Spring Vault无法访问k / v对

Question

我正在尝试设置一个简单的springboot应用程序，并使用Spring Vault存储DB和API凭据。

但是我正努力访问我的键值对。当我尝试在控制器中访问它（仅出于测试目的）时，它将引发IllegalArgumenException

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'vaultController': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'username' in value "${username}"

有人了解为什么这不起作用吗？

我遵循此仓库中的代码：https://github.com/rwinch/spring-vault-talk/tree/master/hello-spring-vault

到目前为止我所做的：

• 使用命令在本地运行保管库

vault server -dev -dev-root-token-id=12345

• 使用命令添加了键值

vault kv put secret/spring-vault-demo username=foo password=bar

• 设置一个简单的Spring Boot应用程序

控制器

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class VaultController {


    @Value("${username}")
    String username;


    @GetMapping("/vault")
    public String vault(){
        return "This value is from vault: " + username;
    }
}

VaultConfig

import org.springframework.context.annotation.Configuration;
import org.springframework.vault.annotation.VaultPropertySource;
import org.springframework.vault.authentication.ClientAuthentication;
import org.springframework.vault.authentication.TokenAuthentication;
import org.springframework.vault.client.VaultEndpoint;
import org.springframework.vault.config.AbstractVaultConfiguration;

import java.net.URI;

@Configuration
@VaultPropertySource("secrets/spring-vault-demo")
public class VaultConfig extends AbstractVaultConfiguration {

    @Override
    public VaultEndpoint vaultEndpoint() {
        String uri = getEnvironment().getProperty("vault.uri");
        if (uri != null){
            return VaultEndpoint.from(URI.create(uri));
        }else throw new IllegalStateException();
    }

    @Override
    public ClientAuthentication clientAuthentication() {
        String token = getEnvironment().getProperty("vault.token");
        if (token != null){
            return new TokenAuthentication(token);
        }else throw new IllegalStateException();
    }
}

Application.properties

vault.uri=http://localhost:8200
vault.token=12345

如果有人正在寻找解决方案：

阅读完文档后，我发现您必须添加具有更多配置的Bootstrap.properties文件

这是我的bootstrap.yml的样子

spring:
  application:
    name: spring-vault-demo
  cloud:
    vault:
      token: 12345
      scheme: http
