通过DEP添加的F7字段，如何在bos代码里面调用

在dep里面通过元数据检查，找到bosType参数，然后传入F7基础资料表名，以及选择的对象名称

public CoreBaseInfo getInfo(Context ctx,String bosType,String tableName,String name){

  EntityObjectInfo entityObjectInfo = MetaDataLoaderFactory.getMetaDataLoader(ctx)

  .getEntity(BOSObjectType.create(bosType));

  CoreBaseInfo  coreBaseInfo = null;

  try {

  IObjectValue objectInfo = Utils.newObjectValueInstance(entityObjectInfo);

   coreBaseInfo =(CoreBaseInfo)objectInfo;

  String sql="select fid,fname_l2 from "+tableName+" where fname_l2 ='"+name+"' and fstate=1";

  IRowSet executeQuery = DbUtil.executeQuery(ctx, sql);

  if(executeQuery.next()){

  coreBaseInfo.setId(BOSUuid.read(executeQuery.getStr
