[英]how to put the object to Java servlet response?
In a Java servlet, how might I put the object to servlet response? 在Java servlet中,我如何将对象放到servlet响应中? In the code below, the name is shown on the page.
在下面的代码中,名称显示在页面上。
servlet:
private void process(HttpServletRequest request, HttpServletResponse response) throws Exception{
String name = "John";
System.out.println("main servlet");
request.setAttribute("name", name);
response.sendRedirect("index.jsp");
}
index.jsp in JSTL
<body>
name: ${requestScope.name}
</body>
Replace response.sendRedirect(...)
with: 将
response.sendRedirect(...)
替换为:
RequestDispatcher rd = request.getRequestDispatcher("index.jsp");
rd.forward(request, response);
