java - HikariCP和kafka在热重载配置映射spring boot Kubernetes时重置和重载事件模式不起作用

问题描述

我按照教程并在 k8s spring boot 应用程序中实现热重载配置映射：

  1. 添加行家
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-kubernetes-config</artifactId>
            <version>1.1.0.RELEASE</version>
        </dependency>
  1. 在资源中添加配置
spring.cloud.kubernetes.reload.enabled=true
gw.hotReloadValue=2222
  1. 类属性
@Getter
@Setter
@ToString
@RefreshScope
@ConfigurationProperties(prefix = "gw")
public class GWProperties {
    public int hotReloadValue;
    public GWProperties(){
    }
}

当我更改 gw.hotReloadValue 的值时它可以工作，但它有 2 个问题

更新：对于第一个问题，这是因为我的 pom 文件中的配置覆盖了热重载事件模式的配置，我删除了 jacyspt 依赖项，因此热重载事件自动检测而不调用执行器/刷新删除以下依赖项：

    <dependency>
        <groupId>com.github.ulisesbocchio</groupId>
        <artifactId>jasypt-spring-boot-starter</artifactId>
        <version>1.15</version>
    </dependency>
