Sql是必需的错误Spring StoredProcedure

Question

当我执行下面的代码时，我正在获取属性“sql”是必需的错误。有人能帮我吗？我不知道如何在TestDAO calss中注入Datasource以使其正常工作。

public class TestDAO extends BaseStoredProcedure
{

    final protected Logger logger = Logger.getLogger(this.getClass().getName());

     private static final String SPROC_NAME = "dbo.SP1";


     @Autowired
     private JdbcTemplate jdbcTemplate;




    public java.util.ArrayList<IssuerProductResponse> validIssuersProducts(java.util.ArrayList<IssuerProductRequest> issuersProducts)
    {
        //PARAM MAP set here

        //compile SP
        HIOSBaseStoredProcedure hiosBaseSP = new HIOSBaseStoredProcedure(jdbcTemplate.getDataSource(),SPROC_NAME,inMap,null,null,null);

        //now set parameters

        Map<String, Object> result = super.execute(parameters);
        System.out.println(result);

        return liReponse;
    }


}

BaseStoreProcedure类

public class BaseStoredProcedure extends StoredProcedure {


    public BaseStoredProcedure() {
        super();
        // TODO Auto-generated constructor stub
    }

    /**
     * 
     * @param ds
     * @param spname
     * @param map
     * @param sqlOutKey
     * @param returnType
     * @param rowmapper
     */
    public BaseStoredProcedure (DataSource ds, String spname,
            Map<String, Integer> map, String sqlOutKey, Integer returnType,
            RowMapper rowmapper) {
        super();
        setDataSource(ds);

        /* resultset has to be declared first over other declare parameters */
        if (rowmapper != null) {
            declareParameter(new SqlReturnResultSet(sqlOutKey, rowmapper));
        }

        if (map != null) {
            Iterator itr = map.keySet().iterator();
            while (itr.hasNext()) {
                String key = (String) itr.next();
                Integer value = (Integer) map.get(key);
                declareParameter(new SqlParameter(key, value.intValue()));
            }
        }

        /*
         * sql out paramter has to be declared based on the order in stored
         * procedures, In all our stored procedures we have it after input
         * parameters
         */
        if (returnType != null) {
            declareParameter(new SqlOutParameter(sqlOutKey, returnType
                    .intValue()));
        }

        setSql(spname);
        compile();
    }
}
