### 一、如何引入

```xml

    plus.jdk

    spring-boot-starter-etcd

    1.0.6

```

### 二、etcd的引用配置

```bash

plus.jdk.etcd.enabled=true

plus.jdk.etcd.user-name=admin

plus.jdk.etcd.password=123456

plus.jdk.etcd.endpoints=http://ip1:2379,http://ip2:2379,http://ip3:2379

```

> java 使用etcd不建议使用证书,因为`SslContext Builder`只支持PEM格式的[PKCS#8](https://github.com/etcd-io/jetcd/blob/main/docs/SslConfig.md)私钥文件。

### 三、在项目中引用

下面给出一个使用示例。

```java

import lombok.extern.slf4j.Slf4j;

import plus.jdk.etcd.annotation.EtcdNode;

import plus.jdk.etcd.global.EtcdClient;

import plus.jdk.scheduled.annotation.Scheduled;

import plus.jdk.scheduled.global.IScheduled;

import javax.annotation.Resource;

import java.lang.management.ManagementFactory;

import java.lang.management.OperatingSystemMXBean;

import java.util.ArrayList;

import java.util.Collections;

import java.util.List;

import java.util.Random;

import java.util.concurrent.ArrayBlockingQueue;

import java.util.concurrent.ThreadPoolExecutor;

import java.util.concurrent.TimeUnit;

@Slf4j

@Scheduled(expr = "0/1 * * * * *")

public class LoadAverageScheduledTask extends IScheduled {

    @EtcdNode(path = "/example/system/aim/loadAverage")

    private volatile double maxLoadAverage = 2.0;

    @EtcdNode(path = "/example/system/aim/random/length")

    private volatile int maxRandomLen = 500000;

    @Resource

    private EtcdClient etcdClient;

    private final ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(5, 200,

            0, TimeUnit.SECONDS,

            new ArrayBlockingQueue<>(200));

    @Override

    protected void doInCronJob() {

        String data = etcdClient.getFirstKV("/example", String.class);

    }

}

```
