Spring Boot 404 Web服务

Question

我正在通过Spring引导和REST将旧的Spring / SOAP / Java6程序转换为Java 8，但无法正常工作。 我从简单的控制器开始，并添加了摇摇欲坠的功能，但这也不起作用。

我的application.yaml

server:
  port: 30001

spring:
  application:
    name: daissywebservice
  datasource:
    username: USER
    password: PW
    url: jdbc:oracle:thin:serveraddress
  jpa:
    hibernate:
      ddl-auto: none
    properties:
      hibernate:
        dialect: org.hibernate.dialect.Oracle10gDialect
        show_sql: true
        #format_sql: true
  data:
    rest:
      detection-strategy: annotated
  #jackson:
      #serialization:
        #INDENT_OUTPUT: true

management:
  endpoints:
    cors:
      allowed-origins: "*"
#      allowed-methods: GET
    web:
      exposure:
        include: info, health, httptrace

测试控制器

package com.company.project.webservice.controllers;
@RestController
@RequestMapping("/test")
@Api(value = "test", description = "Actions to test")
public class TestController {

    @Autowired
    private TestService testService;

    @GetMapping("/echo/{in}")
    String echo(String in){
        return testService.echo(in);
    }
}

Web服务应用

package com.company.project.webservice;
@SpringBootApplication(
        scanBasePackages = {
        "com.company.subpackage.location.project1"
})
public class WebserviceApplication {
    public static void main(String[] args) {
        SpringApplication.run(WebserviceApplication.class, args);
    }
}

此处的com.company.subpackage.location.project1是TestService所在的位置，这也是一个较旧的spring和Java项目，但这无关紧要。

调用http://localhost:30001/给出

{
  "_links" : {
    "profile" : {
      "href" : "http://localhost:30001/profile"
    }
  }
}

但是当我在控制台中调用http://localhost:30001/swagger-ui.html时，我看到了GET http://localhost:30001/null/swagger-resources/configuration/ui 404 ()并且出现了类似的弹出窗口这个

我想念所有的Web服务都返回404吗？

在我看来，如果要在浏览器上显示数据，则应使用spring-boot-starter-web依赖关系而不是spring-boot-starter-rest 。

当您需要使用API​​连接各种应用程序时， spring-boot-starter-rest很有用。
