**Filter代码**

**AFilter**

package com.wang.sb.filter;
    import javax.servlet.*;
    import java.io.IOException;

        }
    
        @Override
        public void destroy() {
    
        }
    }

** BFilter**

package com.wang.sb.filter;
    
    import javax.servlet.*;
    import java.io.IOException;

        }
    
        @Override
        public void destroy() {
    
        }
    }

** CFilter**

package com.wang.sb.filter;
    
    import javax.servlet.*;
    import java.io.IOException;
    
    /**

        }
    
        @Override
        public void destroy() {
    
        }
    }

** DFilter**

package com.wang.sb.filter;
    
    import javax.servlet.*;
    import java.io.IOException;
    
    /**
     * @Author wly
     * @Date 2018/6/14 10:54
     */
    public class DFilter implements Filter {
        @Override
        public void init(FilterConfig filterConfig) throws ServletException {
    
        }
    
        @Override
        public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
            System.out.println("I'm DFilter");

        }
    
        @Override
        public void destroy() {
    
        }
    }

** EFilter**

package com.wang.sb.filter;
    
    import javax.servlet.*;
    import java.io.IOException;
    
    /**
     * @Author wly
     * @Date 2018/6/14 10:54
     */
    public class EFilter implements Filter {
        @Override

        }
    
        @Override
        public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
            System.out.println("I'm EFilter");
            filterChain.doFilter(servletRequest,servletResponse);
        }
    
        @Override
        public void destroy() {
    
        }
    }
