百度DisConf-分布式配置管理平台使用

1.1 场景介绍

模拟数据库配置文件db.properties从disconf 获取：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/shiro?characterEncoding=utf-8
jdbc.username=k2mwfNyZL/M=
jdbc.password=k2mwfNyZL/M=

1.1 导入所需的jar包

<dependency>
    <groupId>com.baidu.disconf</groupId>
    <artifactId>disconf-client</artifactId>
    <version>2.6.36</version>
</dependency>
<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.5</version>
</dependency>
<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpcore</artifactId>
    <version>4.4.9</version>
</dependency>

1.2 在disconf-web端上传db.properties内容

1、新建APP


2、新建配置文件

1.3 项目的配置

1、在src/main/resources下创建disconf.properties文件

    # 是否使用远程配置文件
    # true(默认)会从远程获取配置 false则直接获取本地配置
    enable.remote.conf=true

    #
    # 配置服务器的 HOST,用逗号分隔  127.0.0.1:8000,127.0.0.1:8000
    #
    conf_server_host=http://localhost

    # 版本, 请采用 X_X_X_X 格式
     version=1

    # APP 请采用 产品线_服务名 格式
    app=ssm-web

    # 环境
    env=local

    # debug
    debug=true

    # 忽略哪些分布式配置，用逗号分隔
    ignore=

    # 获取远程配置 重试次数，默认是3次
    conf_server_url_retry_times=1
    # 获取远程配置 重试时休眠时间，默认是5秒
    conf_server_url_retry_sleep_seconds=1

2、创建applicationContext-disconf.xml文件
