일하다가 이것때문에 시간을 마니 잡아먹어서 기억할 겸 메모한다.
처음에는 org.apache.xerces.dom.DocumentImpl와 org.w3c.dom.Document, DOMImplementationRegistry, DOMImplementationLS 를 사용했는데(how-can-i-build-an-html-org-w3c-dom-document),
라이브러리가 꼬여서 다른방법이 없나 찾아보다가 DocumentBuilder,TransformerFactory를 사용하는 방법으로 구현했다.

import java.io.StringWriter;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.transform.OutputKeys;

import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

import org.w3c.dom.Document;
import org.w3c.dom.Element;

public class CustomTest {

	public CustomTest() {
		
	}
	public String makeElement() {
		StringBuffer sb = new StringBuffer();
		
		DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
		DocumentBuilder builder = null;
		try {
			builder = factory.newDocumentBuilder();
		} catch (ParserConfigurationException e) {
			e.printStackTrace();
		}
		Document htmlDoc = builder.newDocument();
        Element ulElement = htmlDoc.createElement("ul");
        Element liElement = htmlDoc.createElement("li");  
        Element aElement = htmlDoc.createElement("a");
        aElement.setAttribute("href", "#none");
    	aElement.setTextContent("Test");
    	liElement.appendChild(aElement);
    	ulElement.appendChild(liElement);
        TransformerFactory transFactory = TransformerFactory.newInstance();
        Transformer transformer =null;
        StringWriter buffer = null;
		try {
			transformer = transFactory.newTransformer();
			buffer = new StringWriter();
			transformer.setOutputProperty(OutputKeys.INDENT, "yes");
	        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
	        transformer.transform(new DOMSource(ulElement),
				      new StreamResult(buffer));
		} catch (TransformerConfigurationException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		} catch (TransformerException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
       
        sb.append(buffer);
		return sb.toString();
		
	}
	
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		CustomTest cm = new CustomTest();
		System.out.println("start!!");
		//StringBuffer sb = new StringBuffer();
		//sb.append(menu.getHtmlHelpPage(""));
		System.out.print(cm.makeElement());
	}

이클립스에서 한번에 UTF-8 인코딩 설정하기

December 18, 2016dogearpoteto7

이클립스 환경셋팅 셋팅 중인데, UTF-8 인코딩설정이 필요해서 구글링해보니 역시 어떤 훌륭하신 분이 친절하게 설명해주셨다.

goorm.io + devpack(Obics) + Spring boot

December 13, 2016PaaPpoteto7

웹IDE : goorm.io
PaaP : devpack(Obics)
웹서비스 : Spring boot

테스트 삼아서 위의 셋업으로 개발환경을 구성

잘안되는 문제가 발생하면 구글링을 통해서 도움을 많이 받았으므로,
대표적으로 도움받은 사이트를 링크한다.

중간에 이상한 문제들이 많았는데, 이런 문제를 해결하는게 갈 수록 힘들다.
그냥 서비스 개발에만 치중하고 싶다.

구름IDE에서 소스컴파일, 실행하는 명령어
mvn clean package && java -jar target/gs-rest-service-0.1.0.jar

구름IDE에서 devpack로 푸쉬하는 명령어
cf push sample(서비스이름) -p target/gs-rest-service-0.1.0.jar

cloudpack가입하고 devpack신청하는 법
devpack을 신청하려면 먼저 cloudpack에 가입하고 ucloud server 상품신청해야함.
상품을 신청했다고 해서 돈을 내는 건 아니고 웹서비스에서 사용할 각 서버등을 신청해야만 그때부터 돈이 나간다. 신용카드 정보를 기입해야하므로 참고
그리고나서 devpack을 신청한다. 낮은 서비스는 가격이 낮아서 테스트용을 쓸해보인다.
devpack에 push한 후 웹서비스가 실행안되고 에러발생
Caused by: java.lang.IllegalArgumentException: Cannot instantiate interface org.springframework.context.ApplicationContextInitializer : org.cloudfoundry.reconfiguration.spring.CloudPropertySourceApplicationContextInitializer
Caused by: java.lang.ClassNotFoundException: org.springframework.context.ApplicationContextInitializer
해결방법 : 어이없게도 Spring Boot 버전 때문에 발생한 문제로 pom.xml에서 org.springframework.boot 버전을 1.4.2.RELEASE –> 1.3.7.RELEASE 변경

Apache-Tomcat 로드밸런싱 및 세션 클러스터링 설정하기

November 30, 2016Uncategorizedpoteto7

아주 잘 정리된 문서를 보면 꼭 스크랩해 놓고싶다.

더군다나 이해하기 쉽게도 적어놓으셨다.

대단하신 분인듯

2.Apache Web server설정
3.Tomcat Application Server 설정
4.Web Application에 Clustering이 가능하도록 설정
5.Clustering Test
