java修改conf文件内容

需求修改conf配置内容，节点内容如下
listen 1935;
max_connections 1000;
#daemon off;
#srs_log_tank console;
vhost defaultVhost {
ingest livestream {
enabled on;
input {
type file;
url rtsp://guest:[email protected]:554/stream0/low;
}
ffmpeg ./objs/ffmpeg/bin/ffmpeg;
engine {
enabled off;
output rtmp://192.168.0.45/live/10002-002-L;
}
}
ingest livestest {
enabled on;
input {
type file;
url rtsp://guest:[email protected]:554/stream0/high;
}
ffmpeg ./objs/ffmpeg/bin/ffmpeg;
engine {
enabled off;
output rtmp://192.168.0.45/live/10001-001-L;
}
}
}

创建实体对象
public class IngestModleVo {

    this.list = new ArrayList();

    return list;
