Mybatis中模糊查询 like 语句该怎么写?

string wildcardname = “smi”;
        list<name> names = mapper.selectlike(wildcardname);
    <select id=”selectlike”>
    select * from foo where bar like "%"#{value}"%"
</select>

string wildcardname = “%smi%”;
        list<name> names = mapper.selectlike(wildcardname);
    <select id=”selectlike”>
    select * from foo where bar like #{value}
</select>
