我有一個JSON,我想使用Autobean解析。我得到的NullPointerException在for循環中,可能persons.getPersons()使用Autobean解析JSON數組
AppAutoBeanFactory factory = GWT.create(AppAutoBeanFactory.class);
AutoBean<PersonsWrapper> bean =AutoBeanCodex.decode(factory, PersonsWrapper.class, "{\"persons\": " + strResponse + "}");
IPersons persons = bean.as().getPersons();
for (IPerson person : persons.getPersons()) {
...
}
我AppAutoBeanFactory看起來是這樣的:
interface AppAutoBeanFactory extends AutoBeanFactory {
AutoBean<IPerson> person();
AutoBean<IPersons> ipersons();
AutoBean<PersonsWrapper> persons();
}
的JSON(可變strResponse)看起來是這樣的:
[
{
"name":"John",
"surname":"Blue",
"records":[10.5, 12.5, 18.6]
},
{
"name":"Steven",
"surname":"Green",
"records":[11.5, 15.5, 14.6]
}
]
我製作了這些接口:
public interface PersonsWrapper {
IPersons getPersons();
}
public interface IPersons {
void setPersons(List<IPerson> persons);
List<IPerson> getPersons();
}
public interface IPerson {
String getName();
void setName(String name);
String getSurname();
void setSurname(String surname);
}
我該如何讓它工作?以及如何將記錄數組添加到IPerson?
