kandi X-RAY | socketstream Summary
SocketStream is a framework for Realtime Web Apps. Live demo | Documentation. For existing SocketStream installations you may want to remain on 0.4.5 for a while. It is the most backwards compatible and robust and well covered by tests. It should be ready for production. The coming releases will see a lot of changes to accommodate new transport options modern browsers and mobile apps. The API will remain largely the same, but there are bound to be some changes.

I try to figure out why the communication between dockerized Spring boot app and mongoDB is not working. First things first: The whole microservice is running localy perfectly. I create an application.properties with the profile name docker: application-docker.properties

I have Maven Multi-Module application(Spring Boot + MySql + MongoDB) with using docker image, but i can't get connection to MongoDB.
Thing is when local mongo instance "MongoDB Server on Windows Services" is turned on and use spring.data.mongodb.host=localhost all is working fine.
But when I turn off mongo instance and try to go with: spring.data.mongodb.host=$(MONGO_HOST) to use it with docker I'm getting error "Exception opening socket"
I start my application with execute command: mvn install and tryed with docker-compose up --build

QUESTION
I'm working on a Testproject, where I want to exchange information via peer-to-peer from one Mobile device to another.
My goal is to make a little chat widget, where when you post a message, you can see it on all devices, which are connected, a bit like this: So if I have one Mobile device, where I send the message, it's seen by all devices.
The reason why I'm asking for help here, is because I've looked around and found two options for peer-to-peer in Flutter: A faulty example of a peer-to-peer connection in Flutter, with practically no documentation
A better-documented example of peer-to-peer connection in Flutter, which also doesn't seem to work.
According to some people, the first option doesn't even work anymore. I've tried both and neither of them managed to achieve what I wanted. It's possible that I don't understand the difference between them 100%.
With this I don't even know really, how to write the Dart/Flutter code, to test the connection between two devices.
I have experience with using Sockets and socketstreams on Java, where one device would send something into the socket stream and the other read it out of the socket stream, but there one device was server and one client.
It would really help me if you could write a simple model, where this peer-to-peer connection works. Because the "documentation" available isn't helping me at all.
Here is the non functioning code, which I have so far
...ANSWER
Answered 2022-Jan-27 at 14:18There were multiple problems here:
- Not all permissions were given, as kindly pointed out by @TheFunk
- Huawei P40 Pro doesn't have google services, thus not communicating properly via Peer To Peer
- List item
- I was using the P2P strategy STAR, instead of cluster, which now seems to work.
- My focus on NFC was wrong, because it doesn't matter if the device has NFC or not.
- My assumption that both devices need the same userName seems to be wrong. They can be different, as long as they're declared to find each EndPointId.
Note:
This question is one of two, which are about the same nearby_connections library of Flutter.
For me this question has been solved and if you have trouble finding a working code you should check out this question, where I've posted the entire connection code, which works but does not yet receive packages.

QUESTION
I was given an application after half development, and I had to finish the development, but because of licensing issues, I was asked to remove mongodb and use couchdb instead. Now, I have removed all instances of mongodb connections in the code, removed mongo connection properties from application.properties, but I still keep getting the following error when I start the spring application.

QUESTION
I'm using Spring Boot v2.6.2 and Java v17 and trying to test my MongoConnection without having a MongoDBService running because it should be tested with embedded in-memory MongoDB on the build machine, no need to set up an extra MongoDB service there. For sure on the productive system, it should use a full MongoDB.
I try to get this easy example running:
...ANSWER
Answered 2022-Jan-20 at 11:08The documentation states:
2.2.4. Embedded Mongo
Spring Boot offers auto-configuration for Embedded Mongo. To use it in your Spring Boot application, add a dependency on de.flapdoodle.embed:de.flapdoodle.embed.mongo and set the spring.mongodb.embedded.version property to match the version of MongoDB that your application will use in production. The default download configuration allows access to most of the versions listed in Embedded Mongo’s Version class as well as some others. Configuring an inaccessible version will result in an error when attempting to download the server. Such an error can be corrected by defining an appropriately configured DownloadConfigBuilderCustomizer bean.
The port that Mongo listens on can be configured by setting the spring.data.mongodb.port property. To use a randomly allocated free port, use a value of 0. The MongoClient created by MongoAutoConfiguration is automatically configured to use the randomly allocated port. If you do not configure a custom port, the embedded support uses a random port (rather than 27017) by default.
If you have SLF4J on the classpath, the output produced by Mongo is automatically routed to a logger named org.springframework.boot.autoconfigure.mongo.embedded.EmbeddedMongo.
You can declare your own IMongodConfig and IRuntimeConfig beans to take control of the Mongo instance’s configuration and logging routing. The download configuration can be customized by declaring a DownloadConfigBuilderCustomizer bean.
Therefore add the below dependency in scope:test if you want it to only be applied for Tests.
QUESTION
I've been fighting with this problem for weeks and still couldn't find what I'm doing wrong to be honest.
I have a basic springboot service supposed to connect MongoDB container. When I'm running the service locally (without Dockerised) it works fine but if I run the service and MongoDB in containers, I get MongoSocketOpenException with a connection refused.
Here is my Dockerfile

QUESTION
when I build my docker image and run it it gives this and error however if I run the jar file everything runs fine if I had it guess it would have to do with my docer-compose.yml file but idk
...ANSWER
Answered 2021-Nov-13 at 20:43You must use docker internal host network to connect with mongodb. So from your dockerized application you have to connect with the service name (as that is the hostname) instead of connecting with localhost. In your case: http://mongodb:27017 is the service (and thus hostname) of your mongo db container.

...ANSWER
Answered 2021-Sep-23 at 17:49What's the IP address of your Docker host machine?
Your app tries to connect to Mongo using localhost. Depending on what Docker installation you are using (taking the problem into account I assume Docker Toolbox), localhost won't work. You might try the IP address of Docker host instead of localhost. Most of the times, the IP is 192.168.99.100 but could be something else as well.
You can find the address by executing docker-machine ip using Docker command line.

...ANSWER
Answered 2021-Sep-23 at 14:06To help others who may have this same problem, you have 2 options to set up correctly:
Create a docker network and start all the containers on this network so that the containers can discover each other, the default is the bridge network type. In this case, the containers are isolated from the host networking interface and can't be accessed via
"localhost".If you want the containers to run on the host network and be accessible via the host network interface aka
localhostor a host IP, do as docker suggests in it's official docs here: https://docs.docker.com/network/host/
