response.getWriter().write 乱码问题 解决方案
最近在使用response.getWriter().write()方法向页面返回一个上传文件的名字时，当文件名字中出现中文，页面显示乱码。代码如下：
response.getWriter().write(“中文”);
最后在调用response.getWriter()之前添加这句话解决问题：
response.setContentType("text/html;charset=UTF-8");
response.getWriter().write(“中文”）;
案例：
- protected void doGet(HttpServletRequest request, HttpServletResponse response)
- throws ServletException, IOException {
- System.out.println("测试");
- response.setContentType("text/html;charset=UTF-8"); //这里写入防止乱码
- response.getWriter().write("<a href='https://javar.cc'>JAVA编程好爱者</a>");
- }
- protected void doPost(HttpServletRequest request, HttpServletResponse response)
- throws ServletException, IOException {
- request. setCharacterEncoding("UTF-8");//这里写入防止乱码
- doGet(request, response);
- }
