Springboot 2.5.0 - Regression - Swagger3 RuntimeException: Could not write JSON

See original GitHub issue

I’m using SpringBoot 2.5.0 and “io.springfox:springfox-boot-starter:3.0.0”.

After upgrade from SpringBoot 2.4.6 to 2.5.0, I get an InvalidDefinitionException error when calling the endpoint: http://localhost:8090/v3/api-docs?group=accounts (the same code worked well in 2.4.6)

The call to v2 works well: http://localhost:8090/v2/api-docs?group=accounts

here is a snippet from my code, configuring Swagger:

    @Bean
    public Docket accountsApiDocket() {

        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("accounts")
                .securitySchemes(List.of(apiKey()))
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.ant("/api/sets/**"))
                .build()
                .apiInfo(ApiInfo.DEFAULT) 
                .enable(enableSwagger);
    }

here is the exception log:

I have tried changing the Docket definition from DocumentationType.SWAGGER_2 to DocumentationType.OAS_30. I also tried adding to my dependencies: implementation "com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.12.3"

But none solved the issue.

Tried opening a SpringBoot issue, but it seems this is internal springfox issue, as explained to me here: https://github.com/spring-projects/spring-boot/issues/26685

Appreciate any help on this.

Thanks, Ori.

We have solved the error by adding the Jackson module for Java 8 date/time to the ObjectMapper used by Springfox in OpenAPI, as follows:

  @Primary
  @Bean
  public JacksonModuleRegistrar openApiJsr310Module() {
    return new SpringFoxOpenApiJsr310Module();
  }

  public static class SpringFoxOpenApiJsr310Module extends OpenApiJacksonModule {
    private static final long serialVersionUID = 5258923350226466432L;

    @Override
    public void maybeRegisterModule(final ObjectMapper mapper) {
      mapper.registerModule(new JavaTimeModule());
      super.maybeRegisterModule(mapper);
    }
  }

@oridool I have the same problem. My problem went away after the example made the date format corresponding to the LocalDateTime (change from 2020-07-07T04:00:00+00:00 to 2020-07-07T04:00)
