springboot mybatis 动态传表名和条件查询数据

id 为主键

Map<String, Object> findByTableAndId(@Param("tableName")String tableName,@Param("id")String id);

<select id="findByTableAndId" resultType="java.util.Map" parameterType="java.lang.String">
     select * from${tableName} where id = #{id}
 </select>

标红的需要注意 #{} 和${}区别
