连接限制服务到spring cloud配置服务器失败

Question

关于上面的问题，我想请您帮忙。现在我正在尝试将应用程序（SpringCloudConfigServer）与另一个应用程序（limit-service）连接，limit-service应用程序必须选择SpringCloudConfigServer属性文件。当我点击http://localhost:8080/limits时，我需要像{“maximum”：888,“minimum”：8}一样获得oupput,但我得到的是{“maximum”：999,“minimum”：99}

这是我的堆栈跟踪

这是我的限额服务代码

package com.in28minutes.microservices.limitsservice;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class LimitsServiceApplication {



public static void main(String[] args) {
        SpringApplication.run(LimitsServiceApplication.class, args);
    }

}

`控制器

package com.in28minutes.microservices.limitsservice;

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

import com.in28minutes.microservices.limitsservice.bean.LimitConfiguration;

@RestController
public class LimitsConfigurationController {
    @Autowired
    private Configuration configuration;
    @GetMapping("/limits")
    public LimitConfiguration retrieveLimitsFromConfigurations() {
        return new LimitConfiguration(configuration.getMaximum(), 

configuration.getMinimum());

        }

    }

package com.in28minutes.microservices.limitsservice;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties("limits-service")
public class Configuration {
    private int minimum;
    private int maximum;
    public int getMinimum() {
        return minimum;
    }
    public int getMaximum() {
        return maximum;
    }
    public void setMinimum(int minimum) {
        this.minimum = minimum;
    }
    public void setMaximum(int maximum) {
        this.maximum = maximum;
    }



}

package com.in28minutes.microservices.limitsservice.bean;

public class LimitConfiguration {
    private int maximum;
    private int minimum;

    protected LimitConfiguration() {

    }

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

    public int getMaximum() {
        return maximum;
    }

    public int getMinimum() {
        return minimum;
    }   

}

spring.application.name=limits-service

spring.cloud.config.server.uri=http://localhost:8888

limits-service.minimum=8
limits-service.maximum=888

看起来配置服务器调用失败。这就是为什么您不能从配置服务器加载属性，而是从服务本地配置文件加载属性

找不到PropertySource：在“http://localhost:8888/limits-service/dev”的GET请求上出现I/O错误：连接被拒绝：connect；嵌套异常是java.net.ConnectException：Connection Delection：connect 2020-04-29 22:51:25.074 INFO 2016---[restartedMain]C.I.M.L.LimitsServiceApplication:以下配置文件处于活动状态:dev
