您可以使用Admin REST API。相关API的详细描述可以在这里获得。另外，您还可以使用JAVA包装器API。请找到以下几个例子。

示例1，REST：

获取访问令牌：

curl \
  -d "client_id=admin-cli" \
  -d "username=admin" \
  -d "password=secret" \
  -d "grant_type=password" \
  "http://localhost:8080/auth/realms/master/protocol/openid-connect/token"

curl \
  -H "Authorization: bearer eyJhbGciOiJSUzI...." \
  "http://localhost:8080/auth/admin/realms/master/users"

[
     {
        "id":"349f67de-36e6-4552-ac54-e52085109616",
        "username":"admin",
        "enabled":true,
        ...
     },
     {
        "id":"08afb701-fae5-40b4-8895-e387ba1902fb",
        "username":"lbalev",
        "enabled":true,
        ....
     }
  ]

curl \
  -H "Authorization: bearer eyJhbGciOiJSU...." \
  "http://localhost:8080/auth/admin/realms/master/users/349f67de-36e6-4552-ac54-e52085109616"

public class TestUserAccess {

  private static final String SERVER_URL = "http://localhost:8080/auth";
  private static final String REALM = "master";
  private static final String USERNAME = "admin";
  private static final String PASSWORD = "secret";
  private static final String CLIENT_ID = "admin-cli";

  public static void main(String[] args) {

    Keycloak keycloak = KeycloakBuilder
        .builder()
        .serverUrl(SERVER_URL)
        .realm(REALM)
        .username(USERNAME)
        .password(PASSWORD)
        .clientId(CLIENT_ID)
        .resteasyClient(new ResteasyClientBuilder().connectionPoolSize(10).build())
        .build();

    UsersResource usersResource = keycloak.realm(REALM).users();
    UserResource userResource = usersResource.get("08afb701-fae5-40b4-8895-e387ba1902fb");
    System.out.println(userResource.toRepresentation().getEmail());
  }
}
