1.

 public class DbUtils {

     public static MongoCollection<Document> getMongoCollection(String localhost, int port) {
         MongoClient mongoClient = new MongoClient(localhost, port);
         MongoDatabase mongoDatabase = mongoClient.getDatabase("admin");
         System.out.println("Connect to database successfully");
         MongoCollection collection = mongoDatabase.getCollection("person");
         return collection;
     }
 }

2.

 public class ListEnterpriseAdapterDaoImpl  implements ListEnterpriseAdapterDao{

     @Override
     public void saveEnterprise(List<Enterprise> enterpriseList,long projectId) {

         MongoCollection<Document> collection =  DbUtils.getMongoCollection("127.0.0.1",27017);
         log.info("数据开始保存的mongoDB...............");
         for(Enterprise enterprise:enterpriseList){
             String jsonData =  JSON.toJSONString(enterpriseList);
             Random random = new Random();
             long fid = random.nextLong();
             long fTenantId = random.nextLong();
             Document document = new Document();
             document.append("F_ID", fid);
             document.append("F_PROJECT_ID", projectId);
             document.append("F_RAW_DATA", jsonData);
             collection.insertOne(document);
         }
         log.info("数据开始保存的mongoDB结束...............");
