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：
