springcloud(1) : 自定义配置中心并实现读取配置启动项目

1.定义http配置接口

接口名为 : /springbootService/server01,完整接口路径如下

http://127.0.0.1:10001/springbootService/server01

注 : springbootService在其他服务中定义,server01为配置名称

接口响应格式与内容如下

{
    "name":"springbootService",
    "profiles":[
        "server01"
    ],
    "label":null,
    "propertySources":[
        {
            "name":"http://127.0.0.1:10001/springbootService/server01",
            "source":{
                "name":"001",
                "server.port":"8002"
            }
        }
    ],
    "version":null,
    "state":null
}

说明 : 只需要关注 source 属性即可

对象类如下

Environment

package com.aliyun.industry.configuration.biz.model.config;

import java.util.List;

/**
 * @Auther: liyue
 * @Date: 2020/5/6 18:13
 * @Description:
 */
public class Environment {
    private String name;
    private String[] profiles;
    private String label;
    private List propertySources;
    private String version;
    private String state;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String[] getProfiles() {
        return profiles;
    }

    public void setProfiles(String[] profiles) {
        this.profiles = profiles;
    }

    public String getLabel() {
        return label;
    }

    public void setLabel(String label) {
        this.label = label;
    }

    public List getPropertySources() {
        return propertySources;
    }

    public void setPropertySources(List propertySources) {
        this.propertySources = propertySources;
    }

    public String getVersion() {
        return version;
    }

    public void setVersion(String version) {
        this.version = version;
    }

    public String getState() {
        return state;
    }

    public void setState(String state) {
        this.state = state;
    }

    public Environment() {

    }

    public Environment(String name, String[] profiles, String label, List propertySources, String version, String state) {

        this.name = name;
        this.profiles = profiles;
        this.label = label;
        this.propertySources = propertySources;
        this.version = version;
        this.state = state;
    }
}

PropertySource

import java.util.Map;

/**
 * @Auther: liyue
 * @Date: 2020/5/6 18:14
 * @Description:
 */
public class PropertySource {
    private String name;
    private Map source;

    public PropertySource() {
    }

    public PropertySource(String name, Map source) {
        this.name = name;
        this.source = source;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Map getSource() {
        return source;
    }

    public void setSource(Map source) {
        this.source = source;
    }
}

封装工具类 : ConfigWrapperUtil ; type是配置文件名,content是map类型,key是配置名称,value是配置值

import java.util.LinkedList;
import java.util.List;
import java.util.Map;

/**
 * @Auther: liyue
 * @Date: 2020/5/8 17:09
 * @Description:
 */
public class ConfigWrapperUtil {

    public static Environment wrapper(String type, Map content){
        Environment environment = new Environment();
        environment.setName("springbootService");
        environment.setLabel(null);
        String[] profiles = {type};
        environment.setProfiles(profiles);
        PropertySource propertySource = new PropertySource("http://127.0.0.1:10001/springbootService/"+type,content);
        List propertySources = new LinkedList(){{
            add(propertySource);
        }};
        environment.setPropertySources(propertySources);
        return environment;
    }
}

控制层 : SpringCloudConfigController

import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.Map;
import java.util.TreeMap;

/**
 * @Auther: liyue
 * @Date: 2020/5/8 17:05
 * @Description:
 */
@RestController
public class SpringCloudConfigController {


    @RequestMapping("/{springbootService}/{type}")
    public Object getMap(@PathVariable String type) {
        Map map = new TreeMap<>();
        map.put("server.port", "8002");
        map.put("name", "张三");
        return ConfigWrapperUtil.wrapper(type, map);
    }
}

 注 : springbootService 两边不加大括号的话,该名称必须和其他服务的 spring.application.name 配置的数值对应才能读取,两边加了大括号之后可以通用匹配,不需要管其他服务的 spring.application.name 配置内容

2.其他springboot服务读取配置

引入maven配置

        
            org.springframework.cloud
            spring-cloud-starter-config
            1.4.0.RELEASE
        

resources下新建 bootstrap.properties 文件,profile为接口的第二个URI,内容如下

spring.cloud.config.uri=http://localhost:10001/
spring.cloud.config.profile=server01

application.properties 中定义 spring.application.name,改数值必须与配置接口的第一个URI相同

spring.application.name=springCloudConfig
server.port=8001

 

3.调试

配置接口正常访问时,启动测试服务,若以8002端口运行说明成功,8001端口说明获取配置失败

 

 

 

END。
