I just add a GlobalExceptionHandler with @ControllerAdvice and when i try to access Swagger UI at http://localhost:8080/swagger-ui/index.html?configUrl=/v3/api-docs/swagger-config#/ a get a message in the UI: "Failed to load API definition"and an exception in console.
Before adding the GlobalExceptionHandler implementation shown below, i could access Swagger UI with no problem.
Here is my GlobalExceptionHandler.java :
@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(ResourceNotFoundException.class)
public ResponseEntity<ExceptionResponse> resourceNotFound(ResourceNotFoundException ex) {
ExceptionResponse response = new ExceptionResponse();
response.setErrorCode("NOT_FOUND");
response.setErrorMessage(ex.getMessage());
response.setTimestamp(LocalDateTime.now());
return new ResponseEntity<>(response, HttpStatus.NOT_FOUND);
}
}
My ExceptionResponse.java:
@AllArgsConstructor
@NoArgsConstructor
@Getter
@Setter
public class ExceptionResponse {
private String errorMessage;
private String errorCode;
private LocalDateTime timestamp;
}
My ExceptionResponse.java:
@AllArgsConstructor
@NoArgsConstructor
@Getter
@Setter
@ResponseStatus(value= HttpStatus.NOT_FOUND)
public class ResourceNotFoundException extends RuntimeException {
public ResourceNotFoundException(String message){
super(message);
}
}
My OpenApiConfig.java (in case is needed) where i create Swagger:
@SecurityScheme(
name = "bearerAuth",
type = SecuritySchemeType.HTTP,
bearerFormat = "JWT",
scheme = "bearer"
)
public class OpenApiConfig {
@Bean(name = "tutofastOpenApi")
public OpenAPI tutofastOpenApi() {
// Available at
// http://localhost:8080/swagger-ui/index.html?configUrl=/v3/api-docs/swagger-config
return new OpenAPI()
.components(new Components())
.info(new Info().title("TutoFast Application API Documentation").description(
"TutoFast API implemented with Spring Boot RESTful service and documented using springdoc-openapi and OpenAPI 3."));
}
}
My WebSecurityConfig.java in case is needed:
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsServiceImpl userDetailsService;
@Autowired
private AuthEntryPointJwt unauthorizedHandler;
@Bean
public AuthTokenFilter authenticationJwtTokenFilter() {
return new AuthTokenFilter();
}
@Override
public void configure(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
authenticationManagerBuilder.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Override
public void configure(WebSecurity web) throws Exception {
//Ignore Swagger UI
web.ignoring().antMatchers("/v3/api-docs/**",
"/configuration/ui",
"/swagger-ui/**",
"/swagger-resources/**",
"/configuration/security",
"/swagger-ui.html",
"/webjars/**");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.cors().and().csrf().disable()
.exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
.authorizeRequests()
.antMatchers("/api/auth/**").permitAll()
.antMatchers("/api/test/**").permitAll()//TODO :MODIFICAR !!!!!!!
.antMatchers("/api/user/**").permitAll()
.antMatchers("/api/courses/**").permitAll()
.antMatchers("/api/plans/**").permitAll()
.antMatchers("/api/subscriptions/**").permitAll()
.antMatchers("/api/sessions/**").permitAll()
.anyRequest().authenticated();
http.addFilterBefore(authenticationJwtTokenFilter(), UsernamePasswordAuthenticationFilter.class);
}
}
And this is the exception in got in console when i try to access Swagger UI:
