JHipster jdl导入实体生成器未能在实体之间创建关系

编程问答 2022-06-06

问题描述

我正在使用JHipster JDL生成实体。

INFO！使用当前项目的node_modules中本地安装的JHipster版本 6.10.1

用于生成实体的JDL

@H_404_6@entity Products{ name String required brand String required quantity String required messurement String description String } entity ProductTypes{ productType String required description String } relationship ManyToOne{ Products{productType} to ProductTypes } // Set pagination options paginate all with pagination // Use Data Transfert Objects (DTO) dto * with mapstruct // Set service options to all except few service all with serviceImpl // Set an angular suffix // angularsuffix * with mySuffix

使用以下命令运行JDL并成功运行，没有任何错误

@H_404_6@$jhipster import-jdl jdl/jhipster-jdl.jdl Output Summary: DONE Compiled successfully in 23047ms 4:15:42 PM 489 modules INFO! Congratulations,JHipster execution is complete!

现在，当尝试启动应用程序时，出现错误

能否请您帮助我理解为什么引发此错误。我是否以正确的方式使用JHipster实体生成器？

感谢您的帮助。

解决方法

将JHipster从6.10.1升级到6.10.4后问题得到解决

在下面的命令中用于升级，就像魅力

jhipster upgrade

我遵循的两件事：

  1. 我不得不使用删除并重新安装节点模块
rm -rf node_modules 
npm install
  1. 在升级时，它询问了以下一个问题。我只单击了Enter，我猜它采用了默认选项
git rev-parse -q --abbrev-ref HEAD
master
? Unify blueprints configurations?


git rev-parse -q --abbrev-ref HEAD
master
? Unify blueprints configurations? Yes
     info Skipping config upgrade,config generated with jhipster version: 6.10.1
git rev-parse -q --verify jhipster_upgrade
git checkout --orphan jhipster_upgrade
Switched to a new branch 'jhipster_upgrade'
✔ Created branch jhipster_upgrade
