Users must log in to different databases in a Java application (MVC, Spring)

Now I'm programming my Java application on Spring (MVC). Need some help with code. this is crm system. Web project. For one company there will be one base, for another another. I used spring boot and spring security for my project.
Thanks for help!
For now I have only one database with some count of users. I want to find some solution of my problem.
application.properties:
spring.datasource.url=jdbc:mysql://localhost:3306/crm?useSSL=false
spring.datasource.username=bestuser
spring.datasource.password=bestuser

Succesfully deployed Spring MVC webapp responds 404

pls, bear with me as I am a beginner and this is also my first question placed here.
I am having the following problem:
I have a Spring MVC web app deployed with a CI/CD procedure, an AWS EC2 instance, three docker containers: one is the app, another is MySQL and then the third one is Tomcat. It is a maven project, built with Jenkins from a Github repo. The instance is up, containers are running and communicating, war file is deployed successfully by Jenkins, the app is present on tomcats manager.html.
Deployment is java based without web.xml. No Docker file either, the app container is on Jenkins BlueOcean. For one thing that I've noticed, the WebApplicationInitializer and the config files are not being included in the war file, not sure if it is supposed to be this way or not...
This is as far as I have come. App doesn't respond. Unfortunately, I've never seen a java web app deployed this way, or in any other way for that matter, so I am entirely at a loss. On my localhost it was working fine. Any help is greatly appreciated, thank you in advance! Please let me know if further code is needed.
This is my WebApplicationInitializer implementation:
public class SOAppInitializer implements WebApplicationInitializer {
#Override
public void onStartup(ServletContext container) {
XmlWebApplicationContext appContext = new XmlWebApplicationContext();
appContext.setConfigLocation("classpath:application-config.xml");
DispatcherServlet dispatcherServlet = new DispatcherServlet(appContext);
ServletRegistration.Dynamic registration = container.addServlet("dispatcher", dispatcherServlet);
registration.setLoadOnStartup(1);
registration.addMapping("/");
}
}
and the configuration
#EnableWebMvc
#ComponentScan(basePackages = "com.ownproject.S********r")
#Configuration
public class AppConfig extends WebMvcConfigurerAdapter {
// Resolve logical view names to .html resources in the /WEB-INF/views directory
#Bean
ViewResolver viewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("WEB-INF/classes/templates");
return resolver;
}
#Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}

Please help me to find solution. Thank You

Your controller is probably not being picked up by the ComponentScan because you have limited to the package for the scan.
Try this:
// note #ComponentScan is removed as it is included already in #SpringBootApplication
#EnableJpaRepositories
#SpringBootApplication
public class CunsultustodayWebServicesApplication {
...
And This:
// note #Controller and #CompnentScan are removed
#RestController
public class LoginController {

Dependency error in Spring boot for Spring session and Redis. What is the correct dependency i have to use?

I have angular 2 front-end and spring boot back-end.I want to use username and password for login and then use x-auth-token to check session for each request sent from angular.I want to use Redis to store session.But i keep getting the below error when connecting to Redis.My assumption is my dependency version of spring session is causing the issue but i am not able to understand why that is? -
An attempt was made to call a method that does not exist. The attempt was made from the following location: org.springframework.session.data.redis.config.ConfigureNotifyKeyspaceEventsAction.getNotifyOptions(ConfigureNotifyKeyspaceEventsAction.java:74) The following method did not exist: org.springframework.data.redis.connection.RedisConnection.getConfig(Ljava/lang/String;)Ljava/util/List; The method's class, org.springframework.data.redis.connection.RedisConnection, is available from the following locations: jar:file:/C:/Users/Ajay/.m2/repository/org/springframework/data/spring-data-redis/2.3.3.RELEASE/spring-data-redis-2.3.3.RELEASE.jar!/org/springframework/data/redis/connection/RedisConnection.class The class hierarchy was loaded from the following locations: org.springframework.data.redis.connection.RedisConnection: file:/C:/Users/Ajay/.m2/repository/org/springframework/data/spring-data-redis/2.3.3.RELEASE/spring-data-redis-2.3.3.RELEASE.jar Action: Correct the classpath of your application so that it contains a single, compatible version of org.springframework.data.redis.connection.RedisConnection

I think pom.xml is bit messed up. You have conflicting dependencies.
Use below command to see details of which dependencies are loaded n which are omitted.
mvn dependency:tree -Dverbose -Dincludes=commons-collections
That will give you some insights.
https://maven.apache.org/plugins/maven-dependency-plugin/examples/resolving-conflicts-using-the-dependency-tree.html
Also in my opinion can you try removing below dependency and run the application.

dispatcherServletRegistration Spring boot exception

Help please, I try to put Vaadin on my (Spring boot) server and after I set up a simple example, I get the following error:
The bean 'dispatcherServletRegistration', defined in class path resource [com/vaadin/flow/spring/SpringBootAutoConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/DispatcherServletAutoConfiguration$DispatcherServletRegistrationConfiguration.class] and overriding is disabled.
Then, to correct the error, I write in application.prop:
spring.main.allow-bean-definition-overriding=true
and get the following error:
Parameter 1 of constructor in org.springframework.boot.autoconfigure.web.servlet.error.ErrorMvcAutoConfiguration required a bean of type 'org.springframework.boot.autoconfigure.web.servlet.DispatcherServletPath' that could not be found.

What is the version of vaadin-spring-boot-starter you are using ?
From this , it said this is the known issues when certain old version of vaadin-spring-boot-starter is used with Spring Boot 2.1 and it will be fixed in some newer release :
We have another working workaround and are also close to finding the
proper fix without the need for the workaround. Regardless which
approach we use first, next week we should have platform releases that
work with Spring Boot 2.1. (v10, v11 and v12)
Sorry for keeping you on hold before being able updating to Spring
Boot 2.1, we should have looked at this earlier - my bad.
Then from the release note here, it said version 10.1.0 supports Spring Boot 2.1. So my advice is to upgrade the vaadin-spring-boot-starter to at least 10.1.0 or the latest version.
