Spring + Kotlin中的JsonView

服务器使用JsonView返回空json:

[ { }, { } ]

我只使用Jackson2ObjectMapperBuilder bean来配置jackson

@Bean
open fun objectMapperBuilder() = Jackson2ObjectMapperBuilder()
    .modulesToInstall(KotlinModule())
    .propertyNamingStrategy(PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES)
    .featuresToEnable(SerializationFeature.WRITE_EMPTY_JSON_ARRAYS)

控制器:

@RestController
@RequestMapping("/api/drivers")
class DriversController @Autowired constructor(val driverService: DriverService) {

    @JsonView(Views.Public::class)
    @RequestMapping("/nearest")
    fun nearest(): List<Driver> {
        val drivers = driverService.findNearest(49.437551, 32.025263)

        return drivers
    }

驱动程序表实体:

@Entity
@Table(name = "ct_drivers")
data class Driver(

    @Id
    @Column(name = "id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    var id: Int = 0,

    @JsonView(Views.Public::class)
    @Column(name = "first_name")
    var firstName: String = "",

    @JsonView(Views.Public::class)
    @Column(name = "last_name")
    var lastName: String = "",

    @Column(name = "phone")
    var phone: String = ""

)

观看对象:

object Views {
    interface Public {}
}

依赖关系列表:

compile 'org.springframework.boot:spring-boot-devtools'
compile 'org.springframework.boot:spring-boot-starter-data-jpa'

如何在我的情况下正确配置JsonView?可能是我忘记了什么?

我遇到了同样的问题,直到我添加了以下依赖项:

compile 'com.fasterxml.jackson.module:jackson-module-kotlin'
