jsonp 已测试

1、js中
 $.ajax({
  type:'post',
dataType:'jsonp',
url:'http://localhost:8080/by/a/yzm?verifycode=1234'+'&phone=18788990099',
jsonp:'jsonpCallback',
success:function(data){
alert(data);


2、方法中
@RequestMapping(value = "/by/a/yzm")
@ResponseBody
public JSONPObject zym(Model model, HttpServletRequest request, HttpServletResponse response) {
Map<String, String> param = new HashMap<>();
String phone = request.getParameter("phone");
String verifycode = request.getParameter("verifycode");
param.put("phone", phone);
boolean check = true;
param.put("source", "");
param.put("validateCode", verifycode);
String url = Resources.getString("crm.service.url");
String resut = "processing ...";
if (resut.indexOf("processing") > 0) {
check = false;
}
return new JSONPObject(request.getParameter("jsonpCallback"),String.valueOf(check));
}
3、spring-dispatcher配置
<property name="defaultViews">
<list>
<bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />
</list>
</property>


注意 JSONPObject为import org.codehaus.jackson.map.util.JSONPObject;不要用错了
