SpringBoot2.x整合Security5遇到的bug

问题

（There is no PasswordEncoder mapped for the id "null"）

• 显然这是密码认证问题,springboot1.x多版本都能使用,主要到后面就升级了,密码验证好多方法都改了,具体参考官方文档
  springboot官方文档
• 找到安全方面的模快,这里我就说一下我是如何解决的
• 原始代码

    return new org.springframework.security.core.userdetails.User(Long.toString(user.getId()),
        user.getPassword(), authorities);
  }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        super.configure(auth);
    }

• 修改后

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        //super.configure(auth);
      auth.userDetailsService(customUserService()).passwordEncoder(new BCryptPasswordEncoder());
    }

    return new org.springframework.security.core.userdetails.User(Long.toString(user.getId()),
        new BCryptPasswordEncoder().encode(user.getPassword()), authorities);
  }
