Hibernate - 如何通过Hibernate将java.net.URL存储到数据库中

Question

I have a field URL countryURL; in a Country class. I want to store its data into a COUNTRY table in a database through Hibernate.

Which Hibernate type I should use in the hibernate mapping file

<property column="COUNTRY_URL" name="countryURL" type="..."/>

It is not excepting string and text type.

Answer 1

You could write your own user type, but it might be easier to perform the conversion String <-> Url in property getters and setters:

private void setRawUrl(String s) {
    this.url = new Url(s);
}

private String getRawUrl() {
    return url.toString();
}

and map the property rawUrl with type string .

Answer 2

You can create a org.hibernate.UserType for URL which maps to a varchar column. See Custom value types in the reference documentation.

Answer 3

似乎现在有一些时候由Hibernate自己提供的专用基本值类型： org.hibernate.type.UrlType

Answer 4

I'd store it as String . No need to make your life harder by implementing a custom type. That is, change URL to String in Country .

Answer 5

没有..存储为字符串做转换我们的自我是错误的OOAD方法..一旦它是一个字符串用户总是可以给任何字符串，这可能不是URL ..更好地使用自定义T
