Here is a quick start guide for Java Servlet Annotations:

1. @WebServlet

The @WebServlet annotation is used to define a servlet and map it to a URL pattern. It can be used in place of the traditional web.xml deployment descriptor. Here is an example:

@WebServlet(name = "MyServlet", urlPatterns = { "/hello" })
public class MyServlet extends HttpServlet {
  // ...
}

This example maps the MyServlet class to the URL pattern /hello.

2. @WebFilter

The @WebFilter annotation is used to define a filter and map it to a URL pattern. Here is an example:

@WebFilter(filterName = "MyFilter", urlPatterns = { "/*" })
public class MyFilter implements Filter {
  // ...
}

This example maps the MyFilter class to all URL patterns.

3. @WebListener

The @WebListener annotation is used to define a listener for various events in the servlet container. Here is an example:

@WebListener
public class MyServletContextListener implements ServletContextListener {
  // ...
}

This example defines a listener for the ServletContext.

4. @WebInitParam

The @WebInitParam annotation is used to define initialization parameters for a servlet or filter. Here is an example:

@WebServlet(name = "MyServlet", urlPatterns = { "/hello" }, initParams = {
  @WebInitParam(name = "foo", value = "bar")
})
public class MyServlet extends HttpServlet {
  // ...
}

This example defines an initialization parameter named "foo" with a value of "bar" for the MyServlet class.

5. @MultipartConfig

The @MultipartConfig annotation is used to configure a servlet to handle HTTP multipart requests. It can be used to specify the maximum size of a file upload or the location to store uploaded files. Here is an example:

@MultipartConfig(location = "/path/to/upload/directory", maxFileSize = 10 * 1024 * 1024, maxRequestSize = 50 * 1024 * 1024)
public class FileUploadServlet extends HttpServlet {
  // ...
}

This example configures the FileUploadServlet to handle file uploads, specifying the location to store uploaded files, as well as the maximum size of a file upload and the maximum size of the entire request.

These are some of the most commonly used Java Servlet annotations. By using these annotations, you can configure your servlets, filters, and listeners in a more concise and readable way than with the traditional web.xml deployment descriptor.
