code: public SqlBuilder where(final Collection<Condition> cons) {
      conditions.addAll(cons);
      return params(Conditions.getParamMap(cons));
    }
docs: 添加一组条件<br>
  query中不能添加条件集合作为一个条件,因此这里命名没有采用有区别性的addAll
  
  @param cons a {@link java.util.Collection} object.
  @return a {@link org.beangle.commons.dao.query.builder.SqlBuilder} object.
