如何使用jhipster创建实体后删除它？

问题描述 投票：0回答：9

我使用“yo jhipster:entity”命令创建了 3 个实体（作者、书籍、图书馆），但在一个实体（图书馆）中，我有一个多对多关系（与书籍），但这导致“mappedBy 引用未知的目标实体属性：com” com.tst.testdomain.docmain.Library.books 中的.tst.testdomain.domain.Book.librarys”那么删除 Library 实体的干净方法是什么。像“yo jhipster:entitydelete”这样的命令有用吗？

我为此使用 git scm 。需要删除的不仅仅是生成的文件。 jHipster 还会修改文件，因此您需要保留文件但取消更改。

每次创建实体时，我都会进行单独的提交，这样我就可以跟踪 jHipster 对每个实体所做的操作。

清除自上次提交以来的所有更改

git reset --hard
git clean -fd

如果我已经这样做了，但我还需要取消之前的提交，那么我会这样做

git reset --hard HEAD~1

提交是 git 本地的，因此直到您推送这些提交后它们才会被共享。

我提出了一个拉取请求来添加此功能： https://github.com/jhipster/generator-jhipster/pull/4369

使用方法非常简单：

yo jhipster:entity Foo --remove

它删除了 liquibase 脚本，但在您需要处理已创建且尚未删除的表/列系列之后。

如果您对此感兴趣，请投票或评论该问题： https://github.com/jhipster/generator-jhipster/issues/4372

您应该删除以下内容：

rm -rf   src/main/resources/config/liquibase/changelog/XXX_added_entity_YourEntity.xml
rm -rf src/main/java/com/radsphere/jeces/domain/YourEntity.java
rm -rf src/main/java/com/radsphere/jeces/repository/YourEntityRepository.java
rm -rf src/main/java/com/radsphere/jeces/web/rest/YourEntityResource.java 
rm -rf src/main/webapp/scripts/app/entities/YourEntity/YourEntitys.html
rm -rf src/main/webapp/scripts/app/entities/YourEntity/YourEntity-detail.html
rm -rf src/main/webapp/scripts/app/entities/YourEntity/YourEntity.js
rm -rf src/main/webapp/scripts/app/entities/YourEntity/YourEntity.controller.js
rm -rf src/main/webapp/scripts/app/entities/YourEntity/YourEntity-detail.controller.js
rm -rf  src/main/webapp/scripts/components/entities/YourEntity/YourEntity.service.js

rm -rf src/main/webapp/i18n/en/YourEntity.json
rm -rf src/main/webapp/i18n/fr/YourEntity.json

并从 config/liquibase/master.xml 中删除引用：

你是对的，删除命令会很有用。但今天这个命令已经不存在了。也许会添加。如果要删除实体，则必须手动执行。因此，删除为您的实体生成的所有文件：域、存储库、休息、测试、Angularjs 控制器和服务、HTML 视图、菜单中的链接、HTML 视图

很简单，您只需删除目录 .jhipster/entityName.json 上的实体即可。

您可以再次运行“yo:jhipster实体”并覆盖其他所有内容。

编辑：为新版本的 jhipster 3.9.0 添加了脚本

我的 jhipster delete-entity.sh 脚本Release 2.26.2，基于@shacharsol 的答案。

用法：./delete-entity GROUP_ID ENTITY_NAME

GROUP_ID：com/subpackage/and/so/on/（以“/”结尾）

ENTITY_NAME：实体的第一个小写名称

示例：./delete-entity uz/javlon/ transInfo

#!/usr/bin/env bash

echo "################";

if [ -z "$1" ];
then
    printf "Required argument GROUP_ID is not set. \nUsage: ./delete-entity.sh GROUP_ID ENTITY_NAME.\n";
    exit 1;
else
    GROUP_ID=$1;
    echo "GROUP_ID is set to '$1'.";
fi

if [ -z "$2" ];
then
    printf "Required argument ENTITY_NAME is not set. \nUsage: ./delete-entity.sh GROUP_ID ENTITY_NAME .\n";
    exit 1;
else
    ENTITY_NAME=$2;
    echo "ENTITY_NAME is set to '$2'.";

