# 1. 导入Pom包 #

<dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.7.0</version>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>2.7.0</version>
    </dependency>

# 2. 编写配置文件 #

在`application.properties`中设置`swagger.enable`为true即可开启swagger，在生产环境设置为false则可关闭swagger

@Configuration
    @EnableSwagger2
    @ConditionalOnProperty(value = "swagger.enable", havingValue = "true")
    public class SwaggerConfig {
    
        @Bean
        public Docket createRestApi() {
            return new Docket(DocumentationType.SWAGGER_2)
                    .apiInfo(apiInfo())
                    .select()
                    .apis(RequestHandlerSelectors.basePackage("cn.ntshare.laboratory.controller"))
                    .paths(PathSelectors.any())
                    .build();
        }
    
        private ApiInfo apiInfo() {
            // 填写文档开发者信息
            Contact contact = new Contact("3795", "https://www.ntshare.cn", "seven.iwi@gmail.com");
            return new ApiInfoBuilder()
                    .title("Swagger示例标题")
                    .description("这是Swagger示例描述")
                    .contact(contact)
                    .version("1.0.0")
                    .build();
        }
    }

# 3. 测试 #

## 3.1 User.java ##

@Setter
    @Getter
    @AllArgsConstructor
    @NoArgsConstructor
    public class User {
    
        @ApiModelProperty(value = "ID", example = "132")
        private String id;
    
        @ApiModelProperty(value = "用户名", example = "小明")
        private String username;
    }

*  @ApiModelProperty作用于对象属性上，value声明该字段的含义，example将在Swagger中返回一个示例值

## 3.2 TestController.java ##

@RestController
    @RequestMapping("/test")
    @Slf4j
    @Api(tags = "测试接口")
    public class TestController {
    
        @GetMapping("/methodA")
        @ApiOperation("测试Swagger功能")
        @ApiImplicitParams({
                @ApiImplicitParam(name = "id", value = "id", defaultValue = "111", required = false, paramType = "query"),
                @ApiImplicitParam(name = "username", value = "用户名", defaultValue = "Tom", required = false, paramType = "query"),
        })
        @ApiResponses({
                @ApiResponse(code = 200, message = "请求成功", response = User.class)
        })
        public User test(@RequestParam(value = "id", defaultValue = "111", required = false) String id,
                           @RequestParam(value = "username", defaultValue = "Tom", required = false) String username) {
            return new User(id, username);
        }
    }

*  @Api作用了类上，作为协议集描述（控制器的描述）
 *  @ApiOperation，描述该接口方法
 *  @ApiImplicitParams，参数集
 *  @ApiImplicitParam，参数的具体描述
 *  @ApiResponses，接口的返回对象集
 *  @ApiResponse，接口的返回值模型，code：请求返回值，message：请求返回消息，response：返回值中的类型

# 4. 访问 #

运行项目，访问地址为：`ip:post/项目路径前缀/swagger-ui.html`，  
如：`http://localhost:8080/laboratory/swagger-ui.html`

特别注意，如果配置了项目路径前缀的话，一定不要忘了！
