Collection Annotation MappingsA set-relational mapping can be thought of as a simplification of a one-to-many relationship mapping, and in an e-commerce system, the products sold may have more than one display image, and if we use a one-to-many to build an association map, we need to create an entity class images, There may be attributes: Images in the server's access path URL and picture of the product ProductID. But if we use a set-relational mapping, you don't need to create a new entity clas

1. Background of the problem Personally prefer spring data JPA, this time the problem is to use the list type as a field in the entity class, JPA also provides a way to operate, that is, using @elementcollection annotations, the online knowledge of JPA is fragmented, After all, it's not as easy to use as MyBatis. To get to the bottom, take a look at the fields in my entity class: @ElementCollection(fetch =

ReadLine (); // pause the Console; otherwise, the Console will be suspended.}Catch (WebException webEx ){Console. WriteLine (webEx. Message.

nodelist with ChildNodes, But when we manipulate the DOM, we tend not to manipulate node (I just want to manipulate element elements), so how do I get elementlist? The getelementsbyxxx that we often use returns a elementlist, except that its real name is ElementCollection . Just as NodeList is a set of node, ElementCollection is also a collection of element. But the special note: NodeList and elementcollc

There have been a few previous problems with using JPA to map members in entity, and some annotations are easy to confuse, so keep this in mind. 1. Mapping of Map The key and value of this map are both string types, or other underlying types, and can be mapped using the following method: @ElementCollection @CollectionTable (name= "table_name") @MapKeyColumn (name= "Propkey") @Column (name= "PropValue") private map 2. Mapping of Map Key is the un

Originally, we were worried that the collapse of ejb2. *'s enity beans may not make JavaEE once again leads the persistence layer standards. One important factor for success is the unambiguous support of gaving King and the JBoss community. Jpa2.0The goal is to make persistent efforts on the basis of this success to fill more

When did the problem arise?When an entity object contains more than one non-lazy fetch policy, such as @onetomany, @ManyToMany, or @elementcollection, the fetch policy is (fetch = Fetchtype.eager)Why the problem occurred:When (fetch = Fetchtype.eager) is redundant, the persistent framework grabs one side of the object, while the objects of the multi-party are loaded into the container, and multiple parties may be associated with other objects, Hiberna
