Spring Boot Configuration Bean behaves different at Windows and Linux - spring

I am using openjdk14 and have interesting problem here. I have reactive project and use spring security and spring session modules. I have created my WebSessionManager as described here. (https://docs.spring.io/spring-session/docs/current/reference/html5/#websession-how)
#Configuration(proxyBeanMethods = false)
#Slf4j
public class SpringWebSessionConfiguration {
#Autowired(required = false)
private WebSessionIdResolver webSessionIdResolver;
#Autowired
private ConfigurableApplicationContext context;
#Bean(WebHttpHandlerBuilder.WEB_SESSION_MANAGER_BEAN_NAME)
public WebSessionManager webSessionManager(ReactiveSessionRepository<? extends Session> repository) {
log.info("line 1");
...
return manager;
}
}
Problem
When I try to compile and run in my local computer (windows 10), my bean is created successfully and I see "line 1" log, so everything is fine. But when i try to compile and run in linux (centos 8) instead, my bean is not created so i cannot see "line 1" log.
Here is the windows log
2020-12-08 17:36:51.371 DEBUG 8368 --- [ main]

Linux and Windows are picking different configuration as you can see in logs. Has anyone encountered a similar error before ? It think it must be bug on java. How can I report this? Would you try same configuration if possible to be sure?

Spring Boot: Could not resolve matching constructor when using scope: prototype

Problem
I'm having an issue where, any bean I define with the scope = prototype causes a BeanCreationException:
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myClass' defined in class path resource [application-context.xml]: Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to avoid type ambiguities)

Example
This is the most basic example I could create that reproduced the problem...
MyClass.java:
Variation 1
public class MyClass {
public String doNothing() {
return "Do nothing";
}
}
Variation 2
public class MyClass {
public MyClass() {}
public String doNothing() {
return "Do nothing";
}
}
application-context.xml
<bean id="myClass"
class="com.example.coaching.models.MyClass"
scope="prototype">
</bean>
MyApp.kt
class MyApp
fun main() {
val context = ClassPathXmlApplicationContext("beanScope-applicationContext.xml")
val myClass = context.getBean("myClass", MyClass::class) as MyClass
println(myClass.doNothing())
}
Other Info
I experienced this in a more complex project, but made this one to try to narrow down the problem and expected I would find something, but I have no clue.
If I change the scope to singleton, it works fine.
Happens with xml configuration as well as annotations
Tried creating MyClass in both Kotlin and Java
Here's my pom.xml just in case

Repository bean cannot be found (No idea why)

I'm trying to run my application and I'm receiving this error:
***************************
APPLICATION FAILED TO START
***************************
Description:
Parameter 0 of constructor in com.danielturato.product.services.ProductServiceImpl required
a bean of type 'com.danielturato.product.persistence.ProductRepository' that could not be
found.
Action:
Consider defining a bean of type 'com.danielturato.product.persistence.ProductRepository' in
your configuration.
I have no idea why this is occurring. I've tried to look at past solutions where its said to use the #EnableMongoRepository to point to the correct package however I have tried this and it doesn't work. I've also tried adding the #Repository annotation above my repository (even though its not needed) and it doesn't work still. Here is my code for my repository, application & where the repository is failing to be injected.
Application:
#SpringBootApplication
#ComponentScan("com.danielturato")
public class ProductServiceApplication {
private static final Logger LOG = LoggerFactory.getLogger(ProductServiceApplication.class);
public static void main(String[] args) {
SpringApplication.run(ProductServiceApplication.class, args);
}
}
Repository:
public interface ProductRepository extends ReactiveCrudRepository<ProductEntity, String> {
Mono<ProductEntity> findByProductId(int productId);
}
ProductServiceImpl:
#RestController
public class ProductServiceImpl implements ProductService {
private static final Logger LOG = LoggerFactory.getLogger(ProductServiceImpl.class);
private final ServiceUtil serviceUtil;
private final ProductRepository repository;
private final ProductMapper mapper;
#Autowired
public ProductServiceImpl(ProductRepository repository, ProductMapper mapper, ServiceUtil serviceUtil) {
this.repository = repository;
this.mapper = mapper;
this.serviceUtil = serviceUtil;

If anyone can suggest for me anything to try or would like me to put more info here please let me know.
The stack trace you have included in your question does point to the ProductRepository not being available for autowiring and as a previous comment has pointed out this is because you are missing the #Repository annotation from your repository.
Another reason is if your repository cannot find a matching entity. This might be for example if the Id is the wrong type or is missing the #Id annotation, if the entity doesn't have either #Entity/#Document or if it is missing an all args constructor. Plus in your case you have added a findByProductId() method so your entity will need a productId field too.
I would also remove the #ComponentScan annoatation from your application class as this is included by default in #SpringBootApplication unless you are intentionally pointing it at a different class path.
If this still fails as you have mentioned in your comments is it failing for the same reason or is there a different error now related to ProductMapper or ServiceUtil?

