Question

我正在使用PowerMock 1.5.1和Spring 3.1.1.RELEASE尝试模拟ResourceBundle。我试过了

    ResourceBundle resourceBundleMock = createMock(ResourceBundle.class);
    expect(resourceBundleMock.getString("error.invalid.login")).andReturn(errorMsg);

但是我得到了下面的例外

java.util.MissingResourceException: Can't find resource for bundle $java.util.ResourceBundle$$EnhancerByCGLIB$$8b09d230, key error.invalid.login

如何模拟对resourceBundle.getString方法的调用返回的内容，以便在我的Spring控制器中使用？我使用

在Spring中实例化一个ResourceBundle

 private static ResourceBundle resourceBundle = ResourceBundle.getBundle("UserMessages", Locale.ENGLISH);

K，想通了 - 没有正确地注射我的模拟。以下治愈疼痛

@RunWith(PowerMockRunner.class)
@PrepareForTest({ SecurityContextHolder.class })
public class LoginControllerTest 
{

    @Mock
    private ResourceBundle bundle;

    …

    @Test
    public final void testLoginError()
    {
        mockStatic(ResourceBundle.class);
        expect(ResourceBundle.getBundle("UserMessages", Locale.ENGLISH)).andReturn(bundle);

        final String errorMsg = "Invalid Login. Please reenter your username and password.";
        expect(bundle.getString("error.invalid.login")).andReturn(errorMsg);

        expect(loginService.getUrlProperties("localhost")).andReturn(url);
        replayAll();

如何使用Spring和PowerMock模拟ResourceBundle？
