void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException //如果浏览器直接请求发送doget
void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException //当form表单发送psot请求时,调用doPost
void service(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException //既能处理get又能处理post请求
当发送doget请求,只有doPost方法程序会报405
解决:
@Override
protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}
