我想弄清楚Spring LDAP(不是 Spring安全事物)是如何工作的,通過設置最基本的工作程序,但似乎實際的認證中斷了。春季LDAP基本用法
這是錯誤我得到:
Exception in thread "main" java.lang.NullPointerException at org.springframework.ldap.core.support.AbstractContextSource.getReadOnlyContext(AbstractContextSource.java:125) at org.springframework.ldap.core.LdapTemplate.search(LdapTemplate.java:287) at org.springframework.ldap.core.LdapTemplate.search(LdapTemplate.java:237) at org.springframework.ldap.core.LdapTemplate.search(LdapTemplate.java:588) at org.springframework.ldap.core.LdapTemplate.search(LdapTemplate.java:546) at org.springframework.ldap.core.LdapTemplate.search(LdapTemplate.java:401) at org.springframework.ldap.core.LdapTemplate.search(LdapTemplate.java:421) at org.springframework.ldap.core.LdapTemplate.search(LdapTemplate.java:441)
是在這的投擲異常的方法執行的代碼是:
return getContext(authenticationSource.getPrincipal(),
authenticationSource.getCredentials());
所以好像我需要建立一個認證源在應用程序上下文中?我真的迷失了。
這裏是我的代碼:
package se.test.connector.ldap;
import java.util.List;
import javax.naming.NamingException;
import javax.naming.directory.Attributes;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.ldap.core.AttributesMapper;
import org.springframework.ldap.core.DistinguishedName;
import org.springframework.ldap.core.LdapTemplate;
import org.springframework.ldap.core.support.LdapContextSource;
import org.springframework.ldap.filter.EqualsFilter;
public class LdapTest {
public static void main(String[] args) {
LdapContextSource ctxSrc = new LdapContextSource();
ctxSrc.setUrl("ldap://<ldapUrl>:389");
ctxSrc.setBase("DC=bar,DC=test,DC=foo");
ctxSrc.setUserDn("<username>@bar.test.foo");
ctxSrc.setPassword("<password>");
LdapTemplate tmpl = new LdapTemplate(ctxSrc);
PersonDao dao = new PersonDao(tmpl);
dao.getAllPersonNames();
}
public static class PersonDao {
private LdapTemplate ldapTemplate;
public PersonDao(LdapTemplate ldapTemplate) {
this.ldapTemplate = ldapTemplate;
}
public void setLdapTemplate(LdapTemplate ldapTemplate) {
this.ldapTemplate = ldapTemplate;
}
public List getAllPersonNames() {
EqualsFilter filter = new EqualsFilter("objectclass", "person");
return ldapTemplate.search(DistinguishedName.EMPTY_PATH,
filter.encode(),
new AttributesMapper() {
public Object mapFromAttributes(Attributes attrs) throws NamingException {
return attrs.get("cn").get();
}
});
}
}
}
給予好評,因爲你的榜樣讓我有類似的問題,謝謝! :-) – ollo
