registration.setLoadOnStartup(webMvcProperties.getServlet().getLoadOnStartup());
multipartConfig.ifAvailable(registration::setMultipartConfig);
return registration;

return registration;
}

Description:
Parameter 2 of method servletEndpointRegistrar in org.springframework.boot.actuate.autoconfigure.endpoint.web.ServletEndpointManagementContextConfiguration$WebMvcServletEndpointManagementContextConfiguration required a single bean, but 2 were found:
- dispatcherServletRegistration: defined by method 'dispatcherServletRegistration' in class path resource [com/xxx/config/SpringMvcConfig.class]
- staDispatcherServletRegistration: defined by method 'staDispatcherServletRegistration' in class path resource [com/xxx/config/SpringMvcConfig.class]
Action:
Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed
Comment From: wilkinsona
As described in its javadoc, DispatcherServletRegistration a ServletRegistrationBean for the auto-configured DispatcherServlet. There should only be one such bean in your application. In most cases it will be provided by DispatcherServletAutoConfiguration, but you can define one of your own if you want the auto-configuration to back off. If you want to register additional DispatcherServlets, you should use a standard ServletRegistrationBean to do so. Alternatively, you could mark one of them as @Primary as suggested by the error message.

I just want to mapping two url-pattern for DispatcherServlet ,like web.xml :
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/my-ui/service/*</url-pattern>
</servlet-mapping>

I've tried to describe a couple of options for doing that above. The ServletRegistrationBean approach would look something like this:
@Bean
public ServletRegistrationBean<DispatcherServlet> staDispatcherServletRegistration(
DispatcherServlet dispatcherServlet, WebMvcProperties webMvcProperties,
ObjectProvider<MultipartConfigElement> multipartConfig) {
ServletRegistrationBean<DispatcherServlet> registration = new ServletRegistrationBean<>(dispatcherServlet,
"/my-ui/service/");
registration.setName("staDispatcherServlet");
registration.setLoadOnStartup(webMvcProperties.getServlet().getLoadOnStartup());
multipartConfig.ifAvailable(registration::setMultipartConfig);
return registration;
}
