import(
    "bufio"
    "fmt"
)
 	// 循环处理kafka消息
	path := "./1.json"
	file, err := os.Open(path)
	if err != nil {
		fmt.Println("open file failed")
	}
	
	defer file.Close()

	scanner := bufio.NewScanner(file)
	i := 1
	for scanner.Scan() {
	    i = i+1
	    fmt.Println("-----", i,scanner.Text( "-----")
	}
