本文分享了解决Servlet中405错误的方法，包括检查web.xml中的class路径一致性、确保servlet方法正确重写doGet/doPost以及启用Eclipse的自动编译功能。

新手刚入门，写第一个小测试就是碰到了这个问题，搞了我几个小时才找到解决办法，现在将自己的解决思路整理一下：
报错的很明显，找不到对定的servlet方法，从下面三个方面找原因：
1、web.xml配置文件的class路径是否一致
!这里ctrl+鼠标可以点开说明路劲是对的](https://img-blog.csdnimg.cn/20190719150906207.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21vb25saW5naA==,size_16,color_FFFFFF,t_70)

2、对应的servlet方法中是否重写了doget和dopost方式，注意重写方法中不能有super.doget()或者super.dopost(),父类方法默认返回405

3、eclipse的设置成自动编译成class文件，否则就算有servlet或者修改了servlet都会看不到效果，设置方法是project 下的build Automatically前打上勾勾
