Springboot实现Clickhouse连接池的配置和接口查询

1、添加引用 pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

             </configuration>
          </plugin>
       </plugins>
    </build>
</project>

2、添加配置application.yml

spring:
  datasource:
    clickhouse:
      type: com.alibaba.druid.pool.DruidDataSource
      driver-class-name: ru.yandex.clickhouse.ClickHouseDriver
      url: jdbc:clickhouse://172.20.6.27:8123/hrlaser
      username: default
      password:
      initial-size: 5
      min-idle: 5
      max-active: 20
      max-wait: 60000
      time-between-eviction-runs-millis: 60000
      min-evictable-idle-time-millis: 300000
      validation-query: SELECT 1
      test-while-idle: true
      test-on-borrow: false
      test-on-return: false
      pool-prepared-statements: true
      max-pool-prepared-statement-per-connection-size: 20

#mybatis 配置
mybatis:
  type-aliases-package: com/hrlaser/clickhouse/bean
  config-location: classpath:mybatis-config.xml
  mapper-locations: classpath:mapper/*.xml

3、mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//my4batis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<!--mybatis的核心配置文件是有一定顺序的 -->
<configuration>

    <settings>
        <!-- 开启二级缓存-->
        <setting name="cacheEnabled" value="true"/>
    </settings>
</configuration>

4、DruidConfig.java

package com.hrlaser.clickhouse.utils;

import com.alibaba.druid.pool.DruidDataSource;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;

@Configuration
public class DruidConfig {

    @Value("${spring.datasource.clickhouse.driver-class-name}")
    private String driverClassName;

    @Value("${spring.datasource.clickhouse.url}")
    private String url;

    @Value("${spring.datasource.clickhouse.username}")
    private String username;

    @Value("${spring.datasource.clickhouse.password}")
    private String password;

    @Value("${spring.datasource.clickhouse.initial-size}")
    private int initialSize;

    @Value("${spring.datasource.clickhouse.min-idle}")
    private int minIdle;

    @Value("${spring.datasource.clickhouse.max-active}")
    private int maxActive;

    @Value("${spring.datasource.clickhouse.max-wait}")
    private int maxWait;

    @Value("${spring.datasource.clickhouse.time-between-eviction-runs-millis}")
    private int timeBetweenEvictionRunsMillis;

    @Value("${spring.datasource.clickhouse.min-evictable-idle-time-millis}")
    private int minEvictableIdleTimeMillis;

    @Value("${spring.datasource.clickhouse.validation-query}")
    private String validationQuery;

    @Value("${spring.datasource.clickhouse.test-while-idle}")
    private boolean testWhileIdle;

    @Value("${spring.datasource.clickhouse.test-on-borrow}")
    private boolean testOnBorrow;

    @Value("${spring.datasource.clickhouse.test-on-return}")
    private boolean testOnReturn;

    @Value("${spring.datasource.clickhouse.pool-prepared-statements}")
    private boolean poolPreparedStatements;

    @Value("${spring.datasource.clickhouse.max-pool-prepared-statement-per-connection-size}")
    private int maxPoolPreparedStatementPerConnectionSize;

    @Bean
    public DataSource clickhouseDataSource() {
        DruidDataSource dataSource = new DruidDataSource();
        dataSource.setDriverClassName(driverClassName);
        dataSource.setUrl(url);
        dataSource.setUsername(username);
        dataSource.setPassword(password);
        dataSource.setInitialSize(initialSize);
        dataSource.setMinIdle(minIdle);
        dataSource.setMaxActive(maxActive);
        dataSource.setMaxWait(maxWait);
        dataSource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);
        dataSource.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMillis);
        dataSource.setValidationQuery(validationQuery);
        dataSource.setTestWhileIdle(testWhileIdle);
        dataSource.setTestOnBorrow(testOnBorrow);
        dataSource.setTestOnReturn(testOnReturn);
        dataSource.setPoolPreparedStatements(poolPreparedStatements);
        dataSource.setMaxPoolPreparedStatementPerConnectionSize(maxPoolPreparedStatementPerConnectionSize);
        return dataSource;
    }
}

5、Mapper.class

package com.hrlaser.clickhouse.mapper;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;

import java.util.List;
import java.util.Map;

@Repository
public class DeviceWeldingTimeMapper {

    @Autowired
    private JdbcTemplate jdbcTemplate;

    public List<Map<String, Object>> queryData() {
        String sql = "SELECT * FROM device_welding_time";
        return jdbcTemplate.queryForList(sql);
    }

    public int save() {
        String sql = "  INSERT into device_welding_time VALUES('1999277069438382085','IHA000SOC00283', 1,'A3MD40','1858410823164407810',null,NULL,0)";
        jdbcTemplate.execute(sql);
        return 1;
    }
}

6、service.java

package com.hrlaser.clickhouse.service;

import com.hrlaser.clickhouse.bean.DeviceWeldingTime;

import java.util.List;
import java.util.Map;

public interface DeviceWeldingTimeService {
    List<Map<String, Object>> getClickHouseData();

    int save(DeviceWeldingTime deviceWeldingTime);
}

7、ServiceImpl.java

package com.hrlaser.clickhouse.service;

import com.hrlaser.clickhouse.bean.DeviceWeldingTime;
import com.hrlaser.clickhouse.mapper.DeviceWeldingTimeMapper;
import jakarta.annotation.Resource;
import org.springframework.stereotype.Service;

import java.util.List;
import java.util.Map;

@Service
public class DeviceWeldingTimeServiceImpl implements DeviceWeldingTimeService{
    @Resource
    private DeviceWeldingTimeMapper deviceWeldingTimeMapper;


    @Override
    public List<Map<String, Object>> getClickHouseData() {
        return deviceWeldingTimeMapper.queryData();
    }

    @Override
    public int save(DeviceWeldingTime deviceWeldingTime) {
        return deviceWeldingTimeMapper.save();
    }
}

9、controller

package com.hrlaser.clickhouse.controller;

import com.hrlaser.clickhouse.bean.DeviceWeldingTime;
import com.hrlaser.clickhouse.service.DeviceWeldingTimeServiceImpl;
import jakarta.annotation.Resource;
import lombok.extern.java.Log;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;
import java.util.Map;

/**
 * 设备焊接时长
 * @author zhanghao
 * @Date 2025-12-15
 */
@RestController
public class DeviceWeldingTimeController {

    @Resource
    private DeviceWeldingTimeServiceImpl deviceWeldingTimeService;

    @GetMapping("/clickhouse/data")
    public List<Map<String, Object>> getClickHouseData() {
        return deviceWeldingTimeService.getClickHouseData();
    }

    /**
     *注意：app或单片机直接访问的接口路径以dataOrigin开头----------所有与app或单片机交互的接口
     */

    //上传设备单次焊接时长数据

    @GetMapping("dataOrigin/save")
    @Deprecated
    public Integer saveData(){
        //根据项目名称获取项目ID
        return deviceWeldingTimeService.save(null);
    }

}

10、启动类

package com.hrlaser.clickhouse;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan("com.hrlaser.clickhouse.mapper")
public class ClickhouseApplication {

    public static void main(String[] args) {
       SpringApplication.run(ClickhouseApplication.class, args);
    }

}
