无法实例化 VaultConfigDataLoader
Unable to instantiate VaultConfigDataLoader
我正在尝试在我的 Spring 启动应用程序（v. 2.4.2）中配置 Spring Cloud Vault。我正在使用 Spring Cloud v. 2020.0.5（根据 Release train，应该没问题）。

知道哪里出了问题吗？我是否遗漏了一些依赖项？
我发现了问题。似乎这些特定的版本集不兼容（即使发布列车另有说明）：
- spring-boot2.4.2
- spring-cloud 2020.0.5
问题是 class ConfigDataLoaders 仅在 spring-boot 2.4.3:
中支持 DeferredLogFactory 注入
https://github.com/spring-projects/spring-boot/commit/1def245a2cb7f5aa520531059956c3c3794625d7
另一方面，从 Spring Cloud 3.0.2 开始，VaultConfigDataLoader 有一个接受 DeferredLogFactory 的新构造函数：
https://github.com/spring-cloud/spring-cloud-vault/commit/a9fd88c3b768a1f6e485851423dd8f62afae71ba
因此，要么使用 Spring Boot 2.4.2 和 Spring Cloud 3.0.1（或更低版本），要么使用 Spring Boot 2.4.3 和 Spring Cloud 3.0.2+.
我希望这次调查能节省一些时间，因为我花了大约半天的时间..
我正在尝试在我的 Spring 启动应用程序（v. 2.4.2）中配置 Spring Cloud Vault。我正在使用 Spring Cloud v. 2020.0.5（根据 Release train，应该没问题）。

知道哪里出了问题吗？我是否遗漏了一些依赖项？
我发现了问题。似乎这些特定的版本集不兼容（即使发布列车另有说明）：
- spring-boot2.4.2
- spring-cloud 2020.0.5
问题是 class ConfigDataLoaders 仅在 spring-boot 2.4.3:
中支持 DeferredLogFactory 注入https://github.com/spring-projects/spring-boot/commit/1def245a2cb7f5aa520531059956c3c3794625d7
另一方面，从 Spring Cloud 3.0.2 开始，VaultConfigDataLoader 有一个接受 DeferredLogFactory 的新构造函数：
https://github.com/spring-cloud/spring-cloud-vault/commit/a9fd88c3b768a1f6e485851423dd8f62afae71ba
因此，要么使用 Spring Boot 2.4.2 和 Spring Cloud 3.0.1（或更低版本），要么使用 Spring Boot 2.4.3 和 Spring Cloud 3.0.2+.
我希望这次调查能节省一些时间，因为我花了大约半天的时间..
