无法使用 spring boot 在 jax rs 中显示 index.html

Question

I am trying to create a simple app with jax rs, springboot, angular.

I have placed the index.html in static folder, but while hitting the url localhost:8080/index.html or localhost:8080 it's throwing 404 not found error through the custom exception handler. I have added index.html as welcome-file-list.

I have a controller class but i have not written any specific method to handle it.

Also i want to display error specific page with message details.

Definitely i am missing something but not getting any pointer to find it out. Please help.

Do i need to configure web.xml explicitly for this?

Answer 1

Add

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

To your pom.xml file, spring boot auto configure all the rest.

Answer 2

I know this is older, but to expand on Itsik's answer I found this answer via this other answer to be very helpful in explaining this.

Summed up, if you want to be able to serve up resources/static/index.html AND use JAX-RS/jersey for api endpoints, include both spring-boot-start-web and spring-boot-starter-jersey . In your JerseyConfig add @ApplicationPath("/api") or whatever subpath you want all your jax-rs rest endpoints to live under. Then you will be able to have the best of both worlds.
