jpa使用like查询，需要拼接字符串，如下

oracle用法：

//dao层代码
@Query(value = "SELECT * FROM TABLENAME WHERE USER_NAME LIKE '%'||?1||'%'", nativeQuery = true)
List<Map<String, Object>> queryUserInfoByName(String userName);

 mysql用法：

//dao层代码
@Query(value = "SELECT * FROM TABLENAME WHERE USER_NAME LIKE CONCAT('%',:userName,'%')", nativeQuery = true)
List<Map<String, Object>> queryUserInfoByName(@Param("userName") String userName);
