在日志中：

NumberFormatException：无法将“null”解析为整数

表示您正在尝试将空值转换为整数。在将String值转换为整数之前，请检查null为空，并使用try/catch来处理NumberFormatException。

int  intnum=0;
if (strvalue !=null && !"".equals(strvalue) ){
     try {
           int  intnum = Integer.parseInt(strvalue);

         } catch (NumberFormatException e) {
            intnum=0;
            System.out.println(e.getMessage());
        }
}
else{
intnum=0;
}
