Junit 数据类型匹配处理

1.date与字符串之间的互相转换

private String dateToString(String date) {
SimpleDateFormat formatDate = new SimpleDateFormat("yyyy-MM-dd");
String str = formatDate.format(date);
try {
time = formatDate.parse(str);
} catch (ParseException e) {
e.printStackTrace();
}
return formatDate.format(time);
}

public static Date StringToDate(String dateStr,String formatStr){
DateFormat sdf=new SimpleDateFormat(formatStr);
Date date=null;
try {
date = sdf.parse(dateStr);
} catch (ParseException e) {
e.printStackTrace();
}
return date;
}
Date date; public DategetDate() {String formatStr ="yyyy-mm-dd";DateFormat sdf =newSimpleDateFormat(formatStr);String dateStr=sdf.format(new Date());try {date=sdf.parse(dateStr);} catch(java.text.ParseException e) {e.printStackTrace();}return date;}

2.自己创建的entity类型的，new出一个，利用set方法赋值，可以用request.getsession().setAttribute("###",***)来传参
