Hibernate One to Many渴望不吸引所有数据

Question

我正在对hibernate中的一对多关系做一个急切的负担.父项目被正确拉回,但他们只在子列表中收到一个项目.其中一个父母应该有两个.我运行查询Eclipse spits out,它会得到正确的结果.问题是为什么当一个项目应该有两个时,只有一个项目进入每个列表？

 @OneToMany(mappedBy="badge", fetch=FetchType.EAGER)
     public List<BadgeLevel> getBadgeLevels() {
        return this.badgelevels;
     }

Answer 1

为了得到我需要的东西,页面大小已经关闭.因此增加显示所有外连接都通过,但它们没有正确构造.所以我添加了@Fetch注释来解决这个问题.

     @OneToMany(mappedBy="badge", fetch=FetchType.EAGER)
     @Fetch(value=FetchMode.SELECT)
     public List<BadgeLevel> getBadgeLevels() {
        return this.badgelevels;
     }
