BeanList延迟播放框架2.0+java

Question

我创建了两个Entity:User和Post

一个用户可以有很多帖子，所以我为User添加@OnetoMany，为Post 添加@ManytoOne

USER.JAVA--

@Entity
public class Users extends Model{
    @Id
    public Long id;
    @Constraints.Required
    @NotNull
    public String username;
    @Constraints.Required
    @NotNull
    @Constraints.Email
    public String email;
    @Constraints.Required
    @Constraints.MinLength(6)
    @NotNull
    public String password;

    @OneToMany(cascade = CascadeType.ALL, mappedBy = "user")
    public List<Post> post;
    public Users(){}
    public Users(String username,String email,String password){
        this.username=username;
        this.email=email;
        this.password=password;
        this.post=new ArrayList<Post>();
    }
}

和POST.JAVA---

    @Entity
    public class Post extends Model{
        @Id
        public Long id;
        @ManyToOne
        @JoinColumn(name = "user_id")
        public Users user;
        public String title;
        public String article;
}

当我搜索用户的信息并将其显示为：

@(users : List[Users])
@for(user <- users){
    @user.post</br>
    @user.username</br>
    @user.password</br>
    @user.email</a>
}

出现"BeanList deferred"。（不是错误，不是异常，只是一个String）

结果：

BeanList deferred  // like this

对我来说，任何帮助、任何理想或某种方式都可以将两个实体联系起来？

Answer 1

即，您需要执行以下操作：

@(users : List[Users])
@for(user <- users){
    for(post <- user.post) {
        @post.article<br/>
    }
    @user.post</br>
    @user.username</br>
    @user.password</br>
    @user.email</a>
}
