Closed 5 months ago.
I trying to learn Spring framework. I created a project using MySQL datase, Hibernate, Spring security, lombok. I'm using JDK 17, and apache-maven version 3.8.4. I started by creating the entities and adding the ManyToOne / OneToMany annotations.
When I run the project, I get this message:

Here is the code where the message shows the error;

```

```

The error message is quite exact.
Caused by: org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: com.neji.gestiondestock.model.LigneCommandeClient.idcommandeclient in com.neji.gestiondestock.model.CommandeClient.ligneCommandeClient
idcommandeclient is not a field in the java class, but rather a column in the database table. mappedby always references a field in the java class. In this case it would be commandeClient. With the annotation it is #OneToMany(mappedBy = "commandeClient")

Spring H2 Table not found

I'm getting an error which can be relieved with spring.jpa.hibernate.ddl-auto=update but I don't know why its happening. I need explanation to why its crashing and if the ddl-auto=update is the right fix for it

The physical tables your entities are mapped to need to be created somehow in your DB.
Specifying spring.jpa.hibernate.ddl-auto=update makes Hibernate auto-generate the tables based on the entities it detects in your project. (Under the hood this property is converted to Hibernate's hibernate.hbm2ddl.auto, its corresponding values are described here: https://docs.jboss.org/hibernate/orm/5.2/userguide/html_single/Hibernate_User_Guide.html#configurations-hbmddl)
For other ways to initialize DB in Spring Boot see https://docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto.data-initialization
Note that usage of any of the auto generation modes is highly discouraged in production. The proper solution for production DB initialization/migration is tools like Liquibase and Flyway.

Failed to start bean 'webServerStartStop'; Unable to start embedded Tomcat server - spring-boot-starter-web

Spring application using Maven including only Spring Web dependency gives "Unable to start embedded Tomcat serve" error.
The same project runs on other computers like expected.
Spring Boot Version: 2.4.3
Package Type: JAR
Java Version: 11
No additional code added from the starter project except to print to the console for testing.
Application runs and prints to the console like expected when tomcat is excluded int the pom.xml.
Tested multiple ports.
Tested JDK 8 and 11.

There was control software installed for the individuals Network interface controller (NIC) that allowed both ethernet and wifi to be used simultaneously. This was installed to supposedly improve gaming experience, but did not play nicely with tomcat in Spring. Once disabled the application was able to run as expected.
Edit:
A similar error occurs if your address or port is incorrect / already used. This fixes the error in most situations, but a driver like the one mentioned above may cause the error.

It got fixed for me after changing server.port to 8080 from 80.

I was trying to run spring boot on my local network and that error occurred.
The problem was a wrongly specified IP address property inside my application-dev.yml file.
server:
address: 192.168.0.107 // it needed to be 192.168.0.104
port: 8080
You can always check your IPv4 Address by running ipconfig.

Disable the Gamingservices service or go to the task manager and end the task of gamingservices and run again the application. or restart the computer.

Spring Cloud Kubernetes application does not detect when it is running in a pod

Expected Behavior
According to the Spring Cloud Kubernetes documentation, all that is necessary for a Spring application to detect when it's running in a pod is to add Spring Cloud Kubernetes to the classpath with the spring-cloud-kubernetes-all dependency.
This triggers two events:
If present the application-kubernetes.yml profile is loaded.
The Kubernetes implementation of DiscoveryClient is used for service discovery, leveraging KubeDNS instead of the default of Eureka.
This environment awareness is described here:
https://cloud.spring.io/spring-cloud-static/spring-cloud-kubernetes/1.1.0.RELEASE/reference/html/#kubernetes-profile-autoconfiguration
and here:
https://cloud.spring.io/spring-cloud-static/spring-cloud-kubernetes/1.1.0.RELEASE/reference/html/#discoveryclient-for-kubernetes
Actual Behavior
After booting the Spring Cloud Kubernetes application using the following yaml and accessing it's actuator endpoint at http://minikube-ip:port/actuator/env via a NodePort, I see there are no active profiles set, even though a application-kubernetes.yml exists in the resources folder:
{
"activeProfiles": [],
...
Upon further investigation in the http://minikube-ip:port/actuator/info endpoint, I see that the Spring application isn't aware it's in a pod at all, as evidenced by:
{
"kubernetes": {
"inside": false
}
}

Any help would be greatly appreciated! Thank you!

Are you sure you should have spring.cloud.kubernetes.enabled=false in your application.yml? If I understand the docs correctly, you need to leave it to the default value (true) in order for it to do the detection and load the kubernetes profile.
If you disable it, it will never load your application-kubernetes.yaml, so setting it to true inside that file will have no effect.
As I understand it you can turn off kubernetes features (e.g. spring.cloud.kubernetes.config.enabled=false) in your main YAML, but not the entire k8s integration if you want profile autoconfiguration to work.

Here is the application.yml, application-kubernetes.yml, and build.gradle combo that finally worked for me:

Cannot connect to jhipster spring registry on docker via IDE

I'm running JHipster registry in a docker container.
All applications running on docker can connect and register in registry endpoint (port 8761).
But when I try to connect an application running on my IDEA, I receive a error when trying to connect to the registry endpoint:

The application connects to Register (see it in logs), but after that I receive the error:
UnknownHostException: registry
Did anyone know how can I connect to a registry running in docker?
My spring application.yml is:
eureka:
instance:
prefer-ip-address: true
client:
enabled: true
healthcheck:
enabled: true
registerWithEureka: true
fetchRegistry: true
serviceUrl:
defaultZone: http://admin:admin#localhost:8761/eureka/
The default zone in jhipster-registry is http://user:pass#register:8761/eureka.
If I change to localhost, like this:
eureka:
client:
serviceUrl:
defaultZone: http://admin:admin#localhost:8761/eureka/
It works, but in this case the services running in docker can't access the registry (reverse problem).
Thanks!

I had a similar issue. In 3.5.0, I was able to successfully start the docker based registry, and then start up non docker versions of a microservice and a gateway. With 3.5.1, I was no longer able to do that, getting the same error you are getting. I think it's related to https://github.com/jhipster/generator-jhipster/pull/3848. In any case, I just added an entry in my /etc/hosts file, pointing "registry" to 127.0.0.1, and it worked.

The localhost on docker which running microservice is not the same localhost on docker which running registry. I changed the localhost to the host's Intranet Address, It's work for me.
eureka:
instance:
prefer-ip-address: true
client:
service-url:
defaultZone: http://admin:${jhipster.registry.password}#10.31.224.228:8761/eureka/
