无法使用 Struts2-Junit-Plugin 执行任何 StrutsTestCase，操作方法为空
Unable to execute any StrutsTestCase using Struts2-Junit-Plugin, action method is null
首先很抱歉，如果我解释得不够清楚，我会尽力而为。最近从C/C#换成了Java，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）；这个想法是使用 struts2-JUnit-plugin 来测试操作。
我遵循了 strut2-junit-plugin 教程但没有成功，经过大量研究并尝试了所有可能的解决方案后，我找不到好的解决方案。
"issues"（因为我不太确定这是否是一个问题...）我遇到的是，当我尝试 运行 一个 StrutsTestCase 时，在设置过程中：
super.setUp();
initServletMockObjects();
setupBeforeInitDispatcher();
dispatcher = initDispatcher(dispatcherInitParams);
setupAfterInitDispatcher(dispatcher);
当调用 dispatcher = initDispatcher(dispatcherInitParams) 时，dispatcherInitParams 为 null 并抛出以下堆栈跟踪：
ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...

这之后，即使报错了，我也可以继续测试，比如下面的测试：
@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好像没有找到action:
ActionProxy proxy = getActionProxy("/UpdatePassword.action");
它在 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;
}
此时字符串方法为空，下面的调用抛出异常：
ActionProxy proxy =
config.getContainer().getInstance(ActionProxyFactory.class).createActionProxy(
namespace, name, method, new HashMap(), true, false);
在我放弃之前有什么想法吗？
谢谢！
