HtmlUnit ErrorLog 안보이게 설정하기

HtmlUnit을 사용하다보면 errorLog가 콘솔창에 찍히는 경우가 있다.

그럴때는 아래와 같이 하면 콘솔창에 로그가 찍히지 않는다.

1 2	java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(java.util.logging.Level.OFF); java.util.logging.Logger.getLogger("org.apache.http").setLevel(java.util.logging.Level.OFF);

아래는 적용된 소스이다.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

public static void saveHtml(String url, String fileName) throws IOException {     URLEncoder.encode(url, "UTF-8");               // HtmlUnitError Log off 처리     java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(java.util.logging.Level.OFF);     java.util.logging.Logger.getLogger("org.apache.http").setLevel(java.util.logging.Level.OFF);           WebClient webClient = new WebClient(BrowserVersion.CHROME);     webClient.setCssErrorHandler(new ErrorHandler() {         @Override         public void warning(CSSParseException arg0) throws CSSException {             return;         }                   @Override         public void fatalError(CSSParseException arg0) throws CSSException {             return;         }                   @Override         public void error(CSSParseException arg0) throws CSSException {             return;         }     });     webClient.addRequestHeader("Accept-Language", "ko-KR,ko;q=0.8,en-US;q=0.6,en;q=0.4, value");     webClient.addRequestHeader("Accept-Charset", "windows-949,utf-8;q=0.7,*;q=0.3");     webClient.getCookieManager().setCookiesEnabled(true);           WebRequest webRequest = new WebRequest(new URL(url));     HtmlPage page = webClient.getPage(webRequest);           FileUtil.createFile(fileName, page.asXml());           while(true) {         File f = new File(fileName);         if(f.isFile()) break;         System.out.print(".");     }     //System.out.println(fileName + " created!!"); }

참고로 위 소스중에 FileUtil.createFile 부분은 아래내용이다.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

public static boolean createFile(String fileName, String fileText) {     return createFile(fileName, fileText, "UTF-8"); }   public static boolean createFile(String fileName, String fileText, String charset) {     File f = new File(fileName.substring(0, fileName.lastIndexOf(File.separator)));     if(!f.isDirectory()) f.mkdirs();           BufferedWriter bw = null;     try {         bw = new BufferedWriter(new FileWriterWithEncoding(fileName, charset));                   bw.write(fileText);         return true;     } catch (IOException e) {         // TODO Auto-generated catch block         e.printStackTrace();     } finally {         try { bw.close(); } catch(Exception ex) {}     }           return false; }

결론은 

java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(java.util.logging.Level.OFF);

java.util.logging.Logger.getLogger("org.apache.http").setLevel(java.util.logging.Level.OFF);

와 같이 하면 에러로그가 발생하지 않는다.
