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

标签： struts2 struts2-junit-plugin

首先，抱歉，如果我没有足够清楚地解释它，我会尽力而为。最近，我从C / C＃切换到Java，但我有点不知所措。

我正在开发一个使用Struts2 + Hibernate的项目（我没有使用Spring）；当时的想法是使用struts2-JUnit插件来测试操作。

我没有成功地遵循strut2-junit-plugin教程，并且经过大量研究并尝试了所有可能的解决方案，这些解决方案我找不到合适的解决方案。

“问题”（因为我不太确定这是否是问题...），我遇到的问题是在设置过程中尝试运行StrutsTestCase时：

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)

此后，即使我得到了错误，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，调用时似乎找不到操作

  

ActionProxy代理= getActionProxy（“ / UpdatePassword.action”）;

在getActionProxy中抛出异常：

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，并且以下调用引发异常：

  

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

我放弃之前有什么主意吗？

谢谢！

万一其他人遇到同样的问题

您可以通过从配置struts2-cdi-plugin中排除

来解决此问题。
