Contrioller:

        List<Article> list = bizService.selectxianshi();
        String data = JSON.toJSONString(list);
        return data;
    }

SQL:

<select id="selectxianshi" resultType="net.aexit.inner.aexithome.common.model.Article">
        SELECT
            CASE
            WHEN a.flag = 0 THEN '可见'
            WHEN a.flag = 1 THEN '不可见'
            END AS tt,
            COUNT(a.flag) AS num
            FROM article a
