zkoss spring configuration

ZK OSS는 Direct RIA 프레임워크다.
Direct RIA가 몬지. ZK가 몬지는 담에 기회에 있으면 포스팅하기로 하고,
이번 포스트는 zkoss에서 스프링을 사용하기 위한 설정만 살펴보기로 하자.

스프링 설정하는 건 다들 아는 것일테고, 간단히 zkoss에서 스프링 빈을 사용하는 방법에 대해서만 살펴보기로 하자.

web.xml 파일내에서 가장 중요한 것은 리스너 두개의 순서다. !!!
이거 무시하면 띠바 겁내 헤롱거릴거다!
반드시
org.zkoss.spring.web.context.CoreContextListener 먼저 설정 해주고
org.springframework.web.context.ContextLoaderListener 는 나중에 설정해 줘야한다.


나머지는 가이드 문서에 나와있는데로 설정하면 별 문제 없다.

zkoss-config.xml (web.xml 파일에서 지정한 파일)

GreetingController.java

package com.archnal.zkoss.springsample;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import org.zkoss.spring.context.annotation.EventHandler;

import org.zkoss.zk.ui.event.Event;
import org.zkoss.zul.Button;
import org.zkoss.zul.Messagebox;
import org.zkoss.zul.Textbox;

@Component("greetingController")
@Scope("desktop")

public class GreetingController extends GenericSpringComposer {
  @Autowired
  private Textbox name;
 
  @Autowired
  private Button greetBtn;

  @Override
  public void doAfterCompose(org.zkoss.zk.ui.Component comp) throws Exception {
    super.doAfterCompose(comp);
  }
 
  @EventHandler("greetBtn.onClick")
  public void showGreeting(Event event) throws WrongValueException, InterruptedException {
    System.out.println("showGreeting");
    Messagebox.show("Hello " + name.getValue() + "!");
  }
}


greeting.zul

<?page title="Greeting " contentType="text/html;charset=UTF-8"?>
<?variable-resolver class="org.zkoss.zkplus.spring.DelegatingVariableResolver"?>
<window title="Autowire ZK Components Example" border="normal"
  height="100px" width="400px" apply="${greetingController }">

  <label value="Name:"></label>
  <textbox id="name"/>
  <button id="greetBtn" label="Greet!" />
</window>

 

위와 같이 설정하면 zkoss에서 스프링 프레임워크를 마음 껏 사용할 수 있다.~~
