etcd
etcd是一個(gè)分布式鍵值存儲(chǔ)數(shù)據(jù)庫(kù),用于共享配置和服務(wù)發(fā)現(xiàn)。
它是由CoreOS團(tuán)隊(duì)開(kāi)發(fā)并開(kāi)源的,具備以下特點(diǎn):簡(jiǎn)單、安全、高性能、一致可靠等 。etcd采用Go語(yǔ)言編寫(xiě),具有出色的跨平臺(tái)支持,很小的二進(jìn)制文件和強(qiáng)大的社區(qū)。etcd機(jī)器之間的通信通過(guò)Raft算法處理。文章來(lái)源:http://www.zghlxwxcb.cn/news/detail-668862.html
Spring Boot集成etcd
Spring Boot可以通過(guò)Jetcd Client來(lái)集成Etcd。Jetcd Client是一個(gè)Java庫(kù),用于與Etcd通信。你可以在Spring Boot應(yīng)用程序中使用它來(lái)讀寫(xiě)Etcd數(shù)據(jù)。以下是一些步驟:文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-668862.html
- 添加依賴(lài)項(xiàng):在你的pom.xml文件中添加以下依賴(lài)項(xiàng):
<dependency>
<groupId>io.etcd</groupId>
<artifactId>jetcd-core</artifactId>
<version>0.5.0</version>
</dependency>
- 配置Etcd客戶(hù)端:在你的Spring Boot應(yīng)用程序中配置Etcd客戶(hù)端。例如:
import io.etcd.jetcd.Client;
import io.etcd.jetcd.KV;
import io.etcd.jetcd.ByteSequence;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class EtcdConfig {
@Value("${etcd.endpoints}")
private String endpoints;
@Bean
public Client client() {
return JetcdClient.builder().endpoints(endpoints).build();
}
}
- 讀取和寫(xiě)入Etcd數(shù)據(jù):你可以使用Jetcd Client來(lái)讀取和寫(xiě)入Etcd數(shù)據(jù)。例如:
import io.etcd.jetcd.ByteSequence;
import io.etcd.jetcd.kv.GetResponse;
import io.etcd.jetcd.options.GetOption;
import io.etcd.jetcd.options.PutOption;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class EtcdService {
@Autowired
private Client client;
public void put(String key, String value) throws Exception {
PutOption option = PutOption.newBuilder().withLeaseId(ByteSequence.from(System.currentTimeMillis())).build();
KV kvClient = client.getKVClient();
kvClient.put(ByteSequence.from(key), ByteSequence.from(value), option);
}
public String get(String key) throws Exception {
GetResponse response = client.getKVClient().get(ByteSequence.from(key), GetOption.DEFAULT).get();
return response == null ? null : new String(response.getKvs().get(0).getKey(), response.getKvs().get(0).getValue().getRange());
}
}
