Spring MVC系列：（7）SpringMVC快速入门（注解版本）
1、引入jar包
| spring-core | commons-logging-1.2.jar spring-beans-3.2.5.RELEASE.jar spring-context-3.2.5.RELEASE.jar spring-core-3.2.5.RELEASE.jar spring-expression-3.2.5.RELEASE.jar |
| spring-web | spring-web-3.2.5.RELEASE.jar |
| spring-webmvc | spring-webmvc-3.2.5.RELEASE.jar |
2、配置
web.xml
<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>springmvc02</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 注册SpringMVC核心控制器 --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>*.action</url-pattern> </servlet-mapping> <!-- 注册Spring的编码过滤器，位于spring-web的jar包中 --> <filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
springmvc.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- <import resource="com/rk/config/spring-test.xml"/> --> <!-- Action控制器 --> <context:component-scan base-package="com.rk.action"></context:component-scan> <!-- 基于注解的映射器(可选) --> <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> <!-- 基于注解的适配器(可选) --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/> <!-- 视图解析器(可选) --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"/> </beans>
3、创建HelloWorldAction控制器
HelloWorldAction.java
package com.rk.action;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloWorldAction {
@RequestMapping(value="http://www.mamicode.com/test")
public String test(Model model) throws Exception{
System.out.println("HelloWorldAction.test()");
model.addAttribute("message", "这是我的第二个SpringMVC应用程序！");
return "/index.jsp";
}
}4、JSP页面
修改WebRoot/下的index.jsp页面
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Index Page</title>
</head>
<body>
This is my JSP page. <br>
${message }
</body>
</html>5、部署访问
访问地址：
http://127.0.0.1:8080/springmvc02/test.action
