春天没有检测到我@pathvariable

Question

我有我的控制器的一个问题，它没有处理URL时，它应该是，这里是代码：

@RequestMapping(value = "seeRoom/{user}/{id}") 
public String getSeeMessage(@PathVariable("user") String user, @PathVariable("id") int id, Model model) { 
    System.out.println(id); 
    return "room"; 
} 

这里是网络。 XML：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" 
     version="3.1"> 
    <servlet> 
     <servlet-name>mif03</servlet-name> 
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 

    <servlet-mapping> 
     <servlet-name>myApp</servlet-name> 
     <url-pattern>/backoffice</url-pattern> 
    </servlet-mapping> 
    <servlet-mapping> 
     <servlet-name>mif03</servlet-name> 
     <url-pattern>/users</url-pattern> 
    </servlet-mapping> 
    <servlet-mapping> 
     <servlet-name>myApp</servlet-name> 
     <url-pattern>/seeRoom/*</url-pattern> 
    </servlet-mapping> 

    <context-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>/WEB-INF/myApp-servlet.xml</param-value> 
    </context-param> 
</web-app> 

这里是myApp.xml：

<beans xmlns="http://www.springframework.org/schema/beans" 
xmlns:context="http://www.springframework.org/schema/context" 
xmlns:mvc="http://www.springframework.org/schema/mvc"

     http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> 

<context:component-scan base-package="controller" /> 
<context:component-scan base-package="model" /> 
<bean id="viewResolver" 
    class="org.springframework.web.servlet.view.UrlBasedViewResolver"> 
    <property name="viewClass" 
     value="org.springframework.web.servlet.view.JstlView" /> 
    <property name="prefix" value="/" /> 
    <property name="suffix" value=".jsp" /> 
</bean> 

和我的日食给我这个当我尝试访问该页面：

WARNING: No mapping found for HTTP request with URI [/my-webapp/seeRoom/admin/0] in DispatcherServlet with name 'myApp' 

静态处理，做工精细，但它看起来像春天没有检测到我@PathVariable

我觉得你的映射不是正确配置。尝试定义servlet-mapping为dispatcherServlet这样的：

<servlet-mapping> 
    <servlet-name>dispatcherServlet</servlet-name> 
    <url-pattern>/seeRoom</url-pattern> 
</servlet-mapping> 

希望它能帮助！

另请参阅：https://stackoverflow.com/a/17946825/6372139作进一步解释。

还要确保jsp文件位于正确的位置。您的ViewResolver前缀配置为/，但您通常想要的内容与/WEB-INF/views/类似。

最后，你可以使用方便的InternalResourceViewResolver而不是它的基类UrlBasedViewResolver。请参阅：https://stackoverflow.com/a/17453197/6372139以获取有关此主题的更多信息。
