Jackson2ObjectMapperBuilder 启用字段可见性任何 [英] Jackson2ObjectMapperBuilder enable field visibility ANY

问题描述

我正在使用 spring-boot 并且想要自定义创建的 ObjectMapper.

I'm using spring-boot and want to customize the ObjectMapper created.

我想要做的是能够序列化没有 getter 或 setter 的对象.在这之前，可以通过将 JsonAutoDetect.Visibility.ANY 放在 ObjectMapper 上来完成.

What I want to do is be able to serialize objects that do not have a getter or setters. Before this could be done by putting JsonAutoDetect.Visibility.ANY on the ObjectMapper.

但是如何使用我当前公开的 Jackson2ObjectMapperBuilder bean 启用此功能?

But how can I enable this feature using the Jackson2ObjectMapperBuilder bean I'm currently exposing ?

推荐答案

您可以使用覆盖 configure(ObjectMapper) 方法的 Jackson2ObjectMapperBuilder 子类:

You can use a Jackson2ObjectMapperBuilder subclass that overrides the configure(ObjectMapper) method:

@Bean
public Jackson2ObjectMapperBuilder objectMapperBuilder() {
    return new Jackson2ObjectMapperBuilder() {

        @Override
        public void configure(ObjectMapper objectMapper) {
            super.configure(objectMapper);
            objectMapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY);
        }

    };

}
