java静态调用_java 调用静态方法

我定义这样的一个类：

public class TestData extends HibikiRestTest {

private static final String binderKey = "InRepositoryBinder";

private static final String binderName = "TestBinder";

private static final String cabinetName = "TestCabinet";

public static void initBinderTestData() throws Exception {

logger.debug("Create Binder Data for Binder Rest Test Purpose. START");

Account account = APIAccountManager.getAccount(Integer.parseInt(loginId));

SmartdbAPI api = SmartdbAPI.getStandaloneSmartdbAPI();

api.setSessionUser(account);

BinderManager bman = api.getBinderManager();

APICabinet cabinet = bman.newCabinet();

cabinet.setName(cabinetName);

cabinet.setOwner(account);

bman.saveCabinet(cabinet);

.....

想在BindersResourceTest1这个类调用TestData这个类里的initBinderTestData()方法

public class BindersResourceTest1 extends HibikiRestTest{

TestData.initBinderTestData();

.....

但是报错：

我想知道这是为什么？
