Struts2使用response发送中文时乱码
在网上搜索了半天，无果，
先修改了struts.properties
struts.i18n.encoding=UTF-8
无果，又修改以下代码
PrintWriter out=response.getWriter();
response.setCharacterEncoding("GBK");
response.setContentType("text/html;charset=GBK;");
正确解决方法：
HttpServletResponse response = ServletActionContext.getResponse();
response.setCharacterEncoding("GBK");
response.setContentType("text/html;charset=GBK;");
PrintWriter out=response.getWriter();
out.print("中国好。。。");
//out.println(Php.showMsg("您输入验证码有误！", "-1"));
out.close();
return null;
一定要在PrintWriter out=response.getWriter(); 之前设置好
response.setCharacterEncoding("GBK");
response.setContentType("text/html;charset=GBK;");
