getService metodu
Elimizde şöyle bir kod olsunŞu satırı dahil ederiz.
addServlet metodu
Şöyle yaparız.
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-core</artifactId>
<version>${tomcat.version}</version>
</dependency>
Tomcat SınıfıaddServlet metodu
Şöyle yaparız.
Tomcat tomcat = new Tomcat();
tomcat.setPort(8082);
tomcat.addContext("/", "/web");
Context ctx = tomcat.addContext("/", new File(".").getAbsolutePath());
Tomcat.addServlet(ctx, "Embedded", new HttpServlet() {
@Override
protected void service(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
Writer w = resp.getWriter();
w.write("Embedded Tomcat servlet.\n");
w.flush();
w.close();
}
});
ctx.addServletMappingDecoded("/*", "Embedded");
tomcat.start();
tomcat.getServer().await();
setBaseDir metodu
Örnek
Şöyle yaparız
import org.apache.catalina.Wrapper;
import org.apache.catalina.startup.Tomcat;
public class TomcatEmbedded {
public static void main(String... args) throws Exception {
File baseFolder = new File(System.getProperty("user.dir"));
File appsFolder = new File(baseFolder, "apps");
Tomcat tomcat = new Tomcat();
tomcat.setBaseDir(baseFolder.getAbsolutePath());
tomcat.setPort(8080);
tomcat.getHost().setAppBase(appsFolder.getAbsolutePath());
// Call the connector to create the default connector.
tomcat.getConnector();
tomcat.addWebapp("", ".");
Wrapper wrapper = tomcat.addServlet(EMPTY, "hello", new HelloServlet());
wrapper.setLoadOnStartup(1);
wrapper.addMapping("/*");
tomcat.start();
tomcat.getServer().await();
}
private static class HelloServlet extends HttpServlet {
...
}
public class CustomLoggerValve extends ValveBase {
private static final Logger logger = LoggerFactory.getLogger(CustomLoggerValve.class);
@Override
public void invoke(Request request, Response response)
throws IOException, ServletException {
try {
MDC.put("requestId", UUID.randomUUID().toString());
logger.info("Received request");
getNext().invoke(request, response);
} finally {
MDC.remove("requestId");
}
}
}
Şöyle yaparızTomcat tomcat = // ... your tomcat setup
tomcat.getService().getContainer().getPipeline().addValve(new CustomLoggerValve());
