1、下载 spring 包，http://www.springsource.org/download
我下的是spring-framework-4.0.6.RELEASE
2、新建 web项目，在/WebRoot/lib 导入.jar包（/spring-framework-4.0.6.RELEASE/libs目录下）
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"> <!-- 应用上下文配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-servlet.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置servlet 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。 如配置为*.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、应用上下文配置文件，spring-servlet.xml（web中定义存放路径为：/WEB-INF/spring-servlet.xml）
<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="sendi.znwg.rest"></context:component-scan> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/view" p:suffix=".jsp"></bean> </beans>
3、Demo例子
根据spring-servlet配置的包路径（sendi.znwg.rest），新建RestController.java
@Controller public class RestController { public RestController(){ } @RequestMapping(value = "/login/{user}",method=RequestMethod.GET) public ModelAndView rest(HttpServletRequest request, HttpServletResponse response,@PathVariable("user")String user,ModelMap modelMap){ modelMap.put("loginUser", user); return new ModelAndView("/login/hello",modelMap); } @RequestMapping(value="/welcome",method = RequestMethod.GET) public String registPost(){ return "/welcome"; } }
可以自定义jsp（视图路径 /WEB-INF/view 下）
hello.jsp
<%@page import="java.util.Date"%> <%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>hello 页面</title> </head> <body> <h2> 你好：<%=request.getAttribute("loginUser") %>，现在的时间是<%=new Date() %> </h2> </body> </html>
tomcat部署后访问：
http://localhost:8080/spring-mvcDay2/login/gzsendi
