ZK configuration center -- configuration and use of config Toolkit

Config Toolkit brief introduction ： Used in resource allocation center in distributed system , Instead of tradition properties file , advantage ： Modify the configuration immediately and take effect immediately , There is no need for a new repackaged deployment project .

Download address ：https://github.com/dangdangdotcom/config-toolkit

To configure zk, General configuration of production environment 5 platform , The configuration node is synchronized when it is created , Here, the default configuration is used , start-up zkServer.

Start project （ take config-face Pack it up jar perhaps war Deploy to server , at will ）：

Input http://localhost:8080 Enter the login page ：

Create node and password , Default The root node password is used sha1 encryption , Create password method ,( password :abc)：

[[email protected] ~]# python -c "import hashlib;print hashlib.sha1('abc').hexdigest();"

Create nodes ：

1. Use zk client

create /projectx 1

create /projectx/modulex a9993e364706816aba3e25717850c26c9cd0d89d

2. Use java Code

<dependency>
   <groupId>com.101tec</groupId>
   <artifactId>zkclient</artifactId>
   <version>0.10</version>
</dependency>

import org.I0Itec.zkclient.ZkClient;
import org.apache.zookeeper.CreateMode;

/**
 * Created by yz on 2018/6/11.
 */
public class TestZookeeper {
    public static void main(String[] args) {
        // 60000 session Timeout time ;1000  Connection timeout 
        ZkClient zkClient = new ZkClient("127.0.0.1:2181", 60000, 10000);
        //  node （ route ）; value ; Node type  PERSISTENT Permanent nodes 
        //zkClient.create("/projectx","1", CreateMode.PERSISTENT);
        zkClient.create("/projectx/modulex","a9993e364706816aba3e25717850c26c9cd0d89d", CreateMode.PERSISTENT);
        zkClient.close();
        System.out.println("### Registered successfully ###");
    }
}

Use the node name ：“/projectx/modulex”, password ：“abc” Sign in , After logging in , Click on new Create version 1.0.0

Create groups separately , Create nodes

Use configuration ：

1. The code gets the configuration directly ：

import com.dangdang.config.service.GeneralConfigGroup;
import com.dangdang.config.service.zookeeper.ZookeeperConfigGroup;
import com.dangdang.config.service.zookeeper.ZookeeperConfigProfile;

/**
 * @description:
 * @author: yz
 * @create: 2019/2/14 15:17
 */
public class YzDemo {

    public static void main(String[] args) {
        ZookeeperConfigProfile configProfile = new ZookeeperConfigProfile("localhost:2181", "/projectx/modulex", "1.0.0");
        GeneralConfigGroup group = new ZookeeperConfigGroup(configProfile, "group");

        String stringProperty = group.get("config.str");
        System.out.println("stringProperty: "+stringProperty);
        String intProperty = group.get("config.int");
        System.out.println("intProperty: "+intProperty);
    }

}

2.spring Injection allocation

<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">

<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>

</beans>
