问题 I have class Money which is an @Embeddable @Embeddable public class Money implements Serializable, Comparable<Money> { @Column(name = "amount", precision = 15, scale = 2) private BigDecimal amount; } When I useit multiple time inside entity, everything works fine. For example @Entity public class SomeEntity implements Serializable { @Embedded @AttributeOverride(name = "amount", column = @Column(name = "entry")) private Money entryValue; @Embedded @AttributeOverride(name = "amount", column =

JPA / Hibernate OneToMany Mapping, using a composite PrimaryKey

问题 I'm currently struggling with the right mapping annotations for a scenario using a composite Primary Key Class. First, what I am trying to achieve in words: I have 2 classes: group and FieldAccessRule. A Group can have many FieldAccessRules, while a FieldAccessRule only has ONE Group assigned. Modling this is not a problem so far (simplified): public class Group{ ... @OneToMany(mappedBy = "group") private Set<FieldAccessRule> fieldAccessRules; ... } and for the FieldAccessRule: public class

Embeddable widgets using jQuery and ASP.NET MVC

I need some advice for the best approach to use in developing embeddable widgets that my site users could use to show our content on their site. Let's say we have some content which uses a jQuery plugin to be rendered, and we want to give our customers an easy way to embed it in their websites. One option could be of using an IFrame, but as we know this is quite invasive and has some problems. I'd like to know your opinion on that, too. Another approach could be giving a code like this, to show item #23: <DIV id="mysitewidget23"><script src="http://example.com/scripts/wdg.js?id=23" /></DIV>

Can I make an embedded Hibernate entity non-nullable?

由 ╄→гoц情女王★ 提交于 2019-11-27 20:02:58
What I want: @Embedded(nullable = false) private Direito direito; However, as you know there's no such attribute to @Embeddable. Is there a correct way to do this? I don't want workarounds. Embeddable components (or composite elements, whatever you want to call them) usually contain more than one property and thus are mapped to more than one column. The entire component being null can therefore be treated in different ways; J2EE spec does not dictate one way or another. Hibernate considers component to be NULL if all its properties are NULL (and vice versa). You can therefore declare one (any)
