Spring LDAP，在Java中设置连接详细信息

Question

I want to set LDAP connection to list all users from AD. I successfully accomplished this with information stored in XML

<ldap:context-source
url="ldap://<url>"
base="dc=example,dc=local"
username="<user>@example.local"
password="<pass>" />

But how I can set this informations from Java, not in XML? Tried with:

LdapContextSource ctxSrc = new LdapContextSource();
    ctxSrc.setUrl("ldap://<url>");
    ctxSrc.setBase("dc=example,dc=local");
    ctxSrc.setUserDn("<user>@example.local");
    ctxSrc.setPassword("<pass>");
LdapTemplate tmpl = new LdapTemplate(ctxSrc);
setLdapTemplate(tmpl);

But when runing

List users = (List<User>) ldapTemplate.search(LdapUtils.emptyLdapName(), "(&(objectCategory=person)(objectClass=user))", new UserAttributesMapper());

I get NullPointerExeption . Runing that without setting up properties from java (ie reading from xml) everything works fine

Answer 1

please try this

LdapContextSource ctxSrc = new LdapContextSource();
    ctxSrc.setUrl("ldap://<url>");
    ctxSrc.setBase("dc=example,dc=local");
    ctxSrc.setUserDn("<user>@example.local");
    ctxSrc.setPassword("<pass>");

ctxSrc.afterPropertiesSet(); // this method should be called.

LdapTemplate tmpl = new LdapTemplate(ctxSrc);
setLdapTemplate(tmpl);
