Table not found error while starting my spring boot application using JPA and derby database

i am creating a very simple spring boot application. I have a topic class which is an entity and i have written a service called TopicService and using CrudRepository methods to do crud operation. When i am starting my application i am getting below message in my consol.:

The one thing you missed is database connection URL.
Add this to your application.properties file.
spring.datasource.url=jdbc:derby:mydb;create=true

The solution you can apply here is to add the following parameter to the application.properties file.
spring.datasource.initialization-mode=always

spring data RepositoryRestResource not being mapped to endpoints in spring boot app

I've been trying to set up a rest service using spring data rest and spring boot. I followed the tutorial at https://spring.io/guides/gs/accessing-data-rest/ but the expected rest endpoints were not created on startup, and calling get methods on them only led to a 404. I can create an endpoint with RestController, but not with RepositoryRestResource. I am using Spring Boot 2 and hibernate 5.2, with postgres as the backing datastore. I am using eclipse, and have tried running the application via Run Java Application in eclipse, as well as running it from the windows command line using java -jar. The output and end result is the same. Does anybody know what I'm doing wrong and what I need to do for the expected endpoints to be created by the RepositoryRestResource? I've put example code below, with the spring boot output at the bottom, but first here are some similar questions and what I've tried:
this question has an accepted answer which seems to suggest its an entity scanning issue. However, I have added EntityScan to the Application and that didn't seem to help.
RepositoryRestResource with spring-boot CLI
this question has an answer suggesting wrapping the repository in a controller class with RestController instead of using RepositoryRestResource. I can do that, but I don't want to write all the extra code, I would rather that RepositoryRestResource work instead.
Clueless what I'm doing wrong setting up Spring Boot REST app

Spring Boot Kotlin API returns 404 response for all endpoints

I'm using Spring Boot with Kotlin . The rest controller returns 404 error for all endpoints. In the starting logs the endpoints in the controller are not present. Any endpoint returns the same 404 response.
These are the steps I have tried,
Tried clearing cache/target
Moved all classes into single directory
Tried adding ComponentScan annotation but it is not accepted.
I'm using cmd line to run the project
Same output seen when running java -jar $jarfile
Checked annotations Repository , Service , RestController
Controller:

I guess your CricketerController is not in a subpackage relative to your main class. So you basically have two options:
Place your main class directly under the package com.example
Add the annotation at the bottom of this answer to your main class.
Using any of these two methods makes the controller class visible for Spring at startup and therefore should create your mappings.
#ComponentScan(basePackages = { "com.example.controller"} )

Rest Controller not Working

I have initialed spring boot project using start.spring.io and added WEB,JPA,H2 dependencies.

as you can see spring didn't mapped the /hello url

Considering that the other answers don't explain why it doesn't work as expected, here's why.
Spring uses component scanning to find eligible beans (#Repository, #Service, #Component, #Controller, ...). This is usually done by using the #ComponentScan annotation.
This is explained in the core docs:
To autodetect these classes and register the corresponding beans, you need to add #ComponentScan to your #Configuration class, where the basePackages attribute is a common parent package for the two classes. (Alternatively, you can specify a comma/semicolon/space-separated list that includes the parent package of each class.)
Spring Boot, by default only scans components within the same package (and including subpackages) of the main class. This is because the #SpringBootApplication annotation includes a #ComponentScanby default, as mentioned in the Spring boot docs:
The #SpringBootApplication annotation is equivalent to using #Configuration, #EnableAutoConfiguration and #ComponentScan with their default attributes
If you want Spring to automatically detect your controller, you have three options:
Move the controller to the com.example.demo package. This is the recommended approach according to the Spring boot documentation.
Telling Spring to look at the controller package by adding a #ComponentScan annotation:
#SpringBootApplication
#ComponentScan({"com.example.demo", "controller"}) // Add this
public class DemoApplication {
// ...
}
Telling Spring to look at the controller package by configuring the scanBasePackages property of #SpringBootApplication:
#SpringBootApplication(scanBasePackages = {"com.example.demo", "controller"}) // Add this
public class DemoApplication {
// ...
}

Spring reference doc says - Generally recommend that you locate your main application class in a root package above other classes like
com
+- example
+- myproject
+- Application.java
|
+- domain
| +- Customer.java
| +- CustomerRepository.java
|
+- service
| +- CustomerService.java
|
+- web
+- CustomerController.java

why spring boot always shutdown in two hours

i build it using mvn clean package and get a xxx.jar file.
run $java -jar xxx.jar >> output.log & start it, and it works well.
but about two hours later, it shutdown, why?
here is an answer but don't work for me >>https://stackoverflow.com/a/22409655/1767024
here is my output.log:

Run your application as follows instead:
nohup java -jar xxx.jar > output.log 2>&1&
From Wikipedia:
nohup is a POSIX command to ignore the HUP (hangup) signal. The HUP signal is, by convention, the way a terminal warns dependent processes of logout. Output that would normally go to the terminal goes to a file called nohup.out if it has not already been redirected.
From the Linux man pages:
nohup - run a command immune to hangups, with output to a non-tty
Furthermore, if you are only adding the web server to keep your application alive and do not actually use it, consider using a CountDownLatch instead:
#Bean
public CountDownLatch closeLatch() {
return new CountDownLatch(1);
}
public static void main(String... args) throws InterruptedException {
ApplicationContext ctx = SpringApplication.run(MyApp.class, args);
final CountDownLatch closeLatch = ctx.getBean(CountDownLatch.class);
Runtime.getRuntime().addShutdownHook(new Thread() {
#Override
public void run() {
closeLatch.countDown();
}
});
closeLatch.await();
}
Now to stop your application, you can look up the process ID and issue a kill command from the console:
kill <PID>
