微信公众号开发--基于WxJava （微信开发 Java SDK）框架的，客服消息推送实现

主动发送客服消息，示例：

            // 客服消息、图文消息
			// 图文消息1
			WxMpKefuMessage.WxArticle article1 = new WxMpKefuMessage.WxArticle();
			article1.setUrl("http://xial9527.w3.luyouxia.net/wx/jsp/login.html");
			article1.setPicUrl("http://test.iwocloud.com/wx/images/index_bg.png");
			article1.setDescription("今天天气很好，适合出去玩");
			article1.setTitle("测试测试测试一下啦啦啦");
			// 图文消息2
			WxMpKefuMessage.WxArticle article2 = new WxMpKefuMessage.WxArticle();
			article2.setUrl("http://xial9527.w3.luyouxia.net/wx/index?code=1YF00137");
			article2.setPicUrl("http://test.iwocloud.com/wx/images/index_bg.png");
			article2.setDescription("晚上去吃火锅吧，逛超市");
			article2.setTitle("今日安排");
			// 封装 xml
			WxMpKefuMessage wxMpKefuMessage = WxMpKefuMessage.NEWS()
			    .toUser("otAIM6PimOuARRXXTWcloLL-XLU0")
			    .addArticle(article1)
			    //.addArticle(article2)
			    .build();
			// 发送给指定openid
			wxMpService.getKefuService().sendKefuMessage(wxMpKefuMessage);
