How to specify jackson to only use fields - preferably globally

You can configure individual ObjectMappers like this:

ObjectMapper mapper  = new ObjectMapper();mapper.setVisibility(mapper.getSerializationConfig().getDefaultVisibilityChecker()                .withFieldVisibility(JsonAutoDetect.Visibility.ANY)                .withGetterVisibility(JsonAutoDetect.Visibility.NONE)                .withSetterVisibility(JsonAutoDetect.Visibility.NONE)                .withCreatorVisibility(JsonAutoDetect.Visibility.NONE));

If you want it set globally, I usually access a configured mapper through a wrapper class.

In Jackson 2.0 and later you can simply use:

import com.fasterxml.jackson.annotation.JsonAutoDetect;import com.fasterxml.jackson.annotation.PropertyAccessor;import com.fasterxml.jackson.databind.ObjectMapper;   ...ObjectMapper mapper = new ObjectMapper();    mapper.setVisibility(PropertyAccessor.ALL, Visibility.NONE);mapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY);

to turn off autodetection.

Specifically for boolean is*() getters:

I've spend a lot of time on why neither below

  @JsonAutoDetect(fieldVisibility = Visibility.ANY, getterVisibility = Visibility.NONE, setterVisibility = Visibility.NONE)

nor this

  setVisibility(PropertyAccessor.SETTER, JsonAutoDetect.Visibility.NONE);  setVisibility(PropertyAccessor.GETTER, JsonAutoDetect.Visibility.NONE);  setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY);

worked for my Boolean Getter/Setter.

Solution is simple:

  @JsonAutoDetect(isGetterVisibility = Visibility.NONE, ...            setVisibility(PropertyAccessor.IS_GETTER, JsonAutoDetect.Visibility.NONE);

UPDATE: spring-boot allowed configure it:

jackson:  visibility.field: any  visibility.getter: none  visibility.setter: none  visibility.is-getter: none
