Suddenly think of their own more than six months ago in a Web site to do some of the Java basic questions, was holding a full of confidence to go, the results found that a lot of basic knowledge is not understood or not fully understood. Some people learn programming from the application development began, which is very good, but there are always some small knowledge, we have not noticed, does not accumulate bujikuibu not even thousands of miles, I have encountered some of the listed out, I hope
I have heard that hibernate has been around for a long time, but it has not been close to it until recently. I saw a training PPT in xiangji a long time ago. It said that hibernate is applied to the persistent layer, and Hibernate and persistence seem to be in a pair. So what is hibernate used for? What are its advanta
Delayed loading and caching in Hibernate, and delayed loading in hibernateWhat is delayed loading? Delayed loading means that when an application wants to obtain an object from the database (when the value of the lazy attribute is not set to false), Hibernate only obtains the OId of the object that meets the condition from the database to generate a proxy object, the object is not loaded. The correspondin
SSH framework-transition of three statuses of hibernate, ssh-hibernate1. amazing things When I used the findAll () method to investigate a List object, I performed some operations on the list object without calling the update or saveOrUpdate method, the changed data is magically saved to the database. Finally, the simple and crude solution is to copy the List found from the data, operate it, and return the result. The data is normal, and the database
