在集群运行的过程中,难以对整体的配置进行修改

 

所以集群的配置修改,在统一的位置中进行修改是普遍手段

 

在springcloud中,使用配置中心进行管理

 

一、配置

 

1.获取pom

 

 

使用svn的方式,还需要svnkit的pom

 

完整pom代码如下

 

<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">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.7.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>

    <groupId>com.lyh</groupId>
    <artifactId>lyh-config</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>lyh-config</name>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.8</java.version>
        <!-- SR2会报错,未解决 -->
        <spring-cloud.version>Greenwich.SR1</spring-cloud.version>
    </properties>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

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

        <!-- svn的客户端lib -->
        <dependency>
            <groupId>org.tmatesoft.svnkit</groupId>
            <artifactId>svnkit</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

 

2.创建maven项目并引入pom

  略

 

3.配置svn地址相关

 

yarm的配置,文件名为bootstrap.yml,而并非application.yml

 

server:
  port: 9000
spring:
  application:
    name: config-server
  profiles:#必须指定为svn,否则默认访问git
    active: subversion
  cloud:
    config:
      server:
        svn:
          uri: https://47.105.121.158/svn/liuyuhang_FM/configCenter/#svn要访问的最终文件夹地址
          username: liuyuhang
          password: *********
          search-paths: #这一项应该有,允空
          default-label: testConfig
      basedir: /data #临时文件夹,防清空

 

svn的update地址,对应关系如下:

 

包含文件如下:

 

 二、创建启动类

 

1.创建启动类并添加注解@EnableConfigServer,代码如下:

 

package com.lyh.lyh_eureka_server;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.config.server.EnableConfigServer;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.hystrix.EnableHystrix;
import org.springframework.cloud.openfeign.EnableFeignClients;

@SpringBootApplication
@EnableConfigServer
public class ConfigRun {

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

}

 

三.测试

 

注意访问地址和svn配置相关的对应关系

 

访问地址,dev下地址和结果

 访问具体文件的地址和结果

 

以上!
