有時(shí)候我們jsp需要展示的頁(yè)面是從數(shù)據(jù)庫(kù)里動(dòng)態(tài)引入的
所以需要先鏈接到一個(gè)servlet，再跳轉(zhuǎn)到j(luò)sp頁(yè)面
那么要怎么做呢
首先使用jsp的動(dòng)態(tài)引入
<jsp:include page="/bookshow"></jsp:include>
url的鏈接就是servlet的鏈接
然后在servlet中獲取數(shù)據(jù)中使用req的跳轉(zhuǎn)
protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
req.setCharacterEncoding("utf-8");
resp.setContentType("text/html;charset=utf-8");
BookService bs = new BookServiceImpl();
List<Book> lb = bs.ShowAllBooks();
req.setAttribute("books",lb);
req.getRequestDispatcher("FontMain/bookright.jsp").include(req,resp);
}
注意是include不是reforword
最后顯示的bookright頁(yè)面就是我們所要的頁(yè)面了
