在Spring 3.0.5及之前的版本中，可以创建一个基本控制器测试类，它从Spring Application Context中获取HandlerMapping对象，以通过URL直接访问和调用控制器的方法。我发现这种方法非常棒，因为除了测试控制器的方法之外，我还在我的单元/集成测试中测试路径变量等。
使用Spring 3.2.4，由于重构了Spring处理Url映射的方式，这种方法似乎不再可能。我看到Spring提供了一个新的MVC测试框架，但说实话，我认为它的设计过于冗长，看起来与框架的其余部分或我的应用程序代码完全不同。它也不能很好地与IntelliJ中的智能感知功能配合使用。说实话，我宁愿不使用它。
那么，是否有另一种方法来测试不使用新的Spring MVC测试框架的控制器URL，就像我之前做的那样？我有一个371控制器测试的现有项目，我真的想避免迁移所有东西以使用Spring MVC测试框架。
这是我用来测试使用Spring 3.0.5的控制器的handle()方法：
protected ModelAndView handle(HttpServletRequest request, HttpServletResponse response) throws Exception {
final HandlerMapping handlerMapping = applicationContext.getBean(HandlerMapping.class);
final HandlerExecutionChain handler = handlerMapping.getHandler(request);
assertNotNull("No handler found for request, check you request mapping", handler);
final Object controller = handler.getHandler();
final HandlerInterceptor[] interceptors = handlerMapping.getHandler(request).getInterceptors();
for (HandlerInterceptor interceptor : interceptors) {
final boolean carryOn = interceptor.preHandle(request, response, controller);
if (!carryOn) {
return null;
}
}
return handlerAdapter.handle(request, response, controller);
}
protected ModelAndView handle(String method, String path, String queryString) throws Exception {
request.setMethod(method);
request.setRequestURI(path);
if(queryString != null) {
String[] parameters = queryString.split("&");
for(String parameter : parameters) {
String[] pair = parameter.split("=");
if(pair.length == 2) {
request.setParameter(pair[0], pair[1]);
} else {
request.setParameter(pair[0], "");
}
}
}
return handle(request, response);
}
protected ModelAndView handle(String method, String path, String attribute, Object object) throws Exception {
MockHttpSession session = new MockHttpSession();
session.setAttribute(attribute, object);
request.setSession(session);
return handle(method, path, null);
}
protected ModelAndView handle(String method, String path) throws Exception {
return handle(method, path, null);
}
以下是一些测试代码，说明了我如何使用handle()方法：
@Test
public void show() throws Exception {
ModelAndView modelAndView = handle("GET", "/courseVersion/1/section/1");
Section section = (Section) modelAndView.getModel().get("section");
assertEquals(1, section.getId());
}
这是我的servlet应用程序上下文：

答案 0 :(得分：1)
基本上你的测试方法从一开始就存在缺陷。总有可能存在多于1个HandlerMapping和1个HandlerAdapter。你基本上做的是模仿DispatcherServlet。
您应该做的是查找所有HandlerMapping和HandlerAdapter并检查其中一个是否与该网址匹配（即返回HandlerExecutionChain）并选择相应的HandlerAdapter （调用supports方法）。你在做什么基本上是DispatcherServlet正在做的事情。
