您好,我創建了一個過濾器類,並配置如下web.xml中:Java過濾器類的doFilter()沒有被調用
<filter>
<filter-name>LoginFilter</filter-name>
<filter-class>my.web.auth.LoginFilter</filter-class>
<init-param>
<param-name>test-param</param-name>
<param-value>This param is for testing</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>LoginFilter</filter-name>
<url-pattern>/html/test/*</url-pattern>
</filter-mapping>
當我訪問URL的http:// {} myJBoss /html/test/index.htm, LoginFilter的init()被調用,但不是的doFilter()
這裏是我的Filter類的摘錄:
public void init(FilterConfig config) throws ServletException {
log.debug("[201207bb] init"); //******This line can be seen in log file
this.config = config;
String testParam = config.getInitParameter("test-param");
log.debug("test-param="+testParam); //******* This is output correctly too
}
public void doFilter(ServletRequest req, ServletResponse res,
FilterChain chain) throws IOException, ServletException {
log.debug("[201207bb] doFilter"); //*****This line didn't appear in log file
HttpServletRequest request = (HttpServletRequest) req;
//Get the IP address of client machine.
String ipAddress = request.getRemoteAddr();
//Log the IP address and current timestamp.
log.debug("IP "+ipAddress + ", Time " + new Date().toString());
chain.doFilter(req, res);
}
有沒有人知道這是爲什麼? 我也試過jsp,結果也一樣。
你的意思是doFilter方法在服務器初始化時不被調用?什麼是你的jsp網址? – Jason 2012-07-20 02:56:46
是否有例外? – Raman 2012-07-20 03:20:30
夥計們,感謝您的回覆。 我只是意識到我已經設置了錯誤的url模式。 因爲我認爲當init()被調用意味着URL模式被擊中。但似乎並非如此。 – Bowie 2012-07-20 03:24:14
