使用spring安全自定义过滤器时的java无限循环

我不知道为什么我的自定义过滤器只为无效凭证输入无限循环。下面是代码
过滤器：

package x.adldapdemo;

import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.web.filter.OncePerRequestFilter;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class LdapFilter extends OncePerRequestFilter {
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        String authorizationHeader = request.getHeader("Authorization");

        String token = authorizationHeader.substring("ldap ".length());

        int index = token.indexOf(":");

        if (index == -1) {

            throw new IllegalStateException("invalid authorization token");
        }

        String user = token.substring(0, index);
        String password = token.substring(index + 1, token.length());

        UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(user,password);

        SecurityContextHolder.getContext().setAuthentication(authenticationToken);

        filterChain.doFilter(request, response);
    }
}

供应商：

package x.adldapdemo;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.config.annotation.authentication.configurers.ldap.LdapAuthenticationProviderConfigurer;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.ldap.DefaultSpringSecurityContextSource;
import org.springframework.security.ldap.authentication.LdapAuthenticationProvider;
import org.springframework.stereotype.Component;

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

@Component
public class LdapProvider implements AuthenticationProvider{

    @Value("${ldap.urls}")
    private String ldapUrls;

    @Value("${ldap.base.dn}")
    private String ldapBaseDn;

    @Value("${ldap.username}")
    private String ldapSecurityPrincipal;

    @Value("${ldap.password}")
    private String ldapPrincipalPassword;

    @Value("${ldap.user.dn.pattern}")
    private String ldapUserDnPattern;

    @Value("${ldap.enabled}")
    private String ldapEnabled;
    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {

        DefaultSpringSecurityContextSource contextSource = new DefaultSpringSecurityContextSource(ldapUrls);
        contextSource.setUserDn(ldapSecurityPrincipal);
        contextSource.setPassword(ldapPrincipalPassword);
        contextSource.setBase(ldapBaseDn);
        contextSource.afterPropertiesSet();

        LdapAuthenticationProviderConfigurer ldapAuthenticationProviderConfigurer =
                new LdapAuthenticationProviderConfigurer().
                        userDnPatterns(ldapUserDnPattern);

        ldapAuthenticationProviderConfigurer.contextSource(contextSource);
        Method method = null;
        Object r = null;
        try {
            method = ldapAuthenticationProviderConfigurer.getClass().getDeclaredMethod("build");
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }
        method.setAccessible(true);
        try {
           r = method.invoke(ldapAuthenticationProviderConfigurer);
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }
        LdapAuthenticationProvider provider = (LdapAuthenticationProvider)r;
        Authentication authentication1 = provider.authenticate(authentication);
        return new UsernamePasswordAuthenticationToken(authentication1.getPrincipal(), authentication1.getCredentials());
    }

    @Override
    public boolean supports(Class<?> aClass) {
        return UsernamePasswordAuthenticationToken.class.isAssignableFrom(aClass);
    }
}

配置：

/**

package x.config;

import x.LdapFilter;
import x.LdapProvider;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;

import org.springframework.security.ldap.authentication.LdapAuthenticationProvider;
import org.springframework.security.web.authentication.www.BasicAuthenticationFilter;

/**

@EnableWebSecurity
@Configuration
public class SecurityConfig  extends WebSecurityConfigurerAdapter   {

    @Autowired
    private LdapProvider ldapProvider;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .addFilterBefore(new LdapFilter(), BasicAuthenticationFilter.class)
            .authorizeRequests()
                .antMatchers("/login**").permitAll()
                .antMatchers("/profile/**").fullyAuthenticated()
                .antMatchers("/").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .failureUrl("/login?error")
                .permitAll()
                .and()
            .logout()
                .invalidateHttpSession(true)
                .deleteCookies("JSESSIONID")
                .permitAll();
}

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

        auth.eraseCredentials(false).authenticationProvider(ldapProvider);

    }

}

我不知道为什么它只是在无效时才引起无限循环。是不是因为我授权了认证机制？
我关注了一些帖子，但无法确定原因。
我的假设是，当我没有任何提供者时，它也会表现相同。
添加stacktrace如下

这个堆栈跟踪多次出现，因为它多次通过相同的自定义过滤器。
