1. Overview
Every application should require its default landing page or we can say default index or welcome page. The user will land to default index page when the user types the only domain name. Spring boot provides very easy ways to default index page.
Solution 1: index.html page inside public
create an index.html page inside resources/public/index.html
Solution 2: index.html page inside static
create an index.html page inside resources/static/index.html
Solution 3: Using controller Mapping
Create a controller with@RequestMapping("/")
which will return view name but for this requires any view configuration. Here is spring boot jsp example
package com.javadeveloperzone.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; /** * Created by Java Developer Zone on 19-07-2017. */ @Controller public class IndexController { @RequestMapping("/") public String index() { return "Spring Boot Example"; } }
2. Example:
In this example, we have createdindex.html
page inside resources/public/index.html
page.

2.3 SpringBootConfig
package com.javadeveloperzone; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.ComponentScan; /** * Created by JavaDeveloperZone on 19-07-2017. */ @SpringBootApplication @ComponentScan // Using a root package also allows the @ComponentScan annotation to be used without needing to specify a basePackage attribute public class SpringBootConfig { public static void main(String[] args) throws Exception { SpringApplication.run(SpringBootConfig.class, args); // it wil start application } }
2.4 Output:
Now type,http://localhost:8080
It will land to default index or landing or welcome page.
