Spring-简单bean的配置（使用bean.xml手动完成）

PersonService.java:
package com.sw.servc;

public interface PersonService {

void save();

}

package com.sw.service.impl;

import com.sw.servc.PersonService;

public class PersonServiceBean implements PersonService {
/* (non-Javadoc)
* @see com.sw.service.impl.PersonService#save()
*/
@Override
public void save(){
System.out.println("save()");
}
}
