Spring 4.2.3 and fasterxml Jackson 2.7.0 are incompatible
Support for Jackson 2.7 will be added in Spring 4.3. See https://jira.spring.io/browse/SPR-13483.
For now you aren't able to use it without providing your own integration classes.
The best compatible versions
1)Spring 4.2.4 works with fasterxml Jackson 2.7.2 or 2.8.4
2)Spring 4.3.5 works with fasterxml Jackson 2.7.0
