需要形容:不同零碎领有不同的用户表,如果新增一个零碎的话,则须要新增用户表,此时如果在页面展现的话,则会呈现问题,显得写的很死,不能灵便调用。
现想针对新增零碎用户表的时候能做动静解决,不论新增任何表,都能够动静进行查问,新增,批改,删除操作,不须要后端新增接口,进行增删改查操作。
表构造:
代码:查问,展现详情
controller:
@ApiOperation("查问啊")
@RequestMapping(value = "/personManagementDetail", method = RequestMethod.POST)
public MapOutput personManagementDetail(String userTbname, String accountNumber, Integer pageNum, Integer pageSize) {
// 查问零碎表中是否存在新增的用户表
List<EditAndUserOutputDto> editAndUserEntity = pactera_SystemService.getUserTbNameAndEdit(userTbname);
Map maps = new HashMap();
List<String> stringList = new ArrayList<>();
// 查问须要展现的用户表的表名,字段名,字段形容,用来动静展现 title 和 body
List<TitleOutput> titleOutputList = pactera_SystemService.getFieldInformation(userTbname);
List list = new ArrayList();
for (int i = 0; i < titleOutputList.size(); i++) {Map map = new HashMap<>();
map.put("key", titleOutputList.get(i).getFieldName());
map.put("name", titleOutputList.get(i).getFieldDescription());
list.add(map);
String fieldName = titleOutputList.get(i).getFieldName();
stringList.add(fieldName);
}
if (editAndUserEntity.size() == 0) {maps.put("header", list);
maps.put("body", 0);
} else {
// 当零碎表中领有此用户表时,进行查问,用来展现数据
PageInfo<Map<String, Object>> lists = userService.getBodyResult(userTbname, accountNumber, pageNum, pageSize, stringList);
List<Map<String, Object>> body = lists.getList();
maps.put("header", list);
maps.put("body", body);
}
// 0 是可编辑状态,1 是不可编辑状态
if ("User".equals(userTbname)) {maps.put("edit", 1);
} else {maps.put("edit", 0);
}
return new MapOutput(200, "胜利", null, maps);
}
对应 mapper.xml
SELECT
表名 =
CASE
WHEN a.colorder= 1 THEN
d.name ELSE ''
END, 字段序号 = a.colorder, 字段名 = a.name,
字段阐明 = ISNULL(g.[value], '' )
FROM
syscolumns a
LEFT JOIN systypes b ON a.xusertype= b.xusertype
INNER JOIN sysobjects d ON a.id= d.id

LEFT JOIN syscomments e ON a.cdefault= e.id
LEFT JOIN sys.extended_properties g ON a.id= g.major_id

LEFT JOIN sys.extended_properties f ON d.id= f.major_id

WHERE
d.name LIKE '%User' -- 如果查问所有表, 加上此条件
--d.name = 某用户表 如果只查问指定表, 加上此条件
ORDER BY

查问后果:
