mybatis执行任意SQL问题

public interface SqlDao{
	@Select("${sql}")
    List<LinkedHashMap<String,Object>> 	sql(String sql,@Param("param") Map<String,Object> param);
}

Map<String,Object>  params = new HashMap<>();
//这里可加任意多参数，与SQL中对应
params.put("id","xxx");
List<LinkedHashMap<String,Object>> result = medicineboxDao.sql("select * from DevLog where id =#{param.id}",params);

public interface SqlDao{
 @Select("${sql}")
 	<S> List<S> sql2(String sql,@Param("param") Map<String,Object> param);
 }
   
//调用
List<DevLog> o2 = medicineboxDao.sql2("select * from DevLog where id =#{param.id}",params); 

//System.out.println(o2.get(0).getClass());当获得结果的CLASS对象时，报错了

 @Select({"${sql}"})
    default <S> List<S> sqlFromObject(String sql,@Param("param") Map<String,Object> param,Class<S> sc){
        final List<S> lis = new ArrayList<>();
        this.generalSql(sql, param, (ResultHandler<S>) resultContext -> {
            try {
                S s = sc.newInstance();
                //采用cglib BeanCopier，性能强劲
               //bean map拷贝
                BeanMap beanMap = BeanMap.create(s);
                beanMap.putAll((Map)resultContext.getResultObject());
                lis.add(s);
            } catch (Exception e) {
                e.printStackTrace();
            }
        });
        return lis;
    };

    @Select({"${sql}"})
    @ResultType(LinkedHashMap.class)
    <S> void generalSql(String sql, @Param("param") Map<String,Object> param, ResultHandler<S> handler) ;

 List<DevLog> o2 = medicineboxDao.sqlFromObject("select * from DevLog where id <>#{param.id}",params,DevLog.class);
