1. 方法

• opencsv–>CSVParser；
• commons-csv–>CSVReader；有时候文本里有逗号可能会导致错误分割

2. maven依赖

 <dependency><groupId>org.apache.commons</groupId><artifactId>commons-csv</artifactId><version>1.8</version></dependency><dependency><groupId>com.opencsv</groupId><artifactId>opencsv</artifactId><version>3.3</version>
</dependency>

3. 示例代码

• CSVReader 读取CSV

		CSVReader reader = new CSVReader(new FileReader(path));String[] nextLine;while ((nextLine = reader.readNext()) != null) {logger.info(nextLine[0]);
//		    logger.info(nextLine[1]);
//		   有几列可以读取几列。。。。}reader.close();

• CSVParser 读取CSV

try (CSVParser parser = CSVParser.parse(new File(path), Charset.forName("UTF-8"), CSVFormat.DEFAULT.withHeader())) {for (CSVRecord record : parser) {logger.info(record.get(0));
//			String col1 = record.get("1");
//		    有几列可以读取几列。。。。// ...}
} catch (IOException e) {e.printStackTrace();
}
