当字段存在时，为什么在“字段列表”中会出现“未知列” travelplan0_.user_id”？

我已经检查了数据库中的列名，并且一切似乎正确。我不知道我得到的“字段列表”中未知列“ travelplan0_.user_id”的原因。我相信我也已经仔细检查了注释。

堆栈跟踪：

dpkg-reconfigure ca-certificates

下面是Users实体：

    <?php 

error_reporting(0);
$array=array(['code'=>'aaa','name'=>'a','qty'=>20,'price'=>12.00],
['code'=>'bbb','name'=>'b','qty'=>20,'price'=>12.00],
['code'=>'ccc','name'=>'c','qty'=>20,'price'=>12.00],
['code'=>'aaa','name'=>'a','qty'=>20,'price'=>12.00],
['code'=>'ddd','name'=>'d','qty'=>20,'price'=>12.00],
['code'=>'ccc','name'=>'c','qty'=>5,'price'=>8.00],
['code'=>'bbb','name'=>'b','qty'=>15,'price'=>10.00],
['code'=>'ggg','name'=>'g','qty'=>20,'price'=>12.00]);


foreach($array as $item) {
        $newArray[$item['code']]['code'] = $item['code'];
        $newArray[$item['code']]['name'] = $item['name'];
        $newArray[$item['code']]['qty'] += $item['qty'];
        $newArray[$item['code']]['price'] +=$item['price'];
}
$newArray=array_values($newArray);

print_r($newArray);

?>

下面是travelPlans实体：

使用referencedColumnName并定位id表中的UserDetails之类的对象字段 并使用name="user_id"在表中将其命名。

    @JsonBackReference
    @ManyToOne(cascade= {CascadeType.DETACH, CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REFRESH})
    @JoinColumn(name="user_id", referencedColumnName="id")
    private UserDetails userDetails;
