Accessing Static Resources with a Global Front Controller Servlet Mapped on /*
When using a global front controller servlet such as the Spring MVC DispatcherServlet mapped on /*, accessing static resources like CSS, JavaScript, and images can become an issue. This mapping essentially intercepts all incoming requests, potentially preventing access to resources stored outside the controller scope.
To resolve this, consider mapping the controller servlet on a more specific url-pattern, for instance, /pages/*. This will allow the controller to handle requests for specific pages while leaving other paths open for static resource access.
Secondly, place the static content in a dedicated folder, such as /static. This separation will facilitate resource management and prevent conflicts with the controller's content.
Finally, create a Filter listening on /* that handles both static and dynamic requests transparently. In the filter's doFilter() method, examine the request URI to determine if it belongs to a static resource.
If it does (e.g., starts with "/static"), forward the request to the default servlet for processing. Otherwise, if the request belongs to the controller's scope (i.e., starts with "/pages"), forward it to the appropriate page-handling dispatcher.
This approach allows for seamless access to both static and dynamic resources while preserving the intended functionality of the global front controller servlet.
The above is the detailed content of How to Access Static Resources When Using a Global Front Controller Servlet Mapped on /*?. For more information, please follow other related articles on the PHP Chinese website!

The class loader ensures the consistency and compatibility of Java programs on different platforms through unified class file format, dynamic loading, parent delegation model and platform-independent bytecode, and achieves platform independence.

The code generated by the Java compiler is platform-independent, but the code that is ultimately executed is platform-specific. 1. Java source code is compiled into platform-independent bytecode. 2. The JVM converts bytecode into machine code for a specific platform, ensuring cross-platform operation but performance may be different.

Multithreading is important in modern programming because it can improve program responsiveness and resource utilization and handle complex concurrent tasks. JVM ensures the consistency and efficiency of multithreads on different operating systems through thread mapping, scheduling mechanism and synchronization lock mechanism.

Java's platform independence means that the code written can run on any platform with JVM installed without modification. 1) Java source code is compiled into bytecode, 2) Bytecode is interpreted and executed by the JVM, 3) The JVM provides memory management and garbage collection functions to ensure that the program runs on different operating systems.

Cloud computing significantly improves Java's platform independence. 1) Java code is compiled into bytecode and executed by the JVM on different operating systems to ensure cross-platform operation. 2) Use Docker and Kubernetes to deploy Java applications to improve portability and scalability.

Containerization technologies such as Docker enhance rather than replace Java's platform independence. 1) Ensure consistency across environments, 2) Manage dependencies, including specific JVM versions, 3) Simplify the deployment process to make Java applications more adaptable and manageable.
