springboot整合swagger2

swagger2用于通过配置的方式生成接口文档

引入jar包

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.4.0</version>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.4.0</version>
        </dependency>

配置swagger2启动类

@Configuration
@EnableSwagger2
public class Swagger2 {
    @Bean
    public Docket createRestApi(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //为当前包路径
                .apis(RequestHandlerSelectors.basePackage("com.example.learn.swagger2"))
                .paths(PathSelectors.any())
                .build();
    }

    //构建 api文档的详细信息函数,注意这里的注解引用的是哪个
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                //页面标题
                .title("Spring Boot 测试使用 Swagger2 构建RESTful API")
                //创建人
                .contact(new Contact("MarryFeng", "http://www.baidu.com", ""))
                //版本号
                .version("1.0")
                //描述
                .description("API 描述")
                .build();
    }
}

配置实体类和controller

model:

@Data
@AllArgsConstructor
@NoArgsConstructor
@ApiModel("用户")
public class User {
    @ApiModelProperty("用户baseId")
    private Integer baseId;
    @ApiModelProperty("用户id")
    private String userId;
    @ApiModelProperty("用户名")
    private String username;
    @ApiModelProperty("密码")
    private String password;
}

controller:

@RestController
@RequestMapping("/api")
@Api("swaggerDemoController测试api")
public class SwaggerDemoController {

    @Autowired
    private UserService userService;

    private static final Logger logger= LoggerFactory.getLogger(SwaggerDemoController.class);

    @ApiOperation(value = "根据id查询用户", notes = "查询用户信息")
    @ApiImplicitParam(name = "id",value = "用户id",required = true)
    @RequestMapping(value = "/getuser",method = RequestMethod.GET)
    public User getUser(@PathVariable String id){
        return userService.getUser(id);
    }
}
