Spring Boot ConflictingBeanDefinitionException: Annotation-specified bean name for @Controller class

Question

I keep getting the ConflictingBeanDefinitionException error in my Spring boot application. I am not entirely sure as to how to address it, I have several @Con

I was having the same problem with a generated .war file from spring-boot. the approved solution (Timothy Tuti's own solution) didn't quite work for me exactly as-is, but I tweaked it a little bit and it worked. I just added the following line to my Application.java:

@ComponentScan(basePackages = { "com.mypackage" })

For reference, here goes my full Application.java

package com.inmoment.devchallenge;
import org.neo4j.graphdb.GraphDatabaseService;
import org.neo4j.graphdb.factory.GraphDatabaseFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.neo4j.config.EnableNeo4jRepositories;
import org.springframework.data.neo4j.config.Neo4jConfiguration;

@SpringBootApplication
@Configuration
@ComponentScan(basePackages = { "com.inmoment.devchallenge.controller" })
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {

    @Configuration
    @EnableNeo4jRepositories(basePackages = "com.inmoment.devchallenge.repository")
    static class ApplicationConfig extends Neo4jConfiguration {

        public ApplicationConfig() {
            setBasePackage("com.inmoment.devchallenge.repository");
        }

        @Bean
        GraphDatabaseService graphDatabaseService() {
            return new GraphDatabaseFactory().newEmbeddedDatabase("accessingdataneo4j.db");
        }
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

}
