MYSQL通过Example来拼接表名称查询

StringBuilder tableName = new StringBuilder();
        //拼接表名
        tableName.append(TdwTableNameEnums.GNSS.getValue());
        tableName.append("_").append(appCategory.getDictCode());
        tableName.append("_").append(nowTime.getYear()).append(String.format("%02d", nowTime.getMonthValue()));
        //判断表是否存在
        if (!dtCommonService.whetherExistsTableName(tableSchema, tableName.toString())) {
            return debugInfoVOList;
        }
        //封装查询条件
        TDtGnssExample gnssExample = new TDtGnssExample(tableName.toString());
        TDtGnssExample.Criteria criteria = gnssExample.createCriteria();
        criteria.andAnchorIdEqualTo(monitorAnchor.getAnchorId());
        criteria.andTimestampGreaterThanOrEqualTo(startTime);
        criteria.andTimestampLessThanOrEqualTo(nowTime);
        gnssExample.setOrderByClause("timestamp");
//按月查询不同月份的表数据
List<TDtGnss> tDtGnsses = dtGnssService.selectByExample(gnssExample);

//也可以通过${}直接拼接在表名称后面
select count(*) from t_dt_sensor${tableName}
