Spring Framework FAQ: Top Questions

DispatcherServlet is the front controller in Spring MVC that handles all incoming HTTP requests and delegates them to appropriate handlers.

📘 Core Responsibilities:

• Intercept requests using URL mapping.
• Delegate to controllers, resolve views, handle exceptions.

📥 Example (web.xml-style config):

<servlet>
  <servlet-name>dispatcher</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>

<servlet-mapping>
  <servlet-name>dispatcher</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

🏆 Expected Output:

Requests routed through DispatcherServlet to respective controller methods.

🛠️ Use Cases:
