Swagger UI version 3 returning a 404 page but api-docs is working - spring-boot

Question

I am trying to setup swagger-UI to test my springboot REST API rather than using postman however after going through a few tutorials and some questions i can not seem to get past the 404 error when trying to access the html page via my browser.
My dependencies :
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
<version>3.0.0</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>3.0.0</version>
</dependency>
SpringConfig:
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
#Configuration
#EnableSwagger2
public class SpringFoxConfig {
#Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())
.build();
}
}
and my controller
#Controller
#CrossOrigin
#RequestMapping(path = "/api")
public class AppController {
#ResponseBody
#PostMapping(path ="/api")
public String home() {
return "Hello World";
}
#GetMapping(path = { "/api/Teacher/{id}"})
public TeacherPayload getTeacher(#PathVariable(required=false,name="id") String id) throws
Exception{
if (id != null) {
return teacher.getTeacher(id);
} else {
return teacher.getTeachers();
}
....
I changed my port number fro the default 8080 to 3005 but i do not think that should be the problem as i tried reverting back to 8080 to no avail.
Edit: My security config is as follows, note i permitted all paths to bypass the security whilst testing
#Autowired
private JwtAuthenticationEntryPoint jwtAuthenticationEntryPoint;
#Autowired
private UserDetailsServiceImpl jwtUserDetailsService;
#Autowired
private JwtRequestFilter jwtRequestFilter;
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
// configure AuthenticationManager so that it knows from where to load
// user for matching credentials
// Use BCryptPasswordEncoder
auth.userDetailsService(jwtUserDetailsService).passwordEncoder(passwordEncoder());
}
#Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder(12);
}
#Bean
#Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
#Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/authenticate");
web.ignoring().antMatchers("/recoverPortal");
}
#Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
// We don't need CSRF for this example
httpSecurity.cors();
httpSecurity.csrf().disable()
// dont authenticate this particular request
.authorizeRequests().antMatchers(HttpMethod.OPTIONS, "**").permitAll()
.antMatchers("/**").permitAll()
.antMatchers("/newUser").authenticated()
.antMatchers("/newUser").authenticated()
.antMatchers("/admin/**").hasAnyAuthority("USER_ADMIN")
.antMatchers("/resetPassword").authenticated()// all other requests need to be authenticated
.anyRequest().authenticated().and().
// make sure we use stateless session; session won't be used to
// store user's state.
exceptionHandling().authenticationEntryPoint(jwtAuthenticationEntryPoint).and().sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS);
// Add a filter to validate the tokens with every request
httpSecurity.addFilterBefore(jwtRequestFilter, UsernamePasswordAuthenticationFilter.class);
}

Answer 1

What endpoint are you hitting? It should be /swagger-ui/ at the end, not /swagger-ui.html. Also, I think you can omit the springfox-swagger-ui dependency. All I need in my setup is the springfox-boot-starter one.
