首先确定学习内容：

1）spring依赖注入框架学习

2）spring mvc框架学习

第一天首先学习spring IOC

一、环境搭建

jdk使用1.6以上

服务使用tomcat7

开发工具使用eclipse

引入jar包，下面是基本IOC必须引入的包

commons-logging

org.springframework.asm

org.springframework.beans

org.springframework.context.support

org.springframework.context

org.springframework.core

org.springframework.expression

然后配置applicationContext.xml放到src目录下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
         http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsd
   http://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsd
   http://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-3.0.xsd
   http://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-3.0.xsd">

<bean id="user" class="com.zyd.spring.User">
  <property name="userName" value="测试zyd">
  </property>
  <property name="age" value="27">
  </property>
  <property name="gender" value="1">
  </property>
</bean>
</beans>

User类如下：

package com.zyd.spring;

public class User {
private String userName;

private Integer age;

private Integer gender;

public String getUserName() {
return userName;
}

public void setUserName(String userName) {
this.userName = userName;
}

public Integer getAge() {
return age;
}

public void setAge(Integer age) {
this.age = age;
}

public Integer getGender() {
return gender;
}

public void setGender(Integer gender) {
this.gender = gender;
}

}

Test中main方法如下：

public static void main(String[] args) {
  ApplicationContext applicationContext = new ClassPathXmlApplicationContext(
    "applicationContext.xml");
  User user = (User) applicationContext.getBean("user");
  System.out.println(user.getUserName());
}

打印结果为：测试zyd
