微信企业号OAuth2验证接口(使用SpringMVC)具体处理流程如下图：
此处源码包括：微信企业号的接入及消息的简单处理，在此基础上添加OAuth2的验证实例。

具体实现代码：
创建拦截器：OAuth2Interceptor

public class OAuth2Interceptor implements HandlerInterceptor {
/**
* 在DispatcherServlet完全处理完请求后被调用
* 当有拦截器抛出异常时,会从当前拦截器往回执行所有的拦截器的afterCompletion()
*/
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
System.out.println("**执行顺序: 3、afterCompletion**");
}
/**
* 在业务处理器处理请求执行完成后,生成视图之前执行的动作
*/
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object arg2, ModelAndView modelAndView) throws Exception {
System.out.println("**执行顺序: 2、postHandle**");
}
/**
* 在业务处理器处理请求之前被调用 如果返回false 从当前的拦截器往回执行所有拦截器的afterCompletion(),再退出拦截器链
* 如果返回true 执行下一个拦截器,直到所有的拦截器都执行完毕 再执行被拦截的Controller 然后进入拦截器链,

微信企业号调用类 {"errcode":0,"errmsg":"ok"} 此结果表示调用方法成功返回QiYeUtil.class
返回结果处理类Result.class
枚举EnumMethod.class
