java.lang.IllegalStateException : When using WebSecurityConfigurerAdapter

Question

In Spring security when I am using WebSecurityConfigurerAdapter, throws the following error. Anyone can explain why what's wrong in the above configuration file.

1. 我仅在使用 WebSecurityConfigurerAdapter 时才得到
2. 不知道需要配置哪个方法

Answer 1

它提示由以下原因引起:java.lang.ClassNotFoundException:javax.servlet.Filter。 javax.servlet.Filter通常用于嵌入式tomcat，如果你没有尝试添加spring-boot-starter-web。如果有的话，请重新加载所有依赖项。如果您仍然遇到问题，请从本地存储库中删除 spring 依赖项并再次安装它们(我知道这是一个肮脏的解决方法)。
