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;
}
}
