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);
}
}
