I have a Web application. For LDAP I am using Apache Directive Studio.I want to get all the users and their roles in my application.
我有一个 Web 应用程序。对于 LDAP，我使用的是Apache Directive Studio。我想在我的应用程序中获取所有用户及其角色。
I am able to get particular information by using the following code.
我可以使用以下代码获取特定信息。
import java.util.Properties;
import javax.naming.Context;
import javax.naming.NamingException;
import javax.naming.directory.Attributes;
import javax.naming.directory.DirContext;
import javax.naming.directory.InitialDirContext;
public class DirectorySample {
public DirectorySample() {
}
public void doLookup() {
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
properties.put(Context.PROVIDER_URL, "ldap://localhost:10389");
try {
DirContext context = new InitialDirContext(properties);
Attributes attrs = context.getAttributes("dc=example,dc=com");
System.out.println("ALL Data: " + attrs.toString());
} catch (NamingException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
DirectorySample sample = new DirectorySample();
sample.doLookup();
}
}

You can use org.apache.directory.ldap.client.api.LdapConnection for easy search.
您可以使用 org.apache.directory.ldap.client.api.LdapConnection 进行轻松搜索。
Once you bind the connection, do search on the connection. Loop through the cursor to get the object you want. The first parameter should match your the DN of the users parent. Below example is just to give you an idea.
绑定连接后，请搜索连接。遍历光标以获得所需的对象。第一个参数应与用户父级的 DN 匹配。下面的例子只是给你一个想法。
EntryCursor cursor = connection.search( "ou=users, dc=example, dc=com", "(objectclass=*)", SearchScope.ONELEVEL, "*" );
while ( cursor.next() )
{
Entry entry = cursor.get();
//play with the entry
}
