我是 Spring Vault 的新手，对 Springboot 还有些陌生，我正在努力学习这一点，所以我需要帮助。抱歉，很长的帖子。
这是我建立的 Spring Vault 项目的来源，我在网上查看各种教程
凭据.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;
}
}
凭据服务.java
package com.example.vault.demoVault;
import java.net.URISyntaxException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.vault.core.VaultTemplate;
import org.springframework.vault.support.VaultResponseSupport;
/**
* Sample service to demonstrate storing and retrieval of secrets.
*
* NOTE: We need to configure Vault and provide the Vault uri in the properties file.
*
*/
@Service
public class CredentialService {
@Autowired
private VaultTemplate vaultTemplate;
/**
* To Secure Credentials
* @param credentials
* @return VaultResponse
* @throws URISyntaxException
*/
public void secureCredentials(Credential credentials) throws URISyntaxException {
vaultTemplate.write("secret/gs-vault-config", credentials);
}
/**
* To Retrieve Credentials
* @return Credentials
* @throws URISyntaxException
*/
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);
}
}
VaultConfig.java
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;
/**
* Example class to configure Vault beans using 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");
}
}
VaultRestController.java
package com.example.vault.demoVault;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.net.URISyntaxException;
@RestController
public class VaultRestController {
@Autowired
private CredentialService credentialService;
@GetMapping("/credential")
public ResponseEntity<Credential> getCredentialEndpoint() throws URISyntaxException {
Credential credential = credentialService.accessCredentials();
return new ResponseEntity<Credential>(credential, HttpStatus.OK);
}
}

当我运行这个项目时，我得到了错误

现在，根据我的理解，由于我正在扩展我VaultConfig.java的 fromAbstractVaultConfiguration我不需要 bootstrap.properties 文件来配置我的 Vault 客户端应用程序，spring 会选择这些配置并自行处理它，但显然这个没有发生并且应用程序没有启动，因为显然它需要那些 bootstrap.properties 配置。看来我的应用程序忘记了我的 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 文件放在我的项目中时，应用程序启动并且我特别提到了该属性spring.cloud.vault.scheme=http，但是当我调用我的终点时，它仍然给了我
javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection
错误期待 https 调用，我也不明白为什么。
任何帮助表示赞赏。提前致谢
