1.  maven中引入jar包，不同版本的swagger可能页面效果不一样。

<dependency>
                <groupId>io.springfox</groupId>
                <artifactId>springfox-swagger2</artifactId>
                <version>2.9.1</version>
            </dependency>
    
            <dependency>
                <groupId>io.springfox</groupId>
                <artifactId>springfox-swagger-ui</artifactId>
                <version>2.9.1</version>
            </dependency>

2.启动类加上@EnableSwagger2注解，并在同路径下创建全局配置类。

import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.bind.annotation.RequestMethod;
    import springfox.documentation.builders.ApiInfoBuilder;
    import springfox.documentation.builders.PathSelectors;
    import springfox.documentation.builders.RequestHandlerSelectors;
    import springfox.documentation.builders.ResponseMessageBuilder;
    import springfox.documentation.schema.ModelRef;
    import springfox.documentation.service.ApiInfo;
    import springfox.documentation.service.ResponseMessage;
    import springfox.documentation.spi.DocumentationType;
    import springfox.documentation.spring.web.plugins.Docket;
    
    import java.util.ArrayList;
    import java.util.List;
    
    @Configuration
    public class Swagger2Config {
    
    
        @Bean
        public Docket createRestApi() {
            //这块是定义全局返回码
            List<ResponseMessage> responseMessageList = new ArrayList<>();
            responseMessageList.add(new ResponseMessageBuilder().code(404).message("找不到资源").build());
            responseMessageList.add(new ResponseMessageBuilder().code(409).message("业务逻辑异常").build());
            responseMessageList.add(new ResponseMessageBuilder().code(400).message("网络协议错误").build());
            responseMessageList.add(new ResponseMessageBuilder().code(500).message("服务器内部错误--->Exception").build());
            responseMessageList.add(new ResponseMessageBuilder().code(502).message("nginx异常").build());
            return new Docket(DocumentationType.SWAGGER_2).globalResponseMessage(RequestMethod.GET, responseMessageList)
                    .globalResponseMessage(RequestMethod.POST, responseMessageList)
                    .globalResponseMessage(RequestMethod.PUT, responseMessageList)
                    .globalResponseMessage(RequestMethod.DELETE, responseMessageList)
                    .apiInfo(apiInfo())
                    .select()
                    .apis(RequestHandlerSelectors.basePackage("order.controller"))//包的根路径
                    .paths(PathSelectors.any())
                    .build();
        }
    
        private ApiInfo apiInfo() {
            return new ApiInfoBuilder()
                    .title("ORDER-PROVIDER")//接口文档标题设置
                    .description("API接口列表")//描述
                    .version("1.0")//版本号
                    .build();
        }
    }

3.在相应的controller层写对应注解。一般来说接口文档关注的几点，网络协议，接口入参，接口出参，方法类型。拿一个conteller举例。分几步：

（1）对整个controller类加上@Api注解标识为一个swagger管理的类。

（2）方法修饰，加上@ApiOperation对方法进行说明。主要参数如图

（3）入参修饰。使用@ApiImplicitParams和@ApiImplicitParam一起封装。如果入参参数含有实体对象，其中@ApiImplicitParam的name属性就定义为类的类型，这样才能展示。如果为基本类型，name即为属性名称。

（4）出参修饰。可以使用@ApiResponses和@ApiResponse一起封装。如果返回中含有泛型实体(目前来说接口返回都是一个基本返回对象包装实例数据对象)。此时想要展现出来，就需要在接口方法处指定返回的泛型，然后在@ApiResponse注解中不要使用Response属性指定返回类型。

@RestController
    @RequestMapping("/manager/blacklist")
    @Api("黑名单管理")
    public class BlackListController{
        @Autowired
        private BlackListService blackListService;
    
        /**
         * 分页列表
         */
        @ApiOperation(value = "list",notes = "分页列表查询",httpMethod = "POST")
        @ApiImplicitParams({
                @ApiImplicitParam(paramType = "query",name = "BlackListDto",value = "黑名单实体",required = true)
                @ApiImplicitParam(paramType = "query",name = "tokenId",value = "鉴权Id",required = true)
        })
        @ApiResponses({
                @ApiResponse(code = 200,message = "成功" ),
                @ApiResponse(code= 500,message = "服务错误")
        })
        @PostMapping("/list")
        public ResponeModel<BlackListDto> list(@RequestBody BlackListDto blackListDto,String tokenId){
            PageInfo<BlackListDto> list = blackListService.pageList(blackListDto);
            return ResponeModel.ok(list);
        }
    }

（5）实体修饰。要想在swagger界面展现出每个字段对应的说明。最后还需要在实体类中定义一层。使用@ApiModel定义类和@ApiModelProperty定义属性。

import com.fasterxml.jackson.annotation.JsonFormat;
    import io.swagger.annotations.ApiModel;
    import io.swagger.annotations.ApiModelProperty;
    import io.swagger.annotations.ApiParam;
    import lombok.Data;
    
    import java.util.Date;
    
    /**
     * 黑名单表
     * 
     * @email ${email}
     * @date 2021-05-13 14:24:39
     */
    @Data
    @ApiModel(value = "BlackListDto",description = "黑名单实体信息")
    public class BlackListDto  {
    	private static final long serialVersionUID = 1L;
    
    	/**
    	 * 主键id
    	 */
    	@ApiModelProperty(value = "主键ID",name = "id")
    	private Long id;
    	/**
    	 * 买家编号
    	 */
    	@ApiModelProperty(value = "买家编号",name = "buyerNo")
    	private String buyerNo;
    	/**
    	 * 备注，进入黑名单的原因
    	 */
    	@ApiModelProperty(value = "备注",name = "remarks")
    	private String remarks;
    	/**
    	 * 黑名单状态：1未恢复  2已恢复
    	 */
    	@ApiModelProperty(value = "黑名单状态",dataType = "Integer")
    	private Integer status;
    	/**
    	 * 字符型保留字段1.
    	 */
    	@ApiModelProperty(value = "字符型保留字段1",name = "fldS1")
    	private String fldS1;
    	/**
    	 * 字符型保留字段2.
    	 */
    	@ApiModelProperty(value = "字符型保留字段2",name = "fldS2")
    	private String fldS2;
    	/**
    	 * 字符型保留字段3.
    	 */
    	@ApiModelProperty(value = "字符型保留字段3",name = "fldS3")
    	private String fldS3;
    	/**
    	 * 数值型保留字段
    	 */
    	@ApiModelProperty(value = "数值型保留字段1",name = "fldN1")
    	private Integer fldN1;
    	/**
    	 * 数值型保留字段
    	 */
    	@ApiModelProperty(value = "数值型保留字段2",name = "fldN2")
    	private Integer fldN2;
    	/**
    	 * 创建时间
    	 */
    	@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss",timezone = "GMT+8",locale = "zh")
    	@ApiModelProperty(value = "创建时间",name = "createDate")
    	private Date createDate;
    	/**
    	 * 修改人
    	 */
    	@ApiModelProperty(value = "修改人",name = "updateBy")
    	private String updateBy;
    	/**
    	 * 修改时间
    	 */
    	@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss",timezone = "GMT+8",locale = "zh")
    	@ApiModelProperty(value = "修改时间",name = "updateDate")
    	private Date updateDate;
    	/**
    	 * 创建人ID
    	 */
    	@ApiModelProperty(value = "创建人",name = "createBy")
    	private String createBy;
    }
