spring cloud 学习(10) - 利用springfox集成swagger

对绝大多数程序员而言,写接口文档是一件痛苦的事情,相对文档,他们更愿意写代码。最理想的情况就是:代码即文档!服务开发完成后,部署上去文档就自动生成,没错,这就是springfox + swagger要解决的问题!

swagger号称 THE WORLD'S MOST POPULAR API TOOLING。但swagger默认情况下,仍要单独部署,程序员还是要跑到一个单独的web页面上编辑,写一堆yaml文档,依然不爽。

github上有一个springfox项目,可以在开发rest服务时,只要加一些注解,就自动生成swagger-ui界面,以及相关的文档,而且可以跟spring-boot/spring-cloud无缝集成。

步骤:

一、添加依赖项

    dependencies {
        ...
        compile "io.springfox:springfox-swagger2:2.7.0"
        compile "io.springfox:springfox-swagger-ui:2.7.0"
        ...
    }

  

二、添加swagger配置类

 1 package cn.mwee.order.cloud.service.express.config;
 2 
 3 import org.springframework.context.annotation.Bean;
 4 import org.springframework.context.annotation.Configuration;
 5 import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
 6 import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
 7 import springfox.documentation.builders.ApiInfoBuilder;
 8 import springfox.documentation.builders.PathSelectors;
 9 import springfox.documentation.builders.RequestHandlerSelectors;
10 import springfox.documentation.service.ApiInfo;
11 import springfox.documentation.service.Contact;
12 import springfox.documentation.spi.DocumentationType;
13 import springfox.documentation.spring.web.plugins.Docket;
14 import springfox.documentation.swagger2.annotations.EnableSwagger2;

21 public class SwaggerConfig {

23     @Bean
24     public Docket createRestApi() {
25         return new Docket(DocumentationType.SWAGGER_2)
26                 .apiInfo(apiInfo())
27                 .select()
28                 .apis(RequestHandlerSelectors.basePackage("xxx.controller")) //Controller所在的package
29                 .paths(PathSelectors.any())
30                 .build();
31     }
32 
33     @Bean
34     public WebMvcConfigurerAdapter addResourceHandlers() {
35         return new WebMvcConfigurerAdapter() {
36             @Override
37             public void addResourceHandlers(ResourceHandlerRegistry registry) {
38                 registry.addResourceHandler("swagger-ui.html")
39                         .addResourceLocations("classpath:/META-INF/resources/");
40                 registry.addResourceHandler("/webjars/**")
41                         .addResourceLocations("classpath:/META-INF/resources/webjars/");
42             }
43         };
44     }
45 
46     private ApiInfo apiInfo() {
47         return new ApiInfoBuilder()
48                 .title("express-service online api document")
49                 .description("某某服务")
