Spring Cloud Config 本地配置

七：Spring Cloud Config 本地配置

本地文件系统

我们可以将微服务的相关配置文件存储到本地文件中，然后让微服务来读取本地文件。

创建本地文件 Config Server

1.创建模块，配置环境

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>springCloud01</artifactId>
        <groupId>org.example</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>nativeConfigServer</artifactId>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-server</artifactId>
        </dependency>
    </dependencies>

</project>

2.配置application.yml

server:
  port: 8762
spring:
  application:
    name: nativeconfigserver
 profiles:
   active: native
  cloud:
    config:
      server:
        native:
          search-location: classpath:/shared

3.创建文件夹shared、文件configclient-dev.yml

server:
  port: 8070
foo: foo version 1

4.编写启动类

package com.southwind;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;

@SpringBootApplication
@EnableConfigServer
public class nativeServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(nativeServerApplication.class,args);
    }
}

配置中心已经完成

创建客户端

1.创建模块，配置环境

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>springCloud01</artifactId>
        <groupId>org.example</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>nativeconfigclient</artifactId>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>
    </dependencies>

</project>

2.创建文件

bootstrap.yml

spring:
  application:
    name: configclient
  profiles:
    active: dev
  cloud:
    config:
      uri: http://localhost:8762
      fail-fast: true

3启动类：

package com.southwind;

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

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

4.handler：

package com.southwind.controller;

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

@RestController
@RequestMapping("/native")
public class NativeConfigHandler {
    @Value("${server.port}")
    private String port;
    @Value("${foo}")
    private String foo;
    @GetMapping("/index")
    public String index(){
        return this.port+"---"+this.foo;
    }
}
