Problem: I cannot access static resources like images, js or css files located under default resources folder of a spring boot project. I am using spring boot version (2.4.9). Now, after doing a lot of research I came up with a solution which I found on spring doc website, which is, use the following piece of code:

.requestMatchers(PathRequest.toStaticResources().atCommonLocations()).permitAll()

Now the funny thing is, after using this piece of code I am still not able to access any file or folder under the resources folder, but I can access a folder named images (I made it) under resources folder. Any solutions or helpful tip ?

The Directory structure of my project:

CodePudding user response：

You have quite a few directories under /static that are not matched by PathRequest.toStaticResources().atCommonLocations(). The following locations are matched: /static/css/**, /static/js/**, /static/images/**, /static/webjars/**, /static/favicon.*, and /static/*/icon-*. This is why your images are accessible. You will need to add antMatchers for your custom locations with permitAll() (e.g. antMatchers("/build/**", "/delete-popup/**", ...).permitAll().
