前后端分离RequestResult返回模型的封装

前后端分离RequestResult返回模型的封装

封装代码

public class RequestResult {

    private String code;

    private String message;

    private Object data;

    public RequestResult() {}

    public RequestResult (String code, String message) {
        this.code = code;
        this.message = message;
    }

    public RequestResult (String code, String message, Object data) {
        this.code = code;
        this.message = message;
        this.data = data;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public Object getData() {
        return data;
    }

    public void setData(Object data) {
        this.data = data;
    }
}

使用实例

    @RequestMapping("/face/getverifycode")
    @ResponseBody
    public Object getVerifyCode() {
        RequestResult requestResult = new RequestResult();
      	requestResult.setCode(ResultTypeEnum.ResultTypeEnum_200.getCode());
        requestResult.setMessage(ResultTypeEnum.ResultTypeEnum_200.getMessage());

        try {
           // 你的逻辑
        } catch (Exception e) {
            // 在枚举中定义好返回的code和message
            requestResult.setCode(ResultTypeEnum.ResultTypeEnum_1001.getCode());
            requestResult.setMessage(ResultTypeEnum.ResultTypeEnum_1001.getMessage());
        } finally {
            // 必须要处理的
        }
        return requestResult;
    }

枚举封装

import org.apache.commons.lang3.StringUtils;

public enum ResultTypeEnum {
	// 维护枚举值和错误信息，避免在代码中存在魔法值
    ResultTypeEnum_200("200", "成功"),
    ResultTypeEnum_1001("1001", "内部错误");

    private String code;
    private String desc;

    ResultTypeEnum(String code, String desc) {
        this.code = code;
        this.desc = desc;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getDesc() {
        return desc;
    }

    public void setDesc(String desc) {
        this.desc = desc;
    }

    public static Boolean isFailed(String code){
        return !isSuccess(code);
    }

    public static Boolean isSuccess(String code){
        return StringUtils.equals(ResultTypeEnum.ResultTypeEnum_200.getCode(), code);
    }
}
