Spring boot swagger2 404

问题

I am converting an older java 6 SOAP project to java 8 with spring boot and swagger. I used to be able to use swagger before autowiring a service but now I get a white page in browser with errors rapidly appearing in the console of chrome.

pom.xml

<dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.8.0</version>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>2.8.0</version>
    </dependency>

application.yaml

server:
port: 30001

In the url there is localhost/null/swagger so I assume the problem is there somewhere, I changed the context to test and then the error was localhost/test/null/swagger..

@SpringBootApplication(scanBasePackages = {
        "com.company.location.myprogram"
})
public class WebserviceApplication {
