I am using spring-boot-starter-web latest version 2.2.6.RELEASE. But my application always returns null for a variable with #value annotation.

Always getting null when I starting the server,
dataprocEndpoint: null
What configuration am I missing here?
Kindly provide your inputs here.
surround your property in quotes:
dataproc:
host: 'dataproc.googleapis.com:443'
Yml processor interprets your config property name as dataproc.host.dataproc.googleapis.com.443
Remove static from your field declaration.
#Value("${dataproc.host}")
private String dataprocEndpoint;
Static fields are initialized with class load. Spring bean post processors can’t inject values at so early phase. You can use setter injection if you want to inject value to static field anyway.

There is surprising situation, which I can't understand. I have test automation with RestAssured (pet project). I want to prepare RequestSpecification spec variable in #BeforeSuite method, in parent class. Then I want to use spec variable in tests of child class. Here is code of parent class
public class BaseTest {
private String baseUrl = "https://api.thecatapi.com/v1/";
protected RequestSpecification spec;
#BeforeSuite
public void beforeSuite() {
String apiKey = System.getProperty("api_key");
spec = new RequestSpecBuilder()
.setContentType(ContentType.JSON)
.setBaseUri(baseUrl)
.addHeader("x-api-key", apiKey)
.addFilter(new ResponseLoggingFilter())
.addFilter(new RequestLoggingFilter())
.addFilter(new AllureRestAssured())
.build();
}
}
And here is a test in child class'
public class OurLittleTest extends BaseTest {
#Test
public void test() {
//1
String id = Breeds.search(spec, "Scottish Fold").then().extract().body().jsonPath().get("[0].id");
problem is that spec variable in test is null, while I was waiting it won't be null...
Why it happens? Why spec is null ?
I've recordered a screencast where you can see my problem
UPDATE
Everything is fine with Junit 5. The spec variable is not null in child classes anymore. So here are me build.gradle files:
With TestNG:

}
if (project.hasProperty("api_key")) {
systemProperties.put("api_key", "$api_key")
}
}
With Junit 5:
plugins {
id 'io.qameta.allure' version '2.5'
id 'java'
}
allure {
configuration = 'testImplementation'
version = '2.7.0'
useJUnit5 {
version = '2.7.0'
}
}
sourceCompatibility = JavaVersion.VERSION_1_8
group 'org.example'

repositories {

mavenCentral()
}
dependencies {
implementation group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: '2.9.5'

}
test {
useJUnitPlatform{
systemProperty 'junit.jupiter.testinstance.lifecycle.default' , 'per_class'
systemProperty 'junit.jupiter.execution.parallel.enabled', 'true'
systemProperty 'junit.jupiter.execution.parallel.mode.default', 'same_thread'
systemProperty 'junit.jupiter.execution.parallel.mode.classes.default', 'concurrent'
}
if (project.hasProperty("api_key")) {
systemProperties.put("api_key", "$api_key")
}
}
What's wrong with TestNG ?
The problem is usage of #BeforeSuite. It is meant to be used only once per suite and ignored in following runs.
For initializing the spec you can either do it directly inline in the field like protected RequestSpecification spec = new RequestSpecBuilder()... or use #BeforeClass.
I tested your code, no error. The problem might be in OurLittleTest class you use Junit, and you use testNG in BaseTest class
In my spring boot application I have below code which has AnnotationConfigWebApplicationContext and i included FrameworkWebconfig class (from jar file) in that AnnotationConfigWebApplicationContext which is used for escaping special charaters in JSON response. But for some issues I had to remove that framework web config class and after that special charaters were not escaping in JSON response (as expected, in TEST environment). Same code when i run in PROD its not working it is still escaping those special characters. This application is deployed on Weblogic servers. I am not getting whats the issue here. Can someone please help me understand why this is happening?
#Configuration
public class Application implements WebApplicationInitializer {
....
private AnnotationConfigWebApplicationContext getContext() {
logger.info("Entering method : getContext");
AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
context.register(FrameworkPropertySourcesConfig.class);
//context.register(FrameworkWebConfig.class); //this line, after removing its working in TEST but not in prod
context.register(AppConfig.class);
logger.info("Exiting method : getContext");
return context;
}
.....
}
#EnableWebMvc
#Configuration
public class FrameworkWebConfig extends WebMvcConfigurerAdapter {

After download dependencies and add in models annotations like #Entity, #Table #Id and etc. i have an error: cannot find symbol
#Entity
^
symbol: class Entity
But i have spring-boot-starter-jpa in dependencies, i don't know why in module i can't use dependencies.
With dependencyManagement you only manage dependencies like version, overrides etc. you don't actually add dependencies to a project. For that use dependencies like you use in the other places.

I am facing issue of NullPointer on this line def generator = new DefaultGenerator().opts(clientOptInput).
Update-1
I understand the question seems fairly easy for NullPointer exception in java. but trust me, I am not able to figure out in build.gradle why it is failing as it is not even showing proper error message that what is missing. Below shown message is all I am getting. Even the debugging of groovy script isn't helping me.
Execution failed for task ':generateServer'.
> java.lang.NullPointerException (no error message)
Update-2
I just got to see in the DefaultGenerator.java on line number 77, found this line.
This is where I am getting NullPointerException this.config.additionalProperties().putAll(opts.getOpts().getProperties());
I am not sure what is missing in parameters. I am passing opts and getOpts() is also populating properties file.
Using gradle version 4.9.
Okay I figured it out, it was a silly mistake in understanding and in code as well.
I got to know this mistake just after debugging and browsing through the swagger-codegen code. I realized that the config is required to generate code, based on this config specified it is generating code. I was generating the spring based CodeGenConfiguration but I was not passing it into the clientOptInput. My understanding was wrong, I assumed it will load the class for CodeGenConfig (Which it does load) and that's it. however you also need to pass it to the clientOptInput variable.
def codeGenConfig = CodegenConfigLoader.forName('spring')
clientOptInput.setConfig(codeGenConfig)
Since, the code for DefaultGenerator.java as per below:
#Override
public Generator opts(ClientOptInput opts) {
this.opts = opts;
this.openAPI = opts.getOpenAPI();
this.config = opts.getConfig();
I need to set it to the ClientOptInput instance. This is the reason. Posting for others like me who makes mistakes :) :)
I've a Spring Boot Application with main class:
#SpringBootApplication
public class MyApplication extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(MyApplication .class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application){
return application.sources(applicationClass);
}
private static Class<MyApplication > applicationClass = MyApplication .class;
}

When I try to deploy the war file on WebSphere Application Server 9.0 Traditional, it starts but takes very long time. Without war file, server starts and stops very normally, but with application, server hangs.
Am I missing something?
Thank you for help!!
The startup delay is probably caused by CDI's implicit bean archive scanning. If you are not using CDI, you can disable implicit bean archives with com.ibm.ws.cdi.enableImplicitBeanArchives=false.
You can find a much more detailed explanation in this tech note:
