這篇文章主要為大家詳細介紹了SpringBoot整合clickhouse配置多分片地址的相關方法,文中的示例代碼講解詳細,感興趣的小伙伴可以跟隨小編一起學習一下

其實通常CK集群是要配置負載均衡地址的，但是如果不行，那么就需要配置集群具體分片地址。

pom文件配置

<dependency>
     <groupId>com.alibaba</groupId>
     <artifactId>druid-spring-boot-starter</artifactId>
     <version>1.2.20</version> <!-- 推薦 1.2.8+ -->
 </dependency>

 <dependency>
     <groupId>com.clickhouse</groupId>
     <artifactId>clickhouse-jdbc</artifactId>
     <version>0.3.2-patch11</version>
 </dependency>

 <!-- 添加 LZ4 依賴 -->
 <dependency>
     <groupId>org.lz4</groupId>
     <artifactId>lz4-java</artifactId>
     <version>1.8.0</version>
 </dependency>

yml配置：

  clickhouse:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.alibaba.druid.support.clickhouse.BalancedClickhouseDriver
    url: jdbc:clickhouse://ip:port,ip:port..../database
    username: root
    password: 123456
    druid:
      initial-size: 5
      min-idle: 5
      max-active: 20
      max-wait: 60000
      time-between-eviction-runs-millis: 60000
      min-evictable-idle-time-millis: 300000
      test-while-idle: true
      test-on-borrow: false
      test-on-return: false
