Thanks。but my code is 

atlassian-plugin.xml 

<servlet-filter name="permitServlet" key="dsdFilter" class="web.filter.lmFilter" system="true" weight="100">
    <description>this is the first filter </description>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
</servlet-filter> 

@Override
public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws IOException, ServletException {
    HttpServletRequest request=(HttpServletRequest)req;
    HttpServletResponse response=(HttpServletResponse) resp;
    ApplicationUser loggedInUser = jiraAuthenticationContext.getLoggedInUser();
    if (null == loggedInUser) {
        String url = request.getContextPath()+"/login.jsp?permissionViolation=true&os_destination="+request.getRequestURI();
        StringBuffer stringBuffer = new StringBuffer();
        String fullUrl =(stringBuffer.append(url).append("?").append(request.getQueryString())).toString();
       response.sendRedirect(fullUrl);
} 

I don't know where the mistake is. 

Thanks again. (-_-)
