and, last 1 thing, sorry english.
you can use jackson task easy.
add following dependencies
<dependency> <groupid>org.codehaus.jackson</groupid> <artifactid>jackson-core-asl</artifactid> <version>1.9.9</version> </dependency> <dependency> <groupid>org.codehaus.jackson</groupid> <artifactid>jackson-mapper-asl</artifactid> <version>1.9.9</version> </dependency>
create pojo class corresponding json fields
in class loading json data add following:-
import org.codehaus.jackson.jsonparser;
import org.codehaus.jackson.map.objectmapper;
and
objectmapper mapper = new objectmapper(); mapper.configure(jsonparser.feature.allow_comments, true); mapper.configure(org.codehaus.jackson.map.deserializationconfig.feature.fail_on_unknown_properties, true);
pojoclass[] jsonrecords = mapper.readvalue(jsonfile, pojoclass);
