工具类

工具类：

1. Result

package com.test.user.common;


public class Result {

    private final static String SUCCESS_CODE = "200";
    private final static String ERROR_CODE = "400";

    private String code;
    private Object data;
    private String msg;

    private Result() {
    }

    public static Result success() {
        return new Result().setCode(SUCCESS_CODE);
    }

    public static Result success(Object object) {
        return new Result().setCode(SUCCESS_CODE).setData(object);
    }

    public static Result error(String msg) {
        return new Result().setMsg(msg).setCode(ERROR_CODE);
    }

    public String getCode() {
        return code;
    }

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

    public Object getData() {
        return data;
    }

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

    public String getMsg() {
        return msg;
    }

    public Result setMsg(String msg) {
        this.msg = msg;
        return this;
    }

}

2. BlankUtil

package com.test.util;

import java.util.List;
import java.util.Map;

public abstract class BlankUtil {

	private BlankUtil(){
	}

	public static boolean IsBlank(Object obj){

		if(obj == null)
			return true;

		if(obj instanceof List)
			if(((List)obj).size()==0)
				return true;

		if(obj instanceof Map)
			if(((Map)obj).size()==0)
				return true;

		if(obj instanceof String)
			if(((String)obj).trim().length()==0)
				return true;
		return false;
	}

	public static boolean IsNotBlank(Object obj){
		return !IsBlank(obj);
	}
