java – Spring安全切换到Ldap认证和数据库权限

发布时间:2019-05-15 发布网站:脚本之家
脚本之家收集整理的这篇文章主要介绍了java – Spring安全切换到Ldap认证和数据库权限脚本之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我为我的网页和Web服务实现了数据库身份验证.
它对两者都很好,现在我必须添加Ldap身份验证.
我必须通过远程Ldap服务器进行身份验证(使用用户名和密码),如果用户存在我必须使用我的数据库为用户角色(在我的数据库用户名是相同的用户名Ldap).
所以我必须从我的实际代码切换到Ldap和数据库认证,如上所述.我的代码是:
SecurityConfig类
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true,prePostEnabled = true,proxyTargetClass = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    @Qualifier("userDetailsService")
    UserDetailsService userDetailsService;

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
    }

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

    @Configuration
    @Order(1)
    public static class ApiWebSecurityConfig extends WebSecurityConfigurerAdapter{
        @Override
        protected void configure(HttpSecurity http) throws Exception {
             http.csrf().disable()
             .antMatcher("/client/**")
             .authorizeRequests()
             .anyRequest().authenticated()
             .and()
             .httpBasic();
        }
    }

    @Configuration
    @Order(2)
    public static class FormWebSecurityConfig extends WebSecurityConfigurerAdapter{

        @Override
        public void configure(WebSecurity web) throws Exception {
            web
            //Spring Security ignores request to static resources such as CSS or JS files.
            .ignoring()
            .antMatchers("/static/**");
        }

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
            .authorizeRequests() //Authorize Request Configuration
                //the / and /register path are accepted without login
                //.antMatchers("/","/register").permitAll()
                //the /acquisition/** need admin role
                //.antMatchers("/acquisition/**").hasRole("ADMIN")
                //.and().exceptionHandling().accessDeniedPage("/Access_Denied");
                //all the path need authentication
                .anyRequest().authenticated()
                .and() //Login Form configuration for all others
            .formLogin()
                .loginPage("/login")
                //important because otherwise it goes in a loop because login page require authentication and authentication require login page
                    .permitAll()
            .and()
            .logout()
                .logoutSuccessUrl("/login?logout")
                .permitAll();
             // CSRF tokens handling
        }
    }

MyUserDetailsS​​ervice类

@Service("userDetailsService")
public class MyUserDetailsService implements UserDetailsService {

    @Autowired
    private UserServices userServices;
    static final Logger LOG = LoggerFactory.getLogger(MyUserDetailsService.class);

    @Transactional(readOnly=true)
    @Override
    public UserDetails loadUserByUsername(final String username){
        try{
            com.domain.User user = userServices.findById(username);
            if (user==null)
                LOG.error("Threw exception in MyUserDetailsService::loadUserByUsername : User doesn't exist" ); 
            else{
                List<GrantedAuthority> authorities = buildUserAuthority(user.getUserRole());
                return buildUserForAuthentication(user,authorities);
            }
        }catch(Exception e){
            LOG.error("Threw exception in MyUserDetailsService::loadUserByUsername : " + ErrorExceptionBuilder.buildErrorResponse(e));  }
        return null;
    }

    // Converts com.users.model.User user to
    // org.springframework.security.core.userdetails.User
    private User buildUserForAuthentication(com.domain.User user,List<GrantedAuthority> authorities) {
        return new User(user.getUsername(),user.getPassword(),user.isEnabled(),true,authorities);
    }

    private List<GrantedAuthority> buildUserAuthority(Set<UserRole> userRoles) {

        Set<GrantedAuthority> setAuths = new HashSet<GrantedAuthority>();

        // Build user's authorities
        for (UserRole userRole : userRoles) {
            setAuths.add(new SimpleGrantedAuthority(userRole.getUserRoleKeys().getRole()));
        }

        List<GrantedAuthority> Result = new ArrayList<GrantedAuthority>(setAuths);

        return Result;
    }

所以我必须要:

1)用户从网页的登录页面以及Web服务的用户名和密码访问用户.这必须通过Ldap完成.

