Я хочу добавить сгенерированный Pojo в базу данных, используя DAO. Но я получаю исключение и понятия не имею, как его решить.
Я пытался добавить Public.Troop перед каждой таблицей.
Вставка отряда в использование DAO:
TroopDao dao = new TroopDao(new DefaultConfiguration().set(SQLDialect.SQLITE).set(database.getConnection()));
Troop initial = new Troop(1, 100, 120, 120.2, 11.2, 12.0, 13.0, 6245.0, 1534.0, 1364.0, 121235.3, 125.3, 51.3);
dao.insert(initial);
Используемый файл базы данных:
CREATE TABLE IF NOT EXISTS TROOP(
id INTEGER PRIMARY KEY AUTOINCREMENT,
current_health INTEGER NOT NULL,
max_health INTEGER NOT NULL,
pos_x DOUBLE NOT NULL,
pos_y DOUBLE NOT NULL,
normal_speed DOUBLE NOT NULL,
street_speed DOUBLE NOT NULL,
difficult_terrain_speed DOUBLE NOT NULL,
close_combat_range DOUBLE NOT NULL,
ranged_combat_range DOUBLE NOT NULL,
normal_view_distance DOUBLE NOT NULL,
disadvantaged_view_distance DOUBLE NOT NULL,
advantaged_view_distance DOUBLE NOT NULL
);
CREATE TABLE IF NOT EXISTS ARMY(
id INTEGER,
hq INTEGER,
troop INTEGER,
FOREIGN KEY(hq) REFERENCES TROOP(id),
FOREIGN KEY(troop) REFERENCES TROOP(id),
UNIQUE(hq, troop),
PRIMARY KEY (id, hq, troop)
);
Поколение JOOQ, я также попытался unqualifiedSchema = main:
Configuration configuration = new Configuration()
.withGenerator(new Generator()
.withDatabase(new Database()
.withName("org.jooq.meta.extensions.ddl.DDLDatabase")
.withIncludes("ARMY | TROOP")
.withOutputSchemaToDefault(Boolean.TRUE)
.withProperties(new Property()
.withKey("unqualifiedSchema")
.withValue("none"),
new Property()
.withKey("scripts")
.withValue("/db/schema.sql")))
.withGenerate(new Generate()
.withPojos(Boolean.TRUE)
.withDeprecationOnUnknownTypes(Boolean.FALSE)
.withImmutableInterfaces(Boolean.TRUE)
.withDaos(Boolean.TRUE))
.withTarget(new Target()
.withPackageName("me.leslie.generals.server.persistence.jooq")
.withDirectory("Generals-Server/src/main/java")));
GenerationTool.generate(configuration);
Класс базы данных просто синглтон, который возвращает основное соединение с базой данных:
@EqualsAndHashCode
@ToString
@Getter
public class Database {
public static final String DEFAULT_DB_URL = "jdbc:sqlite:";
@NonNull
private final String url;
private final Connection connection;
private static Database instance;
public static Database get() {
if(instance == null){
instance = new Database(DEFAULT_DB_URL);
}
return instance;
}
private Database(String url) {
try {
this.connection = DriverManager.getConnection(url);
} catch (SQLException e) {
throw new InitializationException("Could not get Database connection", e);
}
initialize();
this.url = url;
}
private void initialize() {
final String troopSchema = "CREATE TABLE IF NOT EXISTS TROOP(" +
"id INTEGER PRIMARY KEY AUTOINCREMENT," +
"current_health INTEGER NOT NULL," +
"max_health INTEGER NOT NULL," +
"pos_x DOUBLE NOT NULL," +
"pos_y DOUBLE NOT NULL," +
"normal_speed DOUBLE NOT NULL," +
"street_speed DOUBLE NOT NULL," +
"difficult_terrain_speed DOUBLE NOT NULL," +
"close_combat_range DOUBLE NOT NULL," +
"ranged_combat_range DOUBLE NOT NULL," +
"normal_view_distance DOUBLE NOT NULL," +
"disadvantaged_view_distance DOUBLE NOT NULL," +
"advantaged_view_distance DOUBLE NOT NULL" +
");";
final String armySchema = "CREATE TABLE IF NOT EXISTS ARMY(" +
"id INTEGER," +
"hq INTEGER," +
"troop INTEGER," +
"FOREIGN KEY(hq) REFERENCES TROOP(id)," +
"FOREIGN KEY(troop) REFERENCES TROOP(id)," +
"UNIQUE(hq, troop)," +
"PRIMARY KEY (id, hq, troop)" +
");";
try (PreparedStatement sql = connection.prepareStatement(troopSchema)) {
sql.execute();
} catch (SQLException e) {
throw new InitializationException("Could not initialize Troops", e);
}
try (PreparedStatement sql = connection.prepareStatement(armySchema)) {
sql.execute();
} catch (SQLException e) {
throw new InitializationException("Could not initialize Armies", e);
}
}
}
Ошибка, когда я использую БД на основе файлов и получаю к ней доступ, кажется, что там есть необходимые таблицы:
