如何解决使用 Spring Boot 动态创建 mongoDB 集合并插入 json 数组数据
我已经实现了一个 spring boot 应用程序来将所有从文件中检索到的数据放入一个 JSON 数组中。由于文件太多,它会生成多个 JSON 数组。我修改了代码以将文件名存储在一个 MongoDB 集合中。它工作正常。
以下是代码。
@SpringBootApplication
@CrossOrigin(origins = "*",maxAge = 3600)
@RestController
@RequestMapping("/api/auth/logFile")
public class SpringBootSecurityJwtMongodbApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootSecurityJwtMongodbApplication.class,args);
}
@Bean
public ApplicationRunner runner(FTPConfiguration.GateFile gateFile) {
return args -> {
List<File> files = gateFile.mget(".");
for (File file : files) {
JSONArray arr = new JSONArray();
System.out.println("Result:" + file.getAbsolutePath());
run(file,arr);
}
};
}
void run(File file,JSONArray arr) throws IOException {
SimpleDateFormat formatter = new SimpleDateFormat("hh:mm:ss");
Pcap pcap = Pcap.openStream(file);
JSONObject obj = new JSONObject();
String fileName = file.getName();
pcap.loop(
packet -> {
String Time = null;
String Source = null;
String Destination = null;
String dataProtocol = null;
Long Length = null;
if (packet.hasProtocol(Protocol.TCP)) {
TCPPacket packet1 = (TCPPacket) packet.getPacket(Protocol.TCP);
Time = formatter.format(new Date(packet1.getArrivalTime() / 1000));
Source = packet1.getSourceIP();
Destination = packet1.getDestinationIP();
dataProtocol = packet1.getProtocol().toString();
Length = packet1.getTotalLength();
} else if (packet.hasProtocol(Protocol.UDP)) {
UDPPacket packet1 = (UDPPacket) packet.getPacket(Protocol.UDP);
Time = formatter.format(new Date(packet1.getArrivalTime() / 1000));
Source = packet1.getSourceIP();
Destination = packet1.getDestinationIP();
dataProtocol = packet1.getProtocol().toString();
Length = packet1.getTotalLength();
} else {
System.out.println("Not found protocol. | " + packet.getProtocol());
}
obj.put("Time",Time);
obj.put("Source",Source);
obj.put("Destination",Destination);
obj.put("Protocol",dataProtocol);
obj.put("Length",Length);
arr.add(obj);
return packet.getNextPacket() != null;
}
);
System.out.println(arr);
System.out.println(fileName);
//save file name into LogFile Collection
Calendar calendar = Calendar.getInstance();
Date Now = calendar.getTime();
logfileRepo.save(new LogFile("",fileName,Now)); //(id,file name,date)
}
@Autowired
private LogFileRepository logfileRepo;
}
现在我想修改代码来为每个 JSON 数组自动创建集合。这些集合名称应该是每个文件名的对象 ID。 有人能帮我解决这个问题吗?
