There is no PasswordEncoder mapped for the id "null" || Encoded password does not look like BCryp

There is no PasswordEncoder mapped for the id "null"

官方查阅spring security 5.0 版本后新增PasswordEncoder多种加密方式,也改变加密格式

  • 现如今Spring Security中密码的存储格式是“{id}…………”。前面的id是加密方式,id可以是bcrypt、sha256等,后面跟着的是加密后的密码。也就是说,程序拿到传过来的密码的时候,会首先查找被“{”和“}”包括起来的id,来确定后面的密码是被怎么样加密的,如果找不到就认为id是null。这也就是为什么我们的程序会报错:There is no PasswordEncoder mapped for the id “null”。

  • 解决方法

  • 在配置类中WebSercurityConfig中修改
    方式1:
    There is no PasswordEncoder mapped for the id "null" || Encoded password does not look like BCryp
    方式2:
    There is no PasswordEncoder mapped for the id "null" || Encoded password does not look like BCryp

Encoded password does not look like BCryp

存入密码时需要对密码进行加密:
.password(passwordEncoder().encode(“password”))
