微信公众号开发（2）——文本消息、图文消息发送

接上一讲，微信公众号开发（1）——服务器配置

新建几个信息类：

package com.imooc.po;

/**
 * 信息基类
 * @author lyj
 *
 */
public class BaseMessage {

	private String ToUserName;
	private String FromUserName;
	private Long CreateTime;
	private String MsgType;
	public String getToUserName() {
		return ToUserName;
	}
	public void setToUserName(String toUserName) {
		ToUserName = toUserName;
	}
	public String getFromUserName() {
		return FromUserName;
	}
	public void setFromUserName(String fromUserName) {
		FromUserName = fromUserName;
	}
	public Long getCreateTime() {
		return CreateTime;
	}
	public void setCreateTime(Long createTime) {
		CreateTime = createTime;
	}
	public String getMsgType() {
		return MsgType;
	}
	public void setMsgType(String msgType) {
		MsgType = msgType;
	}
	
}

package com.imooc.po;

/**
 * 文本消息类封装
 * @author lyj
 *
 */
public class TextMessage extends BaseMessage{

	private String Content;
	private String MsgId;
	
	public String getContent() {
		return Content;
	}
	public void setContent(String content) {
		Content = content;
	}
	public String getMsgId() {
		return MsgId;
	}
	public void setMsgId(String msgId) {
		MsgId = msgId;
	}
	
	
}

package com.imooc.po;

/**
 * 图文消息类
 * @author lyj
 *
 */
public class News {

	private String Title;
	private String Description;
	private String PicUrl;
	private String Url;
	public String getTitle() {
		return Title;
	}
	public void setTitle(String title)
