undertow web服务器初体验

1.Undertow介绍

Undertow is a web server designed to be used for both blocking and non-blocking tasks. Some of its main features are:

  • High Performance
  • Embeddable
  • Servlet 4.0
  • Web Sockets
  • Reverse Proxy

There and two main ways that Undertow can be used, either by directly embedding it in your code, or as part of the Wildfly Application Server. This guide mostly focuses on the embedded API’s, although a lot of the content is still relevant if you are using Wildfly, it is just that the relevant functionality will generally be exposed via XML configuration rather than programatic configuration.

The documentation is broken up into two parts, the first part focuses on Undertow code, while the second focuses on Servlet.

2.springboot整合

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-tomcat</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-undertow</artifactId>
        </dependency>
​```xml

3.springboot 在undertow下的运行效率

可见一个2.372s，一个2.751s，的确undertow快了一点点，再加上它的高并发，略胜tomcat。
