我的目标是配置 objectMapper
,使其仅序列化带有 @JsonProperty
注释的元素。
为了做到这一点,我遵循了 explanation其中说明了如何配置 objectmapper。
我包含了自定义对象映射器,如 here 所述.
但是,当类 NumbersOfNewEvents
被序列化时,它仍然包含 json 中的所有属性。
有人有提示吗? 提前致谢
jackson 1.8.0 Spring 3.0.5
CustomObjectMapper
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));
}
}

NumbersOfNewEvents
public class NumbersOfNewEvents implements StatusAttribute {
public Integer newAccepts;
public Integer openRequests;
public NumbersOfNewEvents() {
super();
}
}
最佳答案
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;
}
}
