java - Rest Api 不显示关系数据

问题描述

我正在尝试使用 spring boot 和 spring data jpa 显示数据多对一的双向映射。请看下面的实体：

TinTuc 实体

@ Entity
@ NamedQuery(name="Tintuc.findAll", query="SELECT t FROM Tintuc t")
@ JsonIgnoreProperties({"hibernatelazyinitializer", "handler"})
public class Tintuc {
//  private static final long serialVersionUID = 1L;

LoaiTinTuc 实体

NguoiDung 实体

    }

    public String getDiaChi() {
        return this.diaChi;
    }

    public void setDiaChi(String diaChi) {
        this.diaChi = diaChi;
    }

    public String getEmail() {
        return this.email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getImg() {
        return this.img;
    }

    public void setImg(String img) {
        this.img = img;
    }

    public String getMatKhau() {
        return this.matKhau;
    }

    public void setMatKhau(String matKhau) {
        this.matKhau = matKhau;
    }

    public int getQuyen() {
        return this.quyen;
    }

    public void setQuyen(int quyen) {
        this.quyen = quyen;
    }

    public int getSoDienThoai() {
        return this.soDienThoai;
    }

    public void setSoDienThoai(int soDienThoai) {
        this.soDienThoai = soDienThoai;
    }

    public String getTen() {
        return this.ten;
    }

    public void setTen(String ten) {
        this.ten = ten;
    }

    public List<Binhluan> getBinhluans() {
        return this.binhluans;
    }

    public void setBinhluans(List<Binhluan> binhluans) {
        this.binhluans = binhluans;
    }

    public Binhluan addBinhluan(Binhluan binhluan) {
        getBinhluans().add(binhluan);
        binhluan.setNguoidung(this);

        return binhluan;
    }

    public Binhluan removeBinhluan(Binhluan binhluan) {
        getBinhluans().remove(binhluan);
        binhluan.setNguoidung(null);

        return binhluan;
    }

    public List<Tintuc> getTintucs() {
        return this.tintucs;
    }

    public void setTintucs(List<Tintuc> tintucs) {
        this.tintucs = tintucs;
    }

    public Tintuc addTintuc(Tintuc tintuc) {
        getTintucs().add(tintuc);
        tintuc.setNguoidung(this);

        return tintuc;
    }

    public Tintuc removeTintuc(Tintuc tintuc) {
        getTintucs().remove(tintuc);
        tintuc.setNguoidung(null);

        return tintuc;
    }

}

休息控制器

@GetMapping
    public List<Tintuc> getAllList(){
        return tinTucService.getAllList(1);
    }

现在问题开始了，看看我的输出，它不显示来自 NguoiDung 或 LoaiTinTuc 的数据：

在此处输入图像描述

我需要输出：

{
   "idTinTuc": 1,
   "hinhAnhTinTuc":"1.jpg",
    ....
   "LoaiTinTuc":[
     {"id":1,
       "tenLoaiTinTuc":"tin hot"},
    ....
   ]
   "NguoiDung":
   [
     {id: "1", 
      ten:"name",
   ...
   ]
}

请向我建议我做错了什么。提前致谢！！
