Question

我有一个小问题：我在SalesBean.java中创建了链接到我的onload函数的commandButton，并且我想在单击commandButton之后用属于登录用户的属性填充数据表，但是这种方法对我不起作用，单击之后什么都没有发生（在调试模式下，SalesBean.onload中的断点是还没到）。你知道这是怎么回事吗？为什么不执行SalesBean.onload（）？

如果我在@PostConstruct中取消注释行-在SalesBean用户中指定的属性正确显示，但是我想显示已登录用户的属性，如何实现？或者也许-如何在页面加载时执行SalesBean.onload（）？我读到有关Primeface的remoteCommand的信息，该行也在我的sales.xhtml中，但表仍然为空

这是我的SalesBean.java

package application.beans;

import application.model.views.AuctionView;
import application.service.AuctionViewService;
import application.service.UserService;
import lombok.Getter;
import lombok.Setter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;
import javax.el.MethodExpression;
import javax.faces.application.FacesMessage;
import javax.faces.bean.RequestScoped;
import javax.faces.context.FacesContext;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

@Setter
@Getter
@RequestScoped
@Component
public class SalesBean implements Serializable {

    @Autowired
    private  AuctionViewService auctionViewService;

    @Autowired
    private UserService userService;

    private String firstName = "first";
    private String lastName = "last";
    private List<AuctionView> userProperty = new ArrayList<>();

    @PostConstruct
    public void init() {
        //userProperty = auctionViewService.findByEmail("seller@seller.com");
    }

    public void onload() {
        String userName = userService.getLoggedUser();
        userProperty = auctionViewService.findByEmail(userName);
    }
}

和sales.xhtml：
