Generic DAO Patternを使わずにのアーキテクチャを設計したいhibernate。
GenericSpringDAOImpl<DomainObject>現在、 Javaファイルの開発に問題があります。なしで、またはのを使用してジェネリックメソッド（オブジェクトgetList()を返す）を作成する方法は？DomainObjecthibernatejdbctemplatespring
私のコードは以下の通りです：
GenericDAO.java
public interface GenericDAO<DomainObject extends Serializable, KeyType extends Serializable> extends Serializable{
/**
* Give list of all entities of underlying Domain Object.
* @return List of all entities.
*/
public List<DomainObject> getList();
/**
* Returns the total number of Entities that is affected by sql query,.
*
* @param query
* the query
* @return Number of Entities affected By SQL Query.
*/
public int getRecordBySQLQuery(String query);
/**
* Returns Domain object whose Key-value pair matched.
* @param keyName Column name
* @param keyValue any value that is being matched under Column name.
* @return DomainObject
*/
public DomainObject getRecordByKeyandValue(String keyName,Object keyValue);
public DomainObject getRecordByKeysAndValues(String[] keyName,Object[] keyValue);
/**
* Returns list of Domainobjects whose Key-value pair matched.
* @param colname Column name
* @param keyValue List of values.
* @return List<DomainObject> according to the Condition satisfied.
*/
public List<DomainObject> getListByKeyandValue(String colname,List<? extends Object> keyValue);
/**
* Returns the list of Entities according to the condition applied.
* @param condition Condition
* @return List<DomainObject> according to condition satisfied.
*/
public List<DomainObject> getListByCondition(String condition);
/**
* Find Object based on primary key.
* @param id Identifier value is passed.
* @return DomainObject i.e POJO which has the passed id value.
*/
public DomainObject getRecordByPrimaryKey(KeyType id);
/**
* get the list of primary keys based on the condition.
* @param condition Condition
* @return List<KeyType> of Primary Keys according to the Condition.
*/
public List<KeyType> getPrimaryKeyCollection(String condition);
/**
* get the list of primary keys based on the condition.
* @param condition Condition
* @return List<KeyType> of Primary Keys according to the Condition.
*/
public List<KeyType> getPrimaryKeyCollection(String condition,final Object... values);
/**
* Insert the Domain Object that is going to persist into the Database.
* @param object Domain Object which is going to persist into the Database
* @return KeyType Serializable value generated By Hibernate due to session.save().
*/
public KeyType insert(DomainObject object);
/**
* Update the Domain Object.
* @param object Domain Object that is being changed/updated.
* @return 1 if Domain Object is being successfully updated
* 0 if Exception Generation while updating the Object.
*/
public int update(DomainObject object);
/**
* Deleting Domain Object.
*
* @param object
* Domain Object that is going to be delete.
* @return the int
*/
public int delete(DomainObject object);
/**
* Delete Object whose oid(Object Identifier) matched with given Primary Key.
* @param id Identifier value.
*/
public void deleteById(KeyType id);
}
GenericSpringDAOImpl.java
public abstract class GenericDAOSpringImpl<DomainObject extends Serializable, KeyType extends Serializable> implements Serializable, GenericDAO<DomainObject, KeyType>{
@Autowired
private NamedParameterJdbcTemplate jdbcTemplate;
RowMapper<DomainObject> rowMapper;
public NamedParameterJdbcTemplate getJdbcTemplate() {
return jdbcTemplate;
}
public void setJdbcTemplate(NamedParameterJdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}
public List<DomainObject> getList(){
/*Develop Code which return DomainObjects
* One way is pass query to getList() but not good approch
*/
return new ArrayList<DomainObject>();
}
/*
Other methods also required to implements.
*/
}
