这是回调方法
}
@RequestMapping("/xcxNotify")
@PostMapping(value = "pay",produces = "application/xml")//声明返回结果为xml类型
public Map<String,String> hello(@RequestBody Map<String,String> result){//在pom文件中引入了xml解析器
System.err.println("[订单服务] 接收微信支付回调");
Map<String,String> msg = new HashMap<>();
msg.put("return_code", "SUCCESS");
msg.put("return_msg", "OK");
return msg;
}下面是异常

看错误是json解析异常，你看下官方文档，有demo的
微信的回调是一个 xml 格式的，是没有办法直接转成 map 的，至少通过 json 的工具不行。你要获取到原始内容，然后通过其他的方式解析这个 xml。然后再提取你想要的信息。
//回调接口
@RequestMapping("/payNotify")
@ResponseBody
public void payNotify(HttpServletRequest request, HttpServletResponse response) {
String res = "";
try {
Map<String, String> map =getPostXmlData(request);
} catch (Exception e) {
e.printStackTrace();
res = "<xml><return_code><![CDATA[FAIL]]></return_code><return_msg><![CDATA[ERROR]]></return_msg></xml>";
} finally {
try {
response.getWriter().write(res);
} catch (IOException e) {
e.printStackTrace();
}
}
}
//工具方法
public Map<String, String> getPostXmlData(HttpServletRequest request) throws BussinessException {
String xmlData = null;
ServletInputStream sis = null;
Map<String, String> resMap = new HashMap();
try {
// 取HTTP请求流
sis = request.getInputStream();
// 取HTTP请求流长度
int size = request.getContentLength();
// 用于缓存每次读取的数据
byte[] buffer = new byte[size];
// 用于存放结果的数组
byte[] xmldataByte = new byte[size];
int count = 0;
int rbyte = 0;
// 循环读取
while (count < size) {
// 每次实际读取长度存于rbyte中
rbyte = sis.read(buffer);
for (int i = 0; i < rbyte; i++) {
xmldataByte[count + i] = buffer[i];
}
count += rbyte;
}
xmlData = new String(xmldataByte, "UTF-8");
resMap = WxPayV3Util.readStringXmlOut(xmlData);
} catch (IOException e) {
logger.error("文件流异常", e);
} catch (Exception e) {
logger.error("系统异常", e);
} finally {
if (sis != null) {
try {
sis.close();
} catch (IOException e) {
logger.error("文件流异常", e);
}
}
}
return resMap;
}
