<p>Yes, use a framework. Servlets and JPS alone are like water and stones - you can build road with them, but you can't request them to do it alone. You have to sweat, or get some framework to do it for you ;)</p>

<p>I suggest <a href="http://www.playframework.org/" rel="nofollow">http://www.playframework.org/</a> (1.2.4 ... 2.0 is less Javish, more Scalish-like) if you are familiar with Java</p>


blocks|key|1474511|text|是的，您可以在servlet中添加html代码，然后将重定向发送到JSP页面。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1474512|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

<p>Yes,in the servlet you can add the html code,and then send a redirect to the JSP page.</p>


blocks|key|969869|text|我想你想要的是一个前锋。浏览器URL将维护servlet的URL，放在请求上的属性将可用于jsp。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|969870|RequestDispatcher+r=+getServletContext().getRequestDispatcher("foo.jsp")；|969871|R.forward(请求，响应)；|969872|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

<p>I think what you want is a forward. The browser URL will maintain the URL of the servlet and attributes put on the request will be available to the jsp. </p>

<p>RequestDispatcher r = getServletContext().getRequestDispatcher("foo.jsp");</p>

<p>r.forward(request, response);</p>


blocks|key|5516042|text|只需调用servlet的URL而不是JSP的URL，并在servlet的doGet()方法中执行预处理工作。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|5516043|例如，一个servlet，它在JSP呈现产品之前加载产品列表：|5516044|@WebServlet("/products")

}|code-block|syntax|javascript|5516045|其中JSP如下所示：|5516046|<%25@+taglib+uri="http://java.sun.com/jsp/jstl/core"+prefix="c"+%25>

</html>|5516047|如果您直接转到http://localhost:8080/contextname/products，那么servlet的doGet()将被调用，产品将从DB加载并存储在请求作用域中，控制权将被转发给JSP，后者反过来以一些漂亮的HTML标记显示结果。|5516048|另请参阅：|5516049|5516050|Our+Servlets+wiki+page|unordered-list-item|5516051|5516052|entityMap|0|LINK|mutability|MUTABLE|url|http://localhost:8080/contextname/products|1|https://stackoverflow.com/tags/servlets/info^0|10|7|0|0|0|0|0|1O|7|7|16|0|0|0|0|0|M|1|0|0^^$0|@$1|2|3|4|5|6|7|19|8|@$9|1A|A|1B|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|1C|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|1D|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|1E|8|@]|D|@]|E|$]]|$1|O|3|P|5|J|7|1F|8|@]|D|@]|E|$K|L]]|$1|Q|3|R|5|6|7|1G|8|@$9|1H|A|1I|B|C]]|D|@$9|1J|A|1K|1|1L]]|E|$]]|$1|S|3|T|5|6|7|1M|8|@]|D|@]|E|$]]|$1|U|3|-4|5|6|7|1N|8|@]|D|@]|E|$]]|$1|V|3|W|5|X|7|1O|8|@]|D|@$9|1P|A|1Q|1|1R]]|E|$]]|$1|Y|3|-4|5|6|7|1S|8|@]|D|@]|E|$]]|$1|Z|3|-4|5|6|7|1T|8|@]|D|@]|E|$]]]|10|$11|$5|12|13|14|E|$15|16]]|17|$5|12|13|14|E|$15|18]]]]

<p>Just invoke the URL of the servlet instead of the URL of the JSP and do the preprocessing job in the <code>doGet()</code> method of the servlet.</p>

<p>E.g. a servlet which loads a list of products before the JSP presents them:</p>

<pre><code>@WebServlet("/products")
public class ProductServlet extends HttpServlet {

    @EJB
    private ProductService productService;

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // Preprocess request: load list of products for display in JSP.
        List&lt;Product&gt; products = productService.list();
        request.setAttribute("products", products);
        request.getRequestDispatcher("/WEB-INF/products.jsp").forward(request, response);
    }

}
</code></pre>

<p>Where the JSP look like this:</p>

<pre class="lang-html prettyprint-override"><code>&lt;%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %&gt;
&lt;%@ taglib uri="http://java.sun.com/jsp/jstl/format" prefix="fmt" %&gt;

&lt;!DOCTYPE html&gt;
&lt;html lang="en"&gt;
    &lt;head&gt;
        &lt;title&gt;Our Products&lt;/title&gt;
    &lt;/head&gt;
    &lt;body&gt;
        &lt;h1&gt;Products&lt;/h1&gt;
        &lt;table&gt;
            &lt;tr&gt;
                &lt;th&gt;ID&lt;/th&gt;
                &lt;th&gt;Name&lt;/th&gt;
                &lt;th&gt;Description&lt;/th&gt;
                &lt;th&gt;Price&lt;/th&gt;
            &lt;/tr&gt;
            &lt;c:forEach items="${products}" var="product"&gt;
                &lt;tr&gt;
                    &lt;td&gt;${product.id}&lt;/td&gt;
                    &lt;td&gt;&lt;c:out value="${product.name}" /&gt;&lt;/td&gt;
                    &lt;td&gt;&lt;c:out value="${product.description}" /&gt;&lt;/td&gt;
                    &lt;td&gt;&lt;fmt:formatNumber value="${product.price}" type="currency" /&gt;&lt;/td&gt;
                &lt;/tr&gt;
            &lt;/c:forEach&gt;
       &lt;/table&gt;
    &lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>If you go to <a href="http://localhost:8080/contextname/products" rel="nofollow noreferrer">http://localhost:8080/contextname/products</a> directly, then the servlet's <code>doGet()</code> will be invoked and the products will be loaded from the DB and stored in the request scope and the control will be forwarded to the JSP which in turn presents the results in some pretty HTML markup.</p>

有没有一种方法可以在不使用物理url链接的情况下将servlet链接到JSP。所以我希望servlet运行，然后servlet将我带到JSP。任何想法。
