Spring简单的例子:

wangshigeyao

Spring简单的例子:

1.interface:
   package com.houyawei;
   public interface Action {
     public String execute(String str);
   }
2.实现接口的类：LowerAction 和 UpperAction:

  package com.houyawei;
  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();
  }
}
package com.houyawei;
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();
}
}
2.xml配置文件：bean.xml



Spring Quick Start

  
   HeLLo,
  

  
  
   hello,
  



4.测试类 SampleTest :
package test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
import com.houyawei.Action;
public class SampleTest {
/**
  * @param args
  */
public static void main(String[] args) {
  // TODO Auto-generated method stub
  ApplicationContext ctx=new
  FileSystemXmlApplicationContext("bean.xml");
  Action action = (Action) ctx.getBean("upperaction");
  System.out.println(action.execute("wangshigeyao"));
  
  Action action2 = (Action) ctx.getBean("loweraction");
  System.out.println(action2.execute("wangshigeyao"));
}
}

5.程序代码结构：
