我的Sping Boot 应用程序中不断出现ConflictingBeanDefinitionException错误。我不完全确定如何解决它，我有几个带注解的@Configuration类帮助设置Thymeleaf、Spring Security和Web。为什么应用程序尝试设置homeController两次？（它在哪里尝试这样做？）
错误为：

org.springframework.beans.factory.BeanDefinitionStoreException: 
Failed to parse configuration class [org.kemri.wellcome.hie.Application]; nested exception is org.springframework.context.annotation.ConflictingBeanDefinitionException:
Annotation-specified bean name 'homeController' for bean class [org.kemri.wellcome.hie.HomeController] conflicts with existing, non-compatible bean definition of same name and class [org.kemri.wellcome.hie.controller.HomeController]

我的Sping Boot 主应用程序初始化程序：

@EnableScheduling
@EnableAspectJAutoProxy
@EnableCaching
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
    
    @Override
    protected final SpringApplicationBuilder configure(final SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

}

我的数据库配置文件：

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages="org.kemri.wellcome.hie.repositories")
@PropertySource("classpath:application.properties")
public class DatabaseConfig {

  @Autowired
  private Environment env;

  @Autowired
  private DataSource dataSource;

  @Autowired
  private LocalContainerEntityManagerFactoryBean entityManagerFactory;

   @Bean
  public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(env.getProperty("spring.datasource.driverClassName"));
    dataSource.setUrl(env.getProperty("spring.datasource.url"));
    dataSource.setUsername(env.getProperty("spring.datasource.username"));
    dataSource.setPassword(env.getProperty("spring.datasource.password"));
    return dataSource;
  }
  @Bean
  public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean entityManagerFactory =
        new LocalContainerEntityManagerFactoryBean();
    
    entityManagerFactory.setDataSource(dataSource);
    
    // Classpath scanning of @Component, @Service, etc annotated class
    entityManagerFactory.setPackagesToScan(
        env.getProperty("spring.jpa.hibernate.entitymanager.packagesToScan"));
    
    // Vendor adapter
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    entityManagerFactory.setJpaVendorAdapter(vendorAdapter);
    
    // Hibernate properties
    Properties additionalProperties = new Properties();
    additionalProperties.put(
        "hibernate.dialect", 
        env.getProperty("spring.jpa.hibernate.dialect"));
    additionalProperties.put(
        "hibernate.showsql", 
        env.getProperty("spring.jpa.hibernate.showsql"));
    additionalProperties.put(
        "hibernate.hbm2ddl.auto", 
        env.getProperty("spring.jpa.hibernate.hbm2ddl.auto"));
    entityManagerFactory.setJpaProperties(additionalProperties);
    
    return entityManagerFactory;
  }
  @Bean
  public JpaTransactionManager transactionManager() {
    JpaTransactionManager transactionManager = 
        new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(
        entityManagerFactory.getObject());
    return transactionManager;
  }
  @Bean
  public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
    return new PersistenceExceptionTranslationPostProcessor();
  }

}

我的Thymeleaf配置文件：

@Configuration
public class ThymeleafConfig {

@Bean
public ServletContextTemplateResolver templateResolver(){
    ServletContextTemplateResolver thymeTemplateResolver = new ServletContextTemplateResolver();
    thymeTemplateResolver.setPrefix("/WEB-INF/views/");
    thymeTemplateResolver.setSuffix(".html");
    thymeTemplateResolver.setTemplateMode("HTML5");
    return thymeTemplateResolver;
}   

@Bean
public SpringSecurityDialect springSecurityDialect(){
    SpringSecurityDialect dialect = new SpringSecurityDialect();
    return dialect;
}

@Bean
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine engine = new SpringTemplateEngine();   
    engine.addTemplateResolver(templateResolver());
    Set<IDialect> dialects = new HashSet<IDialect>();
    dialects.add(springSecurityDialect());
    engine.setAdditionalDialects(dialects);     
    return engine;
}

@Bean
public ThymeleafViewResolver thymeleafViewResolver() {
    ThymeleafViewResolver resolver = new ThymeleafViewResolver();
    resolver.setTemplateEngine(templateEngine());
    resolver.setViewClass(ThymeleafTilesView.class);
    resolver.setCharacterEncoding("UTF-8");
    return resolver;
}

}
我的Web配置类：

@Configuration
@PropertySource("classpath:application.properties")
public class WebConfig extends WebMvcAutoConfigurationAdapter  {
    
    @Autowired
    private Environment env;
    
    @Bean
    public JavaMailSenderImpl javaMailSenderImpl() {
        JavaMailSenderImpl mailSenderImpl = new JavaMailSenderImpl();
        mailSenderImpl.setHost(env.getProperty("smtp.host"));
        mailSenderImpl.setPort(env.getProperty("smtp.port", Integer.class));
        mailSenderImpl.setProtocol(env.getProperty("smtp.protocol"));
        mailSenderImpl.setUsername(env.getProperty("smtp.username"));
        mailSenderImpl.setPassword(env.getProperty("smtp.password"));
        Properties javaMailProps = new Properties();
        javaMailProps.put("mail.smtp.auth", true);
        javaMailProps.put("mail.smtp.starttls.enable", true);
        mailSenderImpl.setJavaMailProperties(javaMailProps);
        return mailSenderImpl;
    }

    @Bean
    public CacheManager cacheManager() {
        return new ConcurrentMapCacheManager();
    }
}

我的控制器（设置控制器时出错）

@Controller
public class HomeController {
    
    private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
    
    /**
     * Simply selects the home view to render by returning its name.
     */
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String home(Locale locale, Model model) {
        logger.info("Welcome home! The client locale is {}.", locale);
        
        Date date = new Date();
        DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
        
        String formattedDate = dateFormat.format(date);
        
        model.addAttribute("serverTime", formattedDate );
        
        return "index.html";
    }
}

什么可能导致我的控制器类出现ConflictingBeanDefinitionException错误？
