## Spring Cloud Config使用Github的Webhooks功能出现400状态码 ##

最近在学习Spring Cloud Config，需要使用到Github提供的Webhooks功能，就是当配置文件更改后，Github会请求Config Server的`actuator/bus-refresh`接口（Bus组件提供的），这样Config Server和Config Client再结合`RabbitMQ`就能够实现配置文件动态更新的功能。

但是我配置了Github的Webhooks后，一直没有实现这个功能（无论是设置`actuator/bus-refresh`接口还是`monitor`接口都没用，因为缺少依赖，目前`monitor`这个接口是不存在的，所以出现404，而`actuator/bus-refresh`接口是有的，出现400的原因下面会说）。

我配置文件Repository的Webhooks设置如下图，这里使用了内网穿透工具[`natapp`][natapp]，这个就自己去了解吧。

导致出现400状态码的原因是GitHub通过你设置的Webhooks来请求你Config Server的接口，而这个请求的Json数据会导致你Config Server因为无法正常反序列化，从而导致出现400状态码。

解决方法是需要导入一个依赖：

<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-config-monitor</artifactId>
            </dependency>

导入之后，我的问题就解决了；导入这个依赖之后，`monitor`这个接口也就有了，这个依赖也帮我们处理了Github请求的Json数据会导致你Config Server因为无法正常反序列化的问题，所以Webhooks设置可以和上面那个图一样。

如果还不行，看看还有什么依赖没有导入，或者还缺少什么配置。

这是我Config Server的pom.xml:

因为需要使用到RabbitMQ，所以需要把这些都配置好（Config Server和Config Client），以及可能会更新的域是否使用`@RefreshScope`这个注解。
