lazy programmer

We often encounter lazy loading problems in the development, in the entity mapping, many-to-one and many-to-many, many of the same property by default is Lazy= "true" (that is, the default is lazy loading),such as: Delay loading performance in: For example: We want to query the department data ID 2, but there are many user data of the department foreign key is ID

No session problem, that is, lazy loadingThe problem with lazy loading is that when we finish invoking a method in the action, we find that the session opened in DAO is closed when we want to display the information we want on the JSP page.For example, the first arrow indicates that we return through the front page action,action will call DAO through the service layer to access the database, when the value

Fetch and lazy configuration queries for data lazy parameter values commonly have false and default Lazy = True in true,hibernate3 mapping files, fetch specifies how the associated object is fetched, parameter values are typically select and join, and default is Sele CT, select method first query the main object, and then according to the correlation foreign key,

[Updated, 2008-11-20 --> see end of post] One of the questions that is asked again and again in the NHibernate user mailing list is the question about whether NHibernate supports lazy-loading of properties. The answer isNO-At least for the time being. Why is this question reasonable? Well, often we have entities in our domain that contain fields with large amount of data. Some samples are A large binary object (BLOB, e.g. an image, a Word document,

There are about two ways to implement a single example: lazy and a hungry man. lazy: Hence the name of righteousness, not to the last resort to instantiate the class, that is, the first time to use the class instance will be instantiated, so the top of the classic method is classified as lazy implementation; a hungry man: you must be hungry. So it is instanti

/** Single case mode:* A hungry man: Create an object as soon as the class is loaded* Lazy Type: When used, to create objects* Interview question: What is the idea of singleton mode? Write a code representation (we'd better write a lazy singleton pattern to the interviewer, this is the answer he wants)* Development use: Bad Han style (is not a problem of the singleton mode)* Slip-on during interview (Single

What is lazyload technology? When the picture is more on the page, opening a page will inevitably cause a large amount of data interaction with the server. Especially for High-definition pictures, accounting for hundreds of k space. Lazy Load is a jQuery plug-in written in JavaScript. It can delay loading a picture in a long page. Pictures outside the viewable area of the browser are not loaded until the user scrolls the page to their location. Thi
