如何在使用jhipster创建实体后删除它？

时间：2015-01-29 23:02:51

标签： jhipster

我使用＆＃34; yo jhipster：entity＆＃34;创建了3个实体（作者，书籍，图书馆）。命令，但在一个实体（库）中我有一个ManyToMany关系（预订），但导致＆＃34; mappedBy引用一个未知的目标实体属性：com.tst.testdomain中的com.tst.testdomain.domain.Book.librarys。 docmain.Library.books＆＃34;那么什么是删除库实体的干净方式。一个命令会像＆＃34; yo jhipster：entitydelete＆＃34;有用吗？

我使用git scm。这不仅仅是需要删除的生成文件。 jHipster还会修改文件，以便保存文件但需要保留文件，而不是修改文件。

每次创建实体时，我都会单独提交，以便跟踪jHipster为每个实体所做的事情。

清除自上次提交以来的所有更改

git reset --hard
git clean -fd

如果我已经这样做但我还需要退出之前的提交，那么我就

git reset --hard HEAD~1

提交是git本地的，所以直到你推送这些提交才会共享它们。

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/test/java/com/radsphere/jeces/web/rest/YourEntityResourceTest.java
rm -rf src/main/webapp/i18n/en/YourEntity.json
rm -rf src/main/webapp/i18n/fr/YourEntity.json

从config / liquibase / master.xml中删除引用：

我执行拉取请求以添加此功能： https://github.com/jhipster/generator-jhipster/pull/4369

要使用它，它很简单：

yo jhipster:entity Foo --remove

它删除了liquibase脚本，但在您需要处理已创建但尚未删除的表/列族之后。

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

你是对的，删除命令会很有用。但是这个命令今天不存在。也许它会被添加。如果要删除实体，则必须手动执行。因此，删除实体的所有生成文件：domain，repository，rest，test，Angularjs controller＆amp;服务，HTML视图，菜单链接，HTML视图

答案 4 :(得分：6)

很简单，你只需删除目录.jhipster / entityName.json上的实体就可以了。

您可以运行＆＃34; yo：jhipster实体＆＃34;再次覆盖其他一切。

已编辑：为较新版本的jhipster 3.9.0添加了脚本

我的 delete-entity.sh jhipster Release 2.26.2脚本，基于@shacharsol的回答。

用法：./ delete-entity GROUP_ID ENTITY_NAME

GROUP_ID：com / subpackage /和/ so / on /（以'/'结尾）

ENTITY_NAME：firstLowercaseNameOfEntity

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，您需要创建一个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，您的文件可能更少（或者可能更多）。

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“使用DTO”，则需要删除为该实体生成的 DTO 文件，
  • JHipster使用 Mapstruct 来映射实体和 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
  • 如果您想要更新更新实体定义并在将来重新生成实体，您可以保留 ./。jhipster / $ {ENTITY_NAME} .json

我更新了SparX的bash脚本（delete-entity.sh），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）不会在较旧的bash版本（例如3.2）中运行。

更新后的bash脚本如下所示。只需将此脚本放在 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”，并且您要删除名为“city”的实体 ，下面给出了一个示例命令：

./ delete-entity.sh com / example / city 

#!/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}
