There is no PasswordEncoder mapped for the id "null"
springboot集成 spring-security认证报错--> There is no PasswordEncoder mapped for the id "null"
在网上看到说是 springboot 2.1.x之前可以直接使用,之后认证就会
There is no PasswordEncoder mapped for the id "null"
解决方案:
//认证 springboot 2.1.x 可以直接使用~ //密码编译,passwordEncoder //在spring security 5.0+ 新增了很多的加密方式~ 如果没有密码,会不让你使用,明文密码会遭受到反编译,不安全 @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { //这些数据正常应该是从数据库中读取 auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder()) .withUser("aaa")password(new BCryptPasswordEncoder().encode("123456")).roles("vip2","vip3")
.and()
.withUser("root").password("123456").roles("vip1","vip2","vip3")
.and()
.withUser("guest").password("123456").roles("vip1") ; }
