Java 将Spring配置为使用数据库进行身份验证

我想将Spring安全性配置为将数据库用于RESTAPI请求。我试过这个:

    @Configuration
    @EnableWebSecurity
    @Import(value= {Application.class, ContextDatasource.class})
    @ComponentScan(basePackages= {"org.rest.api.server.*"})
    public class ApplicationSecurityConfig extends WebSecurityConfigurerAdapter {

        @Autowired 
        private RestAuthEntryPoint authenticationEntryPoint;

        @Autowired
        MyUserDetailsService myUserDetailsService;

        @Autowired
        public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    //      auth
    //      .inMemoryAuthentication()
    //      .withUser("test")
    //      .password(passwordEncoder().encode("testpwd"))
    //      .authorities("ROLE_USER");
            auth.userDetailsService(myUserDetailsService);
            auth.authenticationProvider(authenticationProvider());
        }
        @Bean
        public DaoAuthenticationProvider authenticationProvider() {
            DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();
            authenticationProvider.setUserDetailsService(myUserDetailsService);
            authenticationProvider.setPasswordEncoder(passwordEncoder());
            return authenticationProvider;
        }
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
            .authorizeRequests()
            .antMatchers("/securityNone")
            .permitAll()
            .anyRequest()
            .authenticated()
            .and()
            .httpBasic()
            .authenticationEntryPoint(authenticationEntryPoint);
        }
        @Bean
        public PasswordEncoder passwordEncoder() {
            return NoOpPasswordEncoder.getInstance();
        }
    }
服务:

    public interface MerchantsService {

        public Merchants getCredentials(String login, String pwd) throws Exception;
    }
服务实现

@Service
@Qualifier("merchantsService")
@Transactional
public class MerchantsServiceImpl implements MerchantsService {

    @Autowired
    private EntityManager entityManager;

    @Override
    public Merchants getCredentials(String login, String pwd) throws Exception {
        String hql = "select e from " + Merchants.class.getName() + " e where e.login = ? and e.pwd = ?";

        Query query = entityManager.createQuery(hql).setParameter(0, login).setParameter(1, pwd);
        Merchants merchants = (Merchants) query.getSingleResult();

        return merchants;
    }
}



    @Service
    public class MyUserDetailsService implements UserDetailsService {

        @Autowired
        private MerchantsService merchantsService;

        @Override
        public Merchants loadUserByUsername(String username) {
            Merchants user = merchantsService.getCredentials(username, pwd);
            if (user == null) {
                throw new UsernameNotFoundException(username);
            }
            return user;
        }
    }
我有两个问题:

  • 如何使用Merchant对象,但Spring接受对象UserDetails。如何实现此功能

  • 如何使用用户名和密码验证请求。我看到
    public UserDetails loadUserByUsername(字符串用户名)
    只能接受用户名。有没有其他方法来实现代码


  • 您必须返回
    User
    class对象,它本身就是UserDetails接口的实现。获得身份验证后,您将获得一个对象。您必须从中获取用户凭据以及角色。还有一个建议,尽量保持类名为单数

    public UserDetails loadUserByUsername(String username) {
     Merchants user = merchantsService.getCredentials(username, pwd);
    
            Set<GrantedAuthority> grantedAuthorities = new HashSet<>();
            for (Role role : user.getRoles()){
                grantedAuthorities.add(new SimpleGrantedAuthority(role.getName()));
            }
    
            return new User(user.getUsername(), user.getPassword(), grantedAuthorities);
    }
    
    public UserDetails loadUserByUsername(字符串用户名){
    商户用户=merchantsService.getCredentials(用户名,pwd);
    Set grantedAuthories=new HashSet();
    for(角色:user.getRoles()){
    添加(新的SimpleGrantedAuthority(role.getName());
    }
    返回新用户(User.getUsername()、User.getPassword()、GrantedAuthories);
    }
    
    您不需要做密码匹配自己,它是由Spring Security自己使用PasswordEncoder完成的

    有关更多详细信息,请浏览以下链接。

    使用Spring Security时,必须实现一个服务,该服务实现UserDetails服务和相应的loadUserByUsername方法,该方法返回UserDetails。以下是一个示例方法:

    @Override
      public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = this.getUserByUsername(username); // getting the user from the database with our own method
        return new org.springframework.security.core.userdetails.User(user.getUsername(), user.getPassword(), new ArrayList<>());
      }
    
    @覆盖
    public UserDetails loadUserByUsername(字符串用户名)引发UsernameNotFoundException{
    User User=this.getUserByUsername(username);//使用我们自己的方法从数据库中获取用户
    返回新的org.springframework.security.core.userdetails.User(User.getUsername(),User.getPassword(),new ArrayList());
    }
    

    您不必担心验证密码,因为spring security会处理它。

    这就是您想要的吗?这个例子有两个问题:1:我没有角色,因为根据业务需求,没有必要——所以我们需要删除它。2:我需要在身份验证中包含密码。
