public interface Level1Mapper extends BaseMapper<Level1> { @Select("select * from a_level1 limit #{limit}") Cursor<Level1> scan(@Param("limit") int limit); }
@GetMapping("/level1s_cursor/{limit}") @Transactional(readOnly = true) public void level1sCursor(@PathVariable("limit") int limit) throws IOException { try (Cursor<Level1> cursor = level1Mapper.scan(limit)){ cursor.forEach(i->log.debug(JSON.toJSONString(i))); } }
mybaits 流式查询已经很简洁了
