在Spring中配置ObjectMapper

我的目标是配置objectMapper,使其仅序列化带有注释的元素@JsonProperty

为了做到这一点,我按照下面的说明进行了说明,该说明说明了如何配置对象映射器。

我包括自定义描述objectmapper 这里。

但是,当类NumbersOfNewEvents被序列化时,它仍包含json中的所有属性。

有人暗示吗?提前致谢

Jackson 1.8.0 spring 3.0.5

public class CompanyObjectMapper extends ObjectMapper {

public CompanyObjectMapper() {

super();

setVisibilityChecker(getSerializationConfig()

.getDefaultVisibilityChecker()

.withCreatorVisibility(JsonAutoDetect.Visibility.NONE)

.withFieldVisibility(JsonAutoDetect.Visibility.NONE)

.withGetterVisibility(JsonAutoDetect.Visibility.NONE)

.withIsGetterVisibility(JsonAutoDetect.Visibility.NONE)

.withSetterVisibility(JsonAutoDetect.Visibility.DEFAULT));

}

}

public class NumbersOfNewEvents implements StatusAttribute {

public Integer newAccepts;

public Integer openRequests;

public NumbersOfNewEvents() {

super();

}

}

回答:

使用Spring Boot(1.2.4)和Jackson(2.4.6),以下基于注释的配置对我有用。

@Configuration

public class JacksonConfiguration {

@Bean

public ObjectMapper objectMapper() {

ObjectMapper mapper = new ObjectMapper();

mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

mapper.configure(MapperFeature.DEFAULT_VIEW_INCLUSION, true);

return mapper;

}

}
