这是我的代码:
public class TestConnection {
public static void main(String[] args) {
String password = "s3cret";
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=userdev,dc=local");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
//env.put(Context.SECURITY_PRINCIPAL, "uid="+ username +"cn=users"); // replace with user DN
env.put(Context.SECURITY_PRINCIPAL, "cn=dcmanager,cn=users,dc=userdev,dc=local"); // replace with user DN
env.put(Context.SECURITY_CREDENTIALS, password);
DirContext ctx = null;
try {
ctx = new InitialDirContext();
} 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) {
e.printStackTrace();
System.out.println("catch 1");
// The base context was not found.
// Just clean up and exit.
} catch (NamingException e) {
System.out.println("catch 2");
e.printStackTrace();
// exception handling
} finally {
// close ctx or do Java 7 try-with-resources http://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html
}
}
}

我收到此错误(第2次捕获): javax.naming.NoInitialContextException:需要在环境或系统属性中,或作为applet参数或在应用程序资源文件中指定类名称:java.naming.factory.initial
我已经寻找了很多解决方案,但是我没有得到错误。问题出在哪里?也许是上下文,但是我认为代码是完全正确的。
