问题遇到的现象和发生背景
在命令行调用python执行结果可以在指定位置生成所需结果文件,但在java中调用python只能获得同样的输出语句,但是不生成所需结果文件,原因不明
因为所调用的python脚本是3.8版本的(Jython只支持2),所以采用RunTime.getRuntime().exec命令行方式调用python脚本
问题相关代码，请勿粘贴截图
源代码
public class LoadPython {
public static void main(String[] args) {
Process proc;
try {
proc = Runtime.getRuntime().exec("python E:\\develop\\tmp\\tang2\\documents\\customers\\dist\\GM_APP_InputTest.py runSimulation \'{\"baseData\":{\"userId\":100,\"age\":24,\"height\":175,\"weight\":98,\"tdi\":66,\"glycuresisType\":1,\"hba1c\":25},\"events\":[{\"cho\":{\"timeStart\":\"10:30\",\"timeEnd\":\"10:00\",\"type\":1,\"data\":20}}]}\'");// 执行py文件
//用输入输出流来截取结果
BufferedReader in = new BufferedReader(new InputStreamReader(proc.getInputStream()));
String line = null;
while ((line = in.readLine()) != null) {
System.out.println(line);
}
in.close();
proc.destroy();
} catch (IOException e) {
e.printStackTrace();
}
}
}
运行结果及报错内容
命令行响应结果

我的解答思路和尝试过的方法
两者运行输出结果一致,命令行可以生成这个adult#average.csv文件,但是java的runtime始终无法生成目标文件
我想要达到的结果
在哪里做出修改,可以使java中调用python生成文件
