这是我的个人版本，从@Unni版本开始，我只是玩了一点html标记.

This is my personal version started from @Unni version, I just played a little bit with html markup.

@Component
@Order(SwaggerPluginSupport.SWAGGER_PLUGIN_ORDER + 1)
public class OperationNotesResourcesReader implements OperationBuilderPlugin {
    private static final Logger LOG = Logger.getLogger(OperationNotesResourcesReader.class.getName());

    private final DescriptionResolver descriptions;

    @Autowired
    public OperationNotesResourcesReader(DescriptionResolver descriptions) {
        this.descriptions = descriptions;
    }

    @Override
    public void apply(OperationContext context) {
        try {
            StringBuilder sb = new StringBuilder();

            // Check authorization
            Optional<PreAuthorize> preAuthorizeAnnotation = context.findAnnotation(PreAuthorize.class);
            sb.append("<b>Access Privileges & Rules</b>: ");
            if (preAuthorizeAnnotation.isPresent()) {
                sb.append("<em>" + preAuthorizeAnnotation.get().value() + "</em>");
            } else {
                sb.append("<em>NOT_FOUND</em>");
            }

            // Check notes
            Optional<ApiOperation> annotation = context.findAnnotation(ApiOperation.class);
            if (annotation.isPresent() && StringUtils.hasText(annotation.get().notes())) {
                sb.append("<br /><br />");
                sb.append(annotation.get().notes());
            }

            // Add the note text to the Swagger UI
            context.operationBuilder().notes(descriptions.resolve(sb.toString()));
        } catch (Exception e) {
            LOG.log(Level.SEVERE, "Error when creating swagger documentation for security roles: ", e);
        }
    }

    @Override
    public boolean supports(DocumentationType delimiter) {
        return SwaggerPluginSupport.pluginDoesApply(delimiter);
    }
}

这是最终的渲染:
