Angular 2 and Spring Boot - Deploy to War

Question

Let me just start off by saying, I am new to Maven / Spring and am having a hard time figuring out what to do when my directory does not follow the preferred Maven structure.

Answer 1

After doing a lot of searching, I came across the Maven War Plugin. This allowed me to pull in the necessary frontend files to the backend for the successful creation of my WAR file. The changes that need to be made are as follows:

Backend pom.xml - after the description tags add:

<packaging>war</packaging>

Then, inside the build tags, inside plugins add this plugin:

  <plugin>
    <artifactId>maven-war-plugin</artifactId>
    <configuration>
      <webResources>
        <resource>
          <directory>../frontend/target/frontend</directory>
        </resource>
      </webResources>
    </configuration>
  </plugin>

Other than that, you can keep the existing pom.xml's the same as only the backend pom.xml needs include war packaging. It ended up being a rather simple answer.

Also need to set the base-href in the package.json. Note "build":

"scripts": {
"ng": "ng",
"start": "ng serve --proxy-config proxy.conf.json",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e",
"build": "ng build --base-href=\"./\""
},

                        <resources>
                            <resource>
                                <directory>${basedir}/src/main/angular4Client/dist/angular4Client</directory>
                            </resource>
                        </resources>

            <targetPath>static</targetPath>
        </resource>
    </resources>
</build>
</project>

Then in your angular package.json change like this:

"scripts": {
"ng": "ng",
"start": "ng serve --proxy-config proxy.conf.json",
"build": "ng build --prod",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e"
}

Create a proxy.conf.json file in angular project root :

{
"/api": {
    "target": "http://localhost:8080",
    "secure": false
    }
}

And last things to do, move your angular 4 project into : "src/main/" on SpringBoot project.

Good luck according to this demo : http://javasampleapproach.com/java-integration/integrate-angular-4-springboot-web-app-springtoolsuite

The reference doc contains a detailed description of this. You need <packaging>war</packaging> in both your frontend and backed module pom and some Java code. All described here

With that said, I try to avoid war deploys if not totally necessary. You could just run the built jar file with java -jar your.jar and it will start in an embedded Tomcat.
