p2p项目工具类

1.用于存放当前用户的上下文UserContext

package com.xmg.p2p.base.util;

import javax.servlet.http.HttpSession;

import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import com.xmg.p2p.base.domain.Logininfo;
import com.xmg.p2p.base.vo.VerifyCodeVO;

/**
 * 用于存放当前用户的上下文
 * @author Administrator
 *
 */
public class UserContext {
    public static final String USER_IN_SESSION = "logininfo";
    public static final String VERIFTCODE_IN_SESSION = "verifycode_in_session";
    /**
     * 方向获取request
     * @return
     */
    private static HttpSession getSesssion(){
        return ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest().getSession();
    }
    
    public static void putCurrent(Logininfo current){
        getSesssion().setAttribute(USER_IN_SESSION, current);;
    }
    public static Logininfo getCurrent(){
        
        return (Logininfo) getSesssion().getAttribute(USER_IN_SESSION);
    }
    
    
    
    /**
     * 用来得到设置自的短信验证码
     * @return
     */
    public static void putVerifyCode(VerifyCodeVO vc){
        getSesssion().setAttribute(VERIFTCODE_IN_SESSION, vc);
    }
    /**
     * 用来得到当前的短信验证码
     * @return
     */
    public static VerifyCodeVO getCurrentVerifyCode(){
        return (VerifyCodeVO) getSesssion().getAttribute(VERIFTCODE_IN_SESSION);
    }
}

2.返回结果类JSONResult

package com.xmg.p2p.base.util;
public class JSONResult {

    private boolean success = true ;
    private String msg;
    
    public JSONResult(boolean success, String msg) {
        super();
        this.success = success;
        this.msg = msg;
    }

    public JSONResult(String msg) { 
        super();
        this.msg = msg;
    }

    public JSONResult() {
        super();
    }

    public boolean isSuccess() {
        return success;
    }

    public void setSuccess(boolean success) {
        this.success = success;
    }

    public String getMsg() {
        return msg;
    }

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

3.时间工具类DateUtil

package com.xmg.p2p.base.util;

import java.util.Calendar;
import java.util.Date;

import org.apache.commons.lang.time.DateUtils;

public class DateUtil {

    
    /**
     * 用来计算发送两次验证码之间的间隔 () 
     * @param d1
     * @param d2
     * @return
     */
    public static long getBetweenSecond(Date d1 ,Date d2 ){
        return  Math.abs((d1.getTime() - d2.getTime())/1000) ;
    }
    /**
     * 得到一天的最后一秒钟
     * 
     */
    public static Date endOfDay(Date d) {
        return DateUtils.addSeconds(
                DateUtils.addDays(DateUtils.truncate(d, Calendar.DATE), 1), -1);
    }
    
    public static long secondsBetween(Date d1 , Date d2){
        return Math.abs(d1.getTime() - d2.getTime())/1000;//防止出现负数  用绝对值表示
    }
}

 4.系统中的常量BidConst

package com.xmg.p2p.base.util;

import java.math.BigDecimal;

/**
 * 系统中的常量
 * @author Administrator
 *
 */
public class BidConst {
    /**
     * 定义存储精度
     */
    public static final int STORE_SCALE = 4;
    /**
     * 定义运算精度
     */
    public static final int CAL_SCALE = 8;
    /**
     * 定义显示精度
     */
    public static final int DISPLAY_SCALE = 2;
    /**
     * 定义系统级别的0
     */
    public static final BigDecimal ZERO = new BigDecimal("0.0000"); 
    /**
     * 定义初始授信额度
     */
    public static final BigDecimal INIT_BORROW_LIMIT = new BigDecimal("5000.0000");
    
    /**
     * 默认管理员的用户名和密码
     * 
     */
    public static final String DEFAULT_ADMIN_NAME = "admin";
    public static final String DEFAULT_ADMIN_PASSWORD = "admin";
    
    /**
     * 手机验证码的有效期
     * 
     */
    public static final int VERIFYCODE_VAILDATE_SECOND = 300;
}

 5.用户状态类，记录用户在平台使用系统中所有的状态。BitStatesUtils

package com.xmg.p2p.base.util;

/**
 * 用户状态类，记录用户在平台使用系统中所有的状态。
 * 
 * @author Administrator
 */
public class BitStatesUtils {
    public final static Long OP_BIND_PHONE = 1L << 0; // 用户绑定手机状态码
    public final static Long OP_BIND_EMAIL = 1L << 1; // 用户绑定邮箱状态码
    public final static Long OP_BASIC_INFO = 1L << 2; // 用户填写基本资料
    public final static Long OP_REAL_AUTH = 1L << 3; // 用户是否已经实名认证
    public final static Long OP_VEDIO_AUTH = 1L << 4; // 用户是否已经视频认证
    public final static Long OP_HAS_BIDREQUEST_PROCESS = 1L << 5; // 用户是否已经有一个借款申请在申请流程中
    public final static Long OP_HAS_BIND_BANK = 1L << 6; // 用户是否已经绑定了银行卡
    public final static Long OP_HAS_WITHDRAW_PROCESS = 1L << 7; // 用户是否有提现在审核流程中

    /**
     * @param states
     *            所有状态值
     * @param value
     *            需要判断状态值
     * @return 是否存在
     */
    public static boolean hasState(long states, long value) {
        return (states & value) != 0;
    }

    /**
     * @param states
     *            已有状态值
     * @param value
     *            需要添加状态值
     * @return 新的状态值
     */
    public static long addState(long states, long value) {
        if (hasState(states, value)) {
            return states;
        }
        return (states | value);
    }

    /**
     * @param states
     *            已有状态值
     * @param value
     *            需要删除状态值
     * @return 新的状态值
     */
    public static long removeState(long states, long value) {
        if (!hasState(states, value)) {
            return states;
        }
        return states ^ value;
    }
}
