Consider defining a bean of type 'java.lang.String' in your configuration. in spring boot migration project

I am working on the spring boot migration project from spring mvc+webflow to spring boot. During runtime, I am getting the below error.
*************************** APPLICATION FAILED TO START ***************************
Description:
Parameter 1 of constructor in
com.geodan.lgr.support.ExtendedLdapAuthoritiesPopulator required a
bean of type 'java.lang.String' that could not be found.
Action:
Consider defining a bean of type 'java.lang.String' in your
configuration.
Class: ExtendedLdapAuthoritiesPopulator
Constructor:
public ExtendedLdapAuthoritiesPopulator(ContextSource contextSource,
String groupSearchBase) {
super(contextSource, groupSearchBase);
ldapTemplate = new SpringSecurityLdapTemplate(contextSource);
}
The parameter String groupSearchBase creates this error. How to make Spring not creating bean for inbuilt classes?

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

I found the solution for the scanning problem which leads to the error of Bean not found from https://shekerama.wordpress.com/2017/03/25/how-to-solve-java-lang-illegalargumentexception-not-an-managed-type/.
final LocalContainerEntityManagerFactoryBean entityManagerFactory = new LocalContainerEntityManagerFactoryBean();

any ideas why the dataCollector service won't get fanout.exchange from the config server?

Is your file loaded in spring context? Can you see the file in the log something like below:

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?
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'couchbaseRepositoryOperationsMapping' available

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:

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:
2017-02-07 12:16:03.188 WARN 17620 --- [on(4)-127.0.0.1] ationConfigEmbeddedWebApplicationContext :

Try to get the whole properties object injected
#Autowired

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.
