我正在尝试使用ajax调用在我的程序中获取list of countries，如下所示
这是我的ajax电话
function countryList(){
var url = contextPath+"/master/country";
$.ajax({
url : url,
type:"get",
contentType:'application/json; charset=utf-8',
dataType: 'json' ,
async: false,
success:function(response)
{
console.log(response);
alert(response);
var slno=0;
for(var i=0;i<response.data.length;i++)
{
slno++;
$('#countryTable').append("<tr><td>"+slno+"</td><td>"+response.data[i].countryName+"</td><td><i class='fas fa-eye fa-2x eye countryEye'><input type='hidden' value='"+response.data[i].countryId+"'></td></tr>")
}
$('#countryTable').DataTable();
}
});
}
这是我的实体类

ajax get call进入控制器和每一层list of countries also getting from database，但响应没有进入ajax调用
给出以下错误
GET http://localhost:8015/campasAdmin/master/country 500 (Internal Server Error)
请帮帮我
