同学你好，这里可以新建一个doGet方法，在doGet方法中调用doPost方法，如：
然后重启项目再试试。
如果还有报错，请将新的报错贴一下。
祝：学习愉快~

我把doGet方法改为doPost方法和doPost方法改为doGet方法都试过了，重新建了servlet也报错

同学你好，这里我们是通过地址栏访问的http://localhost:8080/employee/es该链接，建议同学将doPost方法改为doGet，或者在doGet方法中调用doPost
另外，还有个小建议，当类名由一个单词组成时，该单词首字母大写；如果类名由多个单词组成，则每个单词的首字母均大写。如：employee应改为：Employee，newEmployee应改为NewEmployee
如果我的回答解决了你的疑惑，请采纳！祝学习愉快！
