Java class from json with same name -
i have json object following:
... { "url": "checkout.bodenusa.com/en-us" }, { "url": [ ".bonton.com/checkout/", ".bonton.com/checkoutview" ] } ... how should java class response server.
i try snippet, incorrect:
@serializedname("url") @expose private list<string> urllist = null; @serializedname("url") @expose private string url;
create model
import com.google.gson.annotations.expose; import com.google.gson.annotations.serializedname; import java.util.list; public class model { @serializedname("url") @expose private list<string> url = null; @serializedname("apply") @expose private apply apply; @serializedname("controls") @expose private controls controls; @serializedname("remove") @expose private remove remove; public list<string> geturl() { return url; } public void seturl(list<string> url) { this.url = url; } public apply getapply() { return apply; } public void setapply(apply apply) { this.apply = apply; } public controls getcontrols() { return controls; } public void setcontrols(controls controls) { this.controls = controls; } public remove getremove() { return remove; } public void setremove(remove remove) { this.remove = remove; } public class controls { @serializedname("promo") @expose private string promo; @serializedname("total") @expose private string total; @serializedname("ordertotal") @expose private string ordertotal; @serializedname("coupon") @expose private string coupon; public string getpromo() { return promo; } public void setpromo(string promo) { this.promo = promo; } public string gettotal() { return total; } public void settotal(string total) { this.total = total; } public string getordertotal() { return ordertotal; } public void setordertotal(string ordertotal) { this.ordertotal = ordertotal; } public string getcoupon() { return coupon; } public void setcoupon(string coupon) { this.coupon = coupon; } } public class remove { @serializedname("type") @expose private string type; @serializedname("submit") @expose private string submit; @serializedname("timeout") @expose private integer timeout; public string gettype() { return type; } public void settype(string type) { this.type = type; } public string getsubmit() { return submit; } public void setsubmit(string submit) { this.submit = submit; } public integer gettimeout() { return timeout; } public void settimeout(integer timeout) { this.timeout = timeout; } } public class apply { @serializedname("type") @expose private string type; @serializedname("submit") @expose private string submit; @serializedname("timeout") @expose private integer timeout; public string gettype() { return type; } public void settype(string type) { this.type = type; } public string getsubmit() { return submit; } public void setsubmit(string submit) { this.submit = submit; } public integer gettimeout() { return timeout; } public void settimeout(integer timeout) { this.timeout = timeout; } } } use class along custom typeadapter gson .then work both list , object response .
arrayadapter class
import com.google.gson.gson; import com.google.gson.typeadapter; import com.google.gson.typeadapterfactory; import com.google.gson.reflect.typetoken; import java.lang.reflect.parameterizedtype; import java.util.arraylist; import java.util.list; public class arrayadapterfactory implements typeadapterfactory { @override @suppresswarnings({"unchecked", "rawtypes"}) public <t> typeadapter<t> create(final gson gson, final typetoken<t> type) { typeadapter<t> typeadapter = null; try { if (type.getrawtype() == list.class || type.getrawtype() == arraylist.class) { typeadapter = new arrayadapter(gson, (class) ((parameterizedtype) type.gettype()) .getactualtypearguments()[0]); } } catch (exception e) { e.printstacktrace(); } return typeadapter; } } arrayadapterfactory class
import com.google.gson.gson; import com.google.gson.typeadapter; import com.google.gson.stream.jsonreader; import com.google.gson.stream.jsontoken; import com.google.gson.stream.jsonwriter; import java.io.ioexception; import java.util.arraylist; import java.util.list; class arrayadapter<t> extends typeadapter<list<t>> { private class<t> adapterclass; private gson gson; public arrayadapter(gson gson, class<t> adapterclass) { this.adapterclass = adapterclass; this.gson = gson; } @override public list<t> read(jsonreader reader) throws ioexception { list<t> list = new arraylist<t>(); final jsontoken token = reader.peek(); system.out.println(token); // handling of scenario 2( check javadoc class) : if (token == jsontoken.string || token == jsontoken.number || token == jsontoken.boolean) { t inning = (t) gson.fromjson(reader, adapterclass); list.add(inning); } else if (token == jsontoken.begin_object) { // handling of scenario 1(check javadoc class) : t inning = (t) gson.fromjson(reader, adapterclass); list.add(inning); } else if (token == jsontoken.begin_array) { reader.beginarray(); while (reader.hasnext()) { @suppresswarnings("unchecked") t inning = (t) gson.fromjson(reader, adapterclass); list.add(inning); } reader.endarray(); } return list; } @override public void write(jsonwriter writer, list<t> value) throws ioexception { } } and register adapter factory this,
gson gson = new gsonbuilder().registertypeadapterfactory(new arrayadapterfactory()).create();
