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

Question

I am using spring boot 2.4.5 and trying to configure spring cloud server to read property file from local git repository. Below links are for service startup and spring cloud server startup logs,

limits-service: https://drive.google.com/file/d/1U6o2UzdHDquyzsyUv0Im3h0RqbFXaCJG/view?usp=sharing

spring-cloud-config-server: https://drive.google.com/file/d/1A5J0S7sZRMQfeb2Hv94slgt4o5xtjsEo/view?usp=sharing

After all configurations, the URL, http://localhost:8888/limits-service/default returns 404 as below,

Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback.

Class Limits:

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 + "]";
  }

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

Git repo directory location(I use Windows):

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

Answer 1

Your read the application.properties file add Component field @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;
  }
 } 

This file 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
