Java 正在从控制器更新bean值，单击按钮可多次插入

我不熟悉JSFJPARest，我想知道如何从控制器bean在bean中设置值

假设用户注册后，我想将这些值连同我在controllerbean中生成的日期一起插入数据库。现在我如何在POJO中设置这些值

我有两个控制器registerController和loginController，其中我有业务逻辑

@ManagedBean(name = "registerController")
@SessionScoped
    public String prepareCreate() {
    System.out.println("Inside create");
    current = new Register();
    System.out.println("Inside create current");
    selectedItemIndex = -1;
    return "Signup Success";
}

public String create() {
    try {
        System.out.println("I am inside create");
        getFacade().create(current);
        JsfUtil.addSuccessMessage(ResourceBundle.getBundle("/Bundle").getString("RegisterCreated"));
        return prepareCreate();
    } catch (Exception e) {
        System.out.println("I am here inside create exception");
        e.printStackTrace();
        JsfUtil.addErrorMessage(e, ResourceBundle.getBundle("/Bundle").getString("PersistenceErrorOccured"));
        return null;
    }
}

public Date generateCurrentTime()
{
    // get current system time yyyy/MMM/dd HH:mm:ss
    Calendar currentDate = Calendar.getInstance();
    SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
    String dateNow = formatter.format(currentDate.getTime());
            Date convertedDate=null;
            try
            {
            convertedDate=formatter.parse(dateNow);
            }
            catch(Exception e)
            {
                e.printStackTrace();
            }
            System.out.println("date now is:"+dateNow);
            return convertedDate;
}

类似地，loginController也包含相同的代码。 如何在pojo中为createdOn和lastUpdatedOn feilds设置convertedDate属性

我使用了@ManagedBeanProperty，但它无法设置值

@ManagedBeanProperty(value=#{registerController.getgenerateCurrentTime})
  @Column(name = "created_on")
   @Temporal(TemporalType.DATE)
   private Date createdOn;


  @ManagedBeanProperty(value=#{registerController.getgenerateCurrentTime})
  @Column(name = "created_on")
   @Temporal(TemporalType.DATE)
   private Date lastUpdatedOn;

请指出我的错误。我使用了@sessionscoped

正如你所看到的，我有两个表格，它们相互依赖。当用户单击register按钮时，我如何将它们插入到数据库中…我应该首先在按钮上传递控件，然后单击controller，比如setupController，然后调用register and login controller吗

谢谢：）

表单的提交是否会导致在backbean中存储字段的值（如果没有使用ajax）

在命令按钮中提供一个action，如

action=“#{setupController.create}”

将导致在将字段分配给bean后提交表单时调用该方法

create

你也可以以行动的形式提供它

参考

正如其他朋友所说，您需要调用一个操作来设置支持bean上的值……您可以创建一个由按钮操作调用的方法，在该方法中，您可以调用您的服务将数据存储在数据库中。干杯

您是否提供了的操作方法？我在问是否应该说action=“#{setupController.create}”，或者是否有其他方法来执行此操作。我正在使用value=“#{registerController.selected.contactName}”将值存储在后台bean中.既然我有两个控制器，我应该再创建一个控制器来传递控制器，在该控制器中我调用registerController和loginController的创建方法…同样对于每个用户，我要添加createdOn feild，它存储逻辑在控制器中的日期。我如何在我的back bean中更新这个值？？值仅在提交表单时存储在backbean中。不仅通过将其作为value=“#{registerController.selected.contactName}”提供或者你需要提供这意味着当一个用户注册时，你需要两个操作，首先你要调用createdon，然后再创建？我明白了…我所困惑的是如何在一次单击按钮时调用两个控制器？？

@ManagedBeanProperty(value=#{registerController.getgenerateCurrentTime})
  @Column(name = "created_on")
   @Temporal(TemporalType.DATE)
   private Date createdOn;


  @ManagedBeanProperty(value=#{registerController.getgenerateCurrentTime})
  @Column(name = "created_on")
   @Temporal(TemporalType.DATE)
   private Date lastUpdatedOn;
