查看了很多文章，找到一个有效的解决办法：如下

使用ajax时，form表单提交按钮就没必要设置为submit类型，使用普通的button类型就行了，否则会出现以上错误信息

问题原因：<button>在Internet Explorer 的默认类型是 "button"，而其他浏览器中（包括 W3C 规范）的默认值是 "submit"。

所以导致了表单重复提交。出现“java.io.IOException: 你的主机中的软件中止了一个已建立的连接”异常。

问题解决：把代码 改为<button type="button" οnclick="addOrUPdate()">保存</button>，为<button>按钮定义Type属性为button。
