spring-boot-starter-undertow

组件简介

将 Undertow 容器嵌入到 Spring Boot

使用说明

1、Spring Boot 项目添加 Maven 依赖

<!-- For Embed Undertow -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-undertow</artifactId>
</dependency>

2、集成 Prometheus 监控

项目中引入 micrometer-prometheus 依赖，可实现 Undertow 容器的指标采集

<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
</dependency>
<dependency>
    <groupId>com.github.hiwepy</groupId>
    <artifactId>undertow-metrics-prometheus</artifactId>
</dependency>

可采集到如下指标：

undertow_request_time_max_seconds{application="app-test",} NaN
