InternalResourceViewResolver 用于将提供的URI解析为实际的URI.以下示例显示如何使用Spring Web MVC框架使用InternalResourceViewResolver. InternalResourceViewResolver允许将网页映射到请求.
package com.it1352; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.ui.ModelMap; @Controller @RequestMapping("/hello") public class HelloController{ @RequestMapping(method = RequestMethod.GET) public String printHello(ModelMap model) { model.addAttribute("message", "Hello Spring MVC Framework!"); return "hello"; } }
<bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name = "prefix" value = "/WEB-INF/jsp/"/> <property name = "suffix" value = ".jsp"/> </bean>
例如,使用上面的配置,如果URI
/hello,DispatcherServlet会将请求转发到前缀+ viewname + suffix =/WEB-INF/jsp/hello.jsp.
首先,让我们使用一个可用的Eclipse IDE,然后考虑以下步骤,使用Spring Web Framework开发基于动态表单的Web应用程序.
Step | 描述 |
---|---|
1 | 在包com下创建一个名为TestWeb的项目. it1352在Spring MVC中解释 - Hello World Example章节. |
2 | 在com.it1352包下创建一个Java类HelloController. |
3 | 在jsp子文件夹下创建一个视图文件hello.jsp. |
4 | 最后一步是创建源文件和配置文件的内容并将应用程序导出为解释如下. |
package com.it1352; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.ui.ModelMap; @Controller @RequestMapping("/hello") public class HelloController{ @RequestMapping(method = RequestMethod.GET) public String printHello(ModelMap model) { model.addAttribute("message", "Hello Spring MVC Framework!"); return "hello"; } }
<beans xmlns = "http://www.springframework.org/schema/beans" xmlns:context = "http://www.springframework.org/schema/context" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation = " 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"> <context:component-scan base-package = "com.IT屋" /> <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name = "prefix" value = "/WEB-INF/jsp/" /> <property name = "suffix" value = ".jsp" /> </bean> </beans>
<%@ page contentType = "text/html; charset = UTF-8" %> <html> <head> <title>Hello World</title> </head> <body> <h2>${message}</h2> </body> </html>
完成创建源文件和配置文件后,导出应用程序.右键单击您的应用程序,使用 Export → WAR文件选项并将 TestWeb.war 文件保存在Tomcat的webapps文件夹中.
现在,启动Tomcat服务器并确保能够使用标准浏览器从webapps文件夹访问其他网页.尝试访问URL - http://localhost:8080/TestWeb/hello 如果Spring Web Application的一切正常,我们将看到以下屏幕.
