如何解决简单的Servlet映射
| 我正在尝试将Spring实施到一个小型应用程序上。 我得到以下信息:WARNING: No mapping found for HTTP request with URI [/audiClave/] in DispatcherServlet with name \'appServlet\'
这是我的web.xml文件:
<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<web-app xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"
xmlns=\"http://java.sun.com/xml/ns/javaee\"
xmlns:web=\"http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd\"
xsi:schemaLocation=\"http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd\"
id=\"WebApp_ID\"
version=\"3.0\">
<display-name>audiClave</display-name>
<!-- Processes application requests -->
<servlet>
<servlet-name>appServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet- class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
这是servlet-context.xml:
<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<beans xmlns=\"http://www.springframework.org/schema/beans\"
xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"
xmlns:mvc=\"http://www.springframework.org/schema/mvc\"
xmlns:context=\"http://www.springframework.org/schema/context\"
xsi:schemaLocation=\"
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd\">
<!-- DispatcherServlet Context: defines this servlet\'s request-processing infrastructure -->
<!-- Scans within the base package of the application for @Components to configure as beans -->
<!-- @Controller,@Service,@Configuration,etc. -->
<context:component-scan base-package=\"com.audiClave.Service\" />
<!-- Enables the Spring MVC @Controller programming model -->
<mvc:annotation-driven />
</beans>
控制器是:
package com.audiClave.Service;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* Handles requests for the application home page.
*/
@Controller
public class HomeController {
@RequestMapping(value = \"/\")
public String home() {
System.out.println(\"HomeController: Passing through...\");
return \"WEB-INF/views/home.jsp\";
}
}
http:// localhost:8080 / audiClave /返回:
HTTP Status 404
The requested resource () is not available.
我正在使用tomcat 7.0.12和spring 3.0.5在eclipse下运行。内容似乎已正确部署到E:\\ development \\ java.metadata.plugins \\ org.eclipse.wst.server.core \\ tmp0 \\ wtpwebapps \\ audiClave
当我将映射更改为/ *时,它能够找到控制器,但是home.jsp无法正常工作,因为通配符也与之匹配
当我再次从映射中删除/ *时,已解决。
谢谢
解决方法
只做
return \"home\"
(而不是到jsp的整个路径)。应将View处理程序配置为在该文件夹中以该扩展名查找视图。
,问题应该是这样的:在[filename] -servlet.xml文件中,请输入以下行:
< mvc:resources location=\"/index.html\" mapping=\"/index.html\" />
