关于springmvc的hello world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！
