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     AND d.xtype= 'U'     AND d.name<> 'dtproperties'    LEFT JOIN syscomments e ON a.cdefault= e.id    LEFT JOIN sys.extended_properties g ON a.id= g.major_id     AND a.colid= g.minor_id    LEFT JOIN sys.extended_properties f ON d.id= f.major_id     AND f.minor_id= 0 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    a.id,    a.colorder;

查问后果:
