//正确写法

response.setContentType("text/html");

request.setCharacterEncoding("utf-8");

response.setCharacterEncoding("utf-8");

PrintWriter out = response.getWriter();

//先设置编码，在用writer方法取出

//错误写法

PrintWriter out = response.getWriter();

request.setCharacterEncoding("utf-8");

response.setCharacterEncoding("utf-8");

//这样会报好多的错误
