Why is it that when I introduce modeler related packages, all the mapped url addresses are not accessible?

[sam]

I introduced compile(‘org.flowable:flowable: spring-boot-starter-basic:6.2.1’) in my springboot project.
After the compile(‘org.flowable:flowable-ui-modeler-logic:6.2.1’), I found that the url address of controller mapping in my project was not accessible. Why?Is it where I’m not configured?Thank you very much!
