java中日志的若干问题

简单记录下做日志的几个问题：

1  明确思路 

明确调用什么接口以及所需传入的参数：

     如图接口描述：

2 编写的日志工具LogUtil

    2.1 上传参数到指定接口

code如下，仅供参考。参数自定，HttpClientUtils也是自己定义的。

import net.sf.json.JSONObject;import org.apache.log4j.Logger;import javax.servlet.http.HttpServletRequest;import java.text.DateFormat;import java.text.SimpleDateFormat;import java.util.*;public final class LogUtil {private static final Logger logger = Logger.getLogger(LogUtil.class);public static final int GAMEBOX_MANAGER_SYSTEM_ID = 1;public static final int APPSTORE_MANAGER_SYSTEM_ID = 2;//调用的日志记录接口private static final String url = "*********";public static void sendLog(int systemId, int  moduleId, String objectName, String objectId, String optType,   HttpServletRequest request) {try {Map<String, String> map = new HashMap<>();map.put("systemId", String.valueOf(systemId));map.put("moduleId", String.valueOf(moduleId));map.put("objectName", objectName);map.put("objectId", objectId);map.put("optType", optType);AdminUser adminUser = (AdminUser) request.getSession(true).getAttribute("adminUser");String optAccount = "unknown";if(adminUser != null) {optAccount = adminUser.getUsername();}map.put("optAccount", optAccount);DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");String optTimeStr = format.format(new Date());map.put("optTime", optTimeStr);String result = HttpClientUtils.httpGet(url, map);JSONObject json = JSONObject.fromObject(result);if (json.getInt("code") != 1) {logger.error("提交日志异常: " + result);}} catch (Exception e) {logger.error(e);}}public static void sendLog(int  moduleId, String objectName, String objectId, String optType,  HttpServletRequest request){sendLog(GAMEBOX_MANAGER_SYSTEM_ID, moduleId, objectName, objectId, optType, request);}private LogUtil() {}}

HttpClientUtils的code如下参考：

2.2 使用输入输出流保存日志到 txt文件中

上传指定参数：

public  void saveLog(long uid, String nonce, String authcookie,long qipuId, String machineId, String resultCode){PrintStream  ps = null;File file = null;try {file = new File(LOGFILE_PATH  + "LogInfo.txt");if( !file.exists() ){file.createNewFile();}DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");String optDate = df.format(new Date());ps = new PrintStream (new FileOutputStream(file, true),true);ps.println("【Log】" + optDate + " uid:" + uid + " ,nonce:" + nonce +" ,authcookie:" + authcookie +" ,qipu_id:" + qipuId +" ,machine_id:" + machineId + " ,ajaxResult_code:" + resultCode);} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}finally{if(ps != null){try {ps.close();} catch (Exception e) {e.printStackTrace();}}}}

也可以存储URL 和 JSON 串信息来得到信息：

//暂时放在D盘private static final String LOGFILE_PATH = "D:\\";public static void saveLog(String requestUrl, String response){PrintStream ps = null;File file = null;try {file = new File(LOGFILE_PATH  + "LogInfo.txt");if( !file.exists() ){file.createNewFile();}DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");String optDate = df.format(new Date());ps = new PrintStream (new FileOutputStream(file, true),true);ps.println(optDate+ " request:"+ requestUrl + " response:" +response);} catch (FileNotFoundException e) {e.printStackTrace();}catch (IOException e) {e.printStackTrace();}finally{if(ps != null){try {ps.close();} catch (Exception e) {e.printStackTrace();}}}}

以下是存储请求信息和和一些JSON信息：

public String getItem(HttpServletRequest request, HttpServletResponse response){//省略内容...//完整的url地址：http://localhost:8080/sub.action?name=aaa&age=12String requestUrl = request.getRequestURL().toString() + "?" + request.getQueryString();String jsonResponse = createJsonResponse(....);//记录日志LogUtil.saveLog(requestUrl, jsonResponse);}

2.3 使用Log4j将信息输入到指定文件：

log4j.rootLogger=INFO, stdoutlog4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%p]%m%n# aa接口Venus日志log4j.logger.checkplay=INFO, aalog4j.appender.checkplay=org.apache.log4j.RollingFileAppenderlog4j.appender.checkplay.File=/*/*/*/info.loglog4j.appender.checkplay.MaxFileSize=1MBlog4j.appender.checkplay.MaxBackupIndex=100log4j.appender.checkplay.layout=org.apache.log4j.PatternLayoutlog4j.appender.checkplay.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %m%n

对应接口中记录日志：

org.apache.log4j.Logger logger = org.apache.log4j.Logger.getLogger("interface111");AjaxResult ajaxResult = ***;

String requestUrl = request.getRequestURI() + "?" + request.getQueryString();if(!ajaxResult.getCode().equals(ApiCode.SUCCESS)){String tempErrorJsonResponse = createErrorResponse(ajaxResult.getCode(), ajaxResult.getMsg(), request);logger.info("uid:" + uid + " request:" + requestUrl + " response:" + tempErrorJsonResponse);return tempErrorJsonResponse;}String tempSuccessJsonResponse = createSuccessResponse(ajaxResult.getData(), request);logger.info("uid:" + uid + " request:" + requestUrl + " response:" + tempSuccessJsonResponse);return tempSuccessJsonResponse;

