Spring Security 报：Encoded password does not look like BCrypt

Posted 2023-04-27 VipSoft

SpringBoot 集成 Security 时，报 Encoded password does not look like BCrypt
原因：SecurityConfig 必须 Bean 的形式实例化

/**
 * 配置用户身份的configure()方法
 *
 * @param auth
 * @throws Exception
 */
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception 
    auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder());

解决方案

/**
 * 强散列哈希加密实现 
 * 必须 Bean 的形式实例化，否则会报 ：Encoded password does not look like BCrypt
 */
@Bean
public BCryptPasswordEncoder bCryptPasswordEncoder()

    return new BCryptPasswordEncoder();


/**
 * 配置用户身份的configure()方法
 *
 * @param auth
 * @throws Exception
 */
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception 
    auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder());

spring security 登陆报错java.lang.StackOverflowError: null？

@Bean
public AuthenticationManager authenticationManager() throws Exception
return super.authenticationManagerBean();

加上这个叫报登陆时就报异常
java.lang.StackOverflowError: null

这是一部分

参考技术A 有变量未初始化，就使用
