java - 无法使用网关 UI 将数据保存到 JHipster 微服务中

Question

我使用一个微服务和一个网关设置了我的微服务应用程序。我使用 $jhipster import-jdl books.jh 命令和网关中的实体 UI 生成了微服务实体。网关中的 JDL 文件与“skipServer”等选项略有不同。我使用下面的文件为网关中的实体以及微服务中生成的实体生成 UI。我正在查看其他人提出的所有文档和问题，但我找不到正确的文档来使用微服务和 UI 为网关中的这些实体生成实体(需要在 JDL 文件中指定微服务的路径)。如果我的语法不正确，请纠正我。一切顺利，当打开我的实体页面并尝试保存对象时，它没有保存它。我在控制台上收到以下错误。

JDL 文档对此并不清楚。您可以为此使用一个 JDL 文件并在其中指定一个微服务名称。删除skipServer选项，因为JHipster会自动为你做这件事。关注 this discussion on Github .

更新的 JDl 文件:

entity Address
{
    streetName  String required,
    apartmentOrHouseNumber  String,
    city    String  required,
    zipcode Long    required,
    state   String,
    country String
}

entity BookCoverType
{
    coverType   String  required
}


entity Author
{
    firstName   String  required,
    lastName    String  required,
    middleName  String,
}

entity Book 
{
    bookName String required,
    bookTitle String    required,
    numberOfPages Integer   required,
}




relationship OneToOne 
{
    //Book{bookCoverType(coverType)} to BookCoverType
    Author{address(streetName)} to Address
}

relationship OneToMany 
{
    BookCoverType{book(bookTitle)} to Book
    Book{author(firstName)} to Author
    Author{book(bookTitle)} to Book

}
