无法使用 Spring Boot 提供静态 index.html

Question

I'm new to Spring and I find it is really hard to get into it. I want to serve a static index.html but it doesn't work.

I used this tutorial but can't access index.html with: http://localhost:8080/ or http://localhost:8080/src/main/public/index.html

IndexHtmlController:

package de.phip1611.springboot_test_1;

import org.springframework.stereotype.Controller;

@Controller
public class IndexHtmlController {}
// due to https://spring.io/blog/2013/12/19/serving-static-web-content-with-spring-boot
// this should be enough..

Answer 1

Can you try the below:

1. Move index.html to src/main/resources/static folder
2. In the application.properties file of spring boot, set server.contextPath to / . (ie server.contextPath=/ )

Answer 2

I have a html file in src/main/resources/static folder and added below in application.yml but it didn't work for me either. On tomcat start ,localhost:8080 shows a 404 and webpage shows whitelabel error. But for localhost:8080/hello.html I see a 200 response code when inspect but no contents of html on webpage .

server:
  servlet:
    context-path: /
  port: 8080

I encounter similar issue. I have spring boot 2.1.3, and only has spring-boot-starter-web as dependency.

By placing index.html under src/main/public folder, and creating a controller that map "/" and simply returns "index.html", i observe same error as the thread starter.

But when I place index.html under src/main/resources/public. It works.

But when I place index.html under src/main/resources. It not works.

I am confused. I thought by default, Spring boot will also look for static content under src/main/public and src/main/resources.
