Spring MVC - 简单的URL处理程序映射示例 Spring MVC - 控制器类名称处理程序映射示例 Spring MVC - 多动作控制器示例 以下示例说明如何使用Spring Web MVC框架使用简单URL处理程序映射。SimpleUrlHandlerMapping类有助于分别使用其控制器显式映射URL。 <beans> <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name = "prefix" value = "/WEB-INF/jsp/"/> <property name = "suffix" value = ".jsp"/> </bean> <bean class = "org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name = "mappings"> <props> <prop key = "/welcome.htm">welcomeController</prop> <prop key = "/helloWorld.htm">helloController</prop> </props> </property> </bean> <bean id = "helloController" class = "com.codingdict.HelloController" /> <bean id = "welcomeController" class = "com.codingdict.WelcomeController"/> </beans> 例如,使用上面的配置,如果是URI 请求/helloWorld.htm,DispatcherServlet会将请求转发给 HelloController 。 请求/welcome.htm,DispatcherServlet会将请求转发给 WelcomeController 。 首先,让我们使用一个可用的Eclipse IDE,并考虑使用Spring Web Framework开发基于动态表单的Web应用程序的以下步骤。 步 描述 1 在Spring MVC - Hello World章节中解释,在com.codingdict包下创建一个名为TestWeb的项目。 2 在com.codingdict包下创建Java类HelloController和WelcomeController。 3 在jsp子文件夹下创建视图文件hello.jsp和welcome.jsp。 4 最后一步是创建源文件和配置文件的内容并导出应用程序,如下所述。 HelloController.java package com.codingdict; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.AbstractController; public class HelloController extends AbstractController{ @Override protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView model = new ModelAndView("hello"); model.addObject("message", "Hello World!"); return model; } } WelcomeController.java package com.codingdict; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.AbstractController; public class WelcomeController extends AbstractController{ @Override protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView model = new ModelAndView("welcome"); model.addObject("message", "Welcome!"); return model; } } TestWeb-servlet.xml <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"> <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name = "prefix" value = "/WEB-INF/jsp/"/> <property name = "suffix" value = ".jsp"/> </bean> <bean class = "org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name = "mappings"> <props> <prop key = "/welcome.htm">welcomeController</prop> <prop key = "/helloWorld.htm">helloController</prop> </props> </property> </bean> <bean id = "helloController" class = "com.codingdict.HelloController" /> <bean id = "welcomeController" class = "com.codingdict.WelcomeController"/> </beans> hello.jsp <%@ page contentType = "text/html; charset = UTF-8" %> <html> <head> <title>Hello World</title> </head> <body> <h2>${message}</h2> </body> </html> welcome.jsp <%@ page contentType = "text/html; charset = UTF-8" %> <html> <head> <title>Welcome</title> </head> <body> <h2>${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 File 选项并将 TestWeb.war 文件保存在Tomcat的webapps文件夹中。 现在,启动Tomcat服务器并确保您可以使用标准浏览器从webapps文件夹访问其他网页。尝试一个URL - http:// localhost:8080 / TestWeb / helloWorld.htm ,如果Spring Web Application的一切正常,我们将看到以下屏幕。 尝试使用URL http:// localhost:8080 / TestWeb / welcome.htm ,如果Spring Web Application的一切正常,您应该会看到以下结果。 Spring MVC - 控制器类名称处理程序映射示例 Spring MVC - 多动作控制器示例
