Question

While configuring openapi 3 for Spring Boot application, the "/swagger-ui.html" endpoint is not working, it is showing 404 error. Here is the pom.xml file.

Answer 1

I used this dependency for enable swagger ui (openapi 3) specification, for more details refer this link

 <dependency>
  <groupId>org.springdoc</groupId>
  <artifactId>springdoc-openapi-ui</artifactId>
  <version>1.6.13</version>
</dependency>

I hope it will work without this dependency

<dependency>
        <groupId>org.springdoc</groupId>
        <artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
        <version>2.0.0-M4</version>
</dependency>

And swagger ui link will look like this http://localhost:8080/swagger-ui/index.html#/

in documentation this is the format http://server:port/context-path/swagger-ui.html learn more about context path from this link
