For many Java developers or learners, finding excellent finished website source code for learning, reference or secondary development is an effective way to improve skills and accelerate project progress. This article has selected a series of high-quality Java finished website source code and free entrance and navigation platforms for open source projects to help you easily find the resources you need and broaden your horizons.

1. GitHub: The world's largest code treasure house

1. Introduction : As the world's top code hosting platform, GitHub is the first choice for finding any type of open source project (including Java finished websites). Not only is it huge in code, it is also active in the community, rich in documentation and discussion.

2. Usage skills : Enter keywords such as "java web project", "java e-commerce", and "spring boot management system" in the search box to accurately find a large number of complete Java website projects. Using the "Topics" tags (such as `java`, `spring-boot`, `vue`) and advanced search functions (sorted by star count, update time), you can quickly filter out high-quality and popular projects.

3. Recommended reasons : There are many types of projects, from personal blogs to large enterprise-level e-commerce and backend management systems. It is the best platform for learning cutting-edge technologies and project architecture.

2. Gitee (Mai Cloud): the preferred community for domestic developers

1. Introduction : Gitee is a Chinese code hosting platform, also known as "domestic GitHub". For domestic developers, access speed is faster, and the Chinese interface and documents are also more friendly.

2. Usage skills : Gitee also has powerful search functions, and its "Open Source Project" section will recommend many excellent domestic Java projects. You can search for Chinese keywords such as "Java Blog", "Java Mall", and "Java Backend Management".

3. Recommendation reason : It brings together a large number of finished projects that meet domestic business scenarios, such as the backend management system developed based on popular frameworks such as RuoYi and JeecgBoot, which is very suitable for domestic developers to get started or learn directly.

3. SourceForge: a distribution center for old open source software

1. Introduction to the entrance : SourceForge is an open source software development and distribution platform with a long history. Although the interface is relatively old, it has accumulated a large number of mature and stable open source projects.

2. Usage skills : Through its category directory browsing, you can find many classic Java Web applications, such as content management system (CMS), forums (BBS), customer relationship management (CRM), etc.

3. Recommended reason : If you need to find some basic application source code that has been tested and has stable functions, SourceForge is a good supplementary resource library.

4. Java-Source.net: Focus on Java source code sharing

1. Introduction : This is a website that specializes in sharing Java source code. Although the scale is not as large as GitHub, the content is very focused. The website classifies the code in detail and makes it easy to find.

2. Usage tips : You can search according to categories such as "Web Applications", "Enterprise", "Desktop Applications", etc. The website provides the source code of many small and medium-sized complete projects or functional modules.

3. Recommended reason : clear positioning and focusing on the Java field, it is very helpful for finding source codes for specific functional modules or small training projects.

V. Official example projects of major technical frameworks

1. Introduction : Many mainstream Java Web frameworks, such as Spring, Play Framework, JFinal, etc., will provide complete sample projects (Sample/Demo Project).

2. Usage tips : directly access the "Guides" or "Samples" part of Spring's official website, or search for projects published by the official framework account on GitHub. These examples are authoritative material for learning framework best practices.

3. Reason for recommendation : The code quality is extremely high, following the best practices recommended by the official is the most direct and reliable way to understand and master the core usage of the framework.

Summarize

By making good use of these platforms, you can not only find a large amount of Java finished website source code as a reference, but also gain an in-depth understanding of the architectural design, coding specifications and technical selection of excellent projects. When learning and using these open source projects, it is recommended that you first read the project's README documentation to understand its technology stack and deployment methods. At the same time, be sure to pay attention to the open source license (license) of the project to ensure that your usage is in compliance with regulations. From imitation, deployment to secondary development, these finished website resources will be valuable assets on your Java technology growth path.
