jpa 中 

package com.htsc.thfx.framework.entity.user;

@Entity
public class UserInfo implements Serializable {

    @Id
    @Column(length = 50)
    private String username;//用戶名



    @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, orphanRemoval = true)
    @JoinColumn(name = "username", foreignKey = @ForeignKey(name = "none", value = ConstraintMode.NO_CONSTRAINT))
    private Set<UserAuthority> authorities = new HashSet<UserAuthority>();


}

不能只用新的set替換舊的set 需要這樣安全刪除

            List<UserAuthority> save = userAuthorityDao.save(newList);
            // jpa 替換關聯關系
            if (userInfo.getAuthorities() == null)
                userInfo.setAuthorities(new HashSet<>());
            userInfo.getAuthorities().clear();
            userInfo.getAuthorities().addAll(save);
