spring 多模块项目启动

Question

我正在使用 Spring 框架来生成 Web 应用程序。 我更喜欢使用多模块项目来使我的应用程序可读。 这是我的项目的层次结构

我的父项目 pom.xml ：

<?xml version="1.0" encoding="UTF-8"?>

当我从 intellij 启动我的应用程序时，它启动良好，但是当我尝试使用 (mvn spring-boot:start) 从命令行启动它时出现问题，出现以下错误

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.5.6:start (default-cli) on project IReviewParent: Could not contact Spring Boot application: Failed to retrieve RMIServer stub: javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is: 
[ERROR]     java.net.SocketException: Connection reset]

我也想知道。如果我想托管我的应用程序，我需要一个 jar 将其放入主机中，我从哪里获得它？如何从 cmd 行启动它？ 请帮忙！！！！

Answer 1

从命令行运行启动它：

mvn spring-boot:run

你可以在 /target 目录中找到的 jar
