前端：

var dataArray = []//一個數組

$.ajax({

type: "POST",
traditional: true,
contentType:'application/json;charset=UTF-8',
dataType: 'json',
url: url,
data: JSON.stringify({listKey:dataArray}),
success: function(response) {

}

})

後臺

@responseBody

@requestMapping("/test")

private String Test(@requestBody Form, HttpServletRequest request){

//..............

}

class Form{

private List<B> listKey;

//get

//set

}
