JsonView在Spring + Kotlin中
服务器用JsonView返回空的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 { 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 = "" )
视图对象：
object Views { interface Public {} }
依赖项列表：
compile 'org.springframework.boot:spring-boot-starter-web' compile 'org.springframework.boot:spring-boot-devtools' compile 'org.springframework.boot:spring-boot-starter-data-jpa' compile 'org.springframework.boot:spring-boot-starter-thymeleaf' compile 'org.springframework.security.oauth:spring-security-oauth2' compile 'org.springframework:spring-messaging' compile 'org.springframework:springloaded:1.2.5.RELEASE' compile 'org.springframework:spring-tx' compile 'org.springframework:spring-orm:4.2.5.RELEASE' compile 'org.hibernate:hibernate-core:5.1.0.Final' compile 'org.hibernate:hibernate-entitymanager:5.1.0.Final' compile 'org.hibernate:hibernate-spatial:5.1.0.Final' compile 'com.corundumstudio.socketio:netty-socketio:1.7.8' compile 'org.postgresql:postgresql:9.3-1101-jdbc41' compile 'com.github.salomonbrys.kotson:kotson:2.1.0' compile 'com.fasterxml.jackson.module:jackson-module-kotlin:2.7.3' compile 'org.apache.httpcomponents:httpcore:4.3.3' compile 'org.apache.httpcomponents:httpclient:4.3.3' compile "org.jetbrains.kotlin:kotlin-stdlib:${kotlinVersion}"
如何在我的情况下正确配置JsonView ？ 可能是我忘了什么？
我遇到了同样的问题，直到我添加以下依赖项：
compile 'com.fasterxml.jackson.module:jackson-module-kotlin'
