Spring Boot - @ServletComponentScan Examples

Spring Boot 

In the embedded servlet environment, this annotation enables the scanning for @WebServlet, @WebFilter and @WebListener components. Let's have a look at it's definition:

package org.springframework.boot.web.servlet;
 .....
@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Import(ServletComponentScanRegistrar.class)
public @interface ServletComponentScan {

  @AliasFor("basePackages")
  String[] value() default {};

  @AliasFor("value")
  String[] basePackages() default {};

  Class<?>[] basePackageClasses() default {};
}

value() or basePackage: specifies base package name to be scanned

basePackageClasses: specifies classes whose package(s) will be scanned

Examples

package com.logicbig.example;

import org.springframework.boot.Banner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
@ServletComponentScan
@SpringBootApplication
public class Main  {

    public static void main (String[] args) {
        SpringApplication sa = new SpringApplication(Main.class);
        sa.setLogStartupInfo(false);
        sa.setBannerMode(Banner.Mode.OFF);
        sa.run(args);
    }
}
