How to add Swagger UI to microservice application in jhipster generator?

Question

How would I enable swagger ui in jhipster generator for microservice application? I notice it only supports swagger for gateway, so how do I configure swagger ui so that it works on microservice application as well?

Configuration Progress

Added springfox-swagger2 and springfox-swagger-ui dependencies to pom.xml

<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.9.2</version>
    </dependency>

<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>2.9.2</version>
    </dependency>

Created this class and added to spring directory

    // Only select apis that matches the given Predicates.
    private Predicate<String> paths() {

        return Predicates.and(
