首先介绍日志写入数据库：
entity:
public class DataLog extends StringIdVO{
private String dataType;
private Integer pageNum;
private Integer pageSize;
private Integer pageCount;
private Integer successNum;
private String failedIds;
private String failedReasons;
private String flag;get/ set省略..........
service:
@Transactional()
public interface DataLogService extends BaseService<DataLog> {public void addLog(DataLog log);
}
DataLogServiceImpl:
@Override
public void addLog(DataLog log) {
dao.insert(log);
}
使用：set进数据库 ....
DataLog log = new DataLog();
log.setId(GeneratorUUID.uuid());
log.setCreateDate(new Date());
log.setDataType(dataType.name());
log.setFailedIds(failedMessage.toString());
log.setSuccessNum(successNum);
log.setFlag("1");
log.setPageNum(pageNum);
log.setPageSize(PAGE_SIZE);
log.setPageCount(pageCount);
log.setFailedReasons(allReasons.toString());
logService.addLog(log);//调用service实现存入数据库
System.out.println("type:" + dataType.name() + ",pageNum::" + pageNum + ",pageSize+::" + PAGE_SIZE
+ ",successNum::" + successNum);
太简单了，看看下边封装好的Util,实现日志存在本地文件夹 ，路径为String dir = "E:\\uploadLog";
后台打印的工具类：
public class CreateLogUtil {
public static void main(String[] args) {
FileWriter fw = getFileWriter(System.currentTimeMillis()+".txt");
writeLog(fw, "123");
writeLog(fw, "456");
closeFileWriter(fw);
}
/**
* 打开日志记录文档
* @param fileName
* @return
*/
public static FileWriter getFileWriter(String fileName) {
String dir = "E:\\uploadLog";
File folder = new File(dir);
if (!folder.exists()) {
folder.mkdirs();
}
File logFile = new File(dir +"\\" + fileName);
FileWriter fw = null;
try {
if(!logFile.exists()) {
logFile.createNewFile();
}
fw = new FileWriter(logFile);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return fw;
}
/**
* 记录日志
* @param fw
* @param log
*/
public static void writeLog(FileWriter fw, String log) {
try {
fw.write(log + "\r\n");
fw.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**
* 关闭日志记录文档
* @param fw
*/
public static void closeFileWriter(FileWriter fw) {
try {
fw.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
