SpringBoot-Security密码加密

1 密码是需要加密后密码加盐存入数据库的，使用散列函数

2 SpringBoot中使用BCryptPasswordEncoder 进行加密 且相同密码产生的密文也不相同

    @Test
    void contextLoads() {
        for (int i = 0; i < 10; i++) {
            BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
            System.out.println(encoder.encode("123"));
        }
    }

输出结果:

Security中的使用：

    @Bean
    PasswordEncoder passwordEncoder(){
        // 这里返回BCryptPasswordEncoder的对象
        return new BCryptPasswordEncoder();
    }

    @Autowired
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("uuc").password("$2a$10$vW1WJmu9uezXFSylWPmYluJugi8AtUurOQ3FK/RwYvTfR5bDZNZTm").roles("admin")
                .and()
                .withUser("akk").password("$2a$10$Q9vj2K3gwiFvmvq.LmIYsOJ/JXWIQu7nQZER6h0duCFaOYnbnvz5W").roles("user");
    }
