java - 将 httpservletrequest 传递给方法

Question

我有一个 servlet 类，它接受 HttpServletRequest，我需要将请求传递给另一个方法。我怎样才能用另一种方法获取请求。

Servlet:

     public void doPost(final HttpServletRequest request,
                               final HttpServletResponse response)
      XmlParser xmlParser = new XmlParser();
      xmlParser.getRequest(request);

XmlParser 类:

public class XmlParser{
    public void getRequest () //How can i get the request parameter from the servlet. 
    {
    }
}

Answer 1

将其传递给构造函数:

public class XmlParser{
    final private HttpServletRequest request;
    public XmlParser(HttpServletRequest request)
    {
        this.request = request;
    }
    // use it in othe methods...
}
