json - Convert java.util.Date to java.sql.Date with 'yyyy-mm-dd hh mm ss'

I need to pass json string to one of the rest web service. There is a property called 'amortizationdate' which will have format 'yyyy-mm-dd hh mm ss'.

for e.g. {amortizationdate:2015-07-31 00:00:00}

we are having AmortizationVO.java with a property amortizationdate.

for e.g

private java.sql.Date amortizationDate.


public void setAmortizationDate(java.sql.Date  date){

}

We need to set the date by calling setAmortizationDate(..date) method and using Jackson to convert AmortizationVO.java to Json.

but in JSON I m getting {amortizationdate:2015-07-31}. But expected result should be with timestamp.(amortizationdate:2015-07-31 00:00:00)

note: I don't want to use util date in my Value Object.

Pls help.

What I've tried:

java.util.Date utilDate = new java.util.Date();
java.sql.Timestamp sq = new java.sql.Timestamp(utilDate.getTime());


ExcelEntityAddressVO entityAddressVO = new ExcelEntityAddressVO();      

entityAddressVO.setAmortizationDate(new java.sql.Date(sq.getTime()));

This is my JSON:

{
  "amortizationdate" : "2015-07-31",
}
