My target is to generate such json string: {"EndTime": "\/Date(1309737600000)\/"}
I define a HashMap to generate the string
If I define the string value as "\\/Date(1317375052044)\\/" then the result is "\\\\/Date(1317375052044)\\\\/".
If I define the string as "/Date(1317375052044)/" then the result is "/Date(1317375052044)/".
How I can generate the result "\/Date(1309737600000)\/"?