NotFound Failure in Spring Integration Test of Health Indicator

I want to write a simple test for a custom HealthIndicator, which is defined in its own module separated from the module of the Spring application.
The HealthIndicator is pretty simple:
#Component
public class MyHealthIndicator implements HealthIndicator {
public Health health() {
return Health.up().withDetail("my-health", "okay").build();
}
}
This is the test:
#WebAppConfiguration
#ContextConfiguration(classes = {TestConfiguration.class, MyHealthIndicator.class})
#ExtendWith(SpringExtension.class)
class MyHealthIndicatorTests {
#Autowired
private MockMvc mockMvc;
#Test
public void healthTest() throws Exception {
mockMvc.perform(get("/management/health")).andExpect(status().isOk());
}
}
And this is the simple Test Configuration:
#Configuration
#EnableWebMvc
#ImportAutoConfiguration(classes = {HealthEndpointAutoConfiguration.class, MockMvcAutoConfiguration.class})
#TestPropertySource(properties = {"debug:true", "management.endpoints.enabled-by-default:true",
"management.endpoints.web.base-path:/management", "management.endpoints.web.exposure.include=health"})
public class TestConfiguration {
}
The test of the health endpoint returns a 404 - Not Found.
In the logs I see that the TestDispatcherServlet has no mapping for the health endpoint:
12:48:38.309 [main] WARN org.springframework.web.servlet.PageNotFound - No mapping for GET /management/health
but why?
In the logs I see also that the HealthEndpoint actually is created:
12:48:38.013 [main] DEBUG org.springframework.beans.factory.support.DefaultListableBeanFactory - Creating shared instance of singleton bean 'healthEndpoint'
But the mapping in the TestDispatcherServlet seems not to be configured. How can I enable the mapping?
Please note: I want to test my Health Indicator without a SpringBootApplication. Isn't that possible at all?
Edit:
Nothing special in the POM:

Looks like a typo in defining the test property source.
Instead of
management.endpoints.web.base-path:/management
management.endpoints.enabled-by-default:true
it should be
management.endpoints.web.base-path=/management
management.endpoints.enabled-by-default=true

spring boot #repository bean from Maven dependency not found

I'm working on multiple Spring Boot projects using spring-data-mongoDB (w/o JPA). One that contains the common (udc-common) components, repositories and services and others (eg udc-gateway) that use these components. the udc-common library is declared as a maven dependency in the other projects.
(you'll find enclosed the maven detailed configurations at the end of this post)
Environment structure
udc_common project
udc_common.models
udc_common.repositories
udc_common.services
udc_common.interfaces
udc_gateway project
udc_gateway.controllers
udc_gateway ....
gatewayApplication.java
gateway pom.xml
<dependency>
<groupId>org.open_si</groupId>
<artifactId>udc-common</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
in the udc-gateway project I have a rest controller thats refers to a udc-comm SampleService. When running it I face an error
Parameter 0 of constructor in org.open_si.udc_common.services.SampleService required a bean of type 'org.open_si.udc_common.repositories.SampleRepository' that could not be found.
the coding organization is :
the controller (SamplesController) belongs to the gateway project
the service (SampleService) and its repository (SampleRepository) belong to the common project being declared as maven dependency in the gateway project
Obviously the SampleService injection does work but its SampleRepository dependency doesn't. As the common package is an external one I've set the #componentscan accordingly in the gateway app main class
tryed
#ComponentScan("org.open_si.udc_common")
and
#ComponentScan({
"org.open_si.udc_common.repositories",
"org.open_si.udc_common.services"
})
the SamplesController (gateway project) code excerpt related for the SampleService is
#RestController
#RequestMapping("/samples")
public class SamplesController {
#Autowired
private SampleService service;
......
the SampleService (common project) is
#Service
#EnableMongoRepositories
public class SampleService {
#Autowired
private SampleRepository sr;
void insert(BaseSampleEntity sample) {
this.sr.insert(sample);
}
public void delete(BaseSampleEntity sample) {
this.sr.delete(sample);
}
.....
or also tryed
#Service
#EnableMongoRepositories
public class SampleService {
private final SampleRepository sr;
public SampleService(SampleRepository repository) {
sr = repository;
}
void insert(BaseSampleEntity sample) {
this.sr.insert(sample);
}
public void delete(BaseSampleEntity sample) {
this.sr.delete(sample);
}
and the SampleRepository (common project) is
// #Repository (JPA only)
public interface SampleRepository extends MongoRepository<BaseSampleEntity, String> {
List<BaseSampleEntity> findByNodeUuid(String Uuid, Sort sort, Pageable pageable);
List<BaseSampleEntity> findByFieldUuid(String Uuid, Sort sort, Pageable pageable);
so the raised exception
Parameter 0 of constructor in org.open_si.udc_common.services.SampleService required a bean of type 'org.open_si.udc_common.repositories.SampleRepository' that could not be found.
leads me thinking that something is wrong in the spring boot IOC process. Any idea ?
thanks in advance for your help.

