在 jhipster 中更新实体时正确的解决方法是什么？
What is correct workaround when updating entities in jhipster?
我有一个 modelio UML class 模型。我一直在更新它，之后我 运行 jhipster-uml .xmi 重新生成实体。我总是以错误消息告终。我试图从 -jhipster 文件中删除 entity.json 文件，但没有帮助。那么您能告诉我在开发过程中更新实体的正确解决方法是什么吗？我也尝试 运行 maven:diff 任务，但没有成功。
编辑：
我创建了一个新的 jhipster 应用程序并从 modelio UML class 模型创建了实体。一切正常。然后，我向我的模型添加了一个属性，并从 xmi 文件中重新生成了实体，所有内容 os 再次损坏。
我的工作流程是：
1) 将 uml 模型保存为 xmi 文件
2) 运行 jhipster-uml ac2.xmi -分页
3）在intellijIdea中编译我的应用程序
4) 运行 maven 任务：mvn compile liquibase:diff 创建一个新的变更日志
5) 运行 申请
6) 查看错误信息：

当我想重新生成所有 table 时，我会这样做
- 更新MODELIO中的模型
- 重新导出 xmi
rm -rf ./.jhipster/- 打开文件
src/main/resources/config/liquibase/master.xml 并删除所有 <include> 元素，除了
config/liquibase/changelog/00000000000000_initial_schema.xml，以及- 评论"JHipster will add liquibase changelogs here"
- 有时我必须从 table
DATABASECHANGELOG 中删除行（除了第一行 ID ='00000000000001'）
- 重新运行
jhipster-uml
问题是 jhipster-uml 不支持发展模式。换句话说，一旦 jhipster-uml 生成了你的应用程序资产和 liquibase 变更日志，它就会忘记它做了什么，当它下次运行时，它会从头开始生成所有东西——这对大多数工件来说都很好，但是 NOT 更新日志。
有两种方法可以解决这个问题：
在重新运行 jhipster
之前删除变更日志
- 在另一个答案中有详细说明，另外在重新运行您的应用程序之前删除所有现有的数据库表。
将 jhipster-uml 与 liquibase diff
结合使用
- 修改您的 UML 模型
- 导出 xmi
- 运行
jhipster-uml
- 还原所有更改到更改日志，包括 master.xml（使用 VCS 或文件历史记录）
- 编译您的 Java 代码：
compileJava
- 运行 Liquibase diff
liquibaseDiffChangelog：这会将您的实体与数据库的当前状态进行比较，并生成实际的更新日志，即包含更改并向 master.xml 添加记录。
- 使用
bootRun 启动您的应用程序：liquibase 任务将执行任何未完成的变更日志
注意：删除和重命名实体时要小心：您必须从前端资产中删除一些孤立文件，java 类、变更日志、数据库表、.jhipster 实体。
以防万一有人遇到这种情况，正在使用Gradle。这就是我所做的:
1st. Check master.xml file and files included there to check everything is as expected.
然后 clearChecksums .
根据 liquidbase 文档
它Removes current checksums from database. On next run checksums will be recomputed.
所以
打开liquidbase.gradle
并添加了以下条目：
task liquibaseClearChecksums(dependsOn: compileJava, type: JavaExec) {
group = "liquibase"
classpath sourceSets.main.runtimeClasspath
classpath configurations.liquibase
main = "liquibase.integration.commandline.Main"
args "--changeLogFile=src/main/resources/config/liquibase/changelog/" + buildTimestamp() +"_changelog.xml"
args "--referenceUrl=hibernate:spring:com.asimplemodule.deptmanager.domain?dialect=com.asimplemodule.deptmanager.domain.util.FixedPostgreSQL82Dialect&hibernate.ejb.naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringNamingStrategy"
args "--username=mycoolapp"
args "--password=mycoolapp"
args "--url=jdbc:postgresql://localhost:5432/mycoolApp"
args "--driver=org.postgresql.Driver"
args "clearChecksums"
}
然后 运行 gradle liquibaseClearChecksums
这解决了我的问题。
