众号开发学习

1、Readme说明：微信公众号平台开发最好用PHP，但Java也是可以实现的，下面代码用Java语言演示了HttpURLConnection的使用，成为公众号开发者，接收微信公众号信息，响应文本消息，发布菜单，获取用户基本信息等操作。

下面会给出供参考的程序源代码。

 

2、XStream简单介绍：

（1）XStream可以将Java对象和xml文档之间相互转换，而且可以修改某个特定的属性和节点名称，而且也支持json的转换。

（2）Java到xml，用toXML()方法。

Xml到Java，用fromXML()方法。

（3）在没有任何设置默认情况下，Java到xml的映射，是Java成员名对应xml的元素名，Java类的全名对应xml根元素的名字。而实际中，往往是xml和java类都有了，需要相互转换，必须进行别名映射。

（4）别名配置包括三种情况：

①类别名，用alias（String name，Class type）

②类成员别名，用aliasField（String alias，Class definedIn，String fieldName）

③类成员作为属性别名，用aliasAttribute（Class definedIn，String attributeName，String alias），单独命名没有意义，还要通过useAttributeFor（Class definedIn，String fieldName）应用到某个类上。

3、下面是包及类的关系图：
