Oops! Spring Quick Start

Oops! Spring Quick Start

本文讲解一个不规范的spring quick start.

1. 下载spring的插件包，什么版本之类的不用管了。反正能用。
spring.jar  http://www.boxcn.net/shared/yg306zac1h
common-logging.jar  http://www.boxcn.net/shared/ix93ziqljv

2. 进入eclipse，File - New - Java Project.
projectname = spring001 ===> Next
在新建导向的第二页，是Java Settings, 选择Libraries -> Add External JARS -> 添加上面2个jar
finish

3. 进入Package Explorer, 在src下新建一个class.
Package = com.java114.spring.test
Name = HelloWordSpring
再复选框：public static void main(String[] args) 钩上

4. 在HelloWordSpring.java 输入以下的代码

package  com.java114.spring.test;

import  org.springframework.beans.factory.BeanFactory;
import  org.springframework.beans.factory.xml.XmlBeanFactory;
import  org.springframework.core.io.ClassPathResource;
import  org.springframework.core.io.Resource;

public   class  HelloWordSpring
{
     private  String msg;

     public   void  setMsg(String msg)
    {
         this .msg  =  msg;
    }

     public   void  sayHello()
    {
        System.out.println(msg);
    }

     public   static   void  main(String[] args)
    {
        Resource res  =   new  ClassPathResource( " com/java114/spring/test/bean.xml " );
        BeanFactory factory  =   new  XmlBeanFactory(res);
        HelloWordSpring hello  =  (HelloWordSpring) factory.getBean( " helloBean " );
        hello.sayHello();
    }

}

5. 在和HelloWordSpring.java 相同目录下面，再新建一个xml文件，名字是bean.xml, 内容如下

<? 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: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-2.0.xsd             http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd             http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd" >
  < bean  id ="helloBean"  class ="com.java114.spring.test.HelloWordSpring" >
   < property  name ="msg"  value ="simple spring demo" />
  </ bean >
</ beans >

为什么这样写，我也不知道，不管他。

6. 鼠标右键选择HelloWordSpring.java, 选择Run As - Java Applications， 得到结果：

2010-6-16 21:39:47 org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions
信息: Loading XML bean definitions from class path resource [com/java114/spring/test/bean.xml]
