Annotation Type WebServlet

@Target(TYPE)
@Retention(RUNTIME)
@Documented
public @interface WebServlet

This annotation is used to declare the configuration of a Servlet.
If the name attribute is not defined, the fully qualified name of the class is used.

At least one URL pattern MUST be declared in either the value or urlPattern attribute of the annotation, but not both.

The value attribute is recommended for use when the URL pattern is the only attribute being set, otherwise the urlPattern attribute should be used.

The class on which this annotation is declared MUST extend HttpServlet.

E.g. @WebServlet("/path")}
public class TestServlet extends HttpServlet ... {
E.g. @WebServlet(name="TestServlet", urlPatterns={"/path", "/alt"})
public class TestServlet extends HttpServlet ... {

Since:

Servlet 3.0 (Section 8.1.1)
