登录过滤器的问题
在WEB.XML中配置好了,没有任何问题,以下是代码
<filter>
<filter-name>checkLogon</filter-name>
<filter-class> desoft.util.CheckLogon</filter-class>
</filter>
<filter-mapping>
<filter-name>checkLogon</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter>
<filter-name>CharactorEncocedingFilter</filter-name>
<filter-class>
desoft.util.CharactorEncocedingFilter
</filter-class>
<init-param>
encoding
UTF-8
</init-param>
</filter>
但是在.JAVA文件中老师说少了个参数,每次SESSION 结束后,在刷新时,登陆界面就只会出现在 mainFrame中,才用的是 3栏式的FRAME结构,请高手看看少 了个什么参数,以下是过滤类源代码:
public class CheckLogon implements Filter {
protected FilterConfig filterConfig;
public void destroy() {
lterConfig=null;
}
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse,
FilterChain filterChain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest)servletRequest;
HttpServletResponse response = (HttpServletResponse)servletResponse;
UserinformationVO uservo = (UserinformationVO) tSession().getAttribute("users");
intln(uservo);
boolean requestLoginAction=false;
if( tRequestURI().endsWith(" ")){
String query = tQueryString();
if( dexOf(" ")!=-1){
requestLoginAction=true;
}
}
if( tRequestURI().endsWith(" ml")|| tRequestURI().endsWith("adminlogin.jsp")|| tRequestURI().endsWith(".gif")|| tRequestURI().endsWith(".jpg")||requestLoginAction){
Filter(servletRequest, servletResponse);
return;
}
if(uservo==null){
intln("uservo==null");
ndRedirect( tContextPath()+"/ ml");
return ;
}
Filter(servletRequest, servletResponse);
}
public void init(FilterConfig config) throws ServletException {
lterConfig = config;
intln("Check Logon is initing.......");
}
}
