extShutdownHook Spring boot JAR file AWS EC2 deployment error - java

I am now making Spring boot based Web project.
When using AWS EC2 ubuntu for deployment, unsolved error came out and I want to share.
Project stack: Spring boot + AWS (EC2, S3, RDS(MariaDB))
Deployment is run by ubuntu with Spring boot JAR file.
java -jar *.jar
The problem is whenever I start application by JAR file, the server immediately stops with this log. I thought it is because of WebSocketConfig.java for Chat messaging function, but even I added Threadpoooltaskschedule and STOMP setAllowedOrigins, symtoms still exists.
Exhausted with solving by own, I need some help from you guys.
WebSocketConfig.java

The easiest way to put a Spring BOOT app on an EC2 instance is to use Elastic Beanstalk. Read this AWS doc for more details - https://aws.amazon.com/blogs/devops/deploying-a-spring-boot-application-on-aws-using-aws-elastic-beanstalk/

What is the principle that data is transferred to reader -> processor -> writer in spring batch?

In my case, I'm implementing batch program that manages dormant accounts
My problem is this. The internal logic of the processor and the writer is not executed.
First of all, I thought about why the processor is not working. After thinking for a long time, I thought that the logic in the processor was not implemented because the data that the reader brought was not transferred to the processor.
For example, In for If the size of the repeat statement is 0, the repeat statement does not rotate at all
Usually, when transferring data from a function to a function, a parameter is used, but there is no such parameter in a batch
That's why I'm posting questions. I wonder how the data goes in order in the rotation of the batch leading to reader -> processor -> writer.
I think it's like bringing Step to StepBuilder and putting reader, processor, and writer together in one bundle and sending and receiving data in it. It is right?
Below is my code that has a problem. Please check if there is a problem with the report.

The problem has been solved. In Step properties, the allowStartIfComplete property is given as true, so it works normally. But the question is still valid. I want to know how the data moves in the rotation of reader->processor->wrtier.

JAR file automatically terminates on remote Ubuntu server after a day

I have a jar file, which was built using maven (the app is spring-boot). I deployed it on a remote server using nohup java -jar app.jar command. It works for a day or so and then stops working. The logs in nohup file are not informative and I could not figure out what's the reason for that. By stops working, I mean - the application just terminates, it is not working.
Here is the output of the nohup file:

Repository returns empty list from PostgreSQL database

My Spring Boot Application connects to a PostgreSQL database but it didn't create the tables which i have implemented as entities. That's why I set up the tables by myself with test data.
When I use dataRepository.findAll() to access the data, it returns an empty list.
So as far as I understood, I think it connects to my database, because I get no errors, but it looks like the schemas don't work properly.
I'm pretty sure this is a "configuration" problem, but I was not able to figure out what it is.
PS: I have another project with quite the same settings and code(just another database on the same server) which works perfectly fine.
My gradle.build file:
plugins {
id 'org.springframework.boot' version '2.1.6.RELEASE'
id 'java'
}
apply plugin: 'io.spring.dependency-management'
apply plugin: 'war'
group = 'de.dari'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '8'
repositories {
mavenCentral()
maven { url "http://htmlunit.sourceforge.net" }
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
implementation 'org.springframework.boot:spring-boot-starter-web'
//implementation 'org.springframework.boot:spring-boot-starter-data-rest'
compile("net.sourceforge.htmlunit:htmlunit:2.35.0")
compileOnly 'org.projectlombok:lombok:1.18.8'
annotationProcessor 'org.projectlombok:lombok:1.18.8'
runtimeOnly 'org.postgresql:postgresql'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
My application.properties file:
spring.datasource.url=jdbc:postgresql://webaddress.com:5432/b-one
spring.datasource.username=username
spring.datasource.password=secretPassword
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
An Example Entity:
#Entity
public class Data {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#NotNull
private String value;
/*
* Blank Constructor + Getters and Setters down here
*/
}
Simple CRUD-Repository:
public interface DataRepository extends CrudRepository<Data, Long> {
}
Controller:
#Autowired
DataRepository dataRepository;
#GetMapping("/test")
public String test() {
return dataRepository.findAll().toString();
}
Yeah so I don't get any error messages and the logs weren't helpful for me but maybe you want to get a glimpse on them.

spring RequestMappingHandlerMapping not working

I´m starting with Spring Boot for that I´m following a tutorial. In the tutorial, they created the controller with the #RequestMapping and GET method, once they have run the application, in the console is displayed something like this:
s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/rooms], methods
= GET}" onto java.util.List<..//more lines
But in my case I got an error:
s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/error]}" onto
public
org.springframework.http.ResponseEntity>
org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)
Why the Mapping is not created?
This is the controller:
package com.frankmoley.london.data.webservice;
import com.frankmoley.london.data.entity.Room;
import com.frankmoley.london.data.repository.RoomRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import java.util.ArrayList;
import java.util.List;
#RestController
public class RoomController {
#Autowired
private RoomRepository repository;
#RequestMapping(value="/rooms", method= RequestMethod.GET)
List<Room> findAll(#RequestParam(required=false) String roomNumber){
List<Room> rooms = new ArrayList<>();
if(null==roomNumber){
Iterable<Room> results = this.repository.findAll();
results.forEach(room-> {rooms.add(room);});
}else{
Room room = this.repository.findByNumber(roomNumber);
if(null!=room) {
rooms.add(room);
}
}
return rooms;
}
}

Hibernate: select employee0_.id as id1_0_, employee0_.email as email2_0_, employee0_.name as name3_0_, employee0_.salary as salary4_0_ from employee employee0_
you can clearly see that there aren't any references of RequestMappingHandlerMapping
But still the service is hosted at "/".
I have used the following URL:
http://localhost:8080/employees/springEntityManagerJpa
With other spring application which is not spring boot, the URL is as follows:
http://localhost:8080/spring-rest/api/employees/springEntityManagerJpa
I assume your is the similar case. May be the service is up, but you are providing the wrong endpoints. Just remove the context path. In my case I removed /spring-rest/api
Hope this helps!!!
