如何在Apache Sling中设置Servlet初始化参数？

import org.apache.felix.scr.annotations.Properties;
import org.apache.felix.scr.annotations.Property;
import org.apache.felix.scr.annotations.sling.SlingServlet;

@SlingServlet(
    paths = { "/path/to/servlet" },
    methods = { "GET" },
    metatype = true
)
@Properties({
    @Property(name = "param1", value = "value1"),
    @Property(name = "param2", value = "value2")
})
public class MyServlet extends SlingSafeMethodsServlet {
    // Servlet implementation
}

String param1Value = getServletConfig().getInitParameter("param1");
String param2Value = getServletConfig().getInitParameter("param2");
