Java transient keywords Use note, transient note Ah, although I am the most familiar with Java, I don't know much about the basic knowledge of Java. For example, the transient keyword has never been used before, so I don't know what it works, I found a question about this when I did the pen test today. So I took the time to sort out the use of the

The usage of transient in the source code, and the usage of the source code transient Java serialization provides a mechanism for persistence object instances. When a persistent object is stored, there may be a special object data member. We do not want to use the serialization mechanism to save it. To disable serialization on a domain of a specific object, you can add the keyword

ID value, so then? SPRINGMVC will bring your associated object back to new an empty object to this object, and this empty object is definitely not in the database, So when you save the object, you report an error in the transient state of the object that is associated with an optional value. The solution is to make a decision before hibernate save a single object. Whether the associated object is empty (note that the associated object entity configur

Access control of the transient daemonwe know that the transient daemon is made up of the Super daemon process xinetd management, due to the super-guardian process to accept TCP Wrappers access control, so the transient daemon also accepts TCP Wrappers of control management. Although TCP Wrappers access restrictions can be made to the

What kind of communication can make information symmetrical? In fact, the simplest way to let information symmetry is replication, unfortunately, even if the human brain can not be turned into a computer, so communication becomes the only way, language is the way of communication between people, the Web page is the server and the user's way of communication. Normal: elements are always displayed on the page;transient: elements need mouse hover, click

What is the difference between an object in a Free state and an object in a transient state. Answer one: There are 3 types of Hibernate objects: Transient (Transient), persistent (persistent), and off-state (Detached). Objects that are in persistent state are also known as PO (Persistence object), and instantaneous and de-tube objects are also known as VO (Value

should interact directly with the shared member variable.Recommendation: Use volatile on member variables accessed by two or more threads. You do not have to use when the variable you want to access is already in a synchronized code block, or it is a constant.Because using volatile masks the necessary code optimizations in the VM, it is less efficient, so use this keyword when necessary. java key word transient Transferred from http://horst.sun.blog.

Transient,volatile and STRICTFP keywords in Java Reprinted from: http://www.iteye.com/topic/52957 If you declare an instance variable with transient, its value does not need to be maintained when the object is stored.
