The problem was, that the DTO which contained the LocalDateTime field was populated via reflection, and it seems possible to successfully set a value of type String. Then I try to write unit test, obtain MvcResult and with use of ObjectMapper convert it to my DTO object. e. * values if no explicit value serializer/deserializer found (which implies Java 8 date/time module is not registered). Also I set CustomObjectMapper in the spring configuration, so every time jackson wants to serialize or deserialize, my CustomObjectMapper works and everything is right. Spring Boot uses jackson by default to serialize, deserialize json data. I use SpringBoot version 2. Cannot deserialize value of type `java. 1 fixes the issue, so existing usage now works again: not recommended, but supported. With 'normal' dates I have no problem, but the LocalDateTime fields are converted to the ("com. 9. 12. this answer doesn't work for me Jackson version 2. This is useful if we want to add additional information which is not included in the source JSON. 12 added a safety feature #2683 which will block attempts to read/write java. 1.

Cons of not using explicit format is sometimes while upgrading the libraries for jackson code breaks because of change in the format for some versions. ObjectMapper is one of the most commonly used classes in the Jackson library for fast conversion between Java objects and JSON strings. 5, an elegant way to solve that is using the TypeFactory. properties file using spring. DateTimeFormatter f) Using this annotation lets us automatically configure the generated builder class to work with Jackson’s deserialization.
