原生JavaWeb使用response的中文乱码问题 继承HttpServlet后重写方法时加入两行代码设置utf-8编码 详细如下示例
代码语言：javascript复制 resp.setContentType("application/json;charset=utf-8");
resp.setCharacterEncoding("utf-8");
//需要加上方法的最上面,也就是在方法内容的首位.完整示例：
代码语言：javascript复制 protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
resp.setContentType("application/json;charset=utf-8");
resp.setCharacterEncoding("utf-8");
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<HTML>");
out.println("<HEAD><TITLE>Hello World</TITLE></HEAD>");
out.println("<BODY>");
out.println("关键就是最上面两行代码,用于设置编号");
out.println("</BODY></HTML>");
}
