With the increasing use of content management systems (CMS), how to regulate content and protect digital assets is a problem. For example, all branches of an organization in China have their own websites and various web applications, but the website architecture is different, and the content storage is also based on their own needs. JCR was proposed to standardize content management, while jackrabbit is an open-source project under the Apache fund, fu

Introduction to JCR and Apache Jackrabbit
JCR is an abbreviation for the content Repository for Java Technology API, translated as a Java Contents Storage specification, whose specification is defined in JSR170 and JSR283, which define the JCR version 1.0 and 2.0, respect
Apache Jackrabbit is an open source implementation of JSR-170 provided by Apache Foundation.With the growing popularity of content management applications, the need for a common, standardized API for content warehouses has been highlighted. The goal of the Content Repository for Java technology API (JSR-170) is to provide such an interface. A major advantage of JSR-170 is that it does not bind to any particular underlying architecture. For example, th
Comparing a person to a class, a person is composed of a brain, a limb, an organ, and a nested class is equivalent to one of its organs, such as a heart: it also has its own properties and behavior (blood, beating).Structure of nested classes (Nested Class):Outer classes class out { private int-age = n; N

A passage in Java programming thought:When writing a Java source code file, this file is often referred to as a compilation unit (sometimes referred to as a translation unit). Each compilation unit must have a suffix name. java, and within the compilation unit you can have a public class that has the same name as the file (including case, but not the suffix of the file. Java). Each compilation unit can have only one public
The inner classes can be static (static) and can use public, protected, and private access controls, while external classes can use only public, or default.A class that is directly defined within a member's inner class (not inside a method or inside a code block) is a member inner class that can directly use all the variables and methods of an external

When more than one class is common to many methods, the common method part can be extracted, and the required class is related to inheritance.
