整合swagger2生成Restful Api接口文档

swagger Restful文档生成工具 2017-9-30

官方地址：https://swagger.io/docs/specification/about/

官方Github：https://github.com/swagger-api/swagger-core/wiki/Annotations

启动项目，访问http://localhost:8082/swagger-ui.html查看API

注意，此项目示例中，使用了三种ui依赖，每种依赖对应的访问页面不同：

springfox-swagger-ui -> http://localhost:8082/swagger-ui.html
swagger-bootstrap-ui -> http://localhost:8082/doc.html
swagger-ui-layer -> http://localhost:8082/docs.html

使用方法：

1.添加依赖（springfox-swagger2依赖是必须的，三种ui依赖只需要使用一个就行）

<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>

2.创建配置文件Swagger2Config.java

@EnableSwagger2
@Configuration
public class Swagger2Config {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //为当前包路径
                .apis(RequestHandlerSelectors.basePackage("com.zyd.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    //构建 api文档的详细信息函数
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                //页面标题
                .title("Spring Boot 测试使用 Swagger2 构建RESTful API")
                .termsOfServiceUrl("http://localhost/")
                //创建人
                .contact("zhyd")
                //版本号
                .version("1.0")
                //描述
                .description("API 描述")
                .build();
    }
}

注：@EnableSwagger2注解一定不要漏掉

3.编写文档

@RestController
@RequestMapping("/demo")
@Api(value = "测试Swagger2",description="简单的API")
public class UserController {

    @ApiOperation(value = "创建用户", notes = "根据User对象创建用户")
    @ApiImplicitParams({
            @ApiImplicitParam(dataType = "java.lang.Long", name = "id", value = "id", required = true, paramType = "path"),
            @ApiImplicitParam(dataType = "User", name = "user", value = "用户信息", required = true)
    })
    @ApiResponses({
            @ApiResponse(code = 500, message = "接口异常"),
    })
    @RequestMapping(value = "/user/{id}", method = RequestMethod.POST)
    public User insert(@PathVariable Long id, @RequestBody User user) {

        System.out.println("id:" + id + ", user:" + user);
        user.setId(id);

        return user;
    }
}
