Get full request path from HttpServletRequest

String url =  request.getRequestURI();  // This method can only get the request url that does not contain parameters, and only contains relative paths

StringBuffer url_buffer = request.getRequestURL(); // This method can only get the request url without parameters, but the absolute path

String queryString = request.getQueryString(); ;// This method can get the parameter string after the url

Combining them can get the complete request path, which is explained by the program below:

Enter in the address bar: http://localhost:8080/rtsbiz/page/goto.do?view=/page/jsp/maintainence/meeting/index, press Enter

The servlet program responsible for the response is as follows:

        String url = request.getRequestURI(); // This method can only get the request url that does not contain parameters, and only contains the relative path 
        System.out.println("url="+ url);
        StringBuffer url_buffer = request.getRequestURL(); // This method can only get the request url without parameters, but the absolute path 
        System.out.println("url_buffer="+ url_buffer.toString());
        String queryString = request.getQueryString();; // This method can get the parameter string after the url 
        System.out.println("queryString="+queryString);

The output is as follows:

url=/rtsbiz/page/goto.do
url_buffer=http://localhost:8080/rtsbiz/page/goto.do
queryString=view=/page/jsp/maintainence/meeting/index
