根据给出的信息,很难说出你所知道的和你还不知道的.因此,我建议您在java.net LdapTemplate:Java Made Simple中使用这个有用的教程,跳过与您无关的章节(从2006年开始,但仍然可以).本文中引用的Spring LDAP现在是版本1.3.1.
如果您现在不想使用Spring LDAP,可以使用以下传统代码:
Map<String, String> env = new HashMap<String, String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://localhost:389/dc=jayway,dc=se");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "uid="+ username +",ou=system"); // replace with user DN
env.put(Context.SECURITY_CREDENTIALS, password);
DirContext ctx;
try {
ctx = new InitialDirContext(env);
} catch (NamingException e) {
// handle
}
try {
SearchControls controls = new SearchControls();
controls.setSearchScope( SearchControls.SUBTREE_SCOPE);
ctx.search( "", "(objectclass=person)", controls);
// no need to process the results
} catch (NameNotFoundException e) {
// The base context was not found.
// Just clean up and exit.
} catch (NamingException e) {
// exception handling
} finally {
// close ctx or do Java 7 try-with-resources http://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html

使用Spring LDAP身份验证测试LDAP连接:
即使用authenticate()方法:
ldapTemplate.authenticate(query, password);

甚至更好,使用getContext()方法:
ldapTemplate.getContextSource().getContext(userDn, userPassword));

捕获org.springframework.ldap.CommunicationException以检查连接是否成功.
完整的代码段应如下所示:
// Create the spring LdapTemplates; i.e. connections to the source and target ldaps:
try {
// Note: I'm using the direct LdapTemplate initialization rather than with bean creation (Spring ldap supports both)
log.info("Connecting to LDAP " + sourceHost + ":" + sourcePort + "...");
LdapContextSource sourceLdapCtx = new LdapContextSource();
sourceLdapCtx.setUrl("ldap://" + sourceHost + ":" + sourcePort + "/");
sourceLdapCtx.setUserDn(sourceBindAccount);
sourceLdapCtx.setPassword(sourcePassword);
sourceLdapCtx.setDirObjectFactory(DefaultDirObjectFactory.class);
sourceLdapCtx.afterPropertiesSet();
sourceLdapTemplate = new LdapTemplate(sourceLdapCtx);
// Authenticate:
sourceLdapTemplate.getContextSource().getContext(sourceBindAccount, sourcePassword);
} catch (Exception e) {
throw new Exception("Failed to connect to LDAP - " + e.getMessage(), e);

注意:我使用的是spring LDAP 2.3.x版本:
<dependency>
<groupId>org.springframework.ldap</groupId>
<artifactId>spring-ldap-core</artifactId>
</dependency>
