从零开始搭建flink流式计算项目-1项目创建

项目搭建

我这里使用的是 jdk17,
flink版本 1.18.1

1. 新建maven项目 pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
