不同的数据库连接池(DBCP,C3P0,Druid,Hikari)下对mysql的insert和select性能对比

2021-09-22 10:58:27 浏览数 (2)

分别测试4中连接池（DBCP、C3P0、Druid、Hikari）的表现情况。

1.环境准备

1.1 连接池配置

1.1.1 DBCP

gradle导入包；

代码语言：javascript复制
implementation 'org.apache.commons:commons-dbcp2:2.9.0'

application.yml配置：

代码语言：javascript复制
# DBCP
spring.datasource.url: jdbc:mysql://192.168.162.49:3306/gts?useSSL=false&autoReconnect=true&characterEncoding=UTF-8
spring.datasource.username: gts
spring.datasource.password: mysql
spring.datasource.driver-class-name: com.mysql.cj.jdbc.Driver
spring.datasource.type: org.apache.commons.dbcp2.BasicDataSource

需要指定spring.datasource.type。

1.1.2 C3P0

gradle导入包:

代码语言：javascript复制
implementation 'com.mchange:c3p0:0.9.5.5'

application.yml配置：

代码语言：javascript复制
## C3P0
spring.datasource.jdbcUrl: jdbc:mysql://192.168.162.49:3306/gts?useSSL=false&autoReconnect=true&characterEncoding=UTF-8&serverTimezone=UTC
spring.datasource.user: gts
spring.datasource.password: mysql
spring.datasource.driverClass: com.mysql.cj.jdbc.Driver
spring.datasource.type: com.mchange.v2.c3p0.ComboPooledDataSource

需要指定spring.datasource.type。 C3P0不能直接复用springDataSource的默认配置，需要单独指定一个类：

代码语言：javascript复制
package com.dhb.gts.javacourse.week6.mysqltest;

import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;

@Configuration
public class C3p0DatasourceConfig {

	@Bean(name = "dataSource")
	@Qualifier(value = "dataSource")
	@ConfigurationProperties(prefix = "spring.datasource")
	public DataSource dataSource() {
		       return DataSourceBuilder.create().type(com.mchange.v2.c3p0.ComboPooledDataSource.class).build();
	}
	
}

1.1.3 Druid

gradle导入包：

代码语言：javascript复制
implementation 'com.alibaba:druid:1.2.6'

application.yml配置：

代码语言：javascript复制
# 数据源配置 durid
spring.datasource.url: jdbc:mysql://192.168.162.49:3306/gts?useSSL=false&autoReconnect=true&characterEncoding=UTF-8
spring.datasource.username: gts
spring.datasource.password: mysql
spring.datasource.driver-class-name: com.mysql.cj.jdbc.Driver
spring.datasource.type: com.alibaba.druid.pool.DruidDataSource

需要指定spring.datasource.type。

1.1.4 Hikari

gradle导入包：

代码语言：javascript复制
implementation 'com.zaxxer:HikariCP:4.0.3'

由于Hikari是springboot中 tomcat的默认连接池，因此无需指定type。

代码语言：javascript复制
#数据源配置 默认Hikari
spring.datasource.url: jdbc:mysql://192.168.162.49:3306/gts?useSSL=false&autoReconnect=true&characterEncoding=UTF-8
spring.datasource.username: gts
spring.datasource.password: mysql
spring.datasource.driver-class-name: com.mysql.cj.jdbc.Driver

1.1.5 通用配置

代码语言：javascript复制
spring.datasource.initialSize: 5
spring.datasource.minIdle: 5
spring.datasource.maxActive: 20
spring.datasource.maxWait: 60000
spring.datasource.timeBetweenEvictionRunsMillis: 60000
spring.datasource.validationQuery: SELECT 1
spring.datasource.testWhileIdle: true
spring.datasource.testOnBorrow: false
spring.datasource.testOnReturn: false
spring.datasource.poolPreparedStatements: true
spring.datasource.maxPoolPreparedStatementPerConnectionSize: 20
spring.datasource.filters: stat

1.2 测试的API

订单查询类:

代码语言：javascript复制
package com.dhb.gts.javacourse.week6.mysqltest;

import com.alibaba.fastjson.JSON;
import com.dhb.gts.javacourse.fluent.dao.intf.OrderSummaryDao;
import com.dhb.gts.javacourse.fluent.entity.OrderSummaryEntity;
import com.dhb.gts.javacourse.fluent.helper.OrderSummaryMapping;
import com.dhb.gts.javacourse.fluent.mapper.OrderDetailMapper;
import com.dhb.gts.javacourse.fluent.mapper.OrderSummaryMapper;
import com.google.common.base.Stopwatch;
import lombok.extern.slf4j.Slf4j;
import org.apache.logging.log4j.util.Strings;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

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

@RestController
@Slf4j
public class QueryOrderTable {
	
	@Autowired
	OrderSummaryDao orderSummaryDao;

	@RequestMapping("/queryByKey")
	public String queryByKey(String key) {
		Stopwatch stopwatch = Stopwatch.createStarted();
		Integer orde_id = Integer.parseInt(key);
		OrderSummaryEntity entity = orderSummaryDao.selectById(orde_id);
		stopwatch.stop();
		System.out.println("通过key查询，走索引耗时："   stopwatch);
		return JSON.toJSONString(entity);
	}

	@RequestMapping("/queryByOther")
	public String queryByKey(String orderNo, String expressNo) {
		Stopwatch stopwatch = Stopwatch.createStarted();
		Map<String, Object> map = new HashMap<>();
		if (Strings.isNotEmpty(orderNo)) {
			Integer order_no = Integer.parseInt(orderNo);
			map.put(OrderSummaryMapping.orderNo.column, order_no);
		} else if (Strings.isNotEmpty(expressNo)) {
			map.put(OrderSummaryMapping.expressNo.column, expressNo);
		}
		List<OrderSummaryEntity> entitys = orderSummaryDao.selectByMap(map);
		stopwatch.stop();
		System.out.println("不通过key查询，全表扫描耗时："   stopwatch);
		return JSON.toJSONString(entitys);
	}
}

1.3 测试工具

结论，如果不通过索引，全表扫描的话，在100万级数据量上进行全表扫描的时间将是通过索引时间的1000倍，这个时间达到了3秒左右。 需要注意的是，上述的测试每次都是测试的不同数据，以避免mysql数据库的缓存。

5 采用apachebench 进行负载测试

由于前面每个场景的测试过程中，通过主键的查询效率最高，另外由于mysql在第二次查询的时候，会对数据进行缓存，那么现在可以通过apachebench查询同一条数据，这条数据的性能在走缓存之后， 查询效率是最高的，通过这种方式来对4种连接池进行负载测试，测试结果的差异，就大致可以认为是4种连接池的差异了。 4种连接池的通用配置参数都相同。

3106.4 R/S

结论： 可以通过上述测试结果发现，Hikari > Druid > C3P0 > DBCP。 实际上Druid与C3P0差距不大。但是Druid具有良好的可监控性，比C3P0更值得推荐。DBCP是表现最差的。
