SpringWebSecurity:错误原因的错误凭证

标签: spring spring-security

我有一个非常简单的基于SpringSecurity的身份验证系统,与here发现的https://www.google.com/webmasters/tools/home?hl=en非常相似(稍微复杂一些)。

然而,当我执行登录过程时,SpringSecurity会根据其配置抛出Bad Credentials错误。

查看代码,我无法找到原因,因为在运行时用户名,密码,启用和角色都是根据存储在DB中的内容。因此,我认为它可能来自错误的配置或逻辑问题。

根据日志,唯一可能失败的是:WARNING: Encoded password does not look like BCrypt,但我读到每次认证都是正常的。

有人可以帮我检查配置吗?谢谢!

答案 0 :(得分:0)

经过一番研究,我发现了这个问题。我正在处理第三方提供的已经输入的密码。因此,我将它直接存储在DB中,而SpringSecurity正在使用自己的加密(BCrypt)。因此,SpringSecurity与两个不同的编写字符串相比,产生了问题(在问题中提到的警告消息中给出了一个很好的提示)。

这样,我在AppSecurityConfig中禁用了@Bean PasswordEncoder,因为没有必要保留它(请记住我已经在处理预先输入的密码)。在那之后,事情很好。
