Spring MVC的3.1注释没有？ [英] Spring MVC 3.1 without annotations?

问题描述

我开始使用Spring 3.1的新项目，并已眼球深处关于如何使用注解@Controller的所有文件和论坛的意见。

I'm starting a new project with Spring 3.1, and have been eyeball deep in all the documentation and forum opinions about how to use the @Controller annotation.

我个人不喜欢使用注解MVC;我有很多preFER可用的webapp所有URL在一个地方，使用SimpleUrlHandlerMapping建立。

I personally dislike using annotations for MVC; I much prefer having all the URLs of a webapp available in one place, using SimpleUrlHandlerMapping.

另外，从使用Spring 2.x的多previous的工作，我很习惯了BaseCommandController层次结构。

Also, from much previous work using Spring 2.x, I'm very used to the BaseCommandController heirarchy.

我总是喜欢春天，因为它的授权没有被限制。现在我发现Spring MVC中迫使我把URL转换成Java源代码，这意味着（一）我控制器不能映射到多个URL，以及（b）发现什么URL是在web应用程序的使用，我必须扫描通过不同的Java源文件，我觉得这是不切实际的。

I've always loved Spring because it's empowering without being restricting. Now I find Spring MVC is forcing me to put URLs into the java source, meaning (a) I can't map a controller to several URLs, and (b) to discover what URLs are in use in a webapp, I have to scan through different java source files, which I find impractical.

什么是@Controller与SimpleUrlHandlerMapping建立相结合的推荐方式，好吗？

What is the recommended way of combining @Controller with SimpleUrlHandlerMapping, please ?

更新：

戴夫你好，你说你可以映射像这样多个URL（从petclini.web.ClinicController改变）？

Hi Dave, are you saying you can map multiple URLs like this (altered from petclini.web.ClinicController)?

@RequestMapping({"/vets", "/another"})
public ModelMap vetsHandler() {

如果这工作那么好。

我的问题仍然有效，但：
如果我不希望在我的Java源代码的网址，如何最好地使用@Controller类并将它们映射？

My question still stands though: If I don't want URLs in my java source, how best to map them with @Controller classes?

问候，

推荐答案

下面是一个简单的设置来支持注释和非注释的控制器。

Here is a simple set up to support annotation and non-annotated controllers.

调度servlet配置XML

Dispatcher servlet configuration xml

<mvc:annotation-driven/>
<bean id="testController" class="com.test.web.TestController"/>
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
  <property name="mappings">
      <value>
      /test=testController
      </value>
  </property>
  <property name="order" value="0"/>
</bean>

一个简单的URL映射到控制器

A simple URL mapped controller

public class TestController implements Controller {

    @Override
    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
        PrintWriter responseWriter = response.getWriter();
        responseWriter.write("test");
        responseWriter.flush();
        responseWriter.close();
        return null;
    }
}

The controller for mvc annotation-config
@Controller
@RequestMapping("/home")
public class HomeController {

    @RequestMapping(method = RequestMethod.GET)
    @ResponseBody
    public String dashboard(Model model, HttpServletRequest request) {
        return "home";
    }
}

如果你想使用自己的处理程序@Controller注解。你也许可以考虑ClassPathBeanDefinitionScanner和DefaultAnnotationHandlerMapping.determineUrlsForHandlerMethods。

If you want to use your own handlers for @Controller annotation. you can probably look into ClassPathBeanDefinitionScanner and DefaultAnnotationHandlerMapping.determineUrlsForHandlerMethods.
