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 {}
}

如何在我的情况下正确配置JsonView
?可能是我忘记了什么?
答案 0 :(得分:0)
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'
