当我点击提交按钮时，SaveServlet正在下载，如图所示，但是插入了值并且页面没有刷新/休息：

when i click on submit button SaveServlet is downloading like show in the IMG but values are inserted and page is not refersh/rested

Answer 1

尝试使用

<input type="submit" value="submit" name="submit"/>

当我点击提交按钮时，它不会去servlet页面下载该页面的原因

SaveServlet代码，我使用了注释
