前后端分离-定义响应格式化数据

一、统一响应结果实体类：

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import lombok.experimental.Accessors;

import java.io.Serializable;

/**
 * @ClassName: Result
 * @Description:
 * @Version: v1.0.0
 * @Author: greatesky
 * @Date: 2019/9/7 11:22
 * Modification History:
 * Date             Author      Version     Description
 * -------------------------------------------------------------
 * 2019/9/7      greatesky      v1.0.0      创建
 */
@ApiModel(value = "统一响应结果")
@Data
@Accessors(chain = true)
public class Result<T> implements Serializable {
    private static final long serialVersionUID = -5336210741362413873L;

    @ApiModelProperty(value = "接口调用是否成功，true = 成功，false = 不成功")
    private Boolean isSuccess;

    @ApiModelProperty(value = "响应结果标识符")
    private String code;

    @ApiModelProperty(value = "响应结果说明")
    private String message;

    @ApiModelProperty(value = "响应数据")
    private T data;
}

二、响应结果

**
 * @ClassName: ResultGenerator
 * @Description: Result 生成工具
 * @Version: v1.0.0
 * @Author: greatesky
 * @Date: 2019/9/7 11:27
 * Modification History:
 * Date             Author      Version     Description
 * -------------------------------------------------------------
 * 2019/9/7      greatesky      v1.0.0      创建
 */
public class ResultGenerator<T> {

    public static Result genSuccessResult() {
        return new Result()
                .setCode("200")
                .setMessage("成功")
                .setIsSuccess(true);
    }

    public static <T> Result genSuccessResult(T data) {
        return new Result()
                .setIsSuccess(true)
                .setCode("200")
                .setMessage("成功")
                .setData(data);
    }

    public static Result genSuccessResult(String code, String message) {
        return new Result()
                .setIsSuccess(true)
                .setCode(code)
                .setMessage(message);
    }

    public static <T> Result genSuccessResult(String code, String message, T data) {
        return new Result()
                .setIsSuccess(true)
                .setCode(code)
                .setMessage(message)
                .setData(data);
    }

    public static Result genFailResult() {
        return new Result()
                .setIsSuccess(false)
                .setCode("-1")
                .setMessage("失败");
    }


    public static Result genFailResult(String code, String message) {
        return new Result()
                .setIsSuccess(false)
                .setCode(code)
                .setMessage(message);
    }

    public static <T> Result genFailResult(String code, String retMSg, T data) {
        return new Result()
                .setIsSuccess(false)
                .setCode(code)
                .setMessage(retMSg)
                .setData(data);
    }

}

三、RestRes响应数据格式化

import com.alibaba.fastjson.JSONObject;
import com.github.pagehelper.PageInfo;
import org.apache.commons.lang3.time.DateUtils;

import java.util.Date;

/**
 * 响应数据格式化
 * 只适用于名为soymilkadmin的前端项目
 *
 * @author yang
 * @create 2019-05-30
 */
public class RestRes {
    /**
     * @return com.alibaba.fastjson.JSONObject
     * @Description 返回格式化的表格数据
     * @Date 2019/5/30
     * @Param [list]
     **/
    public static JSONObject table(PageInfo pageInfo) {
        JSONObject jsonObject = new JSONObject();
        jsonObject.clear();
        jsonObject.put("content", pageInfo.getList());
        jsonObject.put("totalElements", pageInfo.getTotal());
        return jsonObject;
    }

    /**
     * @return com.alibaba.fastjson.JSONObject
     * @Description 返回
     * @Date 2019/5/30
     * @Param [list]
     **/
    public static <T> JSONObject token(String token, T user) {
        JSONObject jsonObject = new JSONObject();
        jsonObject.clear();
        jsonObject.put("token", token);
        jsonObject.put("user", user);
        return jsonObject;
    }

    /**
     * @return com.alibaba.fastjson.JSONObject
     * @Description
     * @Date 2019/5/30
     * @Param [list]
     **/
    public static <T> JSONObject appToken(String token, int expires_in) {
        JSONObject jsonObject = new JSONObject();
        jsonObject.clear();
        jsonObject.put("access_token", token);
        jsonObject.put("expires_in", expires_in);
        //token类型为app
        jsonObject.put("type", "A");
        return jsonObject;
    }

    public static <T> JSONObject clientToken(String token, int expires_in) {
        JSONObject jsonObject = new JSONObject();
        jsonObject.clear();
        jsonObject.put("token", token);
        long failtime = DateUtils.addSeconds(new Date(), expires_in).getTime();
        jsonObject.put("failtime", failtime);
        //token类型为client
        jsonObject.put("type", "client");
        return jsonObject;
    }

}


四、废话少说，看代码运用

/***
 * @Description 终端设备列表展示
 * @author Fu on 2019/10/22 0022 下午 1:19
 * @param  data  description
 * @return
 **/
@ApiOperation(value = "列表展示")
@GetMapping("/selectTerminals")
@ResponseBody
@IgnoreClientToken
@IgnoreUserToken
public Result selectTerminalList(@feign.Param("page") Integer page,
                                                      @feign.Param("size") Integer size,
                                                    @feign.Param("companyId") String companyId,
                                                    @feign.Param("asProductPricestrategyId")String asProductPricestrategyId){
    PageInfo pageInfo=service.selectTerminals(page,size,companyId,asProductPricestrategyId);
    return ResultGenerator.genSuccessResult(RestRes.table(pageInfo));
}

/**
 *  terminalid：
 * @return
 * @Description 插入/添加
 * @author Fu on 2019/10/15 0015 下午 6:14
 */
@ApiOperation(value = "插入")
@PostMapping("/insertTerminal")
@ResponseBody
public Result insertTerminal(@Param("terminalId") String terminalId,
                             @Param("coId") String coId,
                             @Param("name")String name,
                             @Param("phone")String phone){
    sysTerminalManagerService.insertTerminal(terminalId,name,phone,coId);
    return ResultGenerator.genSuccessResult();

}
