Spring framerwork入门实例（4.2.4）

Spring framerwork入门实例（4.2.4）
1、下载Spring framerwork
下载地址：http://maven.springframework.org/release/org/springframework/spring/
2、解压并在spring-framework-4.2.4.RELEASE\libs 找到如下JAR包：
spring-beans-4.2.4.RELEASE.jar
spring-context-4.2.4.RELEASE.jar
spring-core-4.2.4.RELEASE.jar
spring-expression-4.2.4.RELEASE.jar

commons-logging-1.1.3.jar//此jar文件是apache提供的日志包 http://pan.baidu.com/s/1sk42Dkh

3、创建java项目把以上jar文件复制到项目的src目录下
4、在src目录下创建bean.xml文件(也可以是applicationContext.xml)

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4 xsi:schemaLocation="http://www.springframework.org/schema/beans 
 5 http://www.springframework.org/schema/beans/spring-beans-4.2.xsd">
 6 
 7 <bean id="user" class="com.entity.User">
 8 <!-- 依赖构造方法注入 -->
 9 <!-- 
10 <constructor-arg name="id" value="100" />
11 <constructor-arg name="name" value="张三丰" />
12 -->
13 <!-- 依赖setter注入 -->
14 <property name="id" value="20160126"></property>
15 <property name="name" value="Xsum"></property>
16 </bean>
17 </beans>

5、建立com.entity.User.java类

 1 package com.entity;
 2 
 3 public class User {
 4 private int id;
 5 private String name;
 6 public int getId() {
 7 return id;
 8 }
 9 public void setId(int id) {
10 this.id = id;
11 }
12 public String getName() {
13 return name;
14 }
15 public void setName(String name) {
16 this.name = name;
17 }
18 //依赖构造方法注入需添加构造方法
19 /*public User(int id, String name) {
20 super();
21 this.id = id;
22 this.name = name;
23 }
24 public User() {
25 }*/
26 }

6、建立com.test.Test.java类

 1 package com.test;
 2 
 3 import org.springframework.context.ApplicationContext;
 4 import org.springframework.context.support.ClassPathXmlApplicationContext;
 5 
 6 import com.entity.User;
 7 
 8 public class Demo {
 9 public static void main(String[] args) {
10 ApplicationContext ctx = new ClassPathXmlApplicationContext("bean.xml");
11 User user = (User)ctx.getBean("user");
12 System.out.println("id="+user.getId()+"\t"+"name="+user.getName());
13 }
14 
15 }

运行结果：
id=100 name=Xsum
