Question

我正在使用JDBI和MySQL，我有一个接口GenericDao，我有这个方法

public void insert(T entity);

如何使用Fluent查询而不是SQLObjects来实现JDBI的此方法？

是否可以使用其中任何一个？

handle.insert

或

handle.createQuery

Answer 1

我发现当我使用SQLObjects样式时，SQLObjects对我很有用：

public interface GenericDao<T> {
    List<T> findAll();
    long insert(T t);
    long update(T t);
    long delete(long id);
    T findNameById(long id);
}

然后我使用了一个抽象类来放入所有SQL

@RegisterMapper(VesselJDBIMapper.class)
public abstract class VesselJDBI implements Transactional<VesselJDBI>, GenericDao<Vessel> {

    @SqlUpdate("UPDATE vessel SET vessel_name = :vesselName, version = version +1 WHERE vessel_id = :id" +
            " AND version = :version")
    public abstract long update(@BindBean Vessel vessel);

    @SqlUpdate("DELETE FROM vessel WHERE vessel_id = :id")
    public abstract long delete(@Bind("id") long id);

    @SqlQuery("SELECT vessel_id, vessel_name, version FROM vessel WHERE vessel_id = :id")
    public abstract Vessel findNameById(@Bind("id") long id);

    @SqlUpdate("INSERT INTO vessel (vessel_name, version) VALUES (:vesselName, :version)")
    @GetGeneratedKeys
    public abstract long insert(@BindBean Vessel vessel);

    @SqlQuery("SELECT vessel_id, vessel_name, version FROM vessel ORDER BY vessel_id")
    public abstract List<Vessel> findAll();
}

也许这会为某人提供解决方案。

您可以通过实现GetHandle接口来处理。

public abstract class GenericDao<T>  implements GetHandle {

    public void insert(T entity) {
        getHandle().insert("some sql");
    };

}

你如何使用JDBI进行通用插入？
