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:

I remove server.address=localhost from application.properties and it works well.
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
private static final Logger LOGGER = LoggerFactory.getLogger(WebsocketBrokerConfig.class);
#Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
//for subscribe prefix
registry.enableSimpleBroker("/user");
//for publish prefix
registry.setApplicationDestinationPrefixes("/app");
//user destination provides ability to have unique user queue
//registry.setUserDestinationPrefix("/user");
}
#Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/broadcast")
.setAllowedOrigins("http://ec2....amazonaws.com")
.withSockJS()
.setHeartbeatTime(60_000);

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/
I have packaged my spring boot rest backend with mvn package.
When I run the jar on the server with java -jar ... the application starts and gets killed after a few seconds.
I also see that on the linux top view, that the java process goes over 300% CPU. Is that maybe the reason the process gets killed? And if yes, what can I do?
My spring boot application is not very big. Actually its almost empty.

Some ideas to check:
Try to run as detached: java -jar yourapp.jar &
Try ( just once ) to run under root
Check logs: journalctl -ex for details of who exactly has killed your application.
Depends on results, can plan next steps - typically which settings to adjust.
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" }
}

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.

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;
}
}
Entity:
package com.frankmoley.london.data.entity;
import javax.persistence.*;
#Entity
#Table(name = "ROOM")
public class Room {
#Id
#Column(name = "ROOM_ID")
#GeneratedValue(strategy = GenerationType.AUTO)

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!!!
