The lazy and fetch settings in the relationship between hibernate will affect the SQL statement operations when querying data. The fetch settings have a higher priority than the lazy settings, the lazy attribute configured on the class label does not affect the associated object. (The version used in this example is hibernate3)
In this example, a master table is

Some people think the book is not suitable for beginners. Personally, although I do not fully agree to have some programming experience to read this book, but I must recommend to beginners. After all, this book is written for the famous 6.001, MIT's introductory programming course. This book may take a lot of effort (especially wh

What is LazyLoad technology? When there are many pages, opening a page will inevitably lead to interaction with the server with a large amount of data. Especially for high-definition images, it occupies several hundred KB of space. Lazy Load is a jQuery plug-in written in JavaScript. it delays loading images on long pages. images outside the visible area of the browser are not loaded until the user scrolls the page to their location. this is the oppos
This article provides 15 criteria for evaluating software developers, which can help programmers become excellent programmers from a good programmer!
How to assess a software developer? This is a strange problem. Now there are a lot of theories and forms to do this, and the human resources department also tries to help you manage and reflect on your own behavior. However, how can you be a great software developer? How can you develop your career today

Enterprise-class technology refers to the technology in the Java EE platform, which is mostly derived from the existing accumulation of standards, such as JPA to a large extent from hibernate. The application of enterprise-class technology is of great benefit to the standardization of programs.The standard class library and open source project understanding is not in order, can be cross-cuttin

Here we'll talk about Hibernate's caching mechanism. First of
One, 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 amoun
