问题描述
您好，我是 Spring 和 Java 的新手，我正在尝试按照本教程中的描述实现网关身份验证服务器 https://spring.io/guides/tutorials/spring-security-and-angular-js/
Hi I am new to Spring and Java, I am trying to implement a Gateway authentication server as described in this tutorial https://spring.io/guides/tutorials/spring-security-and-angular-js/
我让一切正常，然后尝试对我们公司的 Ldap 服务器实施身份验证.如果我使用有效的用户名和密码，它就可以工作.当我使用无效凭据时，应用程序错误.
I got everything working and then tried to implement the authentication against our company Ldap server. It works if I use a valid username and password. When I use invalid credentials the application errors.
我不在工作，所以我没有确切的错误，但它返回一个 ldap 错误 (com.sun.jndi.ldap.LdapCtx) 并且 Redis 正在尝试对其进行序列化.
I am not at work so I don't have the exact error, but it is returning an ldap error (com.sun.jndi.ldap.LdapCtx) and Redis is trying to serialize it.
我的配置中是否缺少某些内容.根据我的阅读，我认为我应该寻找一种方法来包装/扩展类并实现 Serializable，但我不确定使用 Spring Boot 执行此操作的侵入性最小的方法.
Is there something I am missing in my configuration. From what I have read I think I should be looking for a way to wrap/extend the class and implement Serializable, but I am unsure of the least invasive way to do this with Spring Boot.
非常感谢任何帮助.
谢谢，

以下是我认为安全配置的相关部分:
Here are what I think are the relevant parts of the Security configuration:
@Configuration
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.formLogin()
.defaultSuccessUrl("/")
.loginPage("/login")
.permitAll()
.and()
.logout()
.logoutSuccessUrl("/logout")
.permitAll();
http
.authorizeRequests()
.antMatchers("/login").permitAll()
.anyRequest().authenticated()
.and()
.csrf().csrfTokenRepository(csrfTokenRepository())
.and()
.addFilterAfter(csrfHeaderFilter(), CsrfFilter.class);
}
@Override
protected void configure(AuthenticationManagerBuilder authManagerBuilder) throws Exception {
authManagerBuilder
.authenticationProvider(activeDirectoryLdapAuthenticationProvider())
.userDetailsService(userDetailsService());
}
@Bean
public AuthenticationManager authenticationManager() {
return new ProviderManager(
Arrays.asList(activeDirectoryLdapAuthenticationProvider())
);
}
@Bean
public AuthenticationProvider activeDirectoryLdapAuthenticationProvider() {
ActiveDirectoryLdapAuthenticationProvider provider = new ActiveDirectoryLdapAuthenticationProvider(
"XXX.XXX", "ldaps://XXX.XXX:636");
provider.setConvertSubErrorCodesToExceptions(true);
provider.setUseAuthenticationRequestCredentials(true);
return provider;
}
private Filter csrfHeaderFilter() {
return new OncePerRequestFilter() {
@Override
protected void doFilterInternal(
HttpServletRequest request,
HttpServletResponse response,
FilterChain filterChain
) throws ServletException, IOException
{
CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class
.getName());
if (csrf != null) {
Cookie cookie = WebUtils.getCookie(request, "XSRF-TOKEN");
String token = csrf.getToken();
if (cookie == null || token != null
&& !token.equals(cookie.getValue())) {
cookie = new Cookie("XSRF-TOKEN", token);
cookie.setPath("/");
response.addCookie(cookie);
}
}
filterChain.doFilter(request, response);
}
};
}
private CsrfTokenRepository csrfTokenRepository() {
HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();
repository.setHeaderName("X-XSRF-TOKEN");
return repository;
}
}
这是使用无效凭据的错误的一部分:

推荐答案
我想出了解决这个问题的办法.我愿意接受任何改进答案的建议.
I figured out a solution to this problem. I am open to any suggestions to improve the answer.
解决方案不完整，因为我需要专门寻找com.sun.jndi.ldap.LdapCtx 类型当序列化失败时，我可以处理该特定情况并在所有其他情况下抛出 SerializationException.但我认为这个总体思路可能对任何被阻止的人有用.
The solution is not complete as I need to look specifically for the
com.sun.jndi.ldap.LdapCtx type when serialization fails so I can deal with that specific case and throw the SerializationException in all others. But I thought the general idea might be useful to anyone who is blocked on this.
现在，当使用无效凭据(例如错误的用户名或错误的密码)时，应用程序会返回登录页面而不是崩溃 :)
Now when invalid credentials are used (eg Bad Username or Incorrect Password) the application returns to the log in page rather than blowing up :)
我添加了一些 RedisConfiguration 来替换 Spring Session 正在使用的 RedisTemplate.
I added some RedisConfiguration to replace the RedisTemplate Spring Session is using.
import com.gateway.utils.LdapFailAwareRedisObjectSerializer;
@Configuration
public class RedisConfiguration {
@Primary
@Bean
public RedisTemplate<String,ExpiringSession> redisTemplate(RedisConnectionFactory connectionFactory) {
RedisTemplate<String, ExpiringSession> template = new RedisTemplate<String, ExpiringSession>();
template.setKeySerializer(new StringRedisSerializer());
template.setHashKeySerializer(new StringRedisSerializer());
template.setHashValueSerializer(new LdapFailAwareRedisObjectSerializer());
template.setConnectionFactory(connectionFactory);
return template;
}
}
这是我对 RedisSerializer 的实现(LdapFailAwareRedisObjectSerializer 来自 这里)
Here is my implementation of RedisSerializer<Object> (LdapFailAwareRedisObjectSerializer which is got from here)
public class LdapFailAwareRedisObjectSerializer implements RedisSerializer<Object> {
private Converter<Object, byte[]> serializer = new SerializingConverter();
private Converter<byte[], Object> deserializer = new DeserializingConverter();
static final byte[] EMPTY_ARRAY = new byte[0];
public Object deserialize(byte[] bytes) {
if (isEmpty(bytes)) {
return null;
}
try {
return deserializer.convert(bytes);
} catch (Exception ex) {
throw new SerializationException("Cannot deserialize", ex);
}
}
public byte[] serialize(Object object) {
if (object == null) {
return EMPTY_ARRAY;
}
try {
return serializer.convert(object);
} catch (Exception ex) {
return EMPTY_ARRAY;
//TODO add logic here to only return EMPTY_ARRAY for known conditions
// else throw the SerializationException
// throw new SerializationException("Cannot serialize", ex);
}
}
private boolean isEmpty(byte[] data) {
return (data == null || data.length == 0);
}
}
