我正在尝试使用散列密码填充数据库，然后通过匹配我通过登录表单提交的数据来登录我的应用程序，就像典型的散列密码应该如何工作一样。我正在使用 spring security 和 spring boot，到目前为止，我知道登录表单正在工作，因为我收到了 error Encoded password does not look like BCrypt。而且我知道当我将用户提交到数据库时它不起作用，因为我只是在数据库的密码列中看到一个纯字符串。我真的不确定我要去哪里错了。
这是我的用户对象

这是我的安全配置

我的用户详情服务

// Build user's authorities
for (UserRole userRole : userRoles) {
setAuths.add(new SimpleGrantedAuthority(userRole.getRoleName()));
}
return new ArrayList<GrantedAuthority>(setAuths);
}
}
和密码加密
package com.example.security;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.crypto.password.PasswordEncoder;
public class PasswordCrypto {
@Autowired
private PasswordEncoder passwordEncoder;
private static PasswordCrypto instance;
public static PasswordCrypto getInstance() {
if(instance == null) {
instance = new PasswordCrypto();
}
return instance;
}
public String encrypt(String str) {
return passwordEncoder.encode(str);
}
}
如果有人知道我做错了什么并且可以帮助我，那就太好了，如果我需要显示更多代码，请告诉我。提前致谢。
