How to fix 'com.fasterxml.jackson.databind.JsonMappingException: Problem deserializing property' error

I am converting date string in format yyyy-MM-dd to com.datastax.driver.core.LocalDate using object mapper and save that data into Cassandra in my java spring boot project. The type of my column in Cassandra is date and i am using com.datastax.driver.core.LocalDate in my java class. But while converting map to my java class it throws error "com.fasterxml.jackson.databind.JsonMappingException: Problem deserializing property 'employeedateofbirth' (expected type: [simple type, class com.datastax.driver.core.LocalDate]; actual type: java.time.LocalDate), problem: argument type mismatch". I am not using java.time.LocalDate still it gives me argument mismatch error.

I even tried registering module by using the following code 

ObjectMapper oMapper = new ObjectMapper().registerModule(new ParameterNamesModule()).registerModule(new Jdk8Module()).registerModule(new JavaTimeModule());
oMapper.findAndRegisterModules();

I have also tried some configuration for object mapper like 

oMapper.configure(MapperFeature.USE_GETTERS_AS_SETTERS, false) ;

Even used annotation on my attribute:

@JsonDeserialize(using = LocalDateDeserializer.class)
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE)
@JsonFormat(pattern = "yyyy-MM-dd")
private LocalDate employeedateofbirth;

But nothing seems to work for me. Any help would be appreciated. Thanks in advance.

As the error message indicates, there is a type mismatch. Change this in your target class:

import com.datastax.driver.core.LocalDate;

into:

import java.time.LocalDate;
