How can I deploy a spring-boot webapp with angular 2 frontend (angular-cli build) to Tomcat?

Question

I have a spring-boot web application and I build my frontend with angular-cli. I have set the output directory of my angular build in angular-cli.json to resources/static and I have configured the build script in package.json like this:

"scripts" : {"build": "ng build --base-href /mywebapp", ...}

In the application.properties of the spring-boot configuration I have set the server.contextPath to 'mywebapp'.

But if I build the angular application the included js files of the created index.html in resources/static does not contain the server context path 'mywebapp':

<script type="text/javascript" src="inline.bundle.js"></script>
<script type="text/javascript" src="polyfills.bundle.js"></script>

but I should look like this:

<script type="text/javascript" src="/mywebapp/inline.bundle.js"></script>
<script type="text/javascript" src="/mywebapp/polyfills.bundle.js"></script>

So if I deploy my spring-boot app to tomcat the built index.html is load but it cannot find the imported js files and tries to load the files under http://localhost:8080/ instead of http://localhost:8080/mywebapp/ .

How can I deploy a spring-boot application with an angular-frontend to a tomcat server if I don't want to deploy it under the root directory?

Answer 1

Please take a look at my answer for using '--deploy-url' parameter. https://stackoverflow.com/a/43741602/5633515

In your case, use --deploy-url="/mywebapp/"

I've had the same question, first I've created a pom.xml file and there I've used plugins to convert my package to a war file .

when deploying I've found some issues and good lectures.
