Java NioPathDeserializer-class And Method Code Example
Here is an example of how to use the NioPathDeserializer class in the com.fasterxml.jackson.databind package to deserialize a JSON string into a java.nio.file.Path object:
import com.fasterxml.jackson.databind.ObjectMapper;
import java.nio.file.Path;
public class Example {
public static void main(String[] args) throws Exception {
String json = "{\"path\":\"/tmp/example.txt\"}";
ObjectMapper mapper = new ObjectMapper();
PathWrapper wrapper = mapper.readValue(json, PathWrapper.class);
Path path = wrapper.getPath();
// Use the Path object as needed
System.out.println(path);
}
}
class PathWrapper {
private Path path;
public PathWrapper() {}
public Path getPath() {
return path;
}
public void setPath(Path path) {
this.path = path;
}
}
In this example, an instance of the ObjectMapper class is used to deserialize the JSON string into an instance of the PathWrapper class, which contains a Path field. The readValue() method is used to deserialize the JSON string into an instance of the PathWrapper class.
It's important to notice that this is a basic example, the NioPathDeserializer is not a class that you need to instantiate, it is used automatically when trying to deserialize a java.nio.file.Path object.
Also, you should be aware that the Path class is only available in Java 7 and later versions, so if you are using an older version of Java, you will need to use a different approach to work with file paths.
