一段可以使用的 hibernate获得对象->action存入List->jsp页面用<s:iterator>迭代的代码...-优快云博客

本文介绍了一个名为SelectAction的Java类，它通过SelectService接口获取报告列表，并将这些列表通过toReportGetter方法进行处理，最后在select.jsp页面上以表格形式展示出来。

SelectAction.java

10         this.selectService = selectService;
11     }

13     public List<ReportFormBeans> reportlist; 
14     public List<ReportFormBeans> getReportlist(){
15          return reportlist;
16          }
17     public void setReportlist(List<ReportFormBeans> reportlist) {
18          this.reportlist = reportlist;
19          }
20     
21     public String toReportGetter()throws Exception
22     {
23

25         
26          List<ReportFormBeans> list = new ArrayList<ReportFormBeans>();
27 
28             int i = 1;
29             int max = selectService.getReportCount();
30             
31             while(i <= max){
32                 ReportFormBeans reportFormBean = new ReportFormBeans();
33                 BeanUtils.copyProperties(reportFormBean , selectService.getReport(i));
34                 list.add(reportFormBean); 
35 
36                 for (int j = 0; j < list.size(); j++) {
37                     System.out.println(list.get(j));
38                 }
39 
40                 i++;
41             }                        
42             this.setReportlist(list);
43             return SUCCESS;            
44         } catch (Exception e) {
45             e.printStackTrace();
46             System.out.println("ERROR！");
47             return INPUT;
48         }
49     }
50 }
