如何快速解决JS或Jquery ajax异步跨域的问题

$.ajax({ 
   url :'http://localhost:8080/myProject/test' 
    type : "GET",//不局限于get 
   data:{"key1":value1,"key2":value2}, 
   async : true, 
   suess : function(data) { 
    var dataObj=eval("("+data+")"); 
     console.log(dataObj); 
     
   }, 
   error : function(data) { 
    alert( "服务器连接失败 ajaxJsonp" ); 
   } 
  }); 

response.setHeader("Aess-Control-Allow-Origin", "");//设置可跨域资源共享的域名，只能设置一个具体的域名，但可以代表所有 
response.setHeader("Aess-Control-Allow-Methods","GET,POST,PUT,OPTIONS");//设置可跨域资源共享的请求方式 
  response.setHeader("Aess-Control-Allow-Credentials","true"); 
  response.setHeader("Aess-Control-Allow-Headers" ,"Origin, X-Requested-With, Content-Type, Aept");
