Spring Security 设置登录的用户名和密码的三种方式

Posted 2022-02-14 hellodev

第一种方式：通过配置文件

spring:
  security:
    user:
      name: root
      password: root

第二种方式：通过配置类

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter 

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception 
        BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
        String encode = passwordEncoder.encode("123");
        auth.inMemoryAuthentication().withUser("root").password(encode).roles("admin");
    

    @Bean
    PasswordEncoder passwordEncoder() 
        return new BCryptPasswordEncoder();
    

第三种方式：自定义编写实现类

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter 

    @Autowired
    private UserDetailsService userDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception 
        auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
    

    @Bean
    PasswordEncoder passwordEncoder() 
        return new BCryptPasswordEncoder();
    

@Service("userDetailsService")
public class MyUserDetailsService implements UserDetailsService 
    @Override
    public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException 
        List<GrantedAuthority> authorityList = AuthorityUtils.commaSeparatedStringToAuthorityList("role");
        return new User("root", new BCryptPasswordEncoder().encode("123"), authorityList);
