After a few days, the Java application stops working

After a few days, the Java application stops working - spring-boot

I am writing a pet application in Java. Spring database Web.
I place all this on the server in separate docker containers.
The database is created in the docker-compose file
postgres-content:
image: postgres:14.1
container_name: content_db-v01
restart: unless-stopped
ports:
- "5532:5432"
environment:
- POSTGRES_USER=user
- POSTGRES_PASSWORD=*****
volumes:
- /home/my-db/content_db:/var/first-prj/data/content
- ./sql/create_db_catalog.sql:/docker-entrypoint-initdb.d/create_db_catalog.sql
I use liquibase to create a table. To work with the JPA database.
spring:
jpa.properties.hibernate.jdbc.lob.non_contextual_creation: true
jpa.properties.hibernate.dialect: org.hibernate.dialect.PostgreSQLDialect
jpa:
show-sql: true
hibernate:
ddl-auto: none
datasource:
initialization-mode: always
driver-class-name: org.postgresql.Driver
jdbc-url: jdbc:postgresql://postgres-content:5432/catalog_content?currentSchema=catalog&stringtype=unspecified
username: content
password: *****
liquibase:
enabled: true
change-log: classpath:db/changelog/db.changelog.xml
Everything works fine. I launch it, I check what I wrote for a day or two. But a few days pass, I connect to the server to download a new version. And my application is constantly overloaded.
Just restarting containers doesn't help.
I'm deleting the directory from the database on the server. I overload and everything works again.
The first time I thought it was an accident. But this happened the second time.
Tell me where and how to find a solution to this problem?
Where to look?

The database container is unavailable. But why did this happen? And where to look for the error?
Here are the logs of the container with the database after restarting the container. I didn't think to look before restarting.

Have you tried running it using the same network?
Add your network to your services named postgres-content and spring.
networks:
- app-network
Finally, create your network definition at the bottom of your docker-compose.yml file.
networks:
app-network:
name: app-network

I resolve problem, when fixed build section in build.gradle.kts file. Remove block tasks.withType and add build section with default spring boot builder:
tasks.named<org.springframework.boot.gradle.tasks.bundling.BootJar>("bootJar") {
mainClass.set("con.example.app.KotlinAppApplicationKt")
archiveBaseName.set("testapp")
archiveFileName.set("testapp.jar") }

Perhaps your DB container is not yet ready when the app is initialized. You may want to implement some waiting mechanism like this or like some of the solutions here.

Spring Boot with ElasticSearch in Groovy: WebClient not present Exception

I am running a small demo spring-boot application where I want to connect my url routes with elasticsearch queries. The app starts up just fine with those gradle dependencies:
implementation('org.springframework.data:spring-data-elasticsearch')
implementation('org.elasticsearch:elasticsearch')
implementation('org.elasticsearch.client:elasticsearch-rest-high-level-client')
implementation('org.springframework.boot:spring-boot-starter-web')
implementation('org.codehaus.groovy:groovy')
As soon as I add the class ElasticsearchClientConfig (not yet used by me, just loaded):
package me.spring.GroovyDemo.store
import me.spring.GroovyDemo.AppConstants
import org.elasticsearch.client.RestHighLevelClient
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.ComponentScan
import org.springframework.context.annotation.Configuration
import org.springframework.data.elasticsearch.client.ClientConfiguration
import org.springframework.data.elasticsearch.client.RestClients
import org.springframework.data.elasticsearch.core.ElasticsearchOperations
import org.springframework.data.elasticsearch.core.ElasticsearchRestTemplate
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories
#Configuration
#EnableElasticsearchRepositories(basePackages = "me.spring.GroovyDemo")
#ComponentScan(basePackages = ["me.spring.GroovyDemo"])
class ElasticsearchClientConfig {
#Bean
RestHighLevelClient client() {
ClientConfiguration clientConfiguration
= ClientConfiguration.builder()
.connectedTo(AppConstants.ELASTIC_SERVER)
.build()
return RestClients.create(clientConfiguration).rest()
}
#Bean
ElasticsearchOperations elasticsearchTemplate() {
return new ElasticsearchRestTemplate(client())
}
}
The app fails on startup.
I found many similar issues. But none of them seems to fail with missing Webclient. I don't really get that I would need a WebClient in the first place.
The exception is as follows:

Somehow I am not able to create the ES client bean.
My App is in package me.spring.GroovyDemo, everything else is below.
I tried adding some dependencies, like webflux to get WebClient, but did not really help.
What is the reason for the failing startup?

I got your example running by adding
implementation('org.springframework:spring-webflux')
Where does this reference to the WebClient class come from? Spring Data Elasticsearch is built with an optional dependency to org.springframework:spring-webflux because it contains code for both the imperative and the reactive setup. Optional because we need it to build the library, but you do not need it when running - in imperative mode.
Now the ClientConfiguration class and its builder have a method withWebClientConfigurer(Function<WebClient, WebClient> webClientConfigurer). This function is compiled into the library.
When running an imperative, non-reactive application which does not have webflux in it's classpath in Java or Kotlin everything is fine - the application itself was never compiled to use this function and so it is not needed and the transitive optional dependency is never resolved. It does not matter if these optional dependencies are in the loaded class as long as they are not used - otherwise the compiler would have complained.
In Groovy this seems to be different. Here there is some Java-bean inspection running on the ClientConfiguration class which finds the afore mentioned method but cannot find the WebClient class, because that's not on the classpath.
So by adding the dependency to the classpath this error goes away by the cost of having a library with reactive code in the classpath - now some Spring Boot austoconfiguration could be tempted to pick something up from there.
I don't know what would be a better solution, or if groovy can handle optional dependencies better, I'm not using groovy. Someone with more insights might have a better answer.

From the stacktrace follows that you should add a missing dependency to spring-web-reactive to your Gradle config:
dependencies {
//...
implementation 'org.springframework:spring-web-reactive:5.0.0.M4'
}

So a few things caught my eye here:
FROM openjdk:11-jdk-slim
...
image: cassandra:3.11.5
Cassandra version <= 3 will only run on Java 8 (or lower). It will fail to start on anything else.
Error connecting to Node(endPoint=localhost:9042,
- spring.data.cassandra.contact-points=cassandra_node_1
I'm curious as to what cassandra_node_1 resolves to, as I'm pretty sure it's not localhost. Note, that you can only connect to the endpoints that are being broadcasted by Cassandra. So if your listen_address and rpc_address are both set to localhost in your cassandra.yaml, you'll only ever be able to connect locally and only by the values of localhost or 127.0.0.1. If you need to be able to reach it remotely at cassandra_node_1 then that's what those _address properties should be set to.

Spring boot with embeded tomcat on AWS is start to fail

I was able to start it properly with same configuration and port, however suddenly its unable to start with below log. As per the log, its a Caused by: java.net.SocketException: Permission denied
However I am surprised that nothing has changed then how suddenly I am getting permission denied, not getting any further clue, can someone suggest please

You can look at this answer: Spring Boot deploy with Tomcat.
In my case; i included the tomcat dependency in the pom file;and I use 8080 as the server pot; which solves my issue.
In addition, don't forget to check your jre and jdk version.

Looks like your javax.servlet dependency is missing try to add:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>4.0.1</version>
<scope>provided</scope>
</dependency>

This worked fine for me after including the main class in a package.
Please look into:
