response 返回js的alert()语句，中文乱码如何解决，

步骤1：在后台加上如下代码：

response.setCharacterEncoding("utf-8");

response.setContentType("text/html;charset=utf-8;");

完整参考代码如下：

response.setCharacterEncoding("utf-8");

response.setContentType("text/html;charset=utf-8;");

PrintWriter writer=response.getWriter();
writer.write(
"<script type=\"text/javascript\">alert('您踢出，即将跳到登录界面...');setInterval(\"\",1000);parent.location.href='" + ctxPath
+ "/user/loginJsp.action'</script>");
writer.flush();
writer.close();
