Spring Boot Batch application failing to start in a particular environment because of environment property

I ran the batch application in couple of linux environment. The application was working in one of the environment and is failing in other environment. I am getting the below failure message in that environment. The environment had some parameters which is blocking the application to start it seems. What needs to be done to change this and make the application work.
I checked the property file and found this parameter
'ENV=int'.
I think this might be the once causing the issue.

APPLICATION FAILED TO START
Description:
Failed to bind properties under 'env' to org.springframework.core.env.Environment:
Property: env
Value: int
Origin: "ENV" from property source "systemEnvironment"
Reason: org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [org.springframework.core.env.Environment]
Action:
Update your application's configuration.
I have added the code block where the stack trace was pointing the issue.
#Configuration
#EnableConfigurationProperties
#ConfigurationProperties
#PropertySource(value = "file:${PROPS_FILE:cnfg/BtchDb.properties}")
#Component
public class CnfgReader {
#Autowired
private Environment envt;
public Environment getEnvt() {
return envt;
}
public void setEnvt(Environment envt) {
this.envt = envt;
}
}
What changes I have to make in order to make the batch application run in the environment. Thanks in advance.

Spring Boot 1.5.2 - Cannot find Bean due to " Cannot search for matching files underneath URL "?

I'm using Spring Boot 1.5.2 and it has this annoying error which I could not understand the reason.
I have a Main class with these scanning configured:
#EnableJpaRepositories(basePackages = {"com.abc", "org.abc"})
#EntityScan(basePackages = {"com.abc", "org.abc", "abc"})
#ComponentScan(basePackages = {"com.abc", "org.abc", "abc"})
public class ApplicationMain extends SpringBootServletInitializer {
....
}
A model class
File: AbcUser.java
package com.abc.admin.model
#Entity
#Table(name = AbcUser.TABLE_NAME)
public class AbcUser {
}
And an interface class which extends CrudRepository:
File UserRespository.java inside this package.
package com.abc.repository.interfaces
#Repository
public interface UserRespository extends CrudRepository<AbcUser, Long> {
#Transactional
Long deleteByUsername(String username);
}
Now, when I tried to start the web application, it first has the warning which says, it cannot scand files...And then throws error, that the Bean cannot be found.
java -jar abc.war
WARN: Cannot search for matching files underneath URL [war:file:/home//tmp/build/applications/petascope/petascope_main/target/abc.war*/WEB-INF/classes/org/abc/] because it does not correspond to a directory in the file system

Enabling/Disabling database connection on the basis of active profile or yml property value

I want my application to stop loading the database connection when launched in local environment and use Couchbase database when launched in Dev environment. So to start with it I have excluded CouchbaseDataAutoConfiguration -
#SpringBootApplication(exclude= {CouchbaseDataAutoConfiguration.class})
#EnableAspectJAutoProxy()
public class ABCAdapterApplication {
public static void main(String[] args) {
SpringApplication.run(ABCAdapterApplication.class, args);
}
}
And commented out the #Configuration from the AbstractCouchbaseConfiguration class
//#Configuration
public class ABCAdapterBucketConnection extends AbstractCouchbaseConfiguration{
/* buckets configuration here*/
}
After this I can see in the logs that Spring is not loading any database connection but it gives org.springframework.beans.factory.UnsatisfiedDependencyException -
{"timestamp":"2020-05-09 15:31:37.073","severity":"WARN","class":"org.springframework.boot.web.servlet.context.AnnotationConfigServletWebServerApplicationContext","crId":"","msg":"Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'ABCAdapterRetrySourceRoute': Unsatisfied dependency expressed through field 'dataProcessor'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'persistDataProcessor': Unsatisfied dependency expressed through field 'repo'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.vu.payments.abc.adapter.repositories.KafkaPayloadRepository' available: expected at least 1 bean which qualifies as autowire candidate.}
Why the classes with #Repository annotation were not registered in Spring context when I had disabled couchbase auto-configuration ? How can I stop this application from failing to start-up even if there is no database connection when launched in local environment ?

There is a handler class which based on active profile instantiates a data loader class (FromFile or FromDatabase both implementing ConfigLoader i/f). When no profile is selected FromFile gets instantiated and this class makes no reference to any repository class or method that's why It should work even if database has not been loaded. I looked thoroughly and found that KafkaPayloadRepository is being referred directly in PersistDataProcessor. Direct reference to repository classes has to be avoided in this use case and ConfigLoader interface should be used instead.

Spring WebMVC with Data and Couchbase - Error creating bean when trying to inject as service

I just started to work with Spring. I followd some tutorials to create a Spring Web MVC project which works. It is a simple project which displays some information as website using thymeleaf.
Now I wanted to add a couchbase database for storing data, I already worked with couchbase for simple .Net Apps. So I followed the tutorial on the official couchbase blog to create a service for the connection to couchbase. Couchbase with Spring-Boot and Spring Data
But when I try to autowire the service I get the following error message:
[main] INFO org.springframework.web.servlet.DispatcherServlet - Initializing Servlet 'dispatcher'
[main] INFO org.springframework.data.repository.config.RepositoryConfigurationDelegate - Multiple Spring Data modules found, entering strict repository configuration mode!
[main] INFO org.springframework.data.repository.config.RepositoryConfigurationDelegate - Bootstrapping Spring Data repositories in DEFAULT mode.
[main] INFO org.springframework.data.repository.config.RepositoryConfigurationDelegate - Finished Spring Data repository scanning in 70ms. Found 1 repository interfaces.
[main] WARN org.springframework.web.context.support.AnnotationConfigWebApplicationContext - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'indexController': Unsatisfied dependency expressed through field 'buildingService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.xplorg.model.BuildingService' available: expected at least 1 bean which qualifies as autowire candidate.

Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
As far as I understand the message, found Spring the repository but it does not qualify as autowire candidate.
My WebConfig:
#Configuration
#EnableWebMvc
#ComponentScan("com.project.controller")
#ComponentScan("com.xplorg.model")
#EnableCouchbaseRepositories(basePackages = {"com.project.model"})
public class MvcWebConfig implements WebMvcConfigurer {
// Code for generating templateEngine/Resolver ...
}
My controller (here I try to autowire the service, not sure if it is the correct place, causes the exception):
#Controller
public class IndexController {
private int count = 0;
#Autowired
private BuildingService buildingService;
// This line causes the exception
#GetMapping("/")
public String index(Model model) {
model.addAttribute("message", "Welcome to Hello World");
return "index";
}
// Some more mapping no use of service
}
My BuildingService:
public interface BuildingService {
Building save(Building building);
Building findById(String buildingId);
List<Building> findByCompanyId(String companyId);
Building findByCompanyAndAreaId(String companyId, String areaId);
List<Building> findByCompanyIdAndNameLike(String companyId, String name, int page);
List<Building> findByPhoneNumber(String telephoneNumber);
Long countBuildings(String companyId);
}
My BuildingServiceImpl:
#Service("BuildingService")
public class BuildingServiceImpl implements BuildingService {
#Autowired
private BuildingRepository buildingRepository;
#Override
public List<Building> findByCompanyId(String companyId) {
return buildingRepository.findByCompanyId(companyId);
}
public List<Building> findByCompanyIdAndNameLike(String companyId, String name, int page) {
return buildingRepository.findByCompanyIdAndNameLikeOrderByName(companyId, name, new PageRequest(page, 20))
.getContent();
}
#Override
public Building findByCompanyAndAreaId(String companyId, String areaId) {
return buildingRepository.findByCompanyAndAreaId(companyId, areaId);
}
#Override
public List<Building> findByPhoneNumber(String telephoneNumber) {
return buildingRepository.findByPhoneNumber(telephoneNumber);
}
#Override
public Building findById(String buildingId) {
return buildingRepository.findById(buildingId).get();
}
#Override
public Building save(Building building) {
return buildingRepository.save(building);
}
#Override
public Long countBuildings(String companyId) {
return buildingRepository.countBuildings(companyId);
}
}
The order classes are simple copied from the tutorial.

EDIT
At the end of the error message the following line stands, could that mean I am missing a dependency?

EDIT 2
After trying different approaches and reading more about Spring/Couchbase and Autowired, I now get the exception that No bean named 'couchbaseRepositoryOperationsMapping' available. The whole exception looks like this:

Override default RestTemplate in Spring Boot 2.1.1

I'm using Spring Boot 2.1.1, Spring Data REST, Spring HATEOAS, Hibernate.
In my #Configuration class I created a custom RestTemplate:
#Configuration
#EnableRetry
#EnableTransactionManagement
#EnableJpaAuditing(auditorAwareRef = "springSecurityAuditorAware")
public class CustomConfiguration {
#Bean
public RestTemplate restTemplate() {
RestTemplate restTemplate = new RestTemplateBuilder().setConnectTimeout(httpClientConnectionTimeout)
.setReadTimeout(httpClientReadTimeout).build();
ObjectMapper objectMapper = new ObjectMapper();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter(objectMapper));
restTemplate.getMessageConverters().add(new StringHttpMessageConverter());
restTemplate.getMessageConverters().add(0, new StringHttpMessageConverter(Charset.forName("UTF-8")));
return restTemplate;
}
I use this restTemplate in a #Component:
#Component
public class TenantRestClient {
#Autowired
private RestTemplate restTemplate;
public Tenant register(Tenant tenant) {
//my stuff here
}
Until Spring Boot 2.0.3 everything worked fine, but if I update to Spring 2.0.4 or greater, when I try to run my application I've this exception:

Do you have any hint to solve this strange error? And...why does it happen just updating to Spring Boot >=2.0.4 (same code)?

Try annotation restTemplate bean with #Primary.
#Bean
#Primary
public RestTemplate restTemplate() {
RestTemplate restTemplate = new RestTemplateBuilder().setConnectTimeout(httpClientConnectionTimeout)
.setReadTimeout(httpClientReadTimeout).build();
ObjectMapper objectMapper = new ObjectMapper();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter(objectMapper));

restTemplate.getMessageConverters().add(0, new StringHttpMessageConverter(Charset.forName("UTF-8")));
return restTemplate;
}

please try with below property in the application.properties of your spring boot project. Then it will allow you to override the existing bean definitions with our custom with the same name.
spring.main.allow-bean-definition-overriding=true
