搭建配置界面
下载config-toolkit项目
git clone https://github.com/dangdangdotcom/config-toolkit.git
cd config-toolkit/config-zk-web
mvn package
将编译好的config-web.war部署到tomcat即可
创建初始权限配置
使用命令行创建zookeeper配置根节点,根节点密码使用sha1加密,如果要使用明文密码,可以自行修改config-zk-web的鉴权部分代码
以根路径为/projectx/modulex
密码为abc
为例
python -c "import hashlib;print hashlib.sha1('abc').hexdigest();"
# a9993e364706816aba3e25717850c26c9cd0d89d
zkCli.sh -server localhost:2181
create /projectx 1
create /projectx/modulex a9993e364706816aba3e25717850c26c9cd0d89d
登录config-web,创建示例配置
- 访问http://localhost:8080/config-web
- 点击"切换根节点",输入/projectx/modulex,密码abc
- 点击"新建版本",输入1.0.0
- 左侧的组管理,输入group,点击"创建"
- 在右侧添加两个配置,分别为config.str=hello, config.int=7758
项目中加载配置
添加maven依赖
<dependency>
<groupId>com.dangdang</groupId>
<artifactId>config-toolkit</artifactId>
<version>3.2.4-RELEASE</version>
</dependency>
使用Java代码直接获取配置
ZookeeperConfigProfile configProfile = new ZookeeperConfigProfile("localhost:2181", "/projectx/modulex", "1.0.0");
GeneralConfigGroup group = new ZookeeperConfigGroup(configProfile, "group");
String stringProperty = group.get("config.str");
Preconditions.checkState("hello".equals(stringProperty));
String intProperty = group.get("config.int");
Preconditions.checkState(7758 == Integer.parseInt(intProperty));
结合spring placeholder方式注入配置
spring xml schema
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:config="https://crnlmchina.github.io/config"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
https://crnlmchina.github.io/config https://crnlmchina.github.io/config/config.xsd">
bean配置
<config:profile connect-str="localhost:2181" root-node="/projectx/modulex"
version="1.0.0"/>
<config:placeholder>
<config:group node="property-group1" />
<config:group node="property-group2" />
</config:placeholder>
<!-- Your business bean -->
<bean class="your.BusinessBean">
<property name="strProp" value="${config.str}" />
<property name="intProp" value="${config.int}" />
</bean>
由于spring对多个placeholder的支持不太好,需要仔细配置order,所以建议使用SPEL方式来配置
结合spring SPEL方式注入配置
<config:profile connect-str="localhost:2181" root-node="/projectx/modulex" version="1.0.0"/>
<config:group id="groupProp" node="group"/>
<!-- Your business bean -->
<bean class="your.BusinessBean">
<property name="strProp" value="#{groupProp['config.str']}" />
<property name="intProp" value="#{groupProp['config.int']}" />
</bean>
