### Question:
JdbcLogServiceImpl implements LogService { @Override public CommonPager<LogVO> listByPage(final ConditionQuery query) { final String tableName = RepositoryPathUtils.buildDbTableName(query.getApplicationName()); final PageParameter pageParameter = query.getPageParameter(); StringBuilder sqlBuilder = new StringBuilder(); sqlBuilder.append("select trans_id,target_class,target_method," + " retried_count,create_time,last_time,version,error_msg from ") .append(tableName).append(" where 1= 1 "); if (StringUtils.isNoneBlank(query.getTransId())) { sqlBuilder.append(" and trans_id = ").append(query.getTransId()); } final String sql = buildPageSql(sqlBuilder.toString(), pageParameter); CommonPager<LogVO> pager = new CommonPager<>(); final List<Map<String, Object>> mapList = jdbcTemplate.queryForList(sql); if (CollectionUtils.isNotEmpty(mapList)) { pager.setDataList(mapList.stream().map(this::buildByMap).collect(Collectors.toList())); } final Integer totalCount = jdbcTemplate.queryForObject(String.format("select count(1) from %s", tableName), Integer.class); pager.setPage(PageHelper.buildPage(pageParameter, totalCount)); return pager; }  @Override CommonPager<LogVO> listByPage(final ConditionQuery query); @Override Boolean batchRemove(final List<String> ids, final String appName); @Override Boolean updateRetry(final String id, final Integer retry, final String appName); void setDbType(final String dbType);  }### Answer:
@Test public void listByPage() throws Exception { ConditionQuery query = new ConditionQuery(); PageParameter pageParameter = new PageParameter(1,10); query.setPageParameter(pageParameter); query.setApplicationName("account-service"); final CommonPager<LogVO> pager = logService.listByPage(query); Assert.assertNotNull(pager.getDataList()); }
