更新 jhipster 中的实体时，正确的解决方法是什么？

Question

我有一个 modelio UML 类模型。我一直在更新它，之后我运行 jhipster-uml .xmi 来重新生成实体。我总是以错误消息告终。我试图从 -jhipster 文件中删除 entity.json 文件，但它没有帮助。那么你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，但没有运气。

编辑：

我创建了一个新的 jhipster 应用程序并从 modelio UML 类模型创建了实体。一切正常。然后我只是在我的模型中添加了一个属性并从 xmi 文件重新生成实体，并且所有的 os 都再次损坏了。

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 -paginate 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changelog 5) 运行应用程序 6) 查看错误信息：

      classpath:config/liquibase/changelog/20150828220237_added_entity_Employee.xml::20150828220237::jhipster is now: 7:dd10f74a01a95b4e48c592e796a1d352

Answer 1

当我想重新生成所有表格时，我会这样做

1. 在 MODELIO 中更新模型
2. 重新导出 xmi
3. rm -rf ./.jhipster/
4. 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，和
   • 评论 “JHipster 将在此处添加 liquibase 更改日志”
5. 有时我必须从表DATABASECHANGELOG 中删除行（除了第一行有ID ='00000000000001'）
6. 重新运行jhipster-uml

Answer 2

问题是 jhipster-uml 不支持发展模式。换句话说，一旦 jhipster-uml 生成了您的应用程序资产和 liquibase 变更日志，它就会忘记它所做的事情，并且当它下次运行时，它会从头开始生成所有内容 - 这对于大多数工件来说都很好，但 不 strong> 用于更新日志。

有两种方法可以解决这个问题：

• 在重新运行 jhipster 之前删除更改日志

  • 在另一个答案中有详细说明，此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

  一起使用
  1. 修改您的 UML 模型
  2. 导出 xmi
  3. 运行jhipster-uml
  4. 恢复对变更日志的所有更改，包括 master.xml（使用 VCS 或文件历史记录）
  5. 编译你的Java代码：compileJava
  6. 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改日志，即包含更改并将记录添加到 master.xml。
  7. 使用bootRun 启动您的应用程序：liquibase 任务将执行所有未完成的更改日志

注意：删除和重命名实体时要小心：您必须从前端资产、java 类、更改日志、数据库表、.jhipster 实体中删除一些孤立文件.

Answer 3

以防万一有人遇到这种情况，并且正在使用 Gradle。这就是我所做的：

第一。检查 master.xml 文件和其中包含的文件以检查一切是否符合预期。

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。
