Swagger 2 UI not accessible ,Spring boot application deployed on external tomcat - rest

Question

I have copied the war to apache-tomcat-8.0.43/webapps and started tomcat using ./startup.sh. When I try to access http://localhost:8080/swagger-ui.html, I get 404 but it's working when I say mvn spring-boot:run. Am I missing any configuration? Sample code below:
package com.user;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
import static springfox.documentation.builders.PathSelectors.regex;
#SpringBootApplication
#EnableSwagger2
public class UserMicroServicesApplication extends SpringBootServletInitializer {
private static ConfigurableApplicationContext ctx;
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(UserMicroServicesApplication.class);
}
public static void main(String[] args) throws Exception {
ctx = SpringApplication.run(UserMicroServicesApplication.class, args);
}
#Bean
public Docket productApi() {
return new Docket(DocumentationType.SWAGGER_2).select().apis(RequestHandlerSelectors.basePackage("com.user.controller")).paths(regex("/api.*")).build().apiInfo(apiInfo());
}
private ApiInfo apiInfo() {
return new ApiInfo("User API", "User service API.", "V1", "Terms of service", "", "", "");
}
}
controller class

package com.user.controller;
import com.user.service.UserService;
import com.user.vo.UserVO;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.*;
import javax.validation.Valid;
import java.util.List;
#RestController
#RequestMapping(value = "/api")
public class UserController {
private static final Logger logger = LoggerFactory.getLogger(UserController.class);
#Autowired
private UserService userService;
#RequestMapping(value = "/user", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
#ResponseStatus(HttpStatus.CREATED)
#ResponseBody
public UserVO createUser(#RequestBody #Valid UserVO user) {
logger.debug("creating user with email = {}", user);
UserVO updatedUserVO = userService.createUser(user);
logger.debug("user created with id {}", updatedUserVO.getId());
return updatedUserVO;
}
}

You need to add context path to the link.
apache-tomcat-8.0.43/webapps/${war-name}
http://localhost:8080/${war-name}/swagger-ui.html
