連接多個 MongoDB 數據庫 Java

Question

我有 2 個不同的數據庫（firstDB、secondDB），分別連接到它們每個都可以正常工作，但是如果在一個 session 我嘗試連接到第二個我得到一個錯誤，我連接到第一個沒有問題

public static MongoDatabase dbConnect() {
       System.setProperty("javax.net.ssl.keyStore", "src/main/resources/firstDB.pkcs12");
       System.setProperty("javax.net.ssl.keyStorePassword", "qwerty");
       ConnectionString connectionString = new ConnectionString(System.getenv("FirstMongoDB_DEV"));
       CodecRegistry pojoCodecRegistry = fromProviders(PojoCodecProvider.builder().automatic(true).build());
       CodecRegistry codecRegistry = fromRegistries(MongoClientSettings.getDefaultCodecRegistry(),
               pojoCodecRegistry);

       MongoClientSettings clientSettings = MongoClientSettings.builder()
               .applyConnectionString(connectionString)
               .codecRegistry(codecRegistry)
               .build();
       return MongoClients.create(clientSettings).getDatabase("firstDB");

   }

code to connect is similar for both, so if i'll call firstDB connect it work fine and if after that i call connect to secondDB i get com.mongodb.MongoSocketReadException: Prematurely reached end of stream If i swap the connections, first to the secondDB 然后到 firstDB，我會得到相同的結果

問題是 JVM 不知道如何動態更改 keyStore，幫助的庫
