【问题描述】：
我正在尝试做一些我认为很简单的事情。我想用Consul 进行配置，Vault 用于机密。
我正在寻找一个像这样的简单应用程序，它允许我从 Consul 获取配置和服务，以及从 Vault 获取秘密。
在我的示例中，Consul 和 Vault 是连接的，我可以在 Consul 服务和键值存储中看到 Vault。
在 Postman 中，我可以直接查询 Vault 并在 {{vault_url}}/v1/secret/interservice-bus/data-categorizer 中查看我的数据
现在我在测试应用中看不到 Consul 或 Vault 值。
我的 application.yml 很简单
spring:
profiles:
active: dev
main:
banner-mode: "CONSOLE"
application:
name: test-consul
logging:
level:
org: INFO
bootstrap.yml 是我进行大部分配置的地方。其中一些是重复的，因为如果缺少不同的部分，Spring 会抱怨。我不知道为什么。
spring:
profiles:
active: vault, dev
cloud:
consul:
host: 127.0.0.1
port: 8500
config:
enabled: true
discovery:
prefer-ip-address: true
config:
discovery:
enabled: true
service-id: vault
server:
vault:
host: localhost
port: 8200
scheme: http
authentication: TOKEN
token: 00000000-0000-0000-0000-000000000000
vault:
host: localhost
port: 8200
scheme: http
connection-timeout: 5000
read-timeout: 15000
authentication: TOKEN
config:
order: -10
token: 00000000-0000-0000-0000-000000000000
discovery:
enabled: true
service-id: vault
上面的令牌被遮盖了，但确实与保管库的根令牌匹配。
这是我的 POM

这是我正在尝试运行的简单应用程序
package com.example.demo;
import javax.annotation.PostConstruct;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableAutoConfiguration
@RefreshScope
@SpringBootApplication
@EnableDiscoveryClient
public class DemoApplication {
@Autowired
org.springframework.cloud.client.discovery.DiscoveryClient discoveryClient;
@Value("${test}")
private String testString;
@Value("${interservice-bus.data-categorizer.username}")
private String user;
@Value("${interservice-bus.data-categorizer.password}")
private String password;
@PostConstruct
public void setRabbitMQLocation() {
if (discoveryClient == null) {
System.out.println("******************************ERROR: Discovery Client is null******************************");
return;
}
System.out.println("****************************** Discovery Client is ACTIVE ******************************");
org.springframework.cloud.client.ServiceInstance serviceInstance =
discoveryClient.getInstances("interservice-bus")
.stream()
.findFirst()
.orElseThrow(() -> new RuntimeException("ERROR: " + "interservice-bus" + " not found"));
System.out.println("****************************** ISB is " + serviceInstance.getHost() + ":" + serviceInstance.getPort() + " ******************************");
}
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
它没有找到“测试”。我正在尝试从 Vault 中提取用户名和密码，并从 Consul 进行测试。
我来了
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2018-06-20 16:30:33.580 ERROR 92722 --- [ main] o.s.boot.SpringApplication : Application run failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.demoApplication': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'test' in value "${test}"
我正在寻找一个像这样的简单应用程序，它允许我从 Consul 获取配置和服务，以及从 Vault 获取秘密。
通过在网上搜索和查看示例，我不清楚是否还需要引入 Vault 依赖项，或者我是否从 Consul 获取所有内容（因此不需要 Vault 依赖项）。
