对于(int i=0;i应该很简单。替换为:

user.getPassword().equals(password)
用这个

encoder.matches(password, user.getPassword())

为什么要使用
CustomAuthenticationProvider
?您唯一需要的是custom
UserDetailsService
实现,其余部分可以使用Spring Security来完成!现在,我似乎不需要custom AuthenticationProvider,但我将来需要它;因为这样,我正在找到一个可以保存它的解决方案。如果您不需要它,也不需要构建它…最好的可维护代码是未编写的代码!一般来说,您不需要自定义的
AuthenticationProvider
,但可以实现一些协作类,而不是自己完成所有工作。但是,遗憾的是,您的bean与其他bean一样,只是创建一个属性并将其添加到然后我在CustomAuthenticationProvider中做了此更改,并添加了实现PasswordEncoder的a类BCryptPasswordEncoder(如下所示的示例)现在我面临错误java.lang.IllegalArgumentException:在我通知我的客户并尝试登录系统后,salt版本无效。有什么办法解决这个问题吗?好的,然后我开始解决这个特定错误,但我还不能登录系统。在我的数据库中,我的密码用MD5加密,我认为代码没有“不要将密码编码为Md5。我说的对吗?如果是,如何更正?”?
