Hur skickar jag Java List of Objects till Oracle Stored Procedur med MyBatis?

Jag kan inte säga om du redan gör det eller inte, men du måste definiera Oracle-objekt.

CREATE OR REPLACE TYPE SCHEMA."YOUR_OBJECT" AS OBJECT
(
    field_one    varchar2(50),
    field_two    varchar2(100)
);
/
CREATE OR REPLACE TYPE SCHEMA."YOUR_OBJECT_ARRAY" AS TABLE OF YOUR_OBJECT;
/

Sedan kan du skriva typhanterare för att mappa Java-objekten till Oracle-objekten.

import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;
import oracle.sql.STRUCT;
import oracle.sql.StructDescriptor;
....
public class YourTypeHandler implements TypeHandler
{
....
    public void setParameter(PreparedStatement ps, int i, Object parameter, JdbcType jdbcType) throws SQLException
    {
        List<YourObject> objects = (List<YourObject>) parameter;

        StructDescriptor structDescriptor = StructDescriptor.createDescriptor("YOUR_OBJECT", ps.getConnection());

        STRUCT[] structs = new STRUCT[objects.size()];
        for (int index = 0; index < objects.size(); index++)
        {
            YourObject pack = packs.get(index);
            Object[] params = new Object[2];
            params[0] = pack.getFieldOne();
            params[1] = pack.getFieldTwo();
            STRUCT struct = new STRUCT(structDescriptor, ps.getConnection(), params);
            structs[index] = struct;
        }

        ArrayDescriptor desc = ArrayDescriptor.createDescriptor("YOUR_OBJECT_ARRAY", ps.getConnection());
        ARRAY oracleArray = new ARRAY(desc, ps.getConnection(), structs);
        ps.setArray(i, oracleArray);
    }
}

Anropa sedan proceduren,

call your_proc
(
#{yourObjects, javaType=Object, jdbcType=ARRAY, jdbcTypeName=YOUR_OBJECT_ARRAY, mode=IN, typeHandler=YourObjectArrayTypeHandler}
)
