简单读取CSV文件

java简单实现CSV的读取：

 

1.依赖的jar：opencsv-2.3.jar, rt.jar或者更高

 

2代码如下：

 

public void readCSV(File csvFile) {

       try {

             CSVReader reader = new CSVReader(new FileReader(csvFile));

             String[] nextLine = reader.readNext();   //header line

              //读取头文件

              if (!nextLine[0].trim().toLowerCase().equals("title") ||
                    !nextLine[1].trim().toLowerCase().equals("title") ||
                    !nextLine[2].trim().toLowerCase().equals("title") ||
                    !nextLine[3].trim().toLowerCase().equals("title") ||
                    !nextLine[4].trim().toLowerCase().equals("title")) {
                throw new Exception("format error");
              }

 

              // 读取值
              while ((nextLine = reader.readNext()) != null) {
                       String xxx= nextLine[0].trim();
                       String xxx= nextLine[1].trim();
                       String xxx= nextLine[2].trim();
                       String xxx= nextLine[3].trim();
                       String xxx= nextLine[4].trim();

                       // 保存到数据库

                       model.save();

              }

       } catch (Exception e) {

       }

}
