在struts后台代码

XXXXX 对象  get/set略。

struts提供的 类型拦截器会自动 赋值给XXX对象


@Action(value = SAVE_AJAX_ACTION)
	public void save() {
		 PrintWriter pw;
		try {
//这句必须有否则，返回前台的对象是 dom objcet.		
ServletActionContext.getResponse().setContentType("text/html;charset=UTF-8");

			pw = ServletActionContext.getResponse().getWriter();
			if(null != businessMsg){
				businessMsg.setMsgIp(Util.getConsumerIP(ServletActionContext.getRequest()));
				businessMsg.setMsgCreated(new Date());
				businessMsg.setMsgRead(0);
				businessMsg.setMsgDelete(0);
				businessMsg.setMsgDnd(0);
				businessMsgManager.save(businessMsg);
				pw.write("success");
			}else{
				pw.write("error");
			}
		} catch (IOException e) {
			log.error("bus_msg_save is error!",e);
		}
		
	}

ps: 目前没找到 josn直接转换成 struts 前后java对象的方法?哪位高手可指导下？
