java中如何实现伪静态

在Java中实现伪静态通常涉及到将动态URL转换为静态URL，这样可以提高搜索引擎的友好性，同时也可以提高用户体验。以下是在Java中实现伪静态的几种常见方法：

1. 使用Servlet过滤器

通过编写一个Servlet过滤器，可以拦截动态请求，并将其转换为静态URL。

```java

public class RewriteFilter implements Filter {

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

HttpServletRequest httpRequest = (HttpServletRequest) request;

HttpServletResponse httpResponse = (HttpServletResponse) response;

String pathInfo = httpRequest.getPathInfo();

if (pathInfo != null && pathInfo.startsWith("/dynamic/")) {

String newPathInfo = pathInfo.replace("/dynamic/", "/static/");

httpRequest.setAttribute("pathInfo", newPathInfo);

httpRequest.getRequestDispatcher(newPathInfo).forward(request, response);
