Obtain the method name, parameters, path and other information according to the front-end request
// If you want to get the request information in a method, you need to get the request from the request context, or use HttpServletRequest request in the parameter list
① Get the request context in the method
// Receive the request and record the request content
ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes ();
② Get request
//接收到request
HttpServletRequest request = attributes.getRequest();
③ Get parameters
Map<String,Object> map = getParameterMap(request);
System.out.println("我是从Map参数获取的："+Arrays.asList(map));
Focus: getParameterMap method
/**
* 获取所有请求参数，封装为map对象
*
* @return
*/
public Map<String, Object> getParameterMap(HttpServletRequest request) {
if (request == null) {
return null;
}
Enumeration<String> enumeration = request.getParameterNames();
Map<String, Object> parameterMap = new HashMap<String, Object>();
StringBuilder stringBuilder = new StringBuilder();
while (enumeration.hasMoreElements()) {
String key = enumeration.nextElement();
String value = request.getParameter(key);
String keyValue = key + " : " + value + " ; ";
stringBuilder.append(keyValue);
parameterMap.put(key, value);
}
return parameterMap;
}
So you can get all the information
