Aspectj：獲取來自HttpServletRresponse的響應正文（HTML文本）

Question

我嘗試使用aspectJ攔截HttpServlet.do *（request，response）並獲取HTML文本（需要提取標題並將html存儲到文件中）。

一旦我有了對HttpServletResponse的引用，訪問響應正文（html文本）的最佳方式是什麼？

這是我的凝視代碼。

public aspect HttpRequestHandlerAspect { 

pointcut getRequest(HttpServletRequest request, HttpServletResponse response) 
    : execution(protected * javax.servlet.http.HttpServlet.*(HttpServletRequest, HttpServletResponse)) 
    && args(request, response); 

    Object around(HttpServletRequest request, HttpServletResponse response) : getRequest(request, response) { 
     Object ret = proceed(request, response); 
       // now how do I access the HTML response text (and get the title of the page) in here? 

    } 
} 

Answer 1

這可能不是你的問題的確切的答案，但嘗試提取響應，這裏建議：How can I read an HttpServletReponses output stream? 您不必創建一個過濾器，只有一個HttpServletResponseWrapper它傳遞給

繼續（請求，包裝）。

Object around(HttpServletRequest request, HttpServletResponse response): getRequest(request, response) { 
    MyHttpServletResponseWrapper wrapper = new MyHttpServletResponseWrapper(response); 
    Object ret = proceed(request, wrapper); 
    // The MyHttpServletReponseWrapper class captures everything and doesn't forward to the original stream, so we have to do this 
    response.getWriter().write(wrapper.toString()); 
    // use wrapper.toString() to access response 
}
