spring.jackson.deserialization.USE_BIG_DECIMAL_FOR_FLOATS：true not not working

Question

使用spring.jackson.deserialization.USE_BIG_DECIMAL_FOR_FLOATS：true以保留尾随零，但遗憾的是无法正常工作。我也试过

@Bean
public Jackson2ObjectMapperBuilder jacksonBuilder() {
    Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
    builder.indentOutput(true);
    builder.featuresToEnable(DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS);
    return builder;
}

这也不起作用，indentOutput(true)工作正常，但featuresToEnable(DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS)不起作用
