下拉列表类
public ArrayList JSselet() {
String sql = "select * from t_rkdt";
conn = db.getDBManager();
try {
ArrayList list = new ArrayList();
pstmt = conn.prepareStatement(sql);
rs = pstmt.executeQuery();
while (rs.next()) {
StoreBean bean = new StoreBean();
bean.setHzh(rs.getString("hzh"));
bean.setHzmc(rs.getString("hzmc"));
bean.setKwh(rs.getString("kwh"));
bean.setSpmc(rs.getString("spmc"));
bean.setJz(rs.getFloat("jz"));
bean.setJs(rs.getInt("js"));
bean.setZl(rs.getFloat("zl"));
list.add(bean);
}
} catch (Exception ex) {
ex.printStackTrace();
}
return (ArrayList) list;
}
Action类
public ActionForward execute(ActionMapping actionMapping,
ActionForm actionForm,
HttpServletRequest servletRequest,
HttpServletResponse servletResponse) {
StoreForm storeForm = (StoreForm) actionForm;
Chuku cks= new Chuku();
List list = cks.JSselet();
servletRequest.setAttribute("list",list);
return actionMapping.findForward("chuku");
}
