请问如何只让在浏览器地栏输入http://local:8080/test/login_init.do有效,而屏蔽系统中其他的....x.do

Question

test是你的一个应用程序，还是一个应用程序中的子文件夹呀？？

Answer 1

如下是过滤器类：
package filters;import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletRequest;public class URLFilter implements Filter
{
    private FilterConfig config;
    protected final static String ALLOW_URI = "/test/login_init.do";
    public void init(FilterConfig config)
    {
        this.config = config;
    }
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)throws IOException,ServletException
    {
        HttpServletRequest httpRequest = (HttpServletRequest)request;
        HttpServletResponse httpResponse = (HttpServletResponse)response;
        String uri = httpRequest.getServletPath();
        if(uri.endsWith(".do"))
        {
            if(uri.equals(ALLOW_URI))
            {
                chain.doFilter(request, httpResponse);
                return;
            }
            httpResponse.setStatus(HttpServletResponse.SC_NOT_FOUND);//返回状态码404，未找到请求对象
        }
        chain.doFilter(request, httpResponse);
    }
    public void destroy()
    {
    }
}
在web.xml中再加入如下配置：
  <filter>
    <filter-name>URLFilter</filter-name>
    <description>only /test/login_init.do</description>
    <filter-class>filters.URLFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>GBK</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>URLFilter</filter-name>
    <url-pattern>/test/*</url-pattern>
  </filter-mapping>

Answer 2

test是我的一个应用程序根目录,我发现用以上的方法把所以.do都屏蔽了.是何原因

Answer 3

httpResponse.setStatus(HttpServletResponse.SC_NOT_FOUND);//返回状态码404，未找到请求对象
我不想返回状态码404，未找到请求对象
, 想让它返回到程序的入口(login_init.do).可以吗?

Answer 4

把httpResponse.setStatus(HttpServletResponse.SC_NOT_FOUND);改成：
response.sendRedirect("login_init.do")即可

Answer 5

既然test是应用程序，改正如下：
package filters;import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletRequest;public class URLFilter implements Filter
{
    private FilterConfig config;
    protected final static String ALLOW_URI = "/login_init.do";
    public void init(FilterConfig config)
    {
        this.config = config;
    }
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)throws IOException,ServletException
    {
        HttpServletRequest httpRequest = (HttpServletRequest)request;
        HttpServletResponse httpResponse = (HttpServletResponse)response;
        String uri = httpRequest.getServletPath();
        if(uri.endsWith(".do"))
        {
            if(uri.equals(ALLOW_URI))
            {
                chain.doFilter(request, httpResponse);
                return;
            }
            config.getServletContext().getNamedDispatcher("login_init.do").forward(request, response);////login_init.do为<servlet-name>
        }
        chain.doFilter(request, httpResponse);
    }
    public void destroy()
    {
    }
}
在web.xml中再加入如下配置：
  <filter>
    <filter-name>URLFilter</filter-name>
    <description>only /test/login_init.do</description>
    <filter-class>filters.URLFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>GBK</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>URLFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

Answer 6

不应该这么配置的，应该是：
  <filter>
    <filter-name>URLFilter</filter-name>
    <description>only /login_init.do</description>
    <filter-class>filters.URLFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>URLFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

Answer 7

这样处理,只有login_init.do可以,其它的不行,但正系统正常进入时,其它的也打不开.请指点.在线等.
谢谢
