枚举的使用，使项目变得高大上

package com.example.demo.config;

public enum StatusEnum {
    SU("success",3),
    FA("Fail",4);

    private String status;
    private int code;

    private StatusEnum(String status, int code) {
        this.status = status;
        this.code = code;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public int getCode() {
        return code;
    }

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

    public  static int getByStatus(String msg){
        for (StatusEnum statusEnum:StatusEnum.values()){
            if (statusEnum.getStatus().equals(msg)){
                return  statusEnum.getCode();
            }
        }
        return 0;

            }
        }
        return null;
