}
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws ServletException, IOException {
HttpServletRequest req = (HttpServletRequest) servletRequest;
servletRequest.setCharacterEncoding(“UTF-8″);
HttpServletResponse res = (HttpServletResponse) servletResponse;
String url = req.getRequestURI();
SysUserVOImpl user = (SysUserVOImpl) req.getSession().getAttribute(“SysUser”);
if (null == user) {
if (!COMMON.isEmpty(url) && (url.endsWith(“newestlogin.jsp”) || url.endsWith(“UserLoginAction.jsp”) || url.endsWith(“login.jsp”) || url.endsWith(“loginAction.do”))) {
filterChain.doFilter(servletRequest, servletResponse);
} else {
req.getRequestDispatcher(“/newestlogin.jsp”).forward(req, res);
}
} else {
filterChain.doFilter(servletRequest, servletResponse);
}
}
