第二部分，对insert和update进行测试：
1 环境准备
分别准备了Insert和Update两种场景，其中，对于Update场景，还准备了通过索引更新和不走索引更新两种情况。
1.1 Update
代码如下：
package com.dhb.gts.javacourse.week6.mysqltest;
import com.dhb.gts.javacourse.fluent.dao.intf.OrderSummaryDao;
import com.dhb.gts.javacourse.fluent.entity.OrderSummaryEntity;
import com.google.common.base.Stopwatch;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.Random;
@RestController
@Slf4j
public class UpdateOrderTable {
@Autowired
OrderSummaryDao orderSummaryDao;
@RequestMapping("/randomOneModifyByKey")
public String randomModifyByKey() {
Stopwatch stopwatch = Stopwatch.createStarted();
Random random = new Random(System.currentTimeMillis());
// int maxOrderId = orderSummaryDao.selectMaxOrderId();
// int orderId = maxOrderId;
// if(maxOrderId > 50000) {
// orderId = random.nextInt(maxOrderId-50000)+50000;
// }else {
// orderId = random.nextInt(maxOrderId);
// }
int orderId = random.nextInt(2100000-50000)+50000;
OrderSummaryEntity where = new OrderSummaryEntity()
.setOrderId(orderId);
OrderSummaryEntity update = new OrderSummaryEntity()
.setConsigneeAddress("北京市丰台区方庄南路19号")
.setPaymentMethod(2);
orderSummaryDao.updateBy(update,where);
stopwatch.stop();
System.out.println("通过key修改 key is["+where.getOrderId()+"] cost is ：" + stopwatch);
return "success";
}
@RequestMapping("/randomOneModifyByNo")
public String randomOneModifyByNo() {
Stopwatch stopwatch = Stopwatch.createStarted();
Random random = new Random(System.currentTimeMillis());
// int maxOrderNo = orderSummaryDao.selectMaxOrderNo();
// int orderNo = maxOrderNo;
// if(maxOrderNo > 10000) {
// orderNo = random.nextInt(maxOrderNo-10000)+5000;
// }else {
// orderNo = random.nextInt(maxOrderNo);
// }
int orderNo = random.nextInt(1998425-50000)+50000;
OrderSummaryEntity where = new OrderSummaryEntity()
.setOrderNo(orderNo);
OrderSummaryEntity update = new OrderSummaryEntity()
.setConsigneeAddress("北京市丰台区方庄南路19号")
.setPaymentMethod(2);
orderSummaryDao.updateBy(update,where);
stopwatch.stop();
System.out.println("通过key修改 orderNo is["+where.getOrderNo()+"] cost is ：" + stopwatch);
return "success";
}
}
复制代码虽然提供了两个方法，一个走索引，一个走全表扫描。但是经过验证，全表扫描耗时特别长，大概5秒左右。因此通过全表扫描的方法来进行负载测试的话已经没有意义。
1.2 Insert
insert方法：
@RequestMapping("/randomInsertOneOrder")
public String randomInsertOneOrder() {
Stopwatch stopwatch = Stopwatch.createStarted();
int orderNo = getMaxOderNo();
insertOrder(orderNo+1);
log.info("randomInsertOneOrder cost time :"+ stopwatch.stop());
return "success";
}
复制代码利用之前提供的批次插入类中的方法，随机插入一行数据。

复制代码6.总结
将上述测试结果汇总
6.1 update
| 并发数 | DBCP | C3P0 | Druid | Hikari |
|---|---|---|---|---|
| 2C | 195.6R/S | 216.1R/S | 217.5R/S | 214.1R/S |
| 5C | 314.3R/S | 325.5R/S | 353.2R/S | 344.2R/S |
| 10C | 419.5R/S | 458.4R/S | 424.1R/S | 493.7R/S |
| 20C | 406.7R/S | 557.2R/S | 442.9R/S | 490.6R/S |
可以发现，C3P0的随机update性能是最好的，DBCP的随机UPDATE性能最差。而Hikari会优于Druid。 C3P0 > Hikari >= Druid > DBCP。
6.2 insert
| 并发数 | DBCP | C3P0 | Druid | Hikari |
|---|---|---|---|---|
| 2C | 99.9R/S | 119.4R/S | 118.1R/S | 129.3R/S |
| 5C | 184.2R/S | 230.3R/S | 231.3R/S | 228.1R/S |
| 10C | 254.3R/S | 347.8R/S | 309.6R/S | 340.4R/S |
| 20C | 263.5R/S | 458.8R/S | 333.7R/S | 345.1R/S |
可以发现，C3P0的随机insert与Hikari大致相同，DBCP的Insert性能最差。Druid优于DBCP。 C3P0 >= Hikari > Druid > DBCP。
6.3 select
回顾之前的select部分的测试结果。
| 测试次数 | DBCP | C3P0 | Druid | Hikari |
|---|---|---|---|---|
| 5c | 1908.2 R/S | 2901.6 R/S | 2865.2 R/S | 3030.2 R/S |
| 10c | 2482.5 R/S | 3580.4 R/s | 3481.4 R/S | 3680.4 R/S |
| 20c | 2504.4 R/S | 3192 R/S | 3322.7 R/S | 3276.1 R/S |
| 30c | 2288.4 R/S | 2905.8 R/S | 2964.6 R/S | 3106.4 R/S |
Hikari > Druid >= C3P0 > DBCP。
6.4 总结
将上述三个场景的测试结果汇总。可以发现： Hikari的select性能是最好的，再随机update方面弱于C3P0,insert方面与C3P0几乎相同。因此也可以理解为什么springboot中缺省的连接池是Hikari。 Druid 表现比较均衡，居于中上水平，在select、insert、update三方面都属于中上等，考虑到Druid还有丰富的监控功能，因此也是值得在生产环境使用的。 C3P0 虽然其查询select性能与Druid持平，但是在update随机修改场景具有最好的性能。insert场景也不弱。因此在合适的场景也是值得使用的。 DBCP 目前看来这个连接池在三个维度上对比都居于劣势，不知道还有没有其他优势场景没有测到。
