Gente, boa noite. eu não sei se o problema está no eclipse ou no código.
o eclipse não está reconhecendo o filter que eu criei. O erro aparece no web.xml
segue o código abaixo
package filter;
import java.io.IOException;
import java.sql.Connection;
import java.sql.SQLException;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebFilter;
import connection.SingleConnection;
@WebFilter(urlPatterns={"/*"})
public class Filter implements javax.servlet.Filter {
@Override
public void destroy() {
}
private static Connection connection;
@Override
public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain arg2) throws IOException, ServletException {
try {
arg2.doFilter(arg0, arg1);
connection.commit();
} catch(Exception e) {
try {
connection.rollback();
} catch (SQLException e1) {
e1.printStackTrace();
}
}
}
@Override
public void init(FilterConfig arg0) throws ServletException {
connection = SingleConnection.getConnection();
}
}
