报错：feign.FeignException$FeignClientException: [424 Failed Dependency] during [POST] to

  报错的原因是没有添加@Inner注解

在我们项目加载阶段，我们获取有Inner注解的类和方法，然后获取我们配置的uri，经过正则替换后面的可变参数为*，然后将此uri加入到ignore-url中。此时我们就能达到所有Inner配置的方法/类上的接口地址，都统一在项目加载阶段自动帮我们加到ignore-url中，不需要我们手动配置，免去了很多开发工作，同时也能避免我们忘记配置，而浪费开发时间。核心代码如下：

@Slf4j
@Configuration
@ConditionalOnExpression("!'${security.oauth2.client.ignore-urls}'.isEmpty()")
@ConfigurationProperties(prefix = "security.oauth2.client")
public class PermitAllUrlProperties implements InitializingBean {
private static final Pattern PATTERN = Pattern.compile("\\{(.*?)\\}");
@Autowired
private WebApplicationContext applicationContext;
@Getter
@Setter
private List<String> ignoreUrls = new ArrayList<>();
@Override
public void afterPropertiesSet() {
RequestMappingHandlerMapping mapping = applicationContext.getBean(RequestMappingHandlerMapping.class);
Map<RequestMappingInfo, HandlerMethod> map = mapping.getHandlerMethods();
map.keySet().forEach(info -> {
HandlerMethod handlerMethod = map.get(info);
// 获取方法上边的注解 替代path variable 为 *
Inner method = AnnotationUtils.findAnnotation(handlerMethod.getMethod(), Inner.class);
Optional.ofNullable(method)
.ifPresent(inner -> info.getPatternsCondition().getPatterns()
.forEach(url -> ignoreUrls.add(ReUtil.replaceAll(url, PATTERN, StringPool.ASTERISK))));
// 获取类上边的注解, 替代path variable 为 *
Inner controller = AnnotationUtils.findAnnotation(handlerMethod.getBeanType(), Inner.class);
Optional.ofNullable(controller)
.ifPresent(inner -> info.getPatternsCondition().getPatterns()
.forEach(url -> ignoreUrls.add(ReUtil.replaceAll(url, PATTERN, StringPool.ASTERISK))));
});
}
