SM2修改密码 生成sql语句 读取txt文件

public class SM2sql {
    public static void main(String[] args){

        String inurl="E:\\sys_user.txt";
        File infile=new File(inurl);
        String outurl="E:\\sql.txt";
        File outfile=new File(outurl);
        try {
            //如果写入的文件不存在创建新文件
            if(!outfile.exists()){
                outfile.createNewFile();
            }
            //文件的输入流读取文件
            FileInputStream in=new FileInputStream(infile);
            FileOutputStream out=new FileOutputStream(outfile);
            //读文件
            BufferedReader read=new BufferedReader(new InputStreamReader(in));
            //写文件
            BufferedWriter write=new BufferedWriter(new OutputStreamWriter(out));

            String temp="";

            while((temp=read.readLine())!=null){
                //写入文件
                String[] split = temp.split(",");
                String encryption = SM2Utils.encryption(split[1]);
                temp = "update sys_user set password = '" + encryption + "' where userId = '" + split[0] + "';";
                write.write(temp+"\r\n");

                System.out.println("update sys_user set password = '" + encryption + "' where userId = '" + split[0] + "';" + "\r\n");
            }
            read.close();
            write.close();
            out.close();
            in.close();
        } catch (Exception e) {
            // TODO 自动生成的 catch 块
            e.printStackTrace();
        }
    }
