Bom dia galera,
estou com um problema ao adicionar um filtro
já corri atras de alguma solução pelos forums e também no google
e não achei nada parecido, espero que alguem consiga me esclarecer porque estou travado
o que rola é o seguinte:
eu criei uma classe que implementa a superclasse Filter
package br.com.financeira.control;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.Enumeration;
import java.util.HashMap;
import java.util.Properties;
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.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import br.com.financeira.entity.Cliente;
public class SecurityFilter implements Filter {
@SuppressWarnings("rawtypes")
private HashMap resources = new HashMap();
@SuppressWarnings("unchecked")
public void init(FilterConfig config) throws ServletException{
try{
String accessFile = this.getClass()
.getClassLoader()
.getResource("properties/access.properties")
.getPath();
Properties properties = new Properties();
properties.load(new FileInputStream(accessFile));
resources.putAll(properties);
} catch(Exception e){
e.printStackTrace();
throw new ServletException(e);
}
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException{
boolean allowed = verifyAccess((HttpServletRequest) request);
if(!allowed){
String logon = "login.jsp?next=" + getNextURL((HttpServletRequest) request);
((HttpServletResponse) response).sendRedirect(logon);
}
chain.doFilter(request, response);
}
protected boolean verifyAccess(HttpServletRequest request) {
String resource = request.getRequestURI().replaceAll(request.getContextPath(), "");
while (resource.length() > 0){
String rules = (String) resources.get(resource);
if (rules != null){
try{
Cliente user = (Cliente) request.getSession().getAttribute(Cliente.KEY);
return (user.getIdCliente() != 0);
}catch(NullPointerException npe){return false;}
catch(Exception e){return false;}
} else if (!resource.equals("/")) {
int index = resource.lastIndexOf("/");
if (index > -1) {
resource = resource.substring(0, index);
}
} else {
resource = "";
}
}
return true;
}
protected String getNextURL(HttpServletRequest request){
String url = request.getRequestURI();
StringBuffer params = new StringBuffer("");
Enumeration<?> enumParams = request.getParameterNames();
while (enumParams.hasMoreElements()){
String name = (String) enumParams.nextElement();
String value = request.getParameter(name);
if (params.length() > 0){
params.append("&");
}
params.append(name).append("=").append(value);
}
return url + "?" + params.toString();
}
public void destroy() {
// TODO Auto-generated method stub
}
}acontece que ao adicioná-la no web.xml ela dá pau (obs.: já tentei mudar a versão do xml para 2.5 e também não funciona)
segue meu web.xml
[code]<?xml version="1.0" encoding="UTF-8"?>
… (Resto do xml com os servlets)
então ao rodar o sistema acontece o problema
ele não consegue subir o projeto
“ERRO 404”
e envia a seguinte mensagem no console
GRAVE: End event threw exception
