"本文档介绍了在Spring Security中遇到的一个错误：ThereisnoPasswordEncodermappedfortheid“null”。该错误源于Spring Security 5.0以后默认密码编码器的改变。解决方案是在配置中添加'{noop}

问题描述：There was an unexpected error (type=Internal Server Error, status=500). There is no PasswordEncoder mapped for the id “null” java.lang.IllegalArgumentException: There is no PasswordEncoder mapped for the id “null”

发送包含用户名和密码的GET请求，在登陆界面输入用户名没问题，但是输入密码后跳转页面报错：There is no PasswordEncoder mapped for the id “null”

这是我的config文件

/**
 * security configuration class
 */
@EnableWebSecurity

public class SecurityConfig extends WebSecurityConfigurerAdapter {
   
   

    @Override
    protected void configure(HttpSecurity http) throws Exception{
   
   

        http.
