/**
 * FastBootWeixin WxSyncMessageReturnValueHandler
 * 其实@WxAsyncMessage并不是通过这个类发送的，这里应该叫做CustomerMessage，这里的消息不需要异步发送，直接调用发送即可
 * todo 按照上面的逻辑重构
 * done 已重构
 * 该类不处理声明为被动返回的消息，即返回XML消息，其他类型都通过本类处理
 * 而对于消息的发送，都采用异步的方式我觉得没有问题，如果同步发送，报错之后响应给微信，微信会返回给用户服务器故障，这是不友好的，所以这里固定异步发送。
 * 但是有点区别，如果是普通的@RequestMapping呢，可能就不需要异步发送了
 * todo 分离出来两种，WxMappingReturnValueHandler和WxMessageReturnValueHandler
