Question

我正在尝试在网址

中传递country和name

http://localhost:8080/FirstSpringMVCProject/berlin/alex

但是在输入上述网址时我收到以下信息：

Jun 21, 2016 1:18:37 AM org.springframework.web.servlet.PageNotFound noHandlerFound
WARNING: No mapping found for HTTP request with URI [/FirstSpringMVCProject/berlin/alex]
in DispatcherServlet with name 'spring-dispatcher'

和错误404

如何在URL中传递多个变量？我只是在URL中使用了一个变量name来尝试它并且它有效。

Answer 1

您不需要在dispatcher-servlet.xml中编写这样的bean，因为您已经为它添加了注释。

<bean name="/welcome/{countryName}/{userName}" class="com.stack.HelloController" />

<bean name="/hi" class="com.stack.HelloController" />

没有它你的项目应该可以正常工作。在您的web.xml文件中，您需要添加

<load-on-startup>1</load-on-startup>

这允许你的servlet容器初始化spring。

Answer 2

检查您的网址：

http://localhost:8080/FirstSpringMVCProject/berlin/alex/

但是，您在请求映射中提到了 welcome ，该映射在受尊重的URL中缺失。
因此，没有请求图表可以解决您的网址。
添加欢迎到您的浏览器网址路径
那么你的网址将是

http://localhost:8080/FirstSpringMVCProject/welcome/berlin/alex

请求映射中的

或删除 welcome 。

然后请求映射将像这样

@RequestMapping（path =“/ {countryName} / {userName}”，method = RequestMethod.GET

将多个变量传递给控制器
