Spring LDAP 抛出 NPE

Question

我正在使用以下代码通过 spring LDAP 进行身份验证。

public static void main(String[] args) {
    String username = "kgam";
    String password = "password";

    LdapContextSource ctxSrc = new LdapContextSource();
    ctxSrc.setUrl(URL);
    ctxSrc.setBase(BASE);
    ctxSrc.setUserDn(USERDN);
    ctxSrc.setPassword(PASSWORD);
    LdapTemplate ldapTemplate = new LdapTemplate(ctxSrc);
    AndFilter filter = new AndFilter();
    ldapTemplate.setIgnorePartialResultException(true);
    filter.and(new EqualsFilter("objectClass", "person")).and(new EqualsFilter("sAMAccountName", username));
    System.out.println(ldapTemplate.authenticate(BASE, filter.toString(), password));
}

它使用以下堆栈跟踪抛出 NPE。

Exception in thread "main" java.lang.NullPointerException

    at org.springframework.ldap.core.LdapTemplate.search(LdapTemplate.java:286)

关于我哪里错了有什么想法吗？

如果您在 Spring 的帮助下完全配置 Spring LDAP，就像在您的示例中一样，您需要在完成配置后在 ContextSource 上调用 afterPropertiesSet .
