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.     <filter>
  2.         <filter-name>SpringEncodingFilter</filter-name>
  3.         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  4.         <init-param>

  11.         </init-param>
  12.     </filter>
  13.     <filter-mapping>
  14.         <filter-name>SpringEncodingFilter</filter-name>
  15.         <url-pattern>/*</url-pattern>
  16.     </filter-mapping>
  17.     <!-- 防止Spring内存溢出监听器 -->
  18.     <listener>
  19.         <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
  20.     </listener>

  22.     <!--<listener>
  23.         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  24.     </listener>-->
  25.     <!-- springMVC核心配置 -->
  26.     <servlet>
  27.         <servlet-name>dispatcherServlet</servlet-name>
  28.         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  29.         <init-param>
  30.             <param-name>contextConfigLocation</param-name>
  31.             <param-value>classpath:applicationContext.xml</param-value>
  32.         </init-param>
  33.         <load-on-startup>1</load-on-startup>
  34.     </servlet>
  35.     <!-- 拦截设置 -->
  36.     <servlet-mapping>
  37.         <servlet-name>dispatcherServlet</servlet-name>
  38.         <url-pattern>/*</url-pattern>
  39.     </servlet-mapping>
  40.     <welcome-file-list>
  41.         <welcome-file>index.html</welcome-file>
  42.         <welcome-file>index.jsp</welcome-file>
  43.     </welcome-file-list>

1.3. 添加log4j.properties日志配置文件

  1. log4j.rootLogger=DEBUG,console,im,logFile
  2. log4j.additivity.org.apache=true
  3. # 控制台(console)
  4. log4j.appender.console=org.apache.log4j.ConsoleAppender
  5. log4j.appender.console.Threshold=DEBUG
  6. log4j.appender.console.ImmediateFlush=true
  7. log4j.appender.console.Target=System.out
  8. log4j.appender.console.layout=org.apache.log4j.PatternLayout
  9. log4j.appender.console.layout.ConversionPattern=%d(%r) [%t] %-5p %l: %m %x %n
  10. # 日志文件(logFile)
  11. log4j.appender.logFile=org.apache.log4j.FileAppender
  12. log4j.appender.logFile.Threshold=DEBUG
  13. log4j.appender.logFile.ImmediateFlush=true
  14. log4j.appender.logFile.Append=true
  15. log4j.appender.logFile.File=D:/logs/log.log4j
  16. log4j.appender.logFile.layout=org.apache.log4j.PatternLayout
  17. log4j.appender.logFile.layout.ConversionPattern=%d(%r) [%t] %-5p %l: %m %x %n
  18. # 回滚文件(rollingFile)
  19. log4j.appender.rollingFile=org.apache.log4j.RollingFileAppender
  20. log4j.appender.rollingFile.Threshold=DEBUG
  21. log4j.appender.rollingFile.ImmediateFlush=true
  22. log4j.appender.rollingFile.Append=true
  23. log4j.appender.rollingFile.File=D:/logs/log.log4j
  24. log4j.appender.rollingFile.MaxFileSize=200KB
  25. log4j.appender.rollingFile.MaxBackupIndex=
  26. log4j.appender.rollingFile.layout=org.apache.log4j.PatternLayout
  27. 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

  1. @RestController
  2. @RequestMapping("/hello")
  3. public class HelloController {
  4.  
  5.     @RequestMapping(value = "/world", method = {RequestMethod.GET, RequestMethod.POST}, produces = "application/json")
  6.     @ResponseBody
  7.     public Object world(@ModelAttribute UserInfo info) {
  8.         return "hello world!";
  9.     }
  10. }

　　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：

　　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！
