Spring引导+重试+执行器刷新尝试失败

问题描述 投票：0回答：4

这里是用作参考的 Spring 存储库（我的项目也发生了同样的情况）：https://github.com/spring-guides/gs-centralized-configuration.git

如果我将这些依赖项添加到

complete/configuration-client
模块

implementation 'org.springframework.cloud:spring-cloud-starter-bootstrap'
implementation 'org.springframework:spring-aspects'
implementation 'org.springframework.retry:spring-retry'

将这样的

bootstrap.yml
添加到同一模块中：

spring:
  cloud:
    config:
      enabled: true
      uri: http://localhost:8888
      retry:
        initial-interval: 2500
        max-attempts: 10
        max-interval: 7000
        multiplier: 1.5
      fail-fast: true # line 1

如果我启动配置服务器（

complete/configuration-service
）和具有上述配置的客户端，我将无法通过
actuator/refresh
端点刷新客户端。我收到以下错误：

如果我删除 

line 1
中的 
bootstrap.yml
，刷新尝试就会成功。

Spring重试使用有没有错误？

java spring spring-boot spring-boot-actuator spring-retry

另一个解决方法是添加以下 JVM 选项。原因可能是 Java 模块系统更严格的可见性规则。

--add-opens java.base/java.lang=ALL-UNNAMED

您不需要添加以下对complete/configuration-client模块的依赖，因为您已经添加了spring-cloud-starter-config。

implementation 'org.springframework.cloud:spring-cloud-starter-bootstrap'

您可以将配置添加到 application.properties 文件complete/configuration-client，如下所示：

spring.config.import=optional:configserver:http://localhost:8888/
management.endpoints.web.exposure.include=*

logging.level.root=debug

spring.cloud.config.fail-fast=true
spring.cloud.config.uri=http://localhost:8888
spring.cloud.config.enabled=true

spring.cloud.config.retry.initial-interval=2500
spring.cloud.config.retry.max-attempts=10
spring.cloud.config.retry.max-interval=7000
spring.cloud.config.retry.multiplier=1.5

bootstrap.yml 是 spring-cloud-starter-bootstrap 的配置文件，但您不需要此依赖项和此配置文件。 我测试了它并为我工作。

问题出在Java版本上。当我从 Java 16 切换到 Java 8 时它就消失了。

对于我来说

实现“org.springframework.cloud：spring-cloud-starter-bootstrap”

这家伙给我带来了很多噩梦。我在 application.properties 中维护配置，而不是在 bootstrap.yml 中，所以不需要添加上述依赖项。如果它在类路径中，当您点击执行器/刷新时，spring将使用LegacyContextRefresher而不是ConfigDataContextRefresher。在 LegacyContextRefresher 的情况下发生了什么，环境变量在内部用作 StandardEnvironment 而不是 ApplicationServletEnvironment，因此无法从 application.properties 读取属性。
