What is deferred loading? Lazy loading is when an application wants to get an object from the database (without setting the Lazy property value to false), hibernate simply gets the OID of the qualifying object from the database and generates the proxy object without loading the object The corresponding value is loaded when the property of the object is Accessed. The simple answer is to reduce the amount of

Lazy Load Detailed Lazy loading for Hibernate is one of the most common features, the following is a detailed understanding of the principle of lazy loading and considerations lazy Load principle of load () method In hibernate, there are two query methods, respectively, get () and load (), and the difference is that l

What is lazy loading? What's his role?Deferred loading, also known as lazy loading, is a mechanism that hibernate provides to improve program execution efficiency, which is only created when data is actually used for that object.Hibernate is mainly implemented by proxy mechanism to implement lazy loading. It's specific process: hibernate when a database acquires

Lazy Seminar launched in late August 2008, the last month of Friday held, Taobao ued front-end engineers exchange and sharing of the event, but also the predecessor of D2. Lazy, the first "lazy" is the hope that the front end of one months of hard work can put down their hands, to lazy eat snacks,

Lazy loading means that the program delays accessing the database. This ensures that sometimes it is unnecessary to access the database because it is time-consuming to access the database once. I. load Method lazy loading First look at the following code segment 1 public class UserManager { 2 3 public static void main(String[] args) { 4 Users user = new Users(); 5 user.setBirthday(new

can apply quite a few optimizations for ThisProcess.As if to say, do not use the primary key (by primary key) to query, because the primary key area query will bypass the first level and level two cache.So we recommend using get and load to queryThe following test is wrong, to see the correct conclusion of the coffin, please jump to:Ultimate test: --------------------------------------------To implement lazy loading:How to implement

In the hibernate framework, when the amount of data we want to access is too large, obviously the cache is not appropriate, because the memory capacity is limited, in order to reduce the concurrency and reduce the consumption of system resources, hibernate with lazy loading mechanism to compensate for this flaw, But it's just a fix, not a lazy load. Overall performance is improved.What we call

Lazy loading requires that the domain object cannot be final, because Hibernate needs to generate a class that inherits from the domain object to implement lazy loading. There are three main types of lazy loading:1. Lazy Loading of objects2. Lazy loading of associated collec

I. Concept of deferred loadingWhen hibernate loads an object from the database, it does not load the associated object, but only the proxy object, obtaining a proxy object that uses the load in the session (without changing the lazy property to false). So in the above scenarios it is deferred loading.Two. Understanding the concept of immediate loadingWhen hibernate loads an object from the database, it loads the associated object, generates the actual

Personally, this book has so far been a programming book that has affected my intoxication.The classic books of code, refactoring, and design patterns teach you efficient work habits and trading details. Other such books as "The Human episode", "Computer Programming Psychology" and "The Human Moon Myth" go deep into the psychological aspect of software development. Other books deal with the algorithm. These books all have their own place to belong. However, the construction and interpretation o

I'm sure you have doubts about the title, but that's exactly what the title is for Android developers. As far as I know, Android programmers are reluctant to write Findviewbyid (), click event Monitoring and other high repetition rate code. So how can we shorten the time to write business logic code and avoid writing repetitive code? So let's be an Android programmer who can be lazy and efficient. Want to k

I heard that married to marry programmers, money more words less die early. This is mostly the programmer's own black. Programmers have a very special sense of humor a group, good at self-deprecating, the courage to black, strong tolerance, a lot of things Wucken, not to be able not to endure the crown an anger. However, it is such a nice person, there are some things that can not stand.Changes in demandWhy is the "demand change" ranked first?Because someone said: Kill a
