Tomcat的Bean创建异常。不能创建的Bean的名字是ServletEndpointRegistrar

public class ServletEndpointManagementContextConfiguration {

        @Configuration
    @ConditionalOnClass(ResourceConfig.class)
    @ConditionalOnMissingClass("org.springframework.web.servlet.DispatcherServlet")
    public static class JerseyServletEndpointManagementContextConfiguration {

        @Bean
        public ServletEndpointRegistrar servletEndpointRegistrar(
                WebEndpointProperties properties,
                ServletEndpointsSupplier servletEndpointsSupplier) {
            return new ServletEndpointRegistrar(properties.getBasePath(),
                    servletEndpointsSupplier.getEndpoints());
        }

    }

}
