jhipster中下拉列表的过滤值

Question

我是Java和Angular初学者。 我将jdl文件设计如下。

在Lookus表的值的过滤器中，我无法显示仅显示国家或城市的语法

可以更好地描述此屏幕截图： https://pasteboard.co/IbpZhEb.png

application {
  config {
    applicationType monolith,
    baseName app
    packageName com.mycompany.myapp,
    authenticationType jwt,
    prodDatabaseType postgresql,
    devDatabaseType postgresql,
    cacheProvider ehcache,
    enableHibernateCache true,
    buildTool maven,
    searchEngine elasticsearch,
    testFrameworks [protractor],
    clientFramework angularX,
    useSass true,
    enableTranslation true,
    nativeLanguage en,
    languages [en, fa ,ar-ly]
  } 

entities LookupType, Lookups ,Person 
}

entity LookupType {
  lookupTypeIdentification Integer required,
  lookupTypeDiscription String required 
}
filter LookupType

entity Lookups {
  lookupsDiscription String required 
}
filter Lookups

entity Person {
  nationalCode Long required ,
  name String required ,
  family String required ,
  birithDate ZonedDateTime,
  gender Gender
}

enum Gender {
    MEN, WOMEN
}

relationship OneToMany {
LookupType {lTDiscription} to Lookups{lookupTypeDiscription(lookupTypeDiscription)}
}


relationship OneToMany {
Lookups {Country} to Person{Nationality(lookupsDiscription)}
Lookups {city} to Person{birthPlace(lookupsDiscription)}
Lookups {color} to Person{hairColor(lookupsDiscription)}
}
service all with serviceImpl except Lookups , LookupType ,Person
paginate Lookups with infinite-scroll
paginate LookupType with pagination
paginate Person with infinite-scroll

我有几个问题： 1.这可以通过jdl吗？当然，无需添加太多表！ 2.如果上述问题的答案是否定的，那么解决方案是什么？ 3）Angular什么路径从Spring接收数据？（代码）
