# 1、问题描述 #

主要就是这句异常：`There is no PasswordEncoder mapped for the id "null"`

# 2、问题分析 #

这是由于没有密码加密器导致的。

![在这里插入图片描述][20200508210459474.png]  
这是问题代码，直接加上加密器就可以了。

# 3、问题解决 #

修改代码如下：

@Autowired
        public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { 
            auth.userDetailsService(userDetailsService).passwordEncoder(new MyPasswordEncoder());
        }

![在这里插入图片描述][20200508210510270.png]

> MyPasswordEncoder 啥都没做，只是继承了PasswordEncoder

package com.example.springsecurity.password;
    
    import org.springframework.security.crypto.password.PasswordEncoder;
    
    /** * @author Chen * @version 1.0 * @date 2020/5/8 20:54 * @description: */
    public class MyPasswordEncoder implements PasswordEncoder { 
        @Override
        public String encode(CharSequence charSequence) { 
            return charSequence.toString();
        }
    
        @Override
        public boolean matches(CharSequence charSequence, String s) { 
            return s.equals(charSequence.toString());
        }
    
    }

再次运行。

成功查看数据。

# 4、总结 #

书上的代码直接运行绝大部分是对的，但是总有一些软件的更新使得作者无能为力。之前的API是对的，但是之后就废弃了或修改了是常有的事。所以我们需要跟踪源代码。这只是一个小小的问题，如果没有前辈的无私奉献，很难想象我们自己一天能学到多少内容。感谢各位前辈的辛勤付出，让我们少走了很多的弯路！
