spring入口配置(web.xml):

		<!-- it's just for springDispatcher -->

	<servlet-mapping>

	</servlet-mapping>

其他域名的项目请求:
@H_450_17@<!DOCTYPE html> <html> <head> <Meta charset="UTF-8"> <title>APP-JSONP-CALL</title> <script type="text/javascript" src="js/jquery-2.1.4.js"></script> <script type="text/javascript" src="http://localhost/js/test.js"></script> <script type="text/javascript"> /* function jsonp(s) { alert(s); } */ //alert("jsonp no"); /*不要想无参数@L_618_11@函数传送参数,否则,@L_618_11@报错!*/ $.ajax({ dataType : "JSONP",jsonp : "callBACk",//请求自动带上callBACk参数，callBACk值为jsonpCallBACk的值 jsonpCallBACk : "test1",//接口服务器应该返回字符串数据格式：login(JSON数据) type : "POST",url : "http://www.xiuye.com/josnp.do",//接口服务器地址 data : { /* user : "xiuye" */ },//请求数据 success : function(responsE) { //成功执行 console.log(responsE); //alert("jsonp OK"); },error : function(E) { //失败执行 alert(e.status + ',' + e.statusText); } }); //alert("jsonp have"); $.ajax({ dataType : "JSONP",//请求自动带上callBACk参数，callBACk值为jsonpCallBACk的值 jsonpCallBACk : "test2",//接口服务器地址 data : { user : "xiuye",password : "123456",obj : [ { kk : "eee",ll : "dsdf" },{ kk : "123",ll : "56" } ] },' + e.statusText); } }); $.ajax({ dataType : "JSONP",//请求自动带上callBACk参数，callBACk值为jsonpCallBACk的值 jsonpCallBACk : "test3",//接口服务器地址 /* data : { },//请求数据 */ success : function(responsE) { //成功执行 console.log(responsE); alert("jsonp test3 := " + responsE); },' + e.statusText); } }); </script> </head> <body> </body> </html>

注:1.请求的参数个数和方法名必须与@L_618_11@一致,否则报错.

2.@L_618_11@接收的参数在Map<String,String[]>中,如有参数只需在mapper类中方法上只能写Map<String,String[]>形参得到,请求参数!

3.限制大(不太灵活方便),也许有隐藏的bug,仅作为练习.
