你应该Jackson2ObjectMapperBuilderCustomizer为此使用

@Configuration
public class JacksonConfiguration {

    @Bean
    public Jackson2ObjectMapperBuilderCustomizer addCustomBigDecimalDeserialization() {
        return new Jackson2ObjectMapperBuilderCustomizer() {

            @Override
            public void customize(Jackson2ObjectMapperBuilder jacksonObjectMapperBuilder) {
               jacksonObjectMapperBuilder.featuresToDisable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
               // Add your customization
               // jacksonObjectMapperBuilder.featuresToEnable(...)      
            }
        };
    }
}
