Question

我有一个带有spring mvc的项目，我想调用方法＆＃34; setIgnorableProperties＆＃34;从MapDeserializer全局，但我不知道如何从ObjectMapper获取此类，你能帮助我吗？感谢您的建议。我看到了，就像那样：

@Override
public void extendMessageConverters(List<HttpMessageConverter<?>> converters) {
    mapDeserializer.getContentType();
    converters.forEach(httpMessageConverter -> {
        if (httpMessageConverter instanceof MappingJackson2HttpMessageConverter) {
            MappingJackson2HttpMessageConverter converter = (MappingJackson2HttpMessageConverter) httpMessageConverter;
            ObjectMapper mapper = converter.getObjectMapper();
            MapDeserializer mapDes = mapper.(What I have to invoke?) ;
            mapDes.setIgnorableProperties({"@id", "@ref"});
        }
    });
}

该属性不是直接配置的;您需要对from cycler import cycler my_cycle = (cycler('lw', [1, 3] * cycler('color', ['b', 'g', 'r', 'c', 'm', 'y', 'k'])) fig, ax = plt.subplots() for sty, data in zip(my_cycle(), my_data): ax.plot(x, data, **sty) - 值属性使用@JsonIgnoreProperties注释。如果需要，您可以通过以下方式创建便利注释：

Map

然后使用like：

@Retention(RetentionPolicy.RUNTIME) // IMPORTANT
@JacksonAnnotationsInside
@JsonIgnoreProperties({ "@id", "@ref" })
public @interface MapIgnorals

配置内置Jackson MapDeserializer
