如何全局设置Jackson忽略Spring中的未知属性？

对于杰克逊1.9x或更低版本，你可以使用对象映射器提供程序忽略未知属性

@Provider@Componentpublic class JerseyObjectMapperProvider implements ContextResolver<ObjectMapper> {    @Override    public ObjectMapper getContext(Class<?> type) {        ObjectMapper result = new ObjectMapper();        result.configure(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);        return result;    }}

For jackson 1.9x及更高版本，你可以使用对象映射器提供程序忽略未知属性

@Provider@Componentpublic class JerseyObjectMapperProvider implements ContextResolver<ObjectMapper> {    @Override    public ObjectMapper getContext(Class<?> type) {        ObjectMapper result = new ObjectMapper();        result.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);        return result;    }}

Spring不会自动发现Jersey类。必须手动注册。

public class JerseyConfig extends ResourceConfig {    public JerseyConfig() {        register(JerseyObjectMapperProvider.class);    }}
