本文探讨了Java中日志处理的一些关键问题，包括如何使用LogUtil工具类上传参数到接口，利用输入输出流保存日志到txt文件，以及Log4j配置写入指定文件。在实践中遇到的困惑，如从session中获取账号，以及在测试中模拟HttpRequest的getAttribute()方法也进行了说明。
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。

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=12
String 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, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%p]%m%n
# aa接口Venus日志
log4j.logger.checkplay=INFO, aa
log4j.appender.checkplay=org.apache.log4j.RollingFileAppender
log4j.appender.checkplay.File=/*/*/*/info.log
log4j.appender.checkplay.MaxFileSize=1MB
log4j.appender.checkplay.MaxBackupIndex=100
log4j.appender.checkplay.layout=org.apache.log4j.PatternLayout
log4j.appender.checkplay.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %m%n
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:
