这节主要介绍下如何调用其他的mapper

1.修改上节用到的FlightConverter，新增List的映射

@Mapper
interface FlightConverter {fun convertToDto(flight: Flight) : FlightDtofun convertToModel(flightDto: FlightDto) : Flightfun flightToDtos(cars: List<Flight>): List<FlightDto>fun dtoToFlights(cars: List<FlightDto>): List<Flight>
}

2.添加新的业务类

import java.time.LocalDatedata class Person(var firstName: String?,var lastName: String?,var phoneNumber: String?,var birthdate: LocalDate?,var flight: Flight?,var flights: List<Flight>) {// Necessary for MapStructconstructor() : this(null, null, null, null, null, listOf())
}import java.time.LocalDatedata class PersonDto(var firstName: String?,var lastName: String?,var phone: String?,var birthdate: LocalDate?,var flightDto: FlightDto?,var flights:List<FlightDto>) {// Necessary for MapStructconstructor() : this(null, null, null, null,null, listOf())
}

3.添加业务类的映射

//类中的方法，进行字段映射时会使用FlightConverter中定义的方法
@Mapper(uses = [FlightConverter::class])
interface PersonConverter {//配置对应字段@Mappings(value = [Mapping(source = "phoneNumber", target = "phone"),Mapping(source = "flight",target = "flightDto")])fun convertToDto(person: Person) : PersonDto//对convertToDto实现逆映射，如果如果有多个方法，可以通过name属性//指定，如@InheritInverseConfiguration(name = "convertToDto")@InheritInverseConfigurationfun convertToModel(personDto: PersonDto) : Person}

4.调用一下吧

 val converter = Mappers.getMapper(PersonConverter::class.java) // or PersonConverterImpl()val flight = Flight(flightId = 1,flightName = "CX 101")val person = Person("Samuel","Jackson","0123 334466",LocalDate.of(1948, 12, 21),flight, listOf(flight))println(person)val personDto = converter.convertToDto(person)println(personDto)val personModel = converter.convertToModel(personDto)println(personModel)

输出

Person(firstName=Samuel, lastName=Jackson, phoneNumber=0123 334466, birthdate=1948-12-21, flight=Flight(flightId=1, flightName=CX 101), flights=[Flight(flightId=1, flightName=CX 101)])
PersonDto(firstName=Samuel, lastName=Jackson, phone=0123 334466, birthdate=1948-12-21, flightDto=FlightDto(flightId=1, flightName=CX 101), flights=[FlightDto(flightId=1, flightName=CX 101)])
Person(firstName=Samuel, lastName=Jackson, phoneNumber=0123 334466, birthdate=1948-12-21, flight=Flight(flightId=1, flightName=CX 101), flights=[Flight(flightId=1, flightName=CX 101)])

发现已经生效了
