ormlite

问题 I apologize if I'm not super clear with my explanation but I'll add to and edit this question for clarity if requested. I am developing an Android app which receives data through an external API and stores data locally using ORMLite. Prior to storing data locally and using ORMLite I had models which retrieved JSON from the server and parsed it via: Gson gson = new Gson(); String result = ApiClient.httpPost("/user_route"); User user = gson.fromJson(result, User.class); The User class was

问题 I am using Android with ORMLite in a small app I am currently writing. The app aims to have a working Import/Export function, for which I use Simple XML framework. And everything works great, up to a point. The situation is as follows: Object A contains a foreign key referencing Object B, which references Object C through a foreign key itself. Exporting a database is great. Importing works to, with a small caveat, namely that it works as long as the IDs of all object are sequential and start

问题 I have this error when I run my Android application: No fields have a DatabaseField annotation in class [[Lmodel.Vak; My class Vak has annotations, so I really don't understand why it still giving me this error. package model; import com.j256.ormlite.field.DatabaseField; import com.j256.ormlite.table.DatabaseTable; @DatabaseTable(tableName = "vak") public class Vak { @DatabaseField(generatedId = true, columnName = "vakID", id=true) Long id; @DatabaseField int rij; @DatabaseField int kolom; ..

I've my object named Zone : public class Zone implements Serializable { private static final long serialVersionUID = 1L; public static final String ZONE_ID = "id"; public static final String ZONE_PARENT_ID = "parentZoneId"; @DatabaseField(generatedId=true) private int id; @DatabaseField() String name;

问题 I have a SQLite table (on Android) that has numerous fields, but certain fields are repeated/denormalized. I would like to select a distinct set of this data and use them as actual objects. Example books table title summary author Little Johnny A funny kid Johnny Himself Big Johnny A funny adult Johnny Himself I would like to extract one author from this list ("Johnny Himself") and would expect I should be able to do this with ORMLite instead of manually with Java. 回答1: I would like to select

问题 I'm using RoboSpice with Spring for Android and would like to persist a JSON array of objects with OrmLite. GSON is used for the JSON marshalling. With the default caching everything works as expected. But OrmLite doesn't seem to like the array of objects. This is a simplified version of the JSON: [{"id": 1, "title": "Test 1"},{"id": 2, "title": "Test 3"},{"id": 3, "title": "Test 3"}] I would like to persist this in the following object: @DatabaseTable public class Foo { @DatabaseField(id =

问题 I'm using ORMLite in my Android project. I know that Sqlite takes care of the file level locking. Many threads can read, one can write. Locks prevent more than one writing. Could anybody please explain what will happen in case one thread is updating some record and another thread is trying to read this record?
