Java DeserializerFactoryConfig-class And Method Code Example
Here is an example of using the DeserializerFactoryConfig
class from the com.fasterxml.jackson.databind package in the Jackson library for Java:
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.cfg.DeserializerFactoryConfig;
public class Example {
public static void main(String[] args) {
// create a new ObjectMapper
ObjectMapper mapper = new ObjectMapper();
// get the DeserializerFactoryConfig of the mapper
DeserializerFactoryConfig factoryConfig = mapper.getDeserializationConfig().getDeserializerFactoryConfig();
// configure the factory to disable the use of Java 8 time types
factoryConfig.without(DeserializationFeature.USE_BIG_DATE_FOR_DATES);
// example input JSON string
String jsonInput = "{\"date\":\"2022-01-01\"}";
try {
// use the ObjectMapper to deserialize the input JSON to a MyData object
MyData data = mapper.readValue(jsonInput, MyData.class);
System.out.println("MyData: " + data);
} catch (IOException e) {
e.printStackTrace();
}
}
}
class MyData {
private java.util.Date date;
public java.util.Date getDate() {
return date;
}
public void setDate(java.util.Date date) {
this.date = date;
}
@Override
public String toString() {
return "MyData [date=" + date + "]";
}
}
This example uses the DeserializerFactoryConfig
class to configure the deserialization factory of an ObjectMapper. It disables the use of Java 8 time types via the without(DeserializationFeature.USE_BIG_DATE_FOR_DATES) method. Then it uses the ObjectMapper to deserialize a JSON input to a MyData object.
Please note that the DeserializerFactoryConfig
class is not a public class, it is intended to be used internally by the ObjectMapper, and it's usage may change in future versions of the library.
