In this article, the editor gives you a detailed introduction of "what is the architecture for large-scale web Internet projects". The content is detailed, the steps are clear, and the details are handled properly. I hope that this article "what is the architecture for large-scale web Internet projects" can help you solve your doubts.

Brief introduction of platform

Jeesz is a distributed framework that provides project modularization, service-oriented, hot-swappable ideas, and a rapid development platform for Java EE with high encapsulation security.

Jeesz itself integrates Dubbo service management and control, Zookeeper registry, Redis distributed cache technology, FastDFS distributed file system, ActiveMQ asynchronous message middleware, Nginx load balancing and other distributed technologies.

Use Maven for project management, modularize the project, and improve the ease of development and expansibility of the project.

Spring Framework is used as the core container, Spring MVC as the model view controller, MyBatis as the data access layer, Apache Shiro as the authorization layer, Ehcahe for caching common data, Activit as the workflow engine and so on.

The front end integrates Bootstrap4 metronic framework, UI responsive, flat layout, suitable for all PC, Pad, Anroid, ios mobile devices and so on.

Jeesz is mainly located in the Internet enterprise architecture, and has built in the basic functions of the enterprise information system and efficient code generation tools, including: system authority components, data permissions components, data dictionary components, core tool components, view operation components, workflow components, code generation and so on. Adopt hierarchical design, double authentication, submit data security coding, password encryption, access verification, data authority verification.

Jeesz currently includes the following module projects, background system management system, RestFul independent service system, Scheduler timing scheduling system, content management (CMS) system, online office (OA) system, my to-do (Task service), my collection (Bookmark service).

Background management system includes enterprise organizational structure (user management, organization management, regional management), menu management, role rights management, dictionary management and other functions.

RestFul provides standard Rest service API independently. You can quickly implement your own business and provide the services you need.

Quartz timing scheduling system can dynamically configure your task rules, etc.

Content management (CMS) system, including content management, column management, site management, public messages, document management, front-end website display and other functions

Online office (OA) system, mainly provides simple process examples.

Jeesz provides common tools for encapsulation, including logging tools, caching tools, server-side verification, data dictionaries, current organizational data (users, institutions, regions) and other common gadgets. In addition, it also provides a powerful online code generation tool, which provides simple single table, one-to-many, tree structure function generation, if the appearance requirements are not very high, the generated function can be used. The use of the Jeesz basic framework can improve the efficiency of rapid development.

Built-in features (only some of them are listed)

1. User management: the user is the system operator, this function mainly completes the system user configuration.

two。 Organization management: configure the system organization (company, department, group), show the tree structure, and adjust the superiors and subordinates at will.

3. Regional management: systematic urban regional model, such as the maintenance of countries, provinces and cities, prefectures and counties.

4. Menu management: configure system menus, operation permissions, button permission identification, etc.

5. Role management: role menu permissions are assigned and roles are set to divide data scope permissions according to the organization.

6. Dictionary management: maintain some fixed data that are often used in the system, such as whether, male or female, category, level, etc.

7. Operation log: system normal operation log record and query; system exception information log record and query.

8. Connection pool monitoring: monitor the current system database connection pool status, you can analyze SQL to find out the system performance bottleneck.

9. Workflow engine: to achieve business work order flow, online process designer.

Development tools

1.Eclipse IDE: adopt Maven project management, modularization.

two。 Code generation: simple configuration through the interface, automatically generate the corresponding code, including three generation methods (addition, deletion, modification and query): single table, one-to-many, tree structure. If the generated code does not need to pay attention to beauty, it can be used after generation.
