SpringBootTest classes attribute not loading configuration class - spring

After updating from Spring Boot 1.4 to 2.1.1, I have an issue which seems to be that my SpringBootTest is no longer loading the test configuration class.
Here are the ways I have tried and the class is not getting loaded. Any package that the config class component scans or any bean created in the config class are not there. I have tried these approaches which worked in Spring Boot 1.4.x but no longer work in 2.1.1:-
#SpringBootTest(classes=TestConfig.class)
or like this
#SpringBootTest
#ContextConfiguration(classes=TestConfig.class)

I got it working with:
#RunWith(SpringRunner.class)
#SpringBootTest(classes = TestConfig.class)

Facing issue while adding Springdoc-openapi in Spring Framework based project (Not Spring Boot)

We have Spring framework (version 5.3.22) based application, not a spring boot.
We have added springdoc-openapi (1.6.11) dependency along with below openapi configuration.
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = {"org.springdoc"})
#Import({org.springdoc.core.SpringDocConfiguration.class,
org.springdoc.webmvc.core.SpringDocWebMvcConfiguration.class,
org.springdoc.webmvc.ui.SwaggerConfig.class,
org.springdoc.core.SwaggerUiConfigProperties.class,
org.springdoc.core.SwaggerUiOAuthProperties.class,
org.springframework.boot.autoconfigure.jackson.JacksonAutoConfiguration.class})
public class OpenApiConfig implements WebMvcConfigurer { }
In our application, we have multiple projects having mixed of Java configurations and XML based configurations.
Both types of classes (java config like #controller/#service and XML definitions like <bean id="".... >) are having dependencies injected through #Autowired.
The classes having beans created through component scanning (#controller/#service) are working well, all the injected dependecies are resolved as expected.
But the classes having XML definitions are having issues, where dependencies injected through setter and bean ref are working fine, but the dependencies injected through #Autowired are found as null at runtime. Looks like #Autowired annotation itself is not getting resolved while creating bean of such classes. We have also verified that our XML context file has <context:annotation-config /> defined and so #Autowired should get resolved here.
Without this springdoc-openpi dependency and these OpenApiConfig, we are not facing this issue.
Does anyone have more insights here ?

Spring boot Jpa is not working with Spring batch and spring integration

I am working with spring batch. I needed to add some jpa repositories. So previously i was using JDBCTemplate which was working fine.
But when I started working with JPA, the spring boot application could not find the repos. Which were there.
#Autowired
ClassLevelConfigRepo clcr;
I checked these things as the best practices.
Added #EnableJpaRepositories in springBoot application class.
Added #Repostiories to the repository interfaces.
extended the interfaces with JpaRepository<Account, String>
Added #Entity to the entity classes and defined the #Table and # Column annotations properly.
But I am still getting below error.
Field clcr in com.cloudtask.batchconfig.util.LhmUtility required a bean of type 'com.cloudtask.batchconfig.repo.ClassLevelConfigRepo' that could not be found.
I tried checking all the dependencies in pom.xml it was as per recommended. And I have all the tables defined properly in data base.
I was expecting the application to return the Autowired clcr object propely.
Edit 1 : spring boot application annotations
#SpringBootApplication
#ComponentScan({"com.cloudtask"})
#EnableAsync
#IntegrationComponentScan({"com.cloudtask"})
#EnableIntegrationManagement(defaultLoggingEnabled = "true")
#EnableJpaRepositories
#EntityScan
public class imclassApplication ```
When you work with Spring Data Jpa with those basic points you should also keep track of below points.
you have added spring-boot-starter-data-jpa in your pom.xml
you have added the entity and repo package below one level of the application package.
If you the package is at same level you should specify the exact package details in the annotation. in your case it should be like :
#EnableJpaRepositories("com.cloudtask.batchconfig.repo")
#EntityScan(basePackages = {"com.cloudtask.batchconfig.entity"})
Happy programming!

