pagehelper:
# dialect: ①
# 分页插件会自动检测当前的数据库链接,自动选择合适的分页方式(可以不设置)
helper-dialect: mysql
# 上面数据库设置后,下面的设置为true不会改变上面的结果(默认为true)
auto-dialect: true
page-size-zero: false # ②
reasonable: true # ③
# 默认值为 false,该参数对使用 RowBounds 作为分页参数时有效。(一般用不着)
offset-as-page-num: false
# 默认值为 false,RowBounds是否进行count查询(一般用不着)
row-bounds-with-count: false
#params: ④
#support-methods-arguments: 和params配合使用,具体可以看下面的讲解
# 默认值为 false。设置为 true 时,允许在运行时根据多数据源自动识别对应方言的分页
auto-runtime-dialect: false # ⑤
# 与auto-runtime-dialect配合使用
close-conn: true
# 用于控制默认不带 count 查询的方法中,是否执行 count 查询,这里设置为true后,total会为-1
default-count: false
#dialect-alias: ⑥
@Override
public PageInfo queryFollowmeBasicInfo(int pageNum, int pageSize) {
PageHelper.startPage(pageNum, pageSize, true);
List<Map<String, Object>> mapList = followMeMapper.queryFollowmeBasicInfo();
mapList.forEach(map -> {
String equity = map.get("equityData").toString();
JSONArray array = JSON.parseArray(equity);
List<Map> list = JSON.parseArray(array.toJSONString(), Map.class);
List<Map<String, Object>> listE = MapConvert.listMapConvert(list);
map.put("equityData", listE);
String deposit = map.get("depositWithdraw").toString();
JSONArray array1 = JSON.parseArray(deposit);
List<Map> list1 = JSON.parseArray(array1.toJSONString(), Map.class);
List<Map<String, Object>> listD = MapConvert.listMapConvert(list1);
map.put("depositWithdraw", listD);
});
PageInfo pageInfo = new PageInfo(mapList);
return pageInfo;
}
首先使用:PageHelper.startPage(pageNum, pageSize, true);
一定要带true,此时会有总条数,总页数等信息
