spring框架jar包
1、下载spring源包
spring地址:http://www.springsource.org/download
我下的是spring-framework-3.1.0.RELEASE-with-docs.zip
下载依赖包:spring-framework-3.0.5.RELEASE-dependencies.zip
注意官网上3.0.3版本以后同版本依赖包不提供下载
2、导入所需jar包
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及com.springsource.org.aopalliance-1.0.0.jar
spring框架配置
1、web.xml配置
[html] view plain copy
- <?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
[html] view plain copy
- <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
[java] view plain copy
- package com.mvc.rest;
- import javax.servlet.http.HttpServletRequest;
- import javax.servlet.http.HttpServletResponse;
- import org.springframework.stereotype.Controller;
- import org.springframework.ui.ModelMap;
- import org.springframework.web.bind.annotation.PathVariable;
- import org.springframework.web.bind.annotation.RequestMapping;
- import org.springframework.web.bind.annotation.RequestMethod;
- import org.springframework.web.servlet.ModelAndView;
- @Controller
- public class RestConstroller {
- public RestConstroller() {}
- @RequestMapping(value = "/login/{user}", method = RequestMethod.GET)
- public ModelAndView myMethod(HttpServletRequest request,HttpServletResponse response,
- @PathVariable("user") String user, ModelMap modelMap) throws Exception {
- modelMap.put("loginUser", user);
- return new ModelAndView("/login/hello", modelMap);
- }
- @RequestMapping(value = "/welcome", method = RequestMethod.GET)
- public String registPost() {
- return "/welcome";
- }
- }
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及login/hello.jsp
welcome.jsp随意,hello.jsp代码如下:
[html] view plain copy
- <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
- <%
- 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">
- </head>
- <body>
- 你好:<%=request.getAttribute("loginUser") %>,现在时间是<%= new Date() %>
- </body>
- </html>
