我使用的解决方法是LifeCycleCallback。仍然在等待是否有更多的“原生”方法，例如@Column(type="string"， default="hello默认值")。

/**
 * @Entity @Table(name="posts") @HasLifeCycleCallbacks
 */
class Post implements Node, \Zend_Acl_Resource_Interface {

...

/**
 * @PrePersist
 */
function onPrePersist() {
    // set default date
    $this->dtPosted = date('Y-m-d H:m:s');
}

这些对我都没用。我在doctrine的网站上找到了一些文档，上面说直接设置值来设置默认值。

https://www.doctrine-project.org/projects/doctrine-orm/en/2.6/reference/faq.html#how-can-i-add-default-values-to-a-column

private $default = 0;

这将插入我想要的值。

你也可以使用xml:

<field name="acmeOne" type="string" column="acmeOne" length="36">
    <options>
        <option name="comment">Your SQL field comment goes here.</option>
        <option name="default">Default Value</option>
    </options>
</field>

下面是如何在PHP 8中使用属性来做到这一点。

#[ORM\Column(type: 'boolean', nullable: false, options: ['default' => 0])]
#[Assert\NotNull()]
private bool $isFavorite = false;

我也遇到过同样的问题。我希望将数据库中的默认值(自动地)放入实体中。你猜怎么着，我做到了。
