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", "[email protected]");
        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！
