JHipster 7.1.0: Failed to use jdl-import, throws Error looking for otherEntity User at
我正在使用 java Openjdk 11.0.11、JHipster 7.1.0 和节点 v14.17.3
我正在创建一个简单的微服务（一个后端和一个网关）但是 JHipster 无法使用 jdl 命令（jdl-import）创建，它抛出

它确实创建了文件夹 blogBackend、blogGateWat 和 docker-compose ....但是文件夹 blogBackend 是空的。
如果我移动到 blogGateWay 并且 运行：mvn clean install
我也遇到异常；

重现步骤：
1 - 创建文件夹博客
2 - 移至文件夹博客
3 - 运行：jhipster jdl blog.jdl
4 - 移动到 blogGateWay
5 - 运行：mvn 全新安装

发生错误是因为您使用的是 JWT 身份验证类型，而不是 OAuth2。
对于 OAuth2，微服务中有一种机制可以从令牌中提取用户数据并将其保存到服务的数据库中。
不幸的是，我找不到任何关于此的文档所以我阅读了代码
https://github.com/jhipster/generator-jhipster/blob/main/utils/entity.js 其中判断是否激活此用户快照的测试是：
entityWithConfig.saveUserSnapshot =
entityWithConfig.applicationType === MICROSERVICE &&
entityWithConfig.authenticationType === OAUTH2 &&
hasBuiltInUserField &&
entityWithConfig.dto === NO_MAPPER;
可以看到还有一个条件是不使用DTO
虽然这种机制有一些限制，因为用户的数据只有在调用服务 API 时才会更新，您可以想象在网关中更新用户并且后台作业是 运行 的情况在服务中将使用过时的用户版本。
对于 JWT，这还没有实现，因为令牌没有包含足够的用户数据，它只包含登录名和角色。
那么对于 JWT，您能否在博客中仅存储用户的 ID（或登录名）而不定义与用户实体的关系，因为它仅存在于网关数据库中。
几乎相同的错误我花了一个小时才找到解决方案。在我的例子中，我写错了关系实体名称，所以写正确的关系实体名称就成功了。我在写：
ChatToSearch
但我的实体名称是：
ChatsToSearch
所以，我已经更正了它并且成功了！

发生错误是因为您使用的是 JWT 身份验证类型，而不是 OAuth2。
对于 OAuth2，微服务中有一种机制可以从令牌中提取用户数据并将其保存到服务的数据库中。
不幸的是，我找不到任何关于此的文档所以我阅读了代码 https://github.com/jhipster/generator-jhipster/blob/main/utils/entity.js 其中判断是否激活此用户快照的测试是：
entityWithConfig.saveUserSnapshot =
entityWithConfig.applicationType === MICROSERVICE &&
entityWithConfig.authenticationType === OAUTH2 &&
hasBuiltInUserField &&
entityWithConfig.dto === NO_MAPPER;
可以看到还有一个条件是不使用DTO
虽然这种机制有一些限制，因为用户的数据只有在调用服务 API 时才会更新，您可以想象在网关中更新用户并且后台作业是 运行 的情况在服务中将使用过时的用户版本。
对于 JWT，这还没有实现，因为令牌没有包含足够的用户数据，它只包含登录名和角色。
那么对于 JWT，您能否在博客中仅存储用户的 ID（或登录名）而不定义与用户实体的关系，因为它仅存在于网关数据库中。
几乎相同的错误我花了一个小时才找到解决方案。在我的例子中，我写错了关系实体名称，所以写正确的关系实体名称就成功了。我在写：
ChatToSearch
但我的实体名称是：
ChatsToSearch
所以，我已经更正了它并且成功了！
