SpringBoot2.0之Servlet容器变成Undertow

前言

默认情况下，Spring Boot 使用 Tomcat 来作为内嵌的 Servlet 容器
可以将 Web 服务器切换到 Undertow 来提高应用性能。Undertow 是一个采用 Java 开发的灵活的高性能 Web 服务器，提供包括阻塞和基于 NIO 的非堵塞机制。Undertow 是红帽公司的开源产品，是 Wildfly 默认的 Web 服务器。

一、测试吞吐量工具
apache-jmeter-5.3.zip

二、文件目录

三、文件内容
1.AppMyBatis04.java

package com.zhongguancun;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@MapperScan("com.zhongguancun.mapper")
@SpringBootApplication
public class AppMyBatis04 {
    
    
	
	public static void main(String[] args) {
    
    
		SpringApplication.run(AppMyBatis04.class, args);
	}
}

2.IndexController.java

package com.zhongguancun.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class IndexController {
    
    

	@RequestMapping("/index")
	public String indexDev() {
    
    
	//打开次注释可以后台看到访问痕迹
//		System.out.println("index + 1");
		return "index";
	}
	
	
}

3.pom.xml

四、效果测试
运行项目

测试工具配置：

1.Undertow吞吐量

吞吐量8000多

2.Servlet吞吐量
停掉项目 修改pom.xml文件
注释掉undertow

</project>

运行项目
然后运行测试

Servlet吞吐量5000多

总结

服务器名称	第一次运行	第二次运行	第三次运行	平均值
Tomcat	4773	5194	5334.7	5100
Undertow	6666	6373	6451	6496
