java - 无法访问 SwaggerUI index.html 页面，但可以打开 api-docs (Spring - Boot)

Question

我正在尝试一个小应用程序来学习带有 swagger UI 的 Spring Boot。当我运行该程序时，我可以打开显示 json 输出的 http://localhost:8080/api-docs 。但是当我访问 http://localhost:8080/swagger/index.html 时，它给出了 Whitelabel 错误页面。

我遵循的步骤:

1- 从 GitHub 中提供的 swagger-ui 项目复制“dist”文件夹。

2- 将“dist”重命名为“swagger”并将其放入src/main/public

3-将index.html中的路径更改为“/api-docs”。

下面是EclipseLuna IDE的截图以及所有程序代码，

应用程序.java

package com.rajkishan;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

/**
 * Spring Boot Starter Class
 *
 */

@Configuration
@EnableAutoConfiguration
@ComponentScan
@EnableWebMvc
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Greeting.java 是一个普通的 pojo，如 https://spring.io/guides/gs/rest-service/ 中提供的 spring-restful-demo 所示。

GreetingController.java

package com.rajkishan;

import java.util.concurrent.atomic.AtomicLong;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class GreetingController {
    private static final String template = "Hello, %s!";
    private final AtomicLong counter = new AtomicLong();

    @RequestMapping(value = "/greeting", method = RequestMethod.GET, produces = "application/json")
    public Greeting greeting(@RequestParam (value = "name", defaultValue = "World") String name){
        return new Greeting(counter.incrementAndGet(), String.format(template, name));
    }
}

SwaggerConfig.java

package com.rajkishan;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.mangofactory.swagger.configuration.SpringSwaggerConfig;
import com.mangofactory.swagger.plugin.EnableSwagger;
import com.mangofactory.swagger.plugin.SwaggerSpringMvcPlugin;
import com.wordnik.swagger.model.ApiInfo;

@Configuration
@EnableSwagger
public class SwaggerConfig {
private SpringSwaggerConfig swaggerConfig;

@Autowired
public void setSpringSwaggerConfig(SpringSwaggerConfig swaggerConfig){
    this.swaggerConfig = swaggerConfig;
}

@Bean
public SwaggerSpringMvcPlugin customSwaggerPlugin(){
    return new SwaggerSpringMvcPlugin(this.swaggerConfig).apiInfo(apiInfo())
            .includePatterns("/greeting/.*");
}

private ApiInfo apiInfo(){
    ApiInfo apiInfo = new ApiInfo("My Spring Application", 
            "Learning Spring Restful", "termsOfServiceUrl", "contact", "license", "licenseUrl");
    return apiInfo;
 }
}

索引.html

$(function() {
    var url = window.location.search.match(/url=([^&]+)/);
    if (url && url.length > 1) {
        url = decodeURIComponent(url[1]);
    } else {
        url = "/api-docs"
    }
/*Rest of the Code Follows...*/

你能看出我哪里做错了吗？ 也许我错过了什么？

Answer 1

在 Application 类中删除所有注释，并将其替换为 spring-boot 1.2 及更高版本中的 @SpringBootApplication 以及 @EnableAutoConfiguration 的组合> 和 @ComponentScan 用于 1.2.x 以下的启动版本。特别是删除 @EnableWebMvc 注释，因为它会干扰资源的 Spring Boot 自动配置，即提供 swagger-ui 的资源。

此外，您的 swagger-springmvc 依赖项非常过时，您应该至少使用 1.0.2。在相关说明中，您是否考虑过使用 springfox 进行移动？它是下一代 swagger-springmvc，它还支持 swagger 2.0。
