tproductdetail表：ID、PRDTID（外键）、SPEC1ID（外键）、SPEC2ID（外键）、DCODE、QUANTITY。
tproduct 表：ID、CID、BID、SID、UID、CODE
tspc 表：ID、NAME、DISNUM、SEQ、SYSDATE、ISACTIVES、CID。
tproductdetail表中的PRDTID（外键）值对应的是tproduct的主键ID值；tproductdetail中的SPEC1ID（外键）值对应的是tspc的主键ID值，tproductdetail中的SPEC2ID（外键）值对应的是tspc的主键ID值，现在我想在jsp页面中的下拉框中查出tproductdetail的外键值，mybatis查询代码怎么写？具体怎么实现？
