　　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

           1.8

1.2. 添加一个 web.xml, 只加一个dispatcherServlet 和一个字符集转换过滤器


             
      
       SpringEncodingFilter
              
      
       org.springframework.web.filter.CharacterEncodingFilter
              
                  
       
        encoding
                   
       
        UTF-8
               
              
                  
       
        forceEncoding
                   
       
        true
               
          
         
             
      
       SpringEncodingFilter
              
      
       /*
          
         
         
             
      
       org.springframework.web.util.IntrospectorCleanupListener
          
         
         
         
         
             
      
       dispatcherServlet
              
      
       org.springframework.web.servlet.DispatcherServlet
              
                  
       
        contextConfigLocation
                   
       
        classpath:applicationContext.xml
               
              
      
       1
          
         
         
             
      
       dispatcherServlet
              
      
       /*
          
         
             
      
       index.html
              
      
       index.jsp

1.3. 添加log4j.properties日志配置文件

log4j.rootLogger=DEBUG,console,im,logFilelog4j.additivity.org.apache=true# 控制台(console)log4j.appender.console=org.apache.log4j.ConsoleAppenderlog4j.appender.console.Threshold=DEBUGlog4j.appender.console.ImmediateFlush=truelog4j.appender.console.Target=System.outlog4j.appender.console.layout=org.apache.log4j.PatternLayoutlog4j.appender.console.layout.ConversionPattern=%d(%r) [%t] %-5p %l: %m %x %n# 日志文件(logFile)log4j.appender.logFile=org.apache.log4j.FileAppenderlog4j.appender.logFile.Threshold=DEBUGlog4j.appender.logFile.ImmediateFlush=truelog4j.appender.logFile.Append=truelog4j.appender.logFile.File=D:/logs/log.log4jlog4j.appender.logFile.layout=org.apache.log4j.PatternLayoutlog4j.appender.logFile.layout.ConversionPattern=%d(%r) [%t] %-5p %l: %m %x %n# 回滚文件(rollingFile)log4j.appender.rollingFile=org.apache.log4j.RollingFileAppenderlog4j.appender.rollingFile.Threshold=DEBUGlog4j.appender.rollingFile.ImmediateFlush=truelog4j.appender.rollingFile.Append=truelog4j.appender.rollingFile.File=D:/logs/log.log4jlog4j.appender.rollingFile.MaxFileSize=200KBlog4j.appender.rollingFile.MaxBackupIndex=50log4j.appender.rollingFile.layout=org.apache.log4j.PatternLayoutlog4j.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：

十二月 12, 2018 11:54:25 上午 org.apache.tomcat.util.net.AprEndpoint$Poller run警告: Unexpected poller errorjava.lang.NullPointerException    at org.apache.tomcat.util.net.AprEndpoint$AprSocketWrapper.access$400(AprEndpoint.java:2537)    at org.apache.tomcat.util.net.AprEndpoint$Poller.run(AprEndpoint.java:1887)    at java.lang.Thread.run(Thread.java:745)十二月 12, 2018 11:54:25 上午 org.apache.tomcat.util.net.AprEndpoint$Poller run警告: Unexpected poller errorjava.lang.NullPointerException    at org.apache.tomcat.util.net.AprEndpoint$AprSocketWrapper.access$400(AprEndpoint.java:2537)    at org.apache.tomcat.util.net.AprEndpoint$Poller.run(AprEndpoint.java:1887)    at java.lang.Thread.run(Thread.java:745)## A fatal error has been detected by the Java Runtime Environment:##  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0000000180008005, pid=13444, tid=0x0000000000002e34## JRE version: Java(TM) SE Runtime Environment (8.0_101-b13) (build 1.8.0_101-b13)# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.101-b13 mixed mode windows-amd64 compressed oops)# Problematic frame:# C  [tcnative-1.dll+0x8005]## Failed to write core dump.

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！
