i find the root cause of this issue

see config/Docker.file

HEALTHCHECK --interval=10s --timeout=3s CMD curl -f http://localhost:8888/actuator/health || exit 1

values of 10s for interval and 3s for connect timeout is both too small, when the docker machine have a bit lo

像Laravel 的集合类的高阶消息，用起来就很 Nice，例如：

$collect->map(function($item){
       return $item['value'];
});
// 可以写成这样
$collect->map->value;

// 方法调用
$collect->map(function($item){
       return $item->foo();
});
// 可以写成这样
$collect->map->foo();

// ...

From RestTemplate.java#L78-L81

The RestTemplate will be deprecated in a future version and will not have major new features added going forward. See the WebClient section of the Spring Framework reference docume

1. Bug Description

SpringCloud+feign服务调用，参与方不回滚。例如：发起方A（注解使用的是@LcnTransaction，@transactional)
）通过feign调用参与方B（注解@LcnTransaction(propagation = DTXPropagation.SUPPORTS)
@transactional），B抛异常，A插入数据（不回滚）。
使用过的解决办法：
1，feign取消falback，不进行熔断，测试无效；
2，feign不取

如下：

databaseChangeLog:
  - changeSet: # 对应一个 ChangeSet 对象
      id: 0 # ChangeSet 编号
      author: calm # 作者
      comment: 空 # 备注

评论的属性是 comment，而不是comments，虽然表DATABASECHANGELOG 中相应的字段叫COMMENTS，正常的记录效果如下：

Is your feature request related to a problem? Please describe.
Currently, the guide https://spring.io/guides/gs/gateway/#_writing_tests suggest to use "WireMock from Spring Cloud Contract in order stand up a server".
Unit tests of the people using this library to make gateways would be more performant, easier to write and more stable if they didn't make real tcp connections to do http reques

The documentation should call out that monitoring secrets is disabled by default and that you need to set spring.cloud.kubernetes.reload.monitoring-secrets=true in order for it to work.

It can be a bit confusing
