Springboot ReactJS package

Question

I am trying to package the springboot and reactjs and deploy it to tomcat 9. My problem is when I accessing my frontend, it showing a blank page. Is there anyone knows this?

pom.xml ` com.github.eirslett frontend-maven-plugin 1.14.2 v18.17.1 9.6.7 src/main/client target/classes/static Install node and npm install-node-and-npm generate-resources

client forwarder `@Controller public class ClientForwarderController {

@RequestMapping("/{path:[^\\.]+}/**")
public String forward() {
    return "forward:/";
}`

I want to merge the springboot and reactjs in one build.