在 jHipster 7.0.1 中，您应该删除以下文件：

jhipster/[EntityName].json
src/main/java/[base package]/domain/[EntityName].java
src/main/java/[base package]/repository/[EntityName]Repository.java
src/main/java/[base package]/repository/search/[EntityName]SearchRepository.java
src/main/java/[base package]/service/[EntityName]Service.java
src/main/java/[base package]/service/dto/[EntityName]DTO.java
src/main/java/[base package]/service/impl/[EntityName]ServiceImpl.java
src/main/java/[base package]/service/mapper/[EntityName]Mapper.java
src/main/java/[base package]/web/rest/[EntityName]Resource.java
src/main/resources/config/liquibase/changelog/*_added_entity_[EntityName].xml
src/main/resources/config/liquibase/changelog/*_added_entity_constraints_[EntityName].xml
src/main/resources/config/liquibase/fake-data/[entity_name].csv
src/test/java/[base package]/domain/[EntityName]Test.java
src/test/java/[base package]/repository/search/[EntityName]SearchRepositoryMockConfiguration.java
src/test/java/[base package]/service/dto/[EntityName]DTOTest.java
src/test/java/[base package]/service/mapper/[EntityName]MapperTest.java
src/test/java/[base package]/web/rest/[EntityName]ResourceIT.java

删除整个目录：

src/main/webapp/app/entities/[entity-name]

从以下文件中删除引用：

.yo-rc.json
src/main/java/[base package]/config/CacheConfiguration.java
src/main/resources/config/liquibase/master.xml
src/main/webapp/app/entities/entity-routing.module.ts
src/main/webapp/app/layouts/navbar/navbar.component.html
src/main/webapp/i18n/en/global.json
src/main/webapp/i18n/pt-br/global.json

删除数据库并让应用程序在启动时再次生成它。 如果您无法删除数据库，则需要创建更改日志来删除过时的表，而不是删除 liquibase 文件。

显然，根据您生成项目的方式，您可能拥有更少的文件（或者可能更多的文件）。

我对 SparX 和 Meme 的答案做了一些补充。

  • 如果您在生成实体时选择了“使用 DTO”，则需要删除为实体生成的 DTO 文件，
  • JHipster 使用 Mapstruct 来映射 Entity 和 DTO。如果你使用DTO，那么你需要删除JHipster为你生成的mapper类
  • 您需要从“webapp/index.html”中删除已删除实体的javascript文件引用
  • 您需要从“webapp/i18n/*/global.json”中删除已删除实体的 i18n 定义
  • 您需要从 “webapp/scripts/components/navbar.html”
    • 中删除菜单链接
  • 如果以后想更新实体定义并重新生成实体，可以保留 ./.jhipster/${ENTITY_NAME}.json

我更新了SparX的bash脚本（delete-entity.sh）以询问是否删除实体定义文件。 此外， "${ENTITY_NAME^}" 语法（用于将实体名称的第一个字母转换为大写）不在较旧的 bash 版本（例如 3.2）中运行。

更新后的 bash 脚本如下。只需将此脚本放入您的 pom.xml 所在的文件夹中即可。

示例用例： 如果您的项目的 groupId “com.example” 并且您想删除名为 “city” 的实体，下面给出了示例命令：

./delete-entity.sh com/example/城市 

#!/usr/bin/env bash
echo;
if [ -z "$1" ];
then
    printf "Required argument GROUP_ID is not set. \nUsage: ./delete-entity.sh GROUP_ID ENTITY_NAME.\n";
    exit 1;
else
    GROUP_ID=$1;
    echo "GROUP_ID is set to '$1'.";
fi

if [ -z "$2" ];
then
    printf "Required argument ENTITY_NAME is not set. \nUsage: ./delete-entity.sh GROUP_ID ENTITY_NAME .\n";
    exit 1;
else
    ENTITY_NAME=$2;
    JAVA_ENTITY_NAME=`echo ${ENTITY_NAME:0:1} | tr  '[a-z]' '[A-Z]'`${ENTITY_NAME:1} 
    echo "ENTITY_NAME is set to '$2'." 
    echo "Java entity name inferred as: '${JAVA_ENTITY_NAME}'.";
fi

JAVA_ENTITY_NAME=`echo ${ENTITY_NAME:0:1} | tr  '[a-z]' '[A-Z]'`${ENTITY_NAME:1}

9年零11个月前提问，2年零9个月前修改。然而 jhipster 并没有提供任何删除功能。有这么难吗
