So, the answer is probably super easy, but I just can't seem to figure it out.
I have set up a REST webservice, according to this tutorial: https://spring.io/guides/gs/rest-service/ and have set up the Requestmapping and everything using postman, and that end is working like I intended to.
I am setting up my site locally, but when I try to send a get request with jquery, I am receiving the following error: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.
So I have understood that the problem is that I am trying to run my html from file:// and that the solution is to run it from localhost on the tomcat server and found this answer in another topic: Deploying just HTML, CSS webpage to Tomcat
However, I cannot find such a webapps folder, and I am assuming it is because my tomcat server is deployed using maven and springboot. So how do I deploy my html/js on the tomcat server when it is deployed this way?
I am working on a mac and with IntelliJ.
In your spring boot application you can put your index.html file in src/main/resources/static directory and it will be served by the application.
Also you may try to configure CORS in spring boot, see this answer for links.
If you are deploying normal web applications like jee apps you do it by placing your war file in webapps folder. The web apps folder is inside your tomcat
But for for intellij-idea go through this, it should work:
Where is my app placed when deploying to Tomcat?

I am a little out of my league on this one as I am still getting familiar with everything Springboot. Onto my problem...
I am unable to access actuator for an application that is running in a fat jar file on an application server. All works great when I run the application locally through Eclipse as I am perfectly able to access a couple of the endpoints (health, logfile) via a browser and Postman.
However, when I attempt to access those same endpoints (via curl, a browser or Postman) using the application server's url, I get a 404. I am able to access other custom written apis within the application with no issue, just not actuator apis.
I know I am missing something very obvious, but cannot figure out what that is.
Good - http://localhost:9091/actuator/health --> from a browser or Postman
Not good - http://my-app-testserver-01:9090/actuator/health or curl localhost:9090/actuator/healthand both yield the below error. NOTE that the curl is performed on the application server.
"timestamp":"2022-06-30T20:57:12.191+00:00","status":404,"error":"Not Found","path":"/actuator/health"
What else? Oh yeah, below is a snippet from my yml file pertaining to actuator and I believe that is ok.
Any insight on this is greatly appreciated. Thank you.
management:
server:
port: 9090
endpoints:
web:
exposure:
include: "health,info,logfile" ```
This is all set now. I was setting up the application on a new server and had to have the ports opened up for me. Once that was done I was able to access the Actuator apis with no issues.
I have a Springboot project and it has a api which I can invoke from postman.
When I run the application using Main Class I'm able to hit the endpoint and get response.
But if I deploy it on tomcat using war of project the same endpoint says 404!
What am I missing?
There can be multiple possibilities
You didn't extended your application class to SpringBootServletInitializer. In this case, spring boot application will not be deployed to tomcat. To fix this add "extends SpringBootServletInitializer" to your main application class
You are hitting wrong url. Make sure you append your aplication name to url. Example - if http://localhost:8080/data works in your local, and your application name is app, you have to hit http://{{serverip:port}}/app/data when deployed
There is something wrong in application properties like DB configured is local and not accessible from tomcat etc. To check such issues, check your tomcat log file (/{{tomcat dir}}/logs/catalina.out
I created spring boot api with gradle build. everything working fine in my local.
I deployed angular app in Sites/DefaultsTest in IIS web server. it run in https://example.app.com/app
SpringBoot API base path is '/api'
I want to deploy spring boot api in same windows server machine and should able to access through Angular App globally.
please guide me.
IIS WebServer Dashboard
As far as I know, the spring boot API is a java web application, we don't suggest you directly hosted the java web application in the IIS.
I suggest you could try to install a docker or using tomcat to host the application, then you could use IIS reverse proxy to redirect the request to that API to get the result.
More details about how host the spring boot application on the docker, you could refer to below article.

I've asked the same question at Vaadin's forum, but noone responds there, so maybe someone here can help.
I've developed a Vaadin Spring Boot app that works perfectly when I run it as is, but when I tried to run it behind Apache Proxy (so that requests to http://website/vaadin-app/ are forwarded to http://website:8080), I've got a problem: UI is rendered successfully, but the data can't be fetched from the server. The error is: The requested URL /vaadinServlet/UIDL/ was not found on this server.
It looks like Vaadin doesn't make relative requests, but rather absolute ones, so it tries to load http://website/vaadinServlet/UIDL/ instead of http://website/vaadin-app/vaadinServlet/UIDL/
What kind of configuration should I add to address this issue?
We have created spring application, this is running in tomcat and resources(css, images and js) are coming from apache. We are trying to enable ssl but we are not able to get resources from apache. In console getting exception like resources could not be loaded. Can any one please help me.
You should probably use Apache as a reverse proxy to tomcat. This way, everything will go through Apache. Resources will be served directly, and requests to the appication will be proxied to your tomcat server:
