renderURL可以通过 mvcPath来配置跳转。但是actionURL无效。想要实现后台方法执行完成后跳转 需要在后台方法的最后加入代码

actionResponse.setRenderParameter("jspPage","/html/userinfomanageraction/updateemail/new_email.jsp");

第二个参数为jsp文件的路径。这样既可实现mvcPortlet的actionURL执行完后台方法后的跳转

如果没有配置<action-url-redirect>true</action-url-redirect>

也可以这么写

ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest.getAttribute(WebKeys.THEME_DISPLAY);
String portletName = (String)actionRequest.getAttribute(WebKeys.PORTLET_ID);
PortletURL redirectURL = PortletURLFactoryUtil.create(PortalUtil.getHttpServletRequest(actionRequest), portletName,
themeDisplay.getLayout().getPlid(), PortletRequest.RENDER_PHASE);

redirectURL.setParameter("view", "abc");

actionResponse.sendRedirect(redirectURL.toString());
