无法使用Struts2-Junit-Plugin执行任何StrutsTestCase，操作方法为空。

Question

首先，对不起，如果我解释得不够清楚，我会尽力做到最好。最近，我从C/C#转向了Java，我有点不知所措。

我正在开发一个使用Struts2+Hibernate的项目(我不使用Spring)；我的想法是使用struts2-JUnit插件来测试这些操作。

我遵循了strut2-jun-plugin教程，但没有成功，经过大量的研究和尝试，所有可能的解决方案张贴到任何地方，我都找不到好的解决方案。

“问题”(因为我不确定这是否是个问题.)当我尝试运行StrutsTestCase时，在setUp期间，我就是这样做的：

super.setUp();
initServletMockObjects();
setupBeforeInitDispatcher();
dispatcher = initDispatcher(dispatcherInitParams);
setupAfterInitDispatcher(dispatcher);

调用dispatcher = initDispatcher( dispatcherInitParams )时，dispatcherInitParams为null，并引发以下堆栈跟踪：

    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192)

在这之后，即使我得到了错误，我也可以继续测试，例如，以下测试：

@Test
public void testGetActionProxy() throws Exception {

    //set parameters before calling getActionProxy
    PasswordUpdate pu = new PasswordUpdate();
    pu.setCurrentPassword("current");
    pu.setNewPassword("new");
    pu.setNewPasswordConfirm("new");
    request.setParameter("passwordUpdate.currentPassword", pu.getCurrentPassword());
    request.setParameter("passwordUpdate.newPassword", pu.getNewPassword());
    request.setParameter("passwordUpdate.newPasswordConfirm", pu.getNewPasswordConfirm());

    ActionProxy proxy = getActionProxy("/UpdatePassword.action");
    assertNotNull(proxy);

    PasswordAction action = (PasswordAction) proxy.getAction();
    assertNotNull(action);

    String result = proxy.execute();
    assertEquals(Action.SUCCESS, result);
    assertNotNull(action.getPasswordUpdate());
    assertEquals("current", action.getPasswordUpdate().getCurrentPassword());
    assertEquals("new", action.getPasswordUpdate().getNewPassword());
    assertEquals("new", action.getPasswordUpdate().getNewPasswordConfirm());

}

第二个问题是，当调用时，它似乎找不到操作：

ActionProxy proxy = getActionProxy("/UpdatePassword.action")；

它在getActionProxy中抛出一个异常：

protected ActionProxy getActionProxy(String uri) {
        request.setRequestURI(uri);
        ActionMapping mapping = getActionMapping(request);
        String namespace = mapping.getNamespace();
        String name = mapping.getName();
        String method = mapping.getMethod();

        Configuration config = configurationManager.getConfiguration();
        ActionProxy proxy = config.getContainer().getInstance(ActionProxyFactory.class).createActionProxy(
                namespace, name, method, new HashMap<String, Object>(), true, false);

        initActionContext(proxy.getInvocation().getInvocationContext());

        // this is normally done in onSetUp(), but we are using Struts internal
        // objects (proxy and action invocation)
        // so we have to hack around so it works
        ServletActionContext.setServletContext(servletContext);
        ServletActionContext.setRequest(request);
        ServletActionContext.setResponse(response);

        return proxy;
    }

此时，String方法为null，下面的调用将引发异常：

config.getContainer().getInstance(ActionProxyFactory.class).createActionProxy( ActionProxy代理=ActionProxy名称空间、名称、方法、新HashMap()、true、false)；

在我放弃之前知道吗？

谢谢!

如果其他人在这篇文章中出现了同样的问题

您可以通过从配置支柱中排除2-cdi-plugin来解决这个问题。
