本文介绍了在SpringBoot项目中，如何使用RespBodyUtil工具类来处理接口的响应体，以方便返回统一格式的数据。

import lombok.Data;

/**
 * 用户返回统一接口
 */
@Data
public class RespBody {

    private String code;

    private Object body;

    private String message;

    public RespBody() {
    }



    public Object getBody() {
        return body;
    }

    void setBody(Object body) {
        this.body = body;
    }



    public static RespBodyBuilder builder(){
        return new RespBodyBuilder();
    }


    public static final class RespBodyBuilder {
        private String code;
        private Object body;
        private String message;

        private RespBodyBuilder() {
        }

        public static RespBodyBuilder aRespBody() {
            return new RespBodyBuilder();
        }

        public RespBodyBuilder code(String code) {
            this.code = code;
            return this;
        }

        public RespBodyBuilder body(Object body) {
            this.body = body;
            return this;
        }

        public RespBodyBuilder message(String message) {
            this.message = message;
            return this;
        }

        public RespBody build() {
            RespBody respBody = new RespBody();
            respBody.setBody(body);
            respBody.code = this.code;
            respBody.message = this.message;
            return respBody;
        }
    }
}

RespBodyUtil 工具类

public abstract class RespBodyUtil {

    public static RespBody success(@Nullable Object body) {
        return RespBody.builder().code(StatusCodeEnums.SUCCESS.getCode()).body(body).message("操作成功").build();
    }

    public static RespBody fail(BusinessException exception) {
        return RespBody.builder().code(StatusCodeEnums.CUSTOMIZED_BUSINESSEXCEPTION.getCode()).body(ExceptionResp.valueOf(exception)).message(exception.getMessage()).build();
    }

    public static RespBody fail(Exception exception) {
        return RespBody.builder().code(StatusCodeEnums.SYSTEM_ERROR.getCode()).message("系统异常").build();
    }

    public static RespBody tokenAuthError() {
        return RespBody.builder().code(StatusCodeEnums.Token_AUTH_ERROR.getCode()).message("session鉴全失败").build();
    }

}
