密码加密存储

定义一个SpringSecurity的配置类，SpringSecurity要求这个配置类要继承WebSecurityConfigurerAdapter。

package com.security.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {


    @Bean
    public PasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }

}

登录错误，提示用户名密码错误
