枚举类型使用

 

枚举类型就是调用构造方法，向构造方法中传值，构造函数将枚举值赋值给属性，然后get即可。

调用构造方法的方式不是传统的new，而是直接点入枚举类型，枚举类型自动调用构造函数

 

 

 

 

 

ImgResp imgResp= new ImgResp();

Imginfo imginfo = new Imginfo();

imginfo.setImgUrl("bluckname="+imgInfoReq.getBluckname()+"&fName="+fileNameForm);

imginfo.setFileNameForm(fileNameForm);

imgResp.setResult(imginfo);

imgResp.setReturnCode(WeixinErrorMsg.SUCCESS.getCode());

imgResp.setReturnMsg(WeixinErrorMsg.SUCCESS.getText());

 

 

 

 

 

 

 

 

 

package com.itm.weixin.common;

 

import org.apache.commons.lang.StringUtils;

 

public enum WeixinErrorMsg {

 

SUCCESS("A0001","成功"),

 

PARAMETER_WRONG("A0001","参数不合法");

 

WeixinErrorMsg(String code,String text){

this.code = code;

this.text = text;

}

 

private String code;

 

private String text;

 

public String getCode() {

return code;

}

 

public void setCode(String code) {

this.code = code;

}

 

public String getText() {

return text;

}

 

public void setText(String text) {

this.text = text;

}

 

 

public static WeixinErrorMsg getByCode(String code){

if(StringUtils.isEmpty(code))

return null;

WeixinErrorMsg [] options = WeixinErrorMsg.values();

for (int i = 0; i < options.length; i++) {

if(options[i].getCode().equals(code)){

return options[i];

}

}

return null;

}

 

public static String getTextByCode(String code){

WeixinErrorMsg option = getByCode(code);

if(option == null)

return null;

return option.getText();

}

}
