更新時(shí)間：2013年11月15日 11:53:30 作者：

這篇文章主要是為大家介紹了jsp中通過(guò)action保存與修改的判斷方法，學(xué)習(xí)jsp的朋友可以參考下

Action中的代碼片段

復(fù)制代碼代碼如下:

private String epid;//全局變量得到的是一個(gè)以逗號(hào)分隔的字符串
public String getEpid() {
return epid;
}

public void setEpid(String epid) {
this.epid = epid;
}

public String edit() {
        try {
            if ("save".equals(save)) {//點(diǎn)擊保存按鈕的時(shí)候執(zhí)行
                return save();
            } else {
                loadInfo();
                return RETURN_EDIT;
            }
        } catch (Exception e) {
            super.printErrors(this.getRequest(), e, className);
            return RETURN_ERROR;
        }
}

private void loadInfo() throws Exception {
        epid = this.getRequest().getParameter("id");//得到單個(gè)的epid
        Long userid = getLoginUser().getUser().getUserID();
        /**
             功能:
              得到單個(gè)對(duì)象并把各個(gè)對(duì)象放到VO對(duì)象中
              頁(yè)面中顯示數(shù)據(jù)的值

**/

        Ep ep = new Ep();
        ep.setId(Long.parseLong(epid));
        ep = epService.getEpById(ep);
        epVO.setEp(ep);
        // depart對(duì)象
        Depart depart = new Depart();
        depart.setDeptID(ep.getDeptid());
        depart.setPlateNumber(ep.getName());
        depart.setCreateBy(userid);
        depart.setJudgeType(Integer.parseInt("0"));
        String str[] = ep.getInfo().split(";");
        String s1 = "";
        for (int i = 0; i < str.length; i++) {
            s1 = str[0];
        }

        if ("".equals(s1) || null == s1) {
            depart.setRoute("暫無(wú)路線");
        } else {
            depart.setRoute(s1);
        }
        epVO.setDepart(depart);
        // dept對(duì)象
        Dept dept = new Dept();
        dept = deptService.getDeptById(ep.getDeptid());
        epVO.setDept(dept);

}

public String save() {

        Long deptid = epVO.getDept().getDeptid();
        try {
            Depart depart = epVO.getDepart();
            depart.setDeptID(deptid);

departService.insertDepart(depart);
super.printMsg(this.getRequest(), "保存成功!");

            cleanObject();
        } catch (Exception e) {
            super.printErrors(this.getRequest(), e, className);
            return RETURN_ERROR;
        }

return list();
}

jap頁(yè)面

復(fù)制代碼代碼如下:
