I got an example how to call
oracle SP in iBATIS 3 without a map file.
And now I understand how to call it.
But I got another problem that how to get a result from output parameter(Oracle cursor).
A part of exception messages is "There is no setter for property named 'rs' in 'class java.lang.Class".
Below is my code. Does anyone can help me?
Oracle Stored Procedure:
CREATE OR REPLACE PROCEDURE getProducts
(
rs OUT SYS_REFCURSOR
)
IS
BEGIN
OPEN rs FOR
SELECT * FROM Products;
END getProducts;
Interface:
public interface ProductMapper
{
@Select("call getProducts(#{rs,mode=OUT,jdbcType=CURSOR})")
@Options(statementType = StatementType.CALLABLE)
List<Product> getProducts();
}
DAO:
public class ProductDAO
{
public List<Product> getProducts()
{
return mapper.getProducts(); // mapper is ProductMapper
}
}
