Spring Security 报There is no Pas

查了下发现是spring security 版本在5.0后就要加个PasswordEncoder了

解决办法

1. 在securityConfig类下加入NoOpPasswordEncoder，不过官方已经不推荐了

    @Bean
    public static NoOpPasswordEncoder passwordEncoder() {
        return (NoOpPasswordEncoder) NoOpPasswordEncoder.getInstance();
    }

2. 在securityConfig类下加入密码加密,在数据库中存的密码也是要经过这个加密的才能匹配上

    @Autowired
    private UserDetailsService customUserService;

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

补充：加密操作

    public static void main(String[] args) {
        BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();
        //加密"0"
        String encode = bCryptPasswordEncoder.encode("0");
        System.out.println(encode);
        //结果：$2a$10$/eEV4X7hXPzYGzOLXfCizu6h7iRisp7I116wPA3P9uRcHAKJyY4TK
    }
