Question

我没有配置Spring的经验，而且我很难这样做。我正在尝试做的是使用注释成功地将URL映射到Controller。此外，我想访问HttpRequest和HttpResponse。这是因为我想使用Jackson直接在字节流中编写和解析json。现在我知道Spring有使用Jackson内置的JSON视图，但我想先得到一个不错的立足点，因为现在我似乎无法正确配置映射。

的web.xml

<display-name>Kerris 2</display-name>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/spring/*-config.xml
    </param-value>
</context-param>

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>
  <filter-name>springSecurityFilterChain</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

应用-confix.xml

<context:annotation-config />
<context:component-scan base-package="servlet" />

<bean
    class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
<bean
    class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

DayController

package servlet;

@Controller
@RequestMapping("/days/*")
public class DayController {

    private DayDAO dayDao;

    @RequestMapping(method = RequestMethod.GET)
    public @ResponseBody void test(HttpResponse response){
         System.out.println("Days GET");
    }

    @RequestMapping(method = RequestMethod.POST)
    public @ResponseBody void test2(HttpRequest request, HttpResponse response){
        System.out.println("Days POST");
    }

    public void setDaydao(DayDAO dayDao) {
        this.dayDao = dayDao;
        System.out.println("Days Dao assigned");
    }

}

当我查看我的服务器日志时，我可以在其中看到以下行

INFO: Mapped URL path [/days/*] onto handler 'dayController'
INFO: Mapped URL path [/days/*.*] onto handler 'dayController'
INFO: Mapped URL path [/days/*/] onto handler 'dayController'

当我在 contextroot / 测试应用程序时，我看到了标准的Hello World！页。当我尝试 contextroot / days / 时，我得到了404.当我尝试 contextroot / days / test 时也是404.有人能指出我做错了吗？< / p>

发现我做错了什么。作为n00b，我没有意识到我必须专门定义一个DispatcherServlet，它将请求交给控制器。

当我尝试拨打{contextroot} / api / days /时，请求到达控制器。