Cucumber and Spring boot integration

I have a microservice application developed using spring boot and used cucumber to test. I have a separate project folder "bdd" where I stored all my features files and the step defns and this project is not deployed in the war file.
I have a requirement where I need to hit the DAO class's methods directly for some testing and I found that from BDD folder, I don't have the access to get the instance of the beans from spring boot.
Found some articles as well on how to integrate the cucumber and the spring boot using the #RunWith(SpringRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) annotations. however It seems not to be working for me.
Does anyone have experience any such requirements or could anyone suggest me on what should be the correct approach.
Thanks.
Edited :
I am trying to use an instance of a bean which was initialized already as part of the spring container. when I tried to #Autowire or #Inject using:here registry is the bean instance I am trying to use.
#RunWith(SpringRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
#Component
public class AbstractDefs {
#Autowired
private static ConnectionProviderRegistry registry;
dao = new MyDaoClass(registry);
the variable registry is still null.

spring boot #autowired filed injected with null in the #configuration class but worked with #import

According to the reference using-boot-configuration-classes, I used #ComponentScan on the Application class and use the #Configuration on my config class, in my config class, I want to inject beans defined in other config class by using #Autowired annotation, but when I run the application, I got null for these fields, I tried to use import on the application and remove the #Configuration from config class, everything works fine.
Is it a bug of spring boot or I am misunderstanding about the usage of #Configuration annotation?
Are you trying to autowire other configuration classes into Application class?
Use a fresh method along with #PostConstruct to make it call automatically after Spring creates an instance of Application class.

Spring-Boot module based integration testing

I have a multi-module Spring-Boot project.
I was wondering how I can set up integration testing just to test Spring Data JPA repositories? The following approach fails with this exception:
HV000183: Unable to load 'javax.el.ExpressionFactory'. Check that you have the EL dependencies on the classpath.
Since this module does not depend on the web module, there is no web application that can be started.
#RunWith(SpringJUnit4ClassRunner.class)
#IntegrationTest
#SpringApplicationConfiguration(classes = TestConfiguration.class)
class CardInfoRepositoryIT {
#Autowired CardInfoRepository cardInfoRepository;
#Test
void testLoadData() {
assert cardInfoRepository.findAll().size() == 1
}
}
As Marten mentioned, #IntegrationTest should only be used when you need to test against the deployed Spring Boot application (e.g., deployed in an embedded Tomcat, Jetty, or Undertow container). So if your goal is to test your repository layer in isolation, you should not use #IntegrationTest.
On the other hand, if your tests require specific Spring Boot functionality (in contrast to standard Spring Framework functionality, semantics, and defaults), then you will in fact want to annotate your test class with #SpringApplicationConfiguration instead of #ContextConfiguration. The reason is that #SpringApplicationConfiguration preconfigures the SpringApplicationContextLoader which is specific to Spring Boot.
Furthermore, if you want your repository layer integration tests to run faster (i.e., without the full overhead of Spring Boot), you may choose to exclude configuration classes annotated with #EnableAutoConfiguration since that will auto-configure every candidate for auto-configuration found in the classpath. So, for example, if you just want to have Spring Boot auto-configure an embedded database and Spring Data JPA (with Hibernate as the JPA provider) along with entity scanning, you could compose your test configuration something like this:
#Configuration
#EnableJpaRepositories(basePackageClasses = UserRepository.class)
#EntityScan(basePackageClasses = User.class)
#Import({ DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class })
public class TestRepositoryConfig {}
And then use that configuration in your test class like this:
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = TestRepositoryConfig.class)
#Transactional
public class UserRepositoryTests { /* ... */ }
Regards,
Sam
p.s. You might find my answer to the following, related question useful as well: Disable security for unit tests with spring boot
I resolved this by having the following test config class.
#Configuration
#EnableAutoConfiguration
#ComponentScan
#PropertySource("classpath:core.properties")
class TestConfiguration {
}
core.properties is also used by the main application and it contains datasource information. #IntegrationTest annotation can be removed on the test class.
I also added the following to the module as dependencies:
testRuntime 'javax.el:javax.el-api:2.2.4'
testRuntime 'org.glassfish.web:javax.el:2.2.4'
