DWR做反推时出现乱码，解决办法：

1. 在服务器反推前进行编码，代码如下：

		// 进行编码， 防止乱码
		String msg = "这该死的乱码啊";
		try {
			msg = URLEncoder.encode(msg,"UTF-8");
		} catch (UnsupportedEncodingException e1) {
			e1.printStackTrace();
		}
		

function showMessage(data) {
	var message = decodeURI(data.msg); // 解码
	var text = dwr.util.getValue("info");
	if (!!text) {
		dwr.util.setValue("info",text + "\n" + data.time + "  " + message);
	} else {
		dwr.util.setValue("info",data.time + "  " + message);
	}
}
