无法使用 spring-cloud-config-server 从本地 git 存储库读取配置

Question

我正在使用 spring 启动 2.4.5 并尝试配置 spring 云服务器以从本地 git 存储库读取属性文件。 以下链接用于服务启动和 spring 云服务器启动日志，

弹簧云配置服务器： https://drive.google.com/file/d/1A5J0S7sZRMQfeb2Hv94slgt4o5xtjsEo/view?usp=sharing

完成所有配置后，URL、 http://localhost:8888/limits-service/default返回 404，如下所示，

Whitelabel 错误页面 此应用程序没有针对 /error 的显式映射，因此您将其视为后备。

Class 限制：

package com.home.microservices.limitsservice.bean;


public class Limits {

  private int minimum;
  private int maximum;

  public Limits() {
    super();
  }

  public Limits(int minimum, int maximum) {
    super();
    this.minimum = minimum;
    this.maximum = maximum;
  }

  public int getMinimum() {
    return minimum;
  }

  public void setMinimum(int minimum) {
    this.minimum = minimum;
  }

  public int getMaximum() {
    return maximum;
  }

  public void setMaximum(int maximum) {
    this.maximum = maximum;
  }

  @Override
  public String toString() {
    return "Limits [minimum=" + minimum + ", maximum=" + maximum + "]";
  }
}

Controller：

package com.home.microservices.limitsservice.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import com.home.microservices.limitsservice.bean.Limits;
import com.home.microservices.limitsservice.Configuration;

@RestController
public class LimitsController {

  @Autowired
  private Configuration configuration;

  @GetMapping("/limits")
  public Limits retrieveLimits() {
    return new Limits(configuration.getMinimum(), configuration.getMaximum());
  }
}

配置：

@Component
@ConfigurationProperties("limits-service")
public class Configuration {

  private int minimum;
  private int maximum;
  
  public int getMinimum() {
    return minimum;
  }

  public void setMinimum(int minimum) {
    this.minimum = minimum;
  }

  public int getMaximum() {
    return maximum;
  }

  public void setMaximum(int maximum) {
    this.maximum = maximum;
  }
}

application.properties（限制服务）：

logging.level.org.springframework = debug

Git repo 目录位置（我使用 Windows）：

D:\Learning\Microservices\git-localconfig-repo\limits-service.properties

Answer 1

您阅读 application.properties 文件添加组件字段@value

 @Component
 @PropertySource("file:D:\Learning\Microservices\git-localconfig- 
 repo\application.properties")
 @ConfigurationProperties(prefix="limits-service")
 public class Configuration {

 @Value("${minimum}")
 private int minimum;
 @Value("${maximum}")
 private int maximum;

 public int getMinimum() {
 return minimum;
 }

 public void setMinimum(int minimum) {
 this.minimum = minimum;
 }

 public int getMaximum() {
 return maximum;
 }

 public void setMaximum(int maximum) {
  this.maximum = maximum;
  }
 } 

此文件 application.properties

logging.level.org.springframework = debug
spring.application.name=limits-service
spring.config.import=optional:configserver:http://localhost:8888
limits-service.minimum=3
limits-service.maximum=997
