本文介绍了如何在Java项目中使用Springfox库创建RESTful API接口，并通过Lombok简化对象映射，重点讲解了ResultCode接口和R类的设计，用于统一API的状态管理和响应格式。

首先先导入类所需有的包


        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>

        <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.7.0</version>
        </dependency>
        
        <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.7.0</version>
        </dependency>

在工具类中创建接口与类

ResultCode 代码如示（可以根据个人习惯进行设置状态码）

public interface ResultCode {
    public static Integer SUCCESS = 20000;  //成功
    public  static Integer ERROR = 20001;   //失败
}

R 代码如示

@Data
public class R {

    @ApiModelProperty(value = "是否成功")
    private  Boolean success;

    @ApiModelProperty(value = "返回码")
    private Integer code;

    @ApiModelProperty(value = "返回消息")
    private  String message;

    @ApiModelProperty(value = "返回数据")
    private Map<String,Object> data = new HashMap<String,Object>();

    //构造方法私有化
    private  R(){}

    //成功静态方法
    public static R ok(){
        R r= new R();
        r.setSuccess(true);
        r.setCode(ResultCode.SUCCESS);
        r.setMessage("成功");
        return r;
    }


    //失败静态方法
    public static R error(){
        R r= new R();
        r.setSuccess(false);
        r.setCode(ResultCode.ERROR);
        r.setMessage("失败");
        return r;
    }

    public R success(Boolean success){
        this.setSuccess(success);
        return this;
    }

    public R message(String message){
        this.setMessage(message);
        return this;
    }

    public R code(Integer code){
        this.setCode(code);
        return this;
    }

    public R data(String key, Object value){
        this.data.put(key, value);
        return this;
    }

    public R data(Map<String, Object> map){
        this.setData(map);
        return this;
    }
}
