Cannot forward after response has been committed问题 try {
PrintWriter out = response.getWriter();
//输出
out.print("用户名或密码错误！");
//out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
改了之后就是这样了
try {
PrintWriter out = response.getWriter();
//输出
out.print("用户名或密码错误！");
//out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}改了之后就是这样了
