我使用的是spring MVC框架,测试的控制器代码如下:
package com.web.controller; import java.util.HashMap;
import java.util.Map; import javax.servlet.http.HttpServletRequest; import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody; import com.common.util.SystemHWUtil;
import com.common.util.WebServletUtil;
import com.string.widget.util.ValueWidget;
import com.util.JSONPUtil;
/***
* 用于测试跨域
* @author huangweii

*/
@Controller
@RequestMapping("/cors")
public class CORSController {
@ResponseBody
@RequestMapping(value = "/simple",produces=SystemHWUtil.RESPONSE_CONTENTTYPE_JSON_UTF)
public String corsJsonSimple(HttpServletRequest request,String callback){
String content;
Map map=new HashMap();
map.put("username", "黄威");
map.put("age", "27");
map.put("address", "beijing");
content=JSONPUtil.getJsonP(map, callback);
System.out.println("getIpAddr:"+WebServletUtil.getIpAddr(request));
System.out.println("getRemoteAddr:"+WebServletUtil.getRemoteAddr(request));
System.out.println("getClientIpAddr:"+WebServletUtil.getClientIpAddr(request));
System.out.println("getClientIpAddress:"+WebServletUtil.getClientIpAddress(request));
return content;
} }
测试结果:
