Configuring AutoMapper Mapping RulesAutoMapper is based on conventions, so before the utility map, we need to configure the mapping rules first.public class source{Public int somevalue {get; set;} public string Anothervalue {get; set;}} public class destination{Public int somevalue {get; set;}}In the above code, we have defined two classes, and we need to map the object of the source class to the o

2017-05-20The party returned as always to see the badminton game, and then think of a few days ago and friends to discuss the problem of the reverse mapping, or a brief summary under, lest forget again later! But when I add time ... This is a little awkward ... 520 is still writing a technical blog ...Gossip not much said, before a problem is to be based on the physical page frame number to get mapped virtual address, a time do not know how to start,

On the "SSH Advanced path" hibernate mapping-a one-to-many correlation mapping (vii), we present a pair of multi-correlation mappings, which is the basis of many-to-many association mappings.Many-to-many mappings are the most common mapping in real life and the easiest to understand. Talk less and start straight.Mapping principleWhether a one-way or two-way assoc

Servlet and filter are common techniques in the development of the Java EE, easy to use and easy to configure. Url-pattern in servlet and filter There are some articles in it that summarize something to avoid problems and wasting time.One, the servlet container-to-url matching process:When a request is sent to the servlet container, the container first subtracts the requested URL from the path of the current application context as a mapped URL for the servlet, for example, I am visiting http://l

, and if no other annotations are annotated, the properties and methods of the class are automatically mapped to the default tables and fields in the database. Such as:@Entitypublic class Contacteo Implement serializable{Public Contacteo () {}Private Integer ID;private String name;Getter and Setter methods slightly}The default database table name for the entity is: Contacteo, field: int id; varchar name;mapping tables and fields:# @Table Note To defin

Object/Relation Mapping Object-relational database ing What is Orm? Object-Role Modeling (ORM) provides a conceptual and easy-to-understand Method for modeling data. The ORM methodology is based on three core principles: Simple: data is modeled in the most basic form. Communication: the database structure is documented in a language that anyone can understand. Accuracy: Create a correctly standardized structure based on the data model. Typically, mod

A: basic mapping: A data table corresponding to an entity class, called this mapping as the basic mappingTwo : relational mapping: It is the mapping that deals with the relationship between n related objects and n related tables on the basis of basic mappings. Mainly divided into the following types: One-Way A

Following the previous blogOne-to-many association mappings (unidirectional)The above we introduced a lot of one, we turn to see a pair of more than one? So do you want to use a different mapping? What's the difference? The one-to-many and multi-pair mapping principles are consistent and the storage is the same. That is, the table of the generated database is the same. The difference between them is that th

); }}Example:What's the difference between Hashset,linkedhashset and TreeSet?HashSet is implemented using a hash table, and the elements are unordered. Add, delete operation time complexity is O (1). TreeSet internal structure is a tree structure (red black tree), elements are ordered, add, delete operation time complexity is O (log (n)), and provides the first (), Last (), HeadSet (), Tailset () and other methods to handle an ordered set. Linkedhashset is between HashSet and TreeSet, the interi

The previous article discusses a one-to-many mapping in detail, and there are a lot of problems with unidirectional mappings in a pair of mappings, so it is not recommended to use a two-way association to optimize the relationship if one-to-many mappings are to be considered, which is essentially using one, one-way many-to-manyStill in accordance with the previous article format to discuss, first of all, the relationship between the object, a one-way

done on the proxy server. To do this, you can use Windows Server's port mapping feature, in addition to WinRoute Pro, as well as a variety of enterprise-class firewalls. For our ordinary users, I am afraid it is most convenient to use Windows Server. Let's start by introducing Nat,nat (Network address translation) is a way to map an IP address domain to another IP address domain technology, thereby providing a transparent route for the terminal hos

The last posting hibernate from the beginning to the Master (d) Basic mapping we've explained basic mappings and related concepts, and then we'll talk about a slightly more complex mapping--relational mapping. Relational Mapping classification Relationship mapping is the

Are you O/R Mapping? In today's software development, the phrase "O/R Mapping" is increasingly mentioned. What is o/R Mapping? In short, object/Relation Mapping maps objects to links. This name and concept come out there? Why do we need o/R Mapping during development? First,

Analysis on the model of data object mapping in PHP design mode and its design pattern PHP in the design pattern has a lot of different patterns, here we introduce a less common data mapping mode, I hope the article can help you. The data mapping pattern allows you to better organize your applications to interact with the database. The data

I am MacOS, can not provide Docker running environment, so need to use boot2docker, the problem is here, because Boot2docker is actually using vbox virtual machine, so actually external if want to access to the container, need two layers of map, can access to. Docker network structure diagram on MacOS The order from inside to outside is: container->boot2docker (virtual machine), physical machine If you are only using your own development, it is sufficient to map the port of the container to the

The nature of relevance mapping: * Mapping an association relationship to a database, the so-called association relationship is one or more references in memory of the object model If this property is omitted, the default foreign key is the same as the entity's property Example of the definition of * 1, User's Pojo class: 1public class User { 2 3　　private int id; 4 5　　private String name; 6 7　　pri
