The Java Persistence API (JPA) is an enterprise-class standard for accessing Java relational data. JPA provides support for mapping Java objects to database diagrams, including a simple API design and query language expression, which is expressed to retrieve results from database mappings, and to change receipts for this result. JPA improves productivity for deve

CasThis instruction full name compare and swap is the comparison substitution instruction, which is newly added to the modern processor instruction.Guideline: Based on optimistic locking mechanism. Compares the value of a variable in memory value and the current value of the variable (old value). If it is equal, the variable is considered unchanged and the new value is used instead of the old value, otherwise the substitution fails.UnsafeIn a multithreaded environment of

This paper mainly introduces a design pattern of database-related classes. It also introduces the concrete implementation in the Java EE Framework and some considerations in the transaction processing. Introduction of Design pattern When developing a Java EE application, it is often necessary to find the various information involved in the

essentially a HashMap object that exists in the application code. Whenever a new object is added to the cache, it is saved in your app's memory. When you save a small amount of data. There is no problem with this strategy, but it is problematic to cache more than GB of data. Memcachedserver's designers use a distributed architecture that is easy to extend, so. can use memcached to do massive data cache.The memcached architecture consists of two parts

as a software integrated circuit element, which has the following characteristics: · Software IC does not have the natural polymerization of hardware IC, which is free of size and easy to expand. · Establishing an intelligent interoperability mechanism and language independence between institutions by setting up a unified binary standard; · External access to components only through the interface; · Multi-side, that is, the semantic level of component expression is high, can be connected fr

a template, Container1 is a real basin created from this template, which runs on our tomcat. So we can create a lot of container with the same image. Three. Deploy our applications on Tomcat Next we are going to deploy our application, the idea is to enter into the container1 inside, at this time can think of Container1 as a new machine, we only need to go to Tomcat WebApp lost war, and then restart on the line. 1. Go inside the container Docker exec
