连接数据库

填写配置信息

数据库不填则可查看所有数据库

新建数据库

CREATE DATABASE IF NOT EXISTS sbfzl;

新建表的代码后面要自己加上;

CREATE TABLE sbfzl.t_user (
	id VARCHAR(20),
	username VARCHAR(50),
	password VARCHAR(50)
);;

集成springboot

<dependency>
    <groupId>ru.yandex.clickhouse</groupId>
    <artifactId>clickhouse-jdbc</artifactId>
    <version>0.2.4</version>
</dependency>

clickhouse没有主键，手动添加主键注解

@TableName(value ="t_user")
@Data
public class TUser implements Serializable {

    @TableId(value = "id", type = IdType.ASSIGN_UUID)
    private String id;
}
