Today, I will talk to you about how to solve cross-domain problems through yue-library in SpringBoot. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

Cross-domain description

Under the separation of front and rear, cross-domain has become a clich é topic, but many small partners still often face this problem, and the solutions are varied. Here is a simple and direct back-end solution.

Initialized. ") ; return new CorsFilter (source);}} Cross-domain solution based on yue-library

The above code is extracted from yue-library, so yue-library-based projects have solved cross-domain problems by default. Yue-library is an enhanced library of SpringBoot. Cross-domain can be solved by introducing project dependency.

Maven project, add the following code to the pom.xml file, and replace ${version} with the corresponding version number:

Ai.ylyue yue-library-dependencies ${version}

Then introduce the required modules, such as the basic library: yue-library-base

Ai.ylyue yue-library-base...

Conclusion

Cross-domain problems are recommended to be solved by the server. There is no need to enable cross-domain security access restrictions. It can only prevent JS script injection in some browsers, but cannot achieve real security access restrictions. If you have any questions, please leave a message below.
