Spring Cloud （1）——config server使用SVN作为远程例子的运行与配置

 

官方链接与文档 写道

 

https://spring.io/guides/gs/centralized-configuration/

 

 

Spring cloud config Server基于Spring boot构建，

 

1. 建议下载使用官方的Eclipse （ sts-3.7.2.RELEASE）
2. 下载config server sample 的源码，并导入到eclipse工程中，gs-centralized-configuration-complete\configuration-service
3. 修改配置文件
4. 启动程序

配置文件 maven文件：

<?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"

 application.properties:

server.port=8888
spring.application.name=configServer
#spring.cloud.config.server.git.uri=${HOME}/Desktop/config
spring.profiles.active=subversion
spring.cloud.config.server.svn.uri=svn://IP:port/project/config
spring.cloud.config.server.svn.username=lvdccyb
spring.cloud.config.enabled=true
spring.cloud.config.server.svn.password=lvdccyb@126.com
spring.main.show-banner=false

 

其中这3项表面使用svn，并需要注意，远程url可用。

 

 

spring.profiles.active=subversion
spring.cloud.config.server.svn.uri=svn://IP:port/project/config
spring.cloud.config.server.svn.username=lvdccyb

 

 

 

运行结果（部分内容去掉）：

 

 

http://localhost:8888/env

 

{
    "profiles": [
        "subversion"
    ],
    "bootstrap": {},
    "servletContextInitParams": {},

    "configServerClient": {
        "spring.cloud.config.enabled": "false"
    },
    "applicationConfig: [classpath:/application.properties]": {
        "spring.cloud.config.server.svn.password": "******",
        "spring.cloud.config.server.svn.uri": "svn://X.Y.Z.U/project/config",
        "server.port": "8888",
        "spring.profiles.active": "subversion",
        "spring.main.show-banner": "false",
        "spring.cloud.config.enabled": "true",
        "spring.cloud.config.server.svn.username": "lvdccyb",
        "spring.application.name": "configServer"
    },
    "defaultProperties": {
        "spring.application.name": "bootstrap"
    }
}

http://localhost:8888/configuration-client/default

注意上面地址：对应的svn地址一般为：
svn://IP:PORT/{$配置的uri}/trunk/configuration-client.properties
而且这个地址，需要仔细阅读spring 官方文档对application，profile，label的解释，以及路径的寻找优先级，上述地址缺省配置时，可以写成多种多样：
http://localhost:8888/configuration-client/default/trunk
http://localhost:8888/configuration-client/trunk/trunk
http://localhost:8888/configuration-client/trunk
甚至如下：
http://localhost:8888/configuration-client/abc
这里需要多一级trunk目录，而不是直接使用配置文件。

{
    "name": "configuration-client",
    "profiles": [
        "default"
    ],
    "label": "trunk",
    "propertySources": [
        {
            "name": "svn://IP：PORT/{$配置的uri}/trunk/configuration-client.properties",
            "source": {
                "IamApplicationName": "true",
                "message": "Hello World,I am spring client"
            }
        }
    ]
}

—————————————————————————————————————————————

Config 客户端：

application.properties文件
#这个需要与配置文件对应起来
spring.application.name=configuration-client
spring.cloud.config.uri=http://localhost:8888
启动程序后，访问:

http://localhost:8080/message

可以看到：

Hello World,I am spring client

 

这个与前面SERVER端显示的内容一样，说明配置已经生效了。
