Spring cloud config distributed configuration center client

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

注意：上面的name项必须与仓库里面那一堆配置文件的名称一致

Git仓库里面的配置就是服务器那边的，如下：

didispace.properties

didispace-dev.properties

didispace-prod.properties

didispace-test.properties

建立一个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;
    }
}

启动服务访问 http://localhost:7820/service 会显示配置里面的内容

git-dev-1.0

由于bootstrap.properties里面访问的是didispace-dev.properties 所以上面访问结果就是Git仓库 didispace-dev.properties 文件的配置内容
