关于springmvc的helloworld的压测报告
都说hello world 很简单，应该能承受很大的请求压力，那么到底有多大？你知道吗？如果知道，那咱们就不继续了。如果不知道，我们来看一下！
1. 准备工作，快速建立一个基于springmvc的helloworld
1.1. 在pom.xml引入spring必须的包级日志组件

1.2. 添加一个 web.xml, 只加一个dispatcherServlet 和一个字符集转换过滤器
<filter> <filter-name>SpringEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>SpringEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 防止Spring内存溢出监听器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- 如下 listener 会查找 WEB-INF/applicationContext.xml 文件 --> <!--<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>--> <!-- springMVC核心配置 --> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 拦截设置 --> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.jsp</welcome-file> </welcome-file-list>
1.3. 添加log4j.properties日志配置文件
log4j.rootLogger=DEBUG,console,im,logFile log4j.additivity.org.apache=true # 控制台(console) log4j.appender.console=org.apache.log4j.ConsoleAppender log4j.appender.console.Threshold=DEBUG log4j.appender.console.ImmediateFlush=true log4j.appender.console.Target=System.out log4j.appender.console.layout=org.apache.log4j.PatternLayout log4j.appender.console.layout.ConversionPattern=%d(%r) [%t] %-5p %l: %m %x %n # 日志文件(logFile) log4j.appender.logFile=org.apache.log4j.FileAppender log4j.appender.logFile.Threshold=DEBUG log4j.appender.logFile.ImmediateFlush=true log4j.appender.logFile.Append=true log4j.appender.logFile.File=D:/logs/log.log4j log4j.appender.logFile.layout=org.apache.log4j.PatternLayout log4j.appender.logFile.layout.ConversionPattern=%d(%r) [%t] %-5p %l: %m %x %n # 回滚文件(rollingFile) log4j.appender.rollingFile=org.apache.log4j.RollingFileAppender log4j.appender.rollingFile.Threshold=DEBUG log4j.appender.rollingFile.ImmediateFlush=true log4j.appender.rollingFile.Append=true log4j.appender.rollingFile.File=D:/logs/log.log4j log4j.appender.rollingFile.MaxFileSize=200KB log4j.appender.rollingFile.MaxBackupIndex=50 log4j.appender.rollingFile.layout=org.apache.log4j.PatternLayout log4j.appender.rollingFile.layout.ConversionPattern=%d(%r) [%t] %-5p %l: %m %x %n
1.4. 添加一个HelloController, 返回一个 字符串
@RestController @RequestMapping("/hello") public class HelloController { @RequestMapping(value = "/world", method = {RequestMethod.GET, RequestMethod.POST}, produces = "application/json") @ResponseBody public Object world(@ModelAttribute UserInfo info) { return "hello world!"; } }
好了，一切准备就绪！是时候让我们来看一下它的能力如何了！
测试工具： jmeter + 台式测试机一台
前提1:
机器配置: 4c8g 笔记本
网卡: 高通 QCA9377, 共享带宽: 100M, 网络测速: 下载:3.5MB/s 上传:475KB/s
web容器: tomcat7, 运行模式: apr(apache portable runtime)
压测过程如下:
并发100-5组连续请求, TPS: 146.2, error: 0, 平均响应时间: 0.381s, 最大响应时间: 2.44s
server端cpu有一瞬间的飙高，内存几乎无变化！
下面，按照规律，翻倍并发，200-5组连续请求！看下数据！
TPS增加了，为275；平均响应时间慢了点，0.429；没有 error。
再翻倍并发量：400-5组连续请求：
TPS下降了，为208；平均响应时间翻番，1.1秒；不过幸好还是没有error；
再翻倍并发量：800-5组连续请求：
TPS再次下降，为144；平均响应时间再翻番，3.6秒，这在生产环境已经不符合要求了！error仍为0；
再翻倍： 1600-5组： server cpu 一直高居不下，直接jvm宕机。
注意，此时已经有error出现了，1.09%的错误率！ TPS继续下降： 93.4，平均响应时间继续翻倍：8.9秒；
综上，springmvc的helloworld 能力差不多也就在1600了，因为已经有错误出现，在实际生产中已经完全不能接受了！
不过，我还是想看一下server到底能承受多大压力，也就是jvm完全宕机！
压到3000并发-5组：
看起来还能响应，其实再server端，jvm已经挂掉了！所以结论是，tomcat7（apr模式）是扛不住3000并发的！
jvm 宕机日志样例如下：

其中，也指示了错误记录文件：hs_err_pid13444.log，其中大概是一些线程、栈、内存、cpu的总结内容！
大概就是说，

降到2800，也依然jvm挂了！
降到2600，jvm没挂，但是错误量较多，由于错误导致并发只跑到12000就未能继续进行了，数据不准：
改了下失败策略后，2600，还是挂了，重启后可以扛住压力！
压到4840个请求就挂了！
2500并发，挂！
2300并发，挂！
2200并发，操作系统提示jre没有响应，被迫关闭java进程！
2000并发，挂！
1900并发，扛住了！cpu在80左右跳动！内存不变！
看来，1900还行，极限就2000吧！
好了，tomcat7看来是没辙了！
换tomcat8 的 nio 看下效果！
前提2：
tomcat8, nio 模式运行！
NIO介绍如下：
Java NIO: Channels and Buffers（通道和缓冲区）
标准的IO基于字节流和字符流进行操作的，而NIO是基于通道（Channel）和缓冲区（Buffer）进行操作，数据总是从通道读取到缓冲区中，或者从缓冲区写入到通道中。
Java NIO: Non-blocking IO（非阻塞IO）
Java NIO可以让你非阻塞的使用IO，例如：当线程从通道读取数据到缓冲区时，线程还是可以进行其他事情。当数据被写入到缓冲区时，线程可以继续处理它。从缓冲区写入通道也类似。
Java NIO: Selectors（选择器）
Java NIO引入了选择器的概念，选择器用于监听多个通道的事件（比如：连接打开，数据到达）。因此，单个的线程可以监听多个数据通道。
直接从2000并发开测！
并发2000-5组连续请求！
server ok, 但是，仍然存在数错误，有几个并发请求卡死！ TPS: 62.9, 平均响应: 14.7s。
server 的cpu，内存情况如下：
server ok, TPS: 77.2, error: 55%, 平均响应时间： 25s。只能说，服务端没死，但是基本已经不怎么可用了！
到最后，我压到 6000 的并发时，server 仍然没有挂掉！
所以，nio，是比较强悍的！
不要害怕今日的苦，你要相信明天，更苦！
