前面兩種可以設置編碼格式。
1.第一種：xml文件的讀取和Sax解析
InputSource inputSource = new InputSource(new FileInputStream(file));
inputSource.setEncoding("UTF-8");
List<Map<String, String>> list = reader.getList(file);
public static List<Map<String, String>> getList(File file) throws Exception{
InputSource inputSource = new InputSource(new FileInputStream(file));
inputSource.setEncoding("UTF-8");
SAXParserFactory sf = SAXParserFactory.newInstance();
SAXParser sp = sf.newSAXParser();
XML_LOG_READ_OUT reader = new XML_LOG_READ_OUT();
sp.parse(inputSource, reader);
return reader.getList();
}
2.第二種：TXT文件讀取和解析
InputStreamReader read = new InputStreamReader(new FileInputStream(file),"UTF-8");
BufferedReader br= new BufferedReader(read);//BufferedReader讀取文件
String s = null;
int i = 0;
while((s = br.readLine()) != null){
if(i > 0){
Map<String, String> map = new HashMap<String, String>();
String[] str = s.split("\t");//根據tab鍵划分
}
}
i++;
}
br.close();
}
3,第三種txt文件讀取
BufferedReader br = new BufferedReader(new FileReader(file));//構造一個BufferedReader類來讀取文件
String s = null;
int i = 0;
while((s = br.readLine())!=null){//使用readLine方法，一次讀一行
if(i>0){
String[] str = s.split("\t");
String time = str[0].replace("/", "-");
SimpleDateFormat sdfInput = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = sdfInput.parse(time);
result.append(System.lineSeparator()+"時間是："+sdfInput.format(date));
}
i++;
}
br.close();
}