3 遇到的困惑：

当页面中账号放入在session中，想要获取这个账号的时候：

AdminUser adminUser = (AdminUser)request.getSession(true).getAttribute("adminUser");String optAccount = adminUser.getUsername();

4 测试

当在main方法中需要测试某个方法，而这个方法又带有HttpRequest的时候，可以自行创建HttpReques，在getAttribute()方法中进行模拟:

public static void main(String[] args) {sendLog(3, "角色扮演", 104, "编辑", new Date(),new HttpServletRequest() {@Overridepublic String getAuthType() {return null;}@Overridepublic Cookie[] getCookies() {return new Cookie[0];}@Overridepublic long getDateHeader(String s) {return 0;}@Overridepublic String getHeader(String s) {return null;}@Overridepublic Enumeration getHeaders(String s) {return null;}@Overridepublic Enumeration getHeaderNames() {return null;}@Overridepublic int getIntHeader(String s) {return 0;}@Overridepublic String getMethod() {return null;}@Overridepublic String getPathInfo() {return null;}@Overridepublic String getPathTranslated() {return null;}@Overridepublic String getContextPath() {return null;}@Overridepublic String getQueryString() {return null;}@Overridepublic String getRemoteUser() {return null;}@Overridepublic boolean isUserInRole(String s) {return false;}@Overridepublic Principal getUserPrincipal() {return null;}@Overridepublic String getRequestedSessionId() {return null;}@Overridepublic String getRequestURI() {return null;}@Overridepublic StringBuffer getRequestURL() {return null;}@Overridepublic String getServletPath() {return null;}@Overridepublic HttpSession getSession(boolean b) {return new HttpSession() {@Overridepublic long getCreationTime() {return 0;}@Overridepublic String getId() {return null;}@Overridepublic long getLastAccessedTime() {return 0;}@Overridepublic ServletContext getServletContext() {return null;}@Overridepublic void setMaxInactiveInterval(int i) {}@Overridepublic int getMaxInactiveInterval() {return 0;}@Overridepublic HttpSessionContext getSessionContext() {return null;}@Overridepublic Object getAttribute(String s) {return new AdminUser() {@Overridepublic String getUsername() {return "wucao";}};}@Overridepublic Object getValue(String s) {return null;}@Overridepublic Enumeration getAttributeNames() {return null;}@Overridepublic String[] getValueNames() {return new String[0];}@Overridepublic void setAttribute(String s, Object o) {}@Overridepublic void putValue(String s, Object o) {}@Overridepublic void removeAttribute(String s) {}@Overridepublic void removeValue(String s) {}@Overridepublic void invalidate() {}@Overridepublic boolean isNew() {return false;}};}@Overridepublic HttpSession getSession() {return null;}@Overridepublic boolean isRequestedSessionIdValid() {return false;}@Overridepublic boolean isRequestedSessionIdFromCookie() {return false;}@Overridepublic boolean isRequestedSessionIdFromURL() {return false;}@Overridepublic boolean isRequestedSessionIdFromUrl() {return false;}@Overridepublic Object getAttribute(String s) {return null;}@Overridepublic Enumeration getAttributeNames() {return null;}@Overridepublic String getCharacterEncoding() {return null;}@Overridepublic void setCharacterEncoding(String s) throws UnsupportedEncodingException {}@Overridepublic int getContentLength() {return 0;}@Overridepublic String getContentType() {return null;}@Overridepublic ServletInputStream getInputStream() throws IOException {return null;}@Overridepublic String getParameter(String s) {return null;}@Overridepublic Enumeration getParameterNames() {return null;}@Overridepublic String[] getParameterValues(String s) {return new String[0];}@Overridepublic Map getParameterMap() {return null;}@Overridepublic String getProtocol() {return null;}@Overridepublic String getScheme() {return null;}@Overridepublic String getServerName() {return null;}@Overridepublic int getServerPort() {return 0;}@Overridepublic BufferedReader getReader() throws IOException {return null;}@Overridepublic String getRemoteAddr() {return null;}@Overridepublic String getRemoteHost() {return null;}@Overridepublic void setAttribute(String s, Object o) {}@Overridepublic void removeAttribute(String s) {}@Overridepublic Locale getLocale() {return null;}@Overridepublic Enumeration getLocales() {return null;}@Overridepublic boolean isSecure() {return false;}@Overridepublic RequestDispatcher getRequestDispatcher(String s) {return null;}@Overridepublic String getRealPath(String s) {return null;}@Overridepublic int getRemotePort() {return 0;}@Overridepublic String getLocalName() {return null;}@Overridepublic String getLocalAddr() {return null;}@Overridepublic int getLocalPort() {return 0;}});}
