java - 资源中点的 Spring Controller 请求映射问题

Question

我正在使用 spring 3.2.2 jar 并且有一个带有映射“/validate”的 Controller 。如果我在浏览器 url 中调用“/validate.123”，将执行此映射方法，这是不应该的。是不是我的代码有问题还是spring问题？

@Controller
@SessionAttributes
public class ValidationController {

    @RequestMapping(value = "/validate", method = { RequestMethod.POST,
            RequestMethod.GET })
    public ModelAndView validatCheck(@ModelAttribute("po") PO po){
    }

正如您在部署描述符 (web.xml) 中看到的那样，您已经编写了类似这样的内容

    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

哪个显示您的调度程序 servlet 将响应哪个 URL 模式

在这里<url-pattern>/</url-pattern>传达 dispatcher-servlet 将响应任何 URL 模式，如果你想限制 dispatcher-servlet 响应特定的 URL，你可以定义 Url 模式，如下所示

        <servlet-mapping>
            <servlet-name>mvc-dispatcher</servlet-name>
            <url-pattern>*.htm</url-pattern>
            <url-pattern>*.html</url-pattern>
        </servlet-mapping>
