• 引入Maven依赖

  <dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-swagger2</artifactId>
      <version>2.2.2</version>
  </dependency>
  <dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-swagger-ui</artifactId>
      <version>2.2.2</version>
  </dependency>
  

• 创建Swagger配置类

  @Configuration
  @EnableSwagger2
  public class Swagger2Configuration {
      @Bean
      public Docket buildDocket() {
          return new Docket(DocumentationType.SWAGGER_2)
                  .select()
                  .apis(RequestHandlerSelectors.basePackage("com.xxx.web.controller")) //要扫描的API(Controller)基础包
                  .paths(PathSelectors.any()) // and by paths
                  .build()
                  .apiInfo(buildApiInf());
      }
      private ApiInfo buildApiInf() {
          return new ApiInfoBuilder()
                  .title("Spring Boot中使用Swagger2 UI构建API文档")
                  .contact("test")
                  .version("1.0.0")
                  .build();
      }
  }
  

• 创建 Controller 并使用 swagger 构建 API

  • @Api注解用来表述该服务的信息，如果不使用则显示类名称.
  • @ApiOperation注解用于表述接口信息
  • @ApiParam注解用于描述接口的参数

  @RestController
  @RequestMapping("article")
  @Api(value = "文章服务",description="提供 增删改查 API")
  public class ArticleController {
  
      @Autowired
      private ArticleService articleServiceImpl;
  
      @PostMapping
      @ApiOperation("添加")
      public WebResult save(@RequestBody Article article) {
          return WebResult.ok(articleServiceImpl.save(article));
      }
  
      @PutMapping
      @ApiOperation("修改")
      public WebResult update(@RequestBody Article article) {
          return WebResult.ok(articleServiceImpl.update(article));
      }
  
      @DeleteMapping("{id}")
      @ApiOperation("删除")
      public WebResult delete(@ApiParam("文章id") @PathVariable String id) {
          return WebResult.ok(articleServiceImpl.remove(id));
      }
  
      @GetMapping("{id}")
      @ApiOperation("查找")
      public WebResult get(@ApiParam("文章id") @PathVariable String id) {
          return WebResult.ok(articleServiceImpl.get(id));
      }
  
  }
  

• 为Model(JSON)添加注释 (这一步可以不要)

  @Entity
  @ApiModel("Article(文章实体)")
  public class Article extends BaseEntity {
  
      /**
       * 标题
       */
      @ApiModelProperty("标题")
      private String title;
  
      /**
       * 正文
       */
      @Type(type = "text")
      @ApiModelProperty("正文")
      private String content;
  
      /**
       * 发表时间
       */
      @JsonFormat(pattern = "yyyy/MM/dd")
      @ApiModelProperty("发表时间")
      private LocalDateTime publishedTime;
  
      /**
       * 作者
       */
      @ApiModelProperty("作者")
      private String author ;
  
      public Article() {
          this.publishedTime = LocalDateTime.now();
      }
  
      public Article(String title , String content) {
          this.title = title ;
          this.content = content ;
          this.publishedTime = LocalDateTime.now();
      }
  
      public String getTitle() {
          return title;
      }
  
      public void setTitle(String title) {
          this.title = title;
      }
  
      public LocalDateTime getPublishedTime() {
          return publishedTime;
      }
  
      public void setPublishedTime(LocalDateTime publishedTime) {
          this.publishedTime = publishedTime;
      }
  
      public String getAuthor() {
          return author;
      }
  
      public void setAuthor(String author) {
          this.author = author;
      }
  
      public String getContent() {
          return content;
      }
  
      public void setContent(String content) {
          this.content = content;
      }
  }
  

• ok,重新启动下Application，访问 http://localhost:8080/swagger-ui.html (“项目访问链接”+“/swagger-ui.html”)。即可看到 swagger 帮我生成的 API文档。
