1 新建一个项目
File----->New ----->Project 在出现的对话框中选择 MyEclipse 下的 Web Project，在Project Name 输入mySpring1，其他的选项默认，再点Finish完成；
2 加入Spring 包
在myspring1 项目上点右键，选MyEclipse ---> Add Spring Capabities，再点Finish完成；
3 加入Log4j 包
菜单--->Project -->Properties-----Java Build Path 点Libraries 选项卡，再选Add External Jars 加入log4j 的jar 包 (可从网上下)http://archive.apache.org/dist/logging/log4j/1.2.8/
4 新建Action接口文件
右键点src ---->New ---->Interface (包名net.xiaxin.spring.qs)
Action.java代码
package net.xiaxin.spring.qs;
public interface Action {
public String execute(String str);
}
5 建立Action接口的两个实现UpperAction、LowerAction
LowerAction.java
package net.xiaxin.spring.qs;
public class LowerAction implements Action {
private String message;
public String getMessage() {
return message;
}
public void setMessage(String string) {
message = string;
}
public String execute(String str) {
return (getMessage()+str).toLowerCase();
}
}
/////
UpperAction.java
package net.xiaxin.spring.qs;
public class UpperAction implements Action {
private String message;
public String getMessage() {
return message;
}
public void setMessage(String string) {
message = string;
}
public String execute(String str) {
return (getMessage() + str).toUpperCase();
}
}
6 新建log4j.properties配置文件，内容如下：
log4j.rootLogger=DEBUG, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%c{1} - %m%n
7 Spring配置文件（bean.xml）
在myspring 上右击 --->New--->File 文件名 bean.xml
bean.xml 内容如下
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<description>Spring Quick Start</description>
<bean id="TheAction"
class="net.xiaxin.spring.qs.UpperAction">
<property name="message">
<value>HeLLo</value>
</property>
</bean>
<bean id="action2" class="net.xiaxin.spring.qs.LowerAction">
<property name="message">
<value>HeLLo</value>
</property>
</bean>
</beans>
8 建立测试文件SimpleTest.java
package test;
import net.xiaxin.spring.qs.Action;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
public class SimpleTest {
public static void main(String args[])
{
SimpleTest test=new SimpleTest();
test.testQuickStart();
}
public void testQuickStart() {
ApplicationContext ctx=new FileSystemXmlApplicationContext("bean.xml");
Action action = (Action) ctx.getBean("TheAction");
System.out.println(action.execute("Rod Johnson"));
action = (Action) ctx.getBean("action2");
System.out.println(action.execute("jecKj"));
}
}
9 把SimpleTeat.java 设置成主类就可以运行了，运行结果 (红色部分是想要的结果)
FileSystemXmlApplicationContext - Publishing event in context [org.springframework.context.support.FileSystemXmlApplicationContext;hashCode=12694833]: org.springframework.context.event.ContextRefreshedEvent[source=org.springframework.context.support.FileSystemXmlApplicationContext: display name [org.springframework.context.support.FileSystemXmlApplicationContext;hashCode=12694833]; startup date [Wed May 31 13:30:25 CST 2006]; root of context hierarchy]
DefaultListableBeanFactory - Returning cached instance of singleton bean 'TheAction'
HELLOROD JOHNSON
DefaultListableBeanFactory - Returning cached instance of singleton bean 'action2'
