1.Spring Boot Actuator Starter的使用 Starter for using Spring Boot's Actuator which provides production-ready features to help you monitor and manage your application

2.spring consul的使用

org.springframework.cloud spring-cloud-consul-config

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-consul-discovery</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-netflix-core</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-ribbon</artifactId>
    </dependency>

3.关键实现类，spring-cloud-consul-config下的ConfigWatch

@Scheduled(fixedDelayString = "${spring.cloud.consul.config.watch.delay:1000}")

Config Watch 固定延时获取配置 https://cloud.spring.io/spring-cloud-consul/spring-cloud-consul.html#spring-cloud-consul-config-watch

解决方法如下：

1.请求参数设置 http://xxx/v1/kv/pds/pds-asm/?recurse&wait=55s&index=801516等 2.响应结果的index缓存和比较 org.springframework.cloud.consul.config.ConfigWatch#consulIndexes来自于项目启动创建的org.springframework.cloud.consul.config.ConsulPropertySourceLocator#contextIndex
