Bagaimana Melewati Daftar Objek Java ke Oracle Stored Procedure Menggunakan MyBatis?

Saya tidak tahu apakah Anda sudah melakukannya atau belum, tetapi Anda perlu mendefinisikan objek Oracle.

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;
/

Kemudian Anda dapat menulis penangan tipe untuk memetakan objek Java ke objek Oracle.

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);
    }
}

Kemudian jalankan prosedurnya,

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