该代码段展示了如何使用Java的BufferedReader和InputStreamReader处理GBK编码的CSV文件。通过指定GBK编码，能正确读取非UTF-8格式的乱码内容，逐行解析文件并分配给相应变量进行处理。

1.首先看乱码结果和代码
因为没有GBK，如何加入GBK如下

BufferedReader reader = new BufferedReader(new FileReader(file));

查看结果：

2.加入GBK

BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(file),"GBK"));

查看结果：

读入csv全部代码：

	@Test
    public  void kaihucsv() throws IOException, InterruptedException {
		//地址
        File file = new File("src/main/java/com/znzdh/until/kaihucsv.csv");
		//BufferedReader读取
        BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(file),"GBK"));
        //创建一个空的一行准备接收
        String line ="";
		//创建接收字段
