java以某一編碼方式讀取CSV

1、mvn依賴

      <dependency>
          <groupId>net.sf.opencsv</groupId>
          <artifactId>opencsv</artifactId>
          <version>2.3</version>
      </dependency>

2、代碼

public List<String> readCSV(String filename) {
        CsvReader reader = null;
        FileInputStream fin = null;
        List<String> list = new ArrayList<String>();
        try {
            fin = new FileInputStream(filename);
            Charset charset = Charset.forName("gbk");
            reader = new CsvReader(fin, charset);
            while (reader.readRecord()) {
                int icount = reader.getColumnCount();//獲取一共多少列數據
                if (icount > 0) {
                    if (!list.contains(reader.get(0).toLowerCase()))//獲取第一列數據
                        list.add(reader.get(0).toLowerCase());
                }
//                String str = reader.getRawRecord();//讀取某行
//                System.out.println(str);
            }
            if (list.size() > 0) {
                if ("搜索詞".equals(list.get(0))) {
                    list.remove(0);
                }
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                if (fin != null)
                    fin.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
            reader.close();
        }
        return list;
    }
