下面是userBean：
public class UserBean extends BaseBean {
private String userName;
private String password;
private String repassword;
private String dpt;// 新加用户时，存放用户的部门
//private List <SelectItem> department;//在编辑用户时，选择用户所在的部门
private String phone;
//private boolean[] role;
//private List groupAll;
private MonitorUser userInfo;
private String user_id;
private MonitorUser user;
//private List<MonitorGroup> allGroup;
public UserBean() {
super();
//department = new ArrayList<SelectItem>();
MonitorUserService monitorUserService = (MonitorUserService) getServiceBean("monitorUserService");
//allGroup = monitorUserService.findGroupAll();
String userid = FacesUtils.getRequestParameter("userid");
/*for(int i = 0;i<allGroup.size();i++){
MonitorGroup group = (MonitorGroup)allGroup.get(i);
this.department.add(new SelectItem(group.getGroupId(),group.getGroupName()));
}*/
if (userid != null) {
Integer id = Integer.valueOf(FacesUtils
.getRequestParameter("userid"));
userInfo = monitorUserService.findUserByUserID(id);
userName = userInfo.getUsername();
user_id = String.valueOf(userInfo.getUserid());
password = userInfo.getPassword();
repassword = password;
}
}
public String modify() {
MonitorUserService monitorUserService = (MonitorUserService) getServiceBean("monitorUserService");
if (user_id != null) {
Integer userId = Integer.valueOf(user_id);
userInfo = monitorUserService.findUserByUserID(userId);
userInfo.setUsername(userName);
userInfo.setPassword(password);
monitorUserService.updateUser(userInfo);
return "modify success";
}
return " modify false";
}
public String delete() {
MonitorUserService monitorUserService = (MonitorUserService) getServiceBean("monitorUserService");
if (user_id != null) {
Integer userId = Integer.valueOf(user_id);
user = monitorUserService.findUserByUserID(userId);
monitorUserService.deleteUser(user);
return "delete success";
}
return "delete false";
}
}
下面是userInfoBean：
public UserInfoBean(){
super();
department = new ArrayList<SelectItem>();
roles = new ArrayList<SelectItem>();
MonitorUserService monitorUserService = (MonitorUserService) getServiceBean("monitorUserService");
allGroup = monitorUserService.findGroupAll();
allRole = monitorUserService.findRoleAll();
//String userid = FacesUtils.getRequestParameter("userid");
for(int i = 0;i<allGroup.size();i++){
MonitorGroup group = (MonitorGroup)allGroup.get(i);
this.department.add(new SelectItem(group.getGroupId(),group.getGroupName()));
}
for(int i = 0;i<allRole.size();i++){
MonitorRole role = (MonitorRole)allRole.get(i);
this.roles.add(new SelectItem(role.getRoleId(),role.getRoleName()));
}
}
当页面中没有
<h:selectOneMenu id="department">
<f:selectItems value="#{userInfoBean.department}" />
</h:selectOneMenu>
和
<h:selectManyCheckbox layout="lineDirection" id="roleEdit">
<f:selectItems value="#{userInfoBean.roles}" />
</h:selectManyCheckbox>
时 修改和删除按钮都可以执行，加上后，两个按钮就失效了，还不报错
[解决办法]
如:
<h:selectOneMenu value="#{userInfoBean.depart}" >
<f:selectItems value="#{userInfoBean.department}" / >
</h:selectOneMenu >