2)用户需要用户名进行数据库查询来认证用户.
你有什么想法可以实现吗?
谢谢

使用正确的代码更新:遵循@M. Deinum建议我创建MyAuthoritiesPopulator类而不是MyUserDetailsS​​ervice,并使用数据库和Ldap进行身份验证:

@Service("myAuthPopulator")
public class MyAuthoritiesPopulator implements LdapAuthoritiesPopulator {

    @Autowired
    private UserServices userServices;
    static final Logger LOG = LoggerFactory.getLogger(MyAuthoritiesPopulator.class);

    @Transactional(readOnly=true)
    @Override
    public Collection<? extends GrantedAuthority> getGrantedAuthorities(DirContextOperations userData,String username) {
        Set<GrantedAuthority> authorities = new HashSet<GrantedAuthority>();
        try{
            com.domain.User user = userServices.findById(username);
            if (user==null)
                LOG.error("Threw exception in MyAuthoritiesPopulator::getGrantedAuthorities : User doesn't exist into ATS database" );  
            else{
                for(UserRole userRole : user.getUserRole()) {
                    authorities.add(new SimpleGrantedAuthority(userRole.getUserRoleKeys().getRole()));
                }
                return authorities;
            }
        }catch(Exception e){
            LOG.error("Threw exception in MyAuthoritiesPopulator::getGrantedAuthorities : " + ErrorExceptionBuilder.buildErrorResponse(e)); }
        return authorities;
    }
}

我更改了SecurityConfig如下:

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true,proxyTargetClass = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    @Qualifier("myAuthPopulator")
    LdapAuthoritiesPopulator myAuthPopulator;

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

         auth.ldapAuthentication()
          .contextSource()
            .url("ldap://127.0.0.1:10389/dc=example,dc=com")
//          .managerDn("")
//          .managerPassword("")
          .and()   
            .userSearchBase("ou=people")
            .userSearchFilter("(uid={0})")
            .ldapAuthoritiesPopulator(myAuthPopulator);     
    }

    @Configuration
    @Order(1)
    public static class ApiWebSecurityConfig extends WebSecurityConfigurerAdapter{
        @Override
        protected void configure(HttpSecurity http) throws Exception {
             http.csrf().disable()
             .antMatcher("/client/**")
             .authorizeRequests()
             //Excluede send file from authentication because it doesn't work with spring authentication
             //TODO add java authentication to send method
             .antMatchers(HttpMethod.POST,"/client/file").permitAll()
             .anyRequest().authenticated()
             .and()
             .httpBasic();
        }
    }

    @Configuration
    @Order(2)
    public static class FormWebSecurityConfig extends WebSecurityConfigurerAdapter{

        @Override
        public void configure(WebSecurity web) throws Exception {
            web
            //Spring Security ignores request to static resources such as CSS or JS files.
            .ignoring()
            .antMatchers("/static/**");
        }

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
            .authorizeRequests() //Authorize Request Configuration
                //the "/" and "/register" path are accepted without login
                //.antMatchers("/","/register").permitAll()
                //the /acquisition/** need admin role
                //.antMatchers("/acquisition/**").hasRole("ADMIN")
                //.and().exceptionHandling().accessDeniedPage("/Access_Denied");
                //all the path need authentication
                .anyRequest().authenticated()
                .and() //Login Form configuration for all others
            .formLogin()
                .loginPage("/login")
                //important because otherwise it goes in a loop because login page require authentication and authentication require login page
                    .permitAll()
            .and()
            .logout()
                .logoutSuccessUrl("/login?logout")
                .permitAll();
        }
    }
}

我的LDAP开发环境在Apache目录工作室中创建

解决方法

Spring Security已经支持LDAP开箱即用.它实际上有一个 whole chapter这个.

要使用和配置LDAP,请添加spring-security-ldap依赖项,接下来使用AuthenticationManagerBuilder.ldapAuthentication进行配置. LdapAuthenticationProviderConfigurer允许您设置所需的东西.

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    auth.ldapAuthentication()
      .contextSource()
        .url(...)
        .port(...)
        .managerDn(...)
        .managerPassword(...)
      .and()
        .passwordEncoder(passwordEncoder())
        .userSearchBase(...)        
        .ldapAuthoritiesPopulator(new UserServiceLdapAuthoritiesPopulater(this.userService));      
}

这样的东西(它应该给你至少一个关于什么/如何配置事情的想法)有更多的选择,但检查javadocs.如果您不能使用UserService来检索角色(因为只有角色在数据库中),那么可以实现自己的LdapAuthoritiesPopulator.
