Just in case that somebody hits a similiar problem where only @JsonFormat gets ignored:

Consider that in Spring Boot + Java 8 context the processing of LocalDateTime may experience troubles. Instead of following dependency:

 compile group: 'com.fasterxml.jackson.datatype', name: 'jackson-datatype-jdk8'

You should use:

 compile group: 'com.fasterxml.jackson.datatype', name: 'jackson-datatype-jsr310'

Furthermore, when you create your Jackson ObjectMapper you need to register the implementation which treats LocalDateTime correctly:

 json = new ObjectMapper().findAndRegisterModules().writeValueAsString(entity);
 new ObjectMapper().findAndRegisterModules().readValue(json, entity.getClass());
