Can any one let me know what is wrong in my code?

Answer 1

As far as I understand, your created json is
{
"ID": "012",
"Name": "this is a"
}
but it requires
{
"Shop":[
{
"ID": "001",
"Name": "ABC"
},
{
"ID": "002",
"Name": "XYZ"
}
]
}
So you need to change the object of post body. My quick fix for this case is
Map<String, Object> item = new HashMap<>();
item.put("Name", "this is a");
item.put("ID", "012");
JSONObject shop = new JSONObject();
shop.put("shop", Collections.singleton(item));
given().log().all()
.contentType(ContentType.JSON)
.body(shop.toJSONString()).
.when()
.post("your-url")
.then()
.statusCode(201)
.log().ifError();