Try adding below annotation in the spring boot main application class (ie. class annotated with SpringBootApplication - GateWayApplication.java)
#EnableMongoRepositories(basePackages = "org.open_si.udc_common")
#ComponentScan("org.open_si.udc_common.services")
#EntityScan(basePackages ="org.open_si.udc_common.models")
Also, as you mentioned you don't need to annotate repository class with #Repository as this is already managed by spring data
UPDATE:
#SpringBootApplication itself has ComponentScan annoation embedded to it, so it automatically scans all the classes under all the subdirectories.
Hope you have the directory structure somewhat similar to
com.example
--controllers
-- SamplesController
--service
-- SampleService
SampleApplication (this is the class that contains #SpringBootApplication & #EnableMongoRepositories)
Mb you need to add the Spring Data dependency to Maven
As suggested by Kumar V adding
#ComponentScan("org.open_si.udc_common.services")
#EnableMongoRepositories(basePackages = {"org.open_si.udc_common.repositories"})
In the gateway.application.java did the trick.
Unfortunately due to the org.open_si.udc_common.services import, I faced a new issue :
when sending a request against the SamplesController I get an HTTP 404 error.
When removing the ComponentScan of udc-common-services (and the reference to the SampleService in the controller) everythink is ok.
Springs does make some stuff under the wood that I don't understand.

Spring is telling you the problem
org.springframework.hateoas.config.HateoasConfiguration required a single bean,
but 15 were found:
Which means that there are 15 methods that return a bean that fits HateoasConfiguration.
Who are those bastards?
Spring continues right after with the list:
- modelBuilderPluginRegistry: defined in null
- modelPropertyBuilderPluginRegistry: defined in null
- typeNameProviderPluginRegistry: defined in null
- documentationPluginRegistry: defined in null
- apiListingBuilderPluginRegistry: defined in null
- operationBuilderPluginRegistry: defined in null
- parameterBuilderPluginRegistry: defined in null
- expandedParameterBuilderPluginRegistry: defined in null
- resourceGroupingStrategyRegistry: defined in null
- operationModelsProviderPluginRegistry: defined in null
- defaultsProviderPluginRegistry: defined in null
- pathDecoratorRegistry: defined in null
- relProviderPluginRegistry: defined by method 'relProviderPluginRegistry'
in class path resource
[org/springframework/hateoas/config/HateoasConfiguration.class]
- linkDiscovererRegistry: defined in null
- entityLinksPluginRegistry: defined by method 'entityLinksPluginRegistry'
in class path resource
[org/springframework/hateoas/config/WebMvcEntityLinksConfiguration.class]
The list might be not so clear or familiar as it might be that some of these methods are defined by the framework.
So what can be done?
Spring is suggesting a solution:
Action:
Consider marking one of the beans as #Primary,
updating the consumer to accept multiple beans,
or using #Qualifier to identify the bean that should be consumed
Does it mean that I need to reconfigure my #Beans?
Not necessarily. First try to see if someone else faced the same problem.
You may find the solution there.
