1、加入?jar
2、web.xml配置：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>
<servlet-name>action</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>action</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
3、springMVC.xml配置
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
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-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">
<!-- 注解驱动 -->
<mvc:annotation-driven/>
<!-- 组件扫描 -->
<context:component-scan base-package="cn.itcast.springmvc.controller"></context:component-scan>
<!-- 配置内部资源视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
4、实体bean
package cn.itcast.springmvc.domain;
public class User {
private String name;
private String address;
private Integer age;
private String tel;
public String getName() {
return name;
}
public void setName(String name) {
System.out.println("正在通过setName方法注入name的值：" + name);
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getTel() {
return tel;
}
public void setTel(String tel) {
this.tel = tel;
}
@Override
public String toString() {
return "{name:" + name + ",address:" + address + ",age:" + age
+ ",tel:" + tel + "}";
}
}
5、编写HomeController,代码例如以下：
package cn.itcast.springmvc.controller;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import cn.itcast.springmvc.domain.User;
/**
* @brief IAccountDao.java 学习Spring注解方式
* @attention
* @author 涂作权
* @date 2014-5-18
* @note begin modify null
*/
@Controller //加入?注解
@RequestMapping(value = "/home") // 根路径，有些类似strut2的命名空间
public class HomeController {
/**
* 子路径，表示仅仅支持get提交
* @param req 能够通过传递HttpServletRequest的方式获得參数
* @param name 表示连接的地方有：XXX?name=
* @param u 假设url的？后面參数过多，要想获得參数，能够直接将这个參数写成User
* @param model :定义一个Map对象，能够通过这样的方式将之传递给jsp页面
*
* @attention url地址能够是：http://localhost:8081/SpringMVC_02/home/hello
* ?name=toto&address=haidian&age=24&tel=136XXX
* 获得的參数为：正在运行hello方法 name:toto User: {name:toto,address:haidian,age:24,tel:136XXX}
* @return
*/
@RequestMapping(value="/hello",method=RequestMethod.GET)
public String hello(HttpServletRequest req,
@RequestParam(value = "name")
String name, User u, Map<String, Object> model) {
//String name = req.getParameter("name");
System.out.println("正在运行hello方法 name:" + name);
System.out.println("User: " + u);
//req.setAttribute("msg", "hello " + name);
model.put("msg", "hello " + name);
return "hello";//逻辑名
}
/**
* \brief 定义方法hi
*
* @return
* @attention url的地方通过/home/hi的方式訪问要想訪问的地址
* @author 涂作权
* @date 2014-5-18
* @note begin modify by null
*/
@RequestMapping(value="/hi") //子路径
public String hi(){
System.out.println("正在运行hi方法");
return "hi"; //逻辑名
}
}
6、编写的hello.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head>
<title> ‘hello.jsp‘</title>
</head>
<body>
${requestScope.msg}
</body>
</html>
基于注解的Spring MVC
