在 jooq 中使用 DAO 时出现 DataAccessException

Question

I want to add a Generated Pojo to the database using a DAO. But I recieve an Exception and have no clue how to solve it.

I tried adding a Public.Troop in front of every Table.

Inserting a Troop into the DAO ussage:

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);

The used Database file:

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)
);

JOOQ Generation, I also tried 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);

Databaseclass just a singleton that returns a basic DataBaseconnection:

@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(" +

        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)) {

        } catch (SQLException e) {
            throw new InitializationException("Could not initialize Armies", e);
        }
    }
}

Error, When I use a Filebased db and access it the needed tables seem to be there:

Answer 1

Per jOOQ 3.12, the DDLDatabase parses your SQL scripts, translates them to H2 and runs them against an in-memory H2 database, which uses PUBLIC as the default schema, where all your tables are now located from the viewpoint of the code generator.

Such a schema does not exist in SQLite, which is why you're getting the errors you've seen. jOOQ 3.12 has fixed this by supporting a new unqualifiedSchema property, which allows for specifying the implied schema of all unqualified tables in the DDL scripts. By default, given that this maps to PUBLIC in H2, PUBLIC is assumed as the "default schema". So, to fix this, simply upgrade to jOOQ 3.12. See more details here: https://www.jooq.org/doc/latest/manual/code-generation/codegen-ddl

Note: You're already using this flag, but you're not using jOOQ 3.12. It was not available in 3.11.11 yet.

Answer 2

In your Database class you need to provide the path to your database file.

public static final String DEFAULT_DB_URL = "jdbc:sqlite:**sqlite_database_file_path**";

For Example

jdbc:sqlite:C:/sqlite/db/LeslieDB.db
