Java JPA Eclipselink错误插入到表中

因此，首先是一些背景故事。我遇到的问题是当我创建一个用户时。之前，我曾尝试创建一个用户并分别为其分配一个角色，后来发现，通过插入SEC_user_role表，程序也在插入APP_user表，我在将重复值插入父表时出错。但是，现在通过一起创建用户和角色，我得到了以下错误：

主键应该是基元（或复合键的基元列表） pk），java.lang.Long的一个实例，其中填充了主键或 WebIntSecRole的实例

代码如下，不确定哪里出了问题，也不确定此时的最佳解决方案

Admin.java：

            //New User Creation
    WebIntUser newUser = new WebIntUser();
    newUser.setLoginId(newLoginName);
    newUser.setCreatedBy(loggedUser);
    newUser.setCreatedOn(today);
    newUser.setDbAuth(true);
    newUser.setDeleted(false);
    newUser.setDisabled(false);
    newUser.setEmail(newEmail);
    newUser.setEncrypted(true);
    newUser.setEncryptPassword(true);
    newUser.setFirstName(newFirstName);
    newUser.setLastName(newLastName);
    newUser.setUpdatedBy(loggedUser);
    newUser.setUpdatedOn(today);
    newUser.setVersion(1);
    newUser.setLdapId(1);
    //userService.createUser(newUser);

    //Set role for new user
    WebIntSecRoleUser newUserRole = new WebIntSecRoleUser();
    newUserRole.setUser(newUser);
    newUserRole.setDeleted(false);
    newUserRole.setRole(userService.selectRoleById(1));
    //newUserRole.setCreatedBy(loggedUser);
    //newUserRole.setCreatedOn(today);
    //newUserRole.setUpdatedBy(loggedUser);
    //newUserRole.setUpdatedOn(today);
    newUserRole.setVersionNumber(0);
    userService.createRole(newUserRole);

注意：有一些注释掉的代码，我正在尝试不再使用，或者在Created By和Created On etc的情况下，我多次插入都会出错。

我认为您错过了

WebIntSecRole

上的@Manytone映射。您只指定了@JoinColumn

@ManyToOne(/* desired options */)
@JoinColumn(name="ROLE_ID", nullable=false)
public WebIntSecRole getRole() {
    return role;

这是真的，尽管我仍然遇到了错误你确定吗。。userService.selectRoleById（1）。。这不会返回空值吗？是否可以显示更多异常，例如堆栈跟踪？我不知道创建人和创建时间的设置如何可能导致多个插入，所以这段代码还有更多内容。我猜问题出在你的用户服务上。选择RoleById（1）方法调用，由于异常似乎与JPA或您显示的实体无关，这就像有人试图查找WebIntSecRole，但不理解给定给它的值。我通过将WebIntSecRole的Id从Long更改为整数来实现这一点。（selectRoleById返回空值）感谢所有人为我指明了正确的方向，最微小的事情已经阻碍了我的进步。非常感谢！
