Hi I have springboot running in linux server connecting to RDS oracle and its getting stopped after two hours for the below reason and we couldnt find out exact reason for the same:

Here is the code I wrote:
#GetMapping("/tweet2")
public ModelAndView getTweetsByEmail(#RequestParam String email) {
ModelAndView modelAndView = new ModelAndView("tweets");
List<Tweet> tweets = tweetMap.get(email);
modelAndView.getModel().put("tweets",tweets);
return modelAndView;
}
And there is a tweets.mustache file under the resources folder. Not sure why its unable to detect it
I'm using S3 as a backend for Spring Config server. I uploaded 3 files in the my bucket.
application-local.properties
application-prod.properties
application-qa.properties
Then I am trying to hit REST API endpoint as mentioned in the documentation.
URL: http://localhost:4000/application/qa
After 9 seconds I get a 200 response, below is the body.
"name": "application",
"profiles": [
"qa"
],
"label": null,
"version": null,
"state": null,
"propertySources": []
}
Technically I should get data in propertySources but I'm not getting anything.

I'm not sure how to resolve this issue.
A couple things that might help. If you are on a version of Spring Boot >= 2.4, the property spring.cloud.config.server.bootstrap=true needs to be supplied as a command-line argument or via the maven starter here. That property has to be read before the "bootstrap" phase before application.properties|yml is read.
It could be related to the following:
IAM access to the selected buckets
Credentials - I have only used the provider chain for authenticating against AWS S3 when using Config Server. Looking at the source code, it seems like the provider chain is the only way to create the S3 client. Shame that you can't configure your own AmazonS3 bean.
The response you're getting indicates that the app can talk to S3, but it cannot find the properties. Spring Config Server will report DOWN when hitting /actuator/health if it cannot communicate with S3. Does your app show as healthy in actuator?
I'm using okhttp with ktor on my server application and run like this.
runBlocking {
launch {
okhttpClient.get(url)
}
}
and this is logging result.

It's started tomcat nio thread and running on okhttp thread.
you know coroutine is light thread. I expect that runBlocking code working on coroutine thread.
but it seem another thread.
So okhttpClent run on coroutine thread? or normal thread?
What should I do to work with coroutine thread?
Using CIO client?
Thanks all.
This is CIO calling log. It looks like working coroutine thread

Even though most people see coroutines as lightweight threads they are in fact not really that. A coroutine starts in a thread and then suspends until its ready to resume. See: Coroutines basics:
...a coroutine is not bound to any particular thread. It may suspend its execution in one thread and resume in another one.
Coroutines are not designed to stick to one thread and only use that. You'll need to clarify the use case you need this for as it could be more of a code design decision.
This is a Spring Boot project.
I have added Spring Fox a Swagger 2 based API documentation tool to my .pom file and I have
configured it but for some reason (my guess is the resource mapping is not working properly)
The basic part of the confguration is there but when I have added more specific configuration,
like my contact or description of the API -> this part is not showing.
This is my Swagger configuration class:
#Component
#PropertySource("classpath:springFoxdocumentation.yml")
#EnableSwagger2
#EnableWebMvc
public class SpringFoxConfig implements WebMvcConfigurer {
#Value("${api.common.version}")
private static String apiVersion;
#Value("${api.common.title}")
private static String apiTitle;
#Value("${api.common.description}")
private static String apiDescription;
#Value("${api.common.termsOfServiceUrl}")
private static String apiTermsOfServiceUrl;
#Value("${api.common.license}")
private static String apiLicense;
#Value("${api.common.licenseUrl}")
private static String apiLicenseUrl;
#Value("${api.common.contact.name}")
private static String apiContactName;
#Value("${api.common.contact.url}")
private static String apiContactUrl;
#Value("${api.common.contact.email}")
private static String apiContactEmail;
#Bean
public Docket apiDocumentation(){
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())
.build()
.globalResponseMessage(RequestMethod.GET, Collections.emptyList())
.apiInfo(new ApiInfo(
apiVersion,
apiTitle,
apiDescription,
apiTermsOfServiceUrl,
new Contact( apiContactName, apiContactUrl,apiContactEmail),
apiLicense,
apiLicenseUrl,
Collections.emptyList()
));
}
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}
}
I know that I shouldn't have there the resource handler method, but since I have assumed that this problem is caused by resource mapper I have added it int the code (but it didn't help)
And this is my .yml file under resources folder
api:
common:

There are two issues in your code. First of all, #Value does not work on static fields. So all your springfox declared fields are null. Spring never set values in them.
If you remove the static from your fields , Spring will tell you that it doesn't find the properties like api.common.version or api.common.title. Because #PropertySource does not load yml files. It is declared in official documentation.
But there are workaround, you can follow this source here to use yml files with #PropertySource.
Upgrading Spring Boot 2.1.x from 2.0.x, not logging MVC mapping logs..
Spring Boot 2.0.x logs MVC Mapping at INFO level, it was very convinient and easily identifiable logs.
**Spring Boot 2.0.x**
2019-01-24 20:10:11.165 INFO [ main] s.w.s.m.m.a.RequestMappingHandlerMapping Mapped "{[/mapping2],methods=[GET]}" onto public java.lang.String com.test.controller.ControllerClass.method2()

As per Spring Boot 2.1.x documentation,
https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.1-Release-Notes#logging-refinements
There are no Info logs for MVC Mapping. Only summary logged as debug log.
We have to update level to TRACE to get more details.
**Spring Boot 2.0.x**

By updating web log level to DEBUG or TRACE, We get more debug logs from Spring Web and they are not useful always. Unless, TRACE level, they are not much meaningful.

Is it possible to get Spring log information ? and How ?
From Spring Boot 2.1 version to get RequestMappingHandlerMapping log on console try add
logging.level.org.springframework.web=trace
on application.properties file
It worked for me
