jquery ajax spring mvc

ajax 2种提交方式

   get

$.ajax({     
	        type: "Get",     
	        url: "/xiangmu/user/preparPayWeixin/result/"+out_trade_no+".action",      
	        success: function(data) {
	        	if(data.xxx== 'success'){
		            //具体业务
	        	}
	        },     
	        error: function(err) {     
	        	
	        }
	    });

   post

$.ajax({
            type: "POST",
            url: "Service/SimpleData",
            contentType: "application/json", //必须有
            dataType: "json", //表示返回值类型，不必须
            data: JSON.stringify({ 'foo': 'foovalue', 'bar': 'barvalue' }),  //data: "{'str1':'foovalue', 'str2':'barvalue'}",
            success: function (jsonResult) {
                alert(jsonResult);
          

 

 

对应的2种spring mvc

   对应get方式的

@Controller
@RequestMapping("/user/preparPayWeixin")
public class PreparPayNotifyWeixinController extends BaseController{
		
	@ResponseBody
	@RequestMapping(value="result/{sn}",produces = "text/html;charset=UTF-8",method = {RequestMethod.POST, RequestMethod.GET})
	public String getResult(@PathVariable("sn") String sn){
		String re = "";
		if(payStatus.get(sn) != null && "success".endsWith(payStatus.get(sn))){
			re = "{\"data\":\"success\"}";
		}else{
			re = "{\"data\":\"fail\"}";
		}

		return re;
	}

   说明：@ResponseBody：返回给ajax的json数据用此注解

              result/{sn}：{sn}为路径参数，需要和@PathVariable("sn")一起使用

     method = {RequestMethod.POST, RequestMethod.GET}：接收get和post方式

     produces = "text/html;charset=UTF-8"：匹配请求头，Accept：text/html，不常使用

             spring mvc还有一个常用注解：@RequestParam(value="aa", required=true)String title

 

 对应post方式的mvc

 

@RequestMapping(value = "/SimpleData",method=RequestMethod.POST)
@ResponseBody
public ActionResult SimpleData(string foo, string bar){            
    return Json("SimpleData", JsonRequestBehavior.AllowGet);
}
