I just did this project to learn about spring boot. and i just need to find why i have this error and how i can solve it

it didn't choose the right version of the driver.
so I change the drive version on https://cloud.mongodb.com/ to 3.4 or later and it give me an other url to connect and it work

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'

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);
}
}

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

Springboot test failed to load ApplicationContext in Junit 5

I'm trying to create unit/integration test using Junit5 for specific service classes to avoid overload the whole project.

The problem is that you really don't have a JavaMailSender available (and you wouldn't want a real one during your tests). You have four options:
Register a mock/stub JavaMailSender bean in a test configuration.
Use auto-configuration to make your EmailSenderService itself #ConditionalOnBean(JavaMailSender.class) and register a stub if there isn't one (this is usually what I do for testing "does the system send transactional mail?").
In this case, since you're actually trying to test the EmailSenderService itself, set spring.mail.host: localhost in your application-test properties (or an annotation).
Don't use Spring DI at all here. The major advantage of constructor injection is that you can hand-instantiate your beans, and you could new up your EmailSenderService and its dependencies.
If I understand the intended scope of your test, #3 is probably the solution to go with for you.

Spring Boot can't find classpath property from dependency module

I currently have a Spring Boot application with a dependency to a Java module. This Java module has some classpath properties. When I #Autowired a bean from the Java module in my Spring Boot application and define this bean with a #Bean annotation and then run the Spring Boot application it will throw errors.
Error thrown:

Bean definition in Spring Boot application
#Bean (name = "mailSubscriptionDao")
public MyService getMyService() {
return new MyServiceImpl();

Try to get the whole properties object injected
#Autowired
Properties myClassPathProperties;
If this works, you know you have loaded myproject-context.xml correctly.
Than you can also have a look with the debugger, whether a property with name 'property.x' exists or not.

Using Spring Boot & Spring Integration with database backed Configuration

For spring boot + integration application, I'm attempting to load configuration from database, allow it to be accessible to Spring's Environment & inject-able via #Value annotation and be override-able by externalized configurations as described in the spring boot reference documentation under the Externalized Configuration Section.
The problem I'm having is that my spring Integration XML contains ${input} property placeholders that can not be resolved, because I can't get the database backed configuration to be loaded before Spring attempts to load the XML configurations.
The entry point to the application:
#SpringBootApplication
public class TestApplication {
public static void main(String[] args) {
SpringApplication.run(TestApplication.class, args);
}
}
How database configuration would be loaded:
#Configuration
public class DbPropertiesConfig {
#Autowired
private org.springframework.core.env.Environment env;
#PostConstruct
public void initializeDatabasePropertySourceUsage() {
MutablePropertySources propertySources = ((ConfigurableEnvironment) env).getPropertySources();
try {
// The below code will be replace w/ code to load config from DB
Map<String,Object> map = new HashMap<>();
map.put("input-dir","target/input");
map.put("output-dir","target/output");
DbPropertySource dbPropertySource = new DbPropertySource("si",map);
propertySources.addLast(dbPropertySource);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
How Spring Integration config is loaded:
#Profile("IN")
#Configuration
#ImportResource({"si-common-context.xml","si-input-context.xml"})
public class SiInputAppConfig {
}
The Spring Integration XML configurationsi-input-context.xml:
<?xml version="1.0" encoding="UTF-8"?>

Spring loads DbPropertiesConfig after XML configuration is attempted to be loaded.
How can I resolve this issue?
Thanks in advance
AP

Yes, I can confirm by my home tests that XML definitions are loaded before the annotation stuff. It's enough complicated to determine why it is, but I'm sure that #Import* resources are more important by premise than an internal #Configuration logic.
Therefore your #PostConstruct isn't good for mix with XML.
One solution is to move all Spring Integration configuration to the Annotation style and even consider to use Spring Integration Java DSL.
Another solution is to follow with Spring Boot's Externalized Configuration recommendation:
Default properties (specified using SpringApplication.setDefaultProperties).
That means you have to read properties from your DB before the starting Spring Application. Yes, if you were going to use DataSource on the matter from the same application, it won't be possible. From other side let's take a look to your goal one more time! You are going to load properties for the application from DB as an external configuration, so, what is the point to do that from the application itself? Of course, it would be more safe to load and feed properties before application start.
Hope I am clear.
