CodePudding user response：

You appear to have a typo in the name of the Jackson mapper property:

spring.jackson.mapper.default-view-inclusions=true

It should be "inclusion", not "inclusions":

spring.jackson.mapper.default-view-inclusion=true

CodePudding user response：

Try using the constant name: spring.jackson.mapper.DEFAULT_VIEW_INCLUSIONS=true

Expanding a bit: the spring.jackson.mapper configuration is a Map<MapperFeature, Boolean>, see https://github.com/spring-projects/spring-boot/blob/main/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/jackson/JacksonProperties.java#L77. There is no special magic for converting strings to MapperFeature constants other than MapperFeature.valueOf, so that means you need to use the actual constant name. The same goes for the other maps.
