spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.properties.show-sql = true
spring.jpa.properties.hibernate.format_sql = true
server.port=8090
The problem that I can't access to my controllers or send any requests I tried all the Ports and all the names ( localhost, booking, app ) and always CONNREFUSED
http://mysqldb:8080/hikes
http://mysqldb:8090/hikes
http://mysqldb:8091/hikes
http://localhost:8080/hikes
http://localhost:8090/hikes
http://localhost:8091/hikes
By the way when I run it without the container everything work fine.

Try to change these port numbers with the same port number
dockerfile -> EXPOSE 8080 -> EXPOSE 8090
docker-compose.yml -> ports: - 8091:8091 -> ports: - 8090:8090
this will work because your application using 8090 port and you using 8091 to run your application in your docker-compose, and at the same time trying to expose with 8080 port

Not able to start Klov Server for extent reports from a jar file

I try to install klov-0.2.5.jar locally, my settings are as below:

I dealt with it by:
running the newest ver of klov in docker container
then I copied the klov.jar file from container to my local path
same properties, mongoDB 5.0.9
typed java -jar -klov.jar
all started with no issues

Communications link failure , docker-compose

i have a problem with docker compose when i try to run docker-compose every time i get the following error i tried many solutions but nothing helps. Please help.
I will add that I created the docker image using Cloud Native Buildpacks. I used the command:
mvn spring-boot: build-image -Dspring-boot.build-image.imageName = jakuczczubak/infrastock
and then uploaded the image to dockerhub
dockerhub: dockerhub

Do you have any idea how to fix this kind of error? I've tried with a lower java/maven/spring-boot versions but without success.

The solution is trivial. I forgot about web dependency and the application has been finished immediately.
Just add to your pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>

Exception using DB2 Wirelistener (NoSQL) from a Spring Boot application

I have set up DB2 as NoSQL storage (following https://www.ibm.com/developerworks/data/library/techarticle/dm-1306nosqlforjson4/index.html). The premise by IBM is that any application talking to MongoDB can switch to DB2 if we add the Wire Listener in between.
The layout is: Client app ----> Wire listener ----> DB2
Wire listener is started with the following command:
wlpListener -start -mongoPort 27017 -userid <user> -password <password> -dbName jsondb -logPath c:/temp/logs -host 10.0.0.6:50000
The solution works fine with a simple Python client:
from pymongo import MongoClient
client = MongoClient('10.0.0.6', 27017)
database = client['jsondb']
coll = database.mycollection
coll.insert_one({"name":"Jerry","age":5})
print(coll.find_one({"name": "Jerry"}))
However, when I use a Spring Boot application designed for MongoDB (using Spring Data JPA) I get the following exception during initialization:

As if there was an incompatibility between the Mongo driver and what the Wire Listener expects.
Versions:
Host system: Windows 10
Database server: DB2/LINUXX8664 11.5.5.0 (using the Docker container from https://hub.docker.com/r/ibmcom/db2 )
IBM DB2 NoSQL WireListener 1.4.0.0 build 1.4.118
IBM DB2 NoSQL JSON 1.1.0.0 build 1.4.249
Java application (1.8 jdk), Spring Boot 2.4.2, [Mongodb.bson, mongodb-driver-core, mongodb-driver-sync] 4.1.1.

This is a bug in the Wire Listener.
The MongoDB driver expects an Int:
private static int getMinWireVersion(final BsonDocument isMasterResult) {
return isMasterResult.getInt32("minWireVersion", new BsonInt32(getDefaultMinWireVersion())).getValue();
}
private static int getMaxWireVersion(final BsonDocument isMasterResult) {
return isMasterResult.getInt32("maxWireVersion", new BsonInt32(getDefaultMaxWireVersion())).getValue();
}
But the Wire Listener is reporting a Double.

I would suggest to get latest IBM DB2 NoSQL WireListener from IBM Support that contains fix of this issue.
If you have no issue in downloading quick fix from github, you can download and use this file: https://github.com/ibmdb/db2drivers/blob/main/db2NoSQLWireListener1.4.119.zip
it contains fix of this issue. Thanks.
