请求映射 - Spring 4 - 不起作用

Question

我有一个非常简单的问题.在我的.jsp文件中,我有**/registration的链接,方法viewRegistration被执行,一切正常.如果我有**/registration/getTags的链接？找不到tagName = blahblah页面.我不知道为什么,因为我认为我的requestMapping注释看起来是正确的......我将非常感谢你的帮助!

控制器:

@Controller
@RequestMapping(value = "/registration")
public class HelloController {

    final static Logger logger = Logger.getLogger(HelloController.class);

    @RequestMapping(method = RequestMethod.GET)
    public String viewRegistration(Map<String, Object> model, HttpSession session) {
        ...
   }

@RequestMapping(value = "/getTags", method = RequestMethod.GET)
    public @ResponseBody
    List<Tag> getTags(@RequestParam String tagName) {

        ....

    }
}

    <bean id="messageSource"
        class="org.springframework.context.support.ResourceBundleMessageSource">
        <property name="basename" value="website" />
    </bean>


</beans>

编辑编辑:我甚至尝试过更简单:

@RequestMapping(value = "/getTags")
    @ResponseBody
    public List<Tag> getTags() {
        String tagName="";
        return simulateSearchResult(tagName);

    }

但仍然/ registration/getTags不起作用...,找不到页面.

Answer 1

的servletURL映射如下:

 <servlet-mapping>
    <servlet-name>xxx</servlet-name>
    <url-pattern>/registration/*</url-pattern>
  </servlet-mapping>

这意味着所有urls开头/registration/*的servlet东西都会被它所处理,它将由它来处理controller.因此,如果您使用控制器配置控制器,@RequestMapping(value="/otherURL") 它将提供以下服务Url:

http://localhost:xxxx/<appname>/registration/otherURL

在这种情况下,为了访问正确的方法,您应该:

• @RequestMapping("/registration)来自控制器,因为它已经映射到servlet级别,并调用:

  http://localhost:xxxx/<appname>/registration/getTags?tagName=blahblah会正常工作. 或者:

• 请拨打以下网址: http://localhost:xxxx/<appname>/registration/registration/getTags?tagName=blahblah
