我是 Spring Vault 的新手，也是 Springboot 的新手，我正在尝试学习这个，所以我需要帮助。不过，对于这篇很长的帖子，我们深表歉意。
这是我在网上查看各种教程所建立的 Spring Vault 项目的来源
Credential.java
package com.example.vault.demoVault;
public class Credential {
private String username;
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}

*/
@Service
public class CredentialService {
@Autowired
private VaultTemplate vaultTemplate;
/**

vaultTemplate.write("secret/gs-vault-config", credentials);
}
/**

public Credential accessCredentials() throws URISyntaxException {
VaultResponseSupport<Credential> response = vaultTemplate.read("secret/gs-vault-config", Credential.class);
return response.getData();
}
}
DemoVaultApplication.java
package com.example.vault.demoVault;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class DemoVaultApplication{
public static void main(String[] args) {
SpringApplication.run(DemoVaultApplication.class, args);
}
}

package com.example.vault.demoVault;
import org.springframework.context.annotation.Configuration;
import org.springframework.vault.authentication.ClientAuthentication;
import org.springframework.vault.authentication.TokenAuthentication;
import org.springframework.vault.client.VaultEndpoint;
import org.springframework.vault.config.AbstractVaultConfiguration;
/**

@Configuration
public class VaultConfig extends AbstractVaultConfiguration {
@Override
public VaultEndpoint vaultEndpoint() {
VaultEndpoint endpoint = new VaultEndpoint();
endpoint.setScheme("http");
return new VaultEndpoint();
}
@Override
public ClientAuthentication clientAuthentication() {
return new TokenAuthentication("00000000-0000-0000-0000-000000000000");
}
}

@Autowired
private CredentialService credentialService;
@GetMapping("/credential")
public ResponseEntity<Credential> getCredentialEndpoint() throws URISyntaxException {
Credential credential = credentialService.accessCredentials();
return new ResponseEntity<Credential>(credential, HttpStatus.OK);
}

现在，根据我的理解，由于我从 VaultConfig.java 扩展了我的 AbstractVaultConfiguration，因此我不需要 bootstrap.properties 文件来配置我的保险库客户端应用程序，spring 会选择设置这些配置并自行处理它，但显然这不会发生并且应用程序无法启动，因为显然它需要那些 bootstrap.properties 配置。看来我的应用程序没有注意到我的 VaultConfig，我在其中设置了一个简单的端点以通过 http 工作并使用我的根令牌进行身份验证。我在这里错过了什么吗？我无法弄清楚查看互联网上的示例
如果应用程序确实需要这样的 bootstrap.properties
spring.application.name=gs-vault-config
spring.cloud.vault.token=00000000-0000-0000-0000-000000000000
spring.cloud.vault.scheme=http
spring.cloud.vault.kv.enabled=true
那么 VaultConfig 和 AbstractVaultConfiguration 的意义何在？
此外，当我将 bootstrap.properties 文件放入我的项目时，应用程序会启动并且我特别提到了属性 spring.cloud.vault.scheme=http 但是当我调用我的端点时它仍然给了我
javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection
期待 https 调用的错误，我也不明白为什么。
感谢任何帮助。提前致谢
