java web指定主页

正常情况下主页是在web.xml里面配置欢迎页面，可以加个过滤器重定向就可以：

public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {

        HttpServletRequest request = (HttpServletRequest) req;

        HttpServletResponse response = (HttpServletResponse) res;

        String effectivePath = request.getRequestURI().substring(request.getContextPath().length());

        if (effectivePath.equals("/")) {

                //访问项目的根路径

            response.sendRedirect("/destination.jsp");

            return;

        }

        chain.doFilter(request, response);

    }
