xml:

<select id="test" resultMap="BaseResultMap">
    select
    <include refid="Base_Column_List"/>
    from ds_award_point t
    where  t.`name`=#{bandPointDO.name}
</select>

mapper:

 List test(TestDO testDO);

@data

public class TestDO { BandPointDO bandPointDO;

}

TestDO testDO=new TestDO();
BandPointDO bandPointDO=new BandPointDO();
bandPointDO.setName("001");
testDO.setBandPointDO(bandPointDO);

mapper.test(testDO)

当然了，需要对实体属性判空，然后再获取 类的属性 的属性字段

t.`name`=#{bandPointDO.name}
