搭建springmvc
1,下载jar包,我下的是:
spring-framework-3.1.0.RELEASE-with-docs.zip
spring-framework-3.0.5.RELEASE-dependencies.zip
引入dist目录下除了下面三个其余所有包:
org.springframework.web.struts-3.1.0.RELEASE.jar
org.springframework.spring-library-3.1.0.RELEASE.libd
org.springframework.web.portlet-3.1.0.RELEASE.jar
引入依赖包下:
com.springsource.org.apache.commons.logging-1.1.1.jar,
com.springsource.org.aopalliance-1.0.0.jar
spring框架配置:
1,web.xml配置:
<?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"> <context-param> <param-name>contextConfigLocation</param-name> <!-- 应用上下文配置文件 --> <param-value>/WEB-INF/spring-servlet.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置spring核心servlet --> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- url-pattern配置为/,不带文件后缀,会造成其它静态文件(js,css等)不能访问。如配为*.do,则不影响静态文件的访问 --> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
2,应用上下文配置:
spring-servlet.xml即配置用于开启基于注解的springMVC功能,照web.xml中设定,路径为WEB-INF下
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc" 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.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- 启动注解驱动的Spring MVC功能,注册请求url和注解POJO类方法的映射--> <mvc:annotation-driven /> <!-- 启动包扫描功能,以便注册带有@Controller、@Service、@repository、@Component等注解的类成为spring的bean --> <context:component-scan base-package="com.mvc.rest" /> <!-- 对模型视图名称的解析,在请求时模型视图名称添加前后缀 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/view/" p:suffix=".jsp" /> </beans>
Demo例子:
1、根据spring-servlet.xml配置的包路径(com.mvc.rest)新建Constroller
package com.mvc.rest; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @Controller public class RestConstroller { @RequestMapping(value = "/hello.act", method = RequestMethod.GET) public String registPost() { return "/hello"; } }
2、建jsp视图
视图路径在spring-servlet.xml配置(/WEB-INF/view/),据上述RestConstroller 类,我们在WEB-INF下建立view目录,在view下建立welcome.jsp
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'hello.jsp' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> This is my JSP page. hello<br> </body> </html>
