HelloWorldService

package egovframework.guide.helloworld;

public interface HelloWorldService {
 public String sayHello();
}

HelloWorldServiceImpl

package egovframework.guide.helloworld;

public class HelloWorldServiceImpl implements HelloWorldService{

 private String name;
   
 public void setName(String name) {
  this.name = name;
 }

 public String sayHello() {
  return "Hello " + name + "!!!" ;
 }
}

common-servlet.xml :  helloworld를 name 속성으로 서비스 구현클래스를 정의하고 있으며 해당 서비스의 name 속성을 “egov framework”로 선언하였다.
