你如何用JDBI做一個通用插入？

Question

我使用JDBI與MySQL和我有一個接口GenericDao在那裏我已經這個方法

public void insert(T entity); 

如何使用流利的查詢，而不是SQLObjects實現此方法與JDBI？

是否可以使用這兩種方法之一？

handle.insert 

或

handle.createQuery 

Answer 1

您可以通過實現GetHandle接口得到處理。

public abstract class GenericDao<T> implements GetHandle { 

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

} 

Answer 2

我發現SQLObjects當我用SQLObjects風格的工作很好，我：

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

然後我用一個抽象類將所有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(); 
} 

也許這會爲某人提供解決方案。
