New web console displays without any style.
http://localhost:7300/ff4j

Can someone point to me a project that has web console + rest API and it builds successfully?

So far I tried the following project(and many more) and was unsuccessful:
ff4j-sample-springboot-starter
ff4j-sample-springboot
ff4j-sample-springboot2
ff4j-sample-springboot-jdbc

Once I switch the version from <ff4j.version>1.9-SNAPSHOT</ff4j.version> to <ff4j.version>1.8.4</ff4j.version> it runs and the REST API works but the web console doesn't work.
Once I hit http://localhost:8080/ff4j-web-console/home
it gives me below message in the browser:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

I am new to FF4J and started with hello world application. I wrote a sample spring boot project and added dependency for ff4j-spring-boot-starter and ff4j-web modules in my pom.xml.

However, when I run the application, the FF4J web console is displayed distracted.
Below is my pom.xml for your reference

Below is the web console that i can see

Below are my configuration classes.

Please check and help what i am missing and how do i get web console properly.

Hi, I am trying to embed the ff4j functionality in my existing spring boot application
Followed all the steps as per the ff4j release 1.8.6, jumped to spring boot 2.2.7, still getting the below error

We do have our own WebSecurityConfig, where i tried to add the ff4j-wen-console/* to permitted URL, still cant get rid of the error.

.antMatchers("/ff4j-web-console/*").permitAll();

Can you please let me know the issue, what i am missing here. Thanks

hi,
when i integrate ff4j according to this sample, i got ,
Caused by: org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'swaggerConfig' for bean class [org.ff4j.spring.boot.web.api.config.SwaggerConfig] conflicts with existing, non-compatible bean definition of same name and class [com.phoenix.common.swagger.SwaggerConfig]

how to fix this, thanks

When trying to access the Swagger UI for documentation I'm getting the following in my browser:

{"uptime":"0 day(s) 0 hours(s) 2 minute(s) 42 seconds"","autocreate":true,"version":"1.8.11","featuresStore":{"type":"org.ff4j.audit.proxy.FeatureStoreAuditProxy","numberOfFeatures":5,"numberOfGroups":2,"features":["AwesomeFeature","first","second","third","forth"],"groups":["GRP0","GRP1"],"cache":null},"eventRepository":{"type":"org.ff4j.audit.repository.InMemoryEventRepository","eventsPie":{"title":"Total Hit Counts FROM 20211211 TO 20211212","sectors":[]},"barChart":{"title":"HitCounts Distribution FROM 20211211 TO 20211212","labels":[],"series":[]},"hitCount":0},"authorizationsManager":null}

This is on URL: http://localhost:8080/api/ff4j/

Under project: ff4j-sample-springboot2x

Is there a missing configuration or setup step?

My expectation is the swagger for the ff4j-sample-springboot2x project would look similar to the following:

https://ff4j.herokuapp.com/swagger-ui.html

Thanks,
Travis

Hi there,

thank you for uploading the ff4j-sample-simplejdbc sample.
But i am not able to get the audit working.

Do you know what the reason could be?

Thanks,

The spring-boot samples use a rather old version of ff4j. The version should be updated to reflect recent API changes.

Hi,

Do you have any sample to showcase ff4j with microservices implementation. Basically, how we can manage features in ff4j database and the same features should be available for multiple services running on multiple JVMS.

Hi there,

sorry for asking again.

Is there a sample project which combines the REST API (with Swagger doc), Spring jdbc and the admin web console?
Like the other project you created (ff4j-sample-simplejdbc)?

Or how can I integrate swagger doc into the ff4j-sample-jdbc example?

Thank you in advance.

When using the latest spring boot sample and trying to edit either a property or a feature, the modal dialog box does not come up.

I tested with chrome and firefox and ff4j 1.6.5.

If I delete the templates folder, delete css, js, img, fonts folders from resources/static and copy the resources from the ff4j-sample-web/src/main/webapp project then everything seems functional but the button colors for edit/remove in property and feature list does not render correctly. The demo/ url does not work either since I guess it uses the templates for that.
