A, JMeter entry
Download Link http://jmeter.apache.org/download_jmeter.cgi
Adding a thread group
Http request to set default values
http request to add pressure to be measured
Add Aggregate Report listener
Start the test
1000 threads, 10 cycles, i.e., 10,000 requests
Two, redis pressure measurement
1. redis-benchmark -h 127.0.0.1 -p 6379 -c 100 -n 100000
Concurrent connections 100, 100 000 requests
2. redis-benchmark -h 127.0.0.1 -p 6379 -q -d 100
100 bytes
3. redis-benchmark -t set,lpush -q -n 100000
4.redis-benchmark -n 100000 -q script load "redis.call('set','foo','set')"
Three, SpringBoot fight the war package
pom add dependencies
<!-- provided表示 编译时依赖 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<build>
<finalName>${project.artifactId}</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
</build>
启动类gen更改如下：
package com.wings.seckill;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
@SpringBootApplication
public class MainApplication extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(MainApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(MainApplication.class);
}
}
三、JMeter命令行
总体思路：
1.在windows上录好jmx;
2.命令行：sh jmeter.sh -n -t XXX.jmx -l result.jtl
3.把result.jtl导入到jmeter
pom文件去掉war包相关依赖及插件，添加以下插件
<build>
<finalName>${project.artifactId}</finalName>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
入口类改回最清爽模式
package com.wings.seckill;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
@SpringBootApplication
public class MainApplication{
public static void main(String[] args) {
SpringApplication.run(MainApplication.class, args);
}
}
批量新增用户相关辅助类

Class.forName(driver);

System.out.println("create user");

public static void main(String[] args) throws Exception {
createUser(5000);

}
JMeter添加CSV文件
优化前结果：
1000 * 10
QPS：109
出现超卖现象：
