java - 在JAVA中将CSV值转换为HashMap键值对

Question

嗨，我有一个的csv。我试图逐行读取csv并将值转换为哈希键值对。
这是代码：-

public class Example {
public static void main(String[] args) throws ParseException, IOException {
    // TODO Auto-generated method stub

    BufferedReader br = new BufferedReader(new FileReader("test.csv"));
    String line =  null;
    HashMap<String,String> map = new HashMap<String, String>();

    while((line=br.readLine())!=null){
        String str[] = line.split(",");
        for(int i=0;i<str.length;i++){
            String arr[] = str[i].split(":");
            map.put(arr[0], arr[1]);
        }
    }
    System.out.println(map);
 }
}

csv文件如下：-

1,"testCaseName":"ACLTest","group":"All_Int","projectType":"GEN","vtName":"NEW_VT","status":"ACTIVE","canOrder":"Yes","expectedResult":"duplicateacltrue"
2,"testCaseName":"DCLAddTest","group":"India_Int","projectType":"GEN_NEW","vtName":"OLD_VT","status":"ACTIVE","canOrder":"Yes","expectedResult":"invalidfeaturesacltrue"

当我运行此代码时，我得到此错误：-

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
    Example.main(Example.java:33)

谁能帮我修复代码并找出程序中的错误？

第一次拆分时，在您的字符串中仅包含arr[0]，因为1在arr[1]中没有任何内容，因此将导致异常

如果不需要1,2等。您可以查看以下代码：

        String str[] = line.split(",");
        for(int i=1;i<str.length;i++){
            String arr[] = str[i].split(":");
            map.put(arr[0], arr[1]);
        }
