上移下移操作

很想弄个上移下移操作的通用层，但是在设计的时候发现设计后整个Action代码用起来却更加的复杂。所以就先放弃掉，以后有更好的办法再将其设计一遍。现在先只能将我所写的Action粘贴过来，以后如果碰见上移下移的操作方便参照，下面的这个需要对照以前设计的通用层：

[java] view plain copy

1. public String operateClassification(){  
2.         Classification theClassification = new Classification();  
3.         //artId字段倒序方式查找整个Classification中的数据  
4.         List allList = userService.selete(null,null, "desc","Classification","artId");  
5.         //nextId是从jsp传过来的用来标识是上移还是下移操作,下面这个是上移操作  
6.         if(nextId==0){  
7.               
8.             for(int i =0;i<allList.size();i++){  
9.                   
10.                 Classification theClassification1 = (Classification)allList.get(i);  
11.                 Integer id2 = theClassification1.getArtId();  
12.                   
13.                 if(id==id2){  
14.                     System.out.println(id);  
15.                     //上一条记录  
16.                     Classification theClassification2 = (Classification)allList.get(i-1);  
17.                     int upId = theClassification2.getArtId();  
18.                     String id3 = String.valueOf(theClassification2.getId());  
19.                     String upID = String.valueOf(upId);  
20.                     //当前artId,id  
21.                     int onId = theClassification1.getArtId();  
22.                     String id4 = String.valueOf(theClassification1.getId());  
23.                     String onID = String.valueOf(onId);  
24.                     String[] array3={"ArtId"};  
25.                       
26.                     Integer[] array4 = {upId};  
27.                     Integer[] array5 ={onId};  
28.                     //靠id来查询记录然后彼此调换artId的值  
29.                     userService.edit(theClassification, "id", id3, "Classification", null, null, array3, array5, null, null);  
30.                     userService.edit(theClassification, "id", id4, "Classification", null, null, array3, array4, null, null);  
31.                       
32.                     break;  
33.                 }  
34.             }  
35.               
36.         }else{  
37.             for(int i =0;i<allList.size();i++){  
38.                 Classification theClassification1 = (Classification)allList.get(i);  
39.                   
40.                 int id2 = theClassification1.getArtId();  
41.                   
42.                 if(id==id2&i<allList.size()-1){  
43.                       
44.                     System.out.println(id+"aa");  
45.                     Classification theClassification2 = (Classification)allList.get(i+1);  
46.                     int upId = theClassification2.getArtId();  
47.                     String id3 = String.valueOf(theClassification2.getId());  
48.                     String upID = String.valueOf(upId);  
49.                     int onId = theClassification1.getArtId();  
50.                     String id4 = String.valueOf(theClassification1.getId());  
51.                     String onID = String.valueOf(onId);  
52.                     String[] array3={"ArtId"};  
53.                   
54.                     Integer[] array4 = {upId};  
55.                     Integer[] array5 ={onId};  
56.                       
57.                     userService.edit(theClassification, "id", id3, "Classification", null, null, array3, array5, null, null);  
58.                     userService.edit(theClassification, "id", id4, "Classification", null, null, array3, array4, null, null);  
59.                     //break很关键，漏了很可能出错  
60.                     break;  
61.                       
62.                 }  
63.             }  
64.   
65.         }  
66.             return "operateClassification";  
67.     }
