Note: The cloud dependency of the client here is: spring-cloud-starter-config, and the server side is spring-cloud-config-server, otherwise an error will be reported, indicating that the bean cannot be generated, and the autowired cannot be used.

There is no need to add annotations to the program entry, just use the automatically generated ones

Configure bootstrap.properties under the resource package to  add configuration items

spring.application.name=didispace
spring.cloud.config.profile=dev
spring.cloud.config.label=master
spring.cloud.config.uri=http://localhost:7001/

server.port=7820

Note: The name item above must be the same as the name of the bunch of configuration files in the warehouse

The configuration in the Git repository is on the server side, as follows:

didispace.properties

didispace-dev.properties

didispace-prod.properties

didispace-test.properties

create a controller 

package com.smart.web;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by wanghan on 2018/4/26.
 */
@RefreshScope
@RestController
public class TestController {

    @Value("${from}")
    private String from;

    @RequestMapping("/service")
    public String from() {

        return this.from;
    }

    public void setFrom(String from) {
        this.from = from;
    }

    public String getFrom() {
        return from;
    }
}

 

Start the service and visit http://localhost:7820/service to display the contents of the configuration

git-dev-1.0

 

Since bootstrap.properties accesses didispace-dev.properties, the result of the above access is the configuration content of the Git repository didispace-dev.properties file
