spring boot过滤器FilterRegistrationBean实现方式

public class Test1Filter implements Filter {

  @Override
  public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain arg2)
      throws IOException, ServletException {
    // TODO Auto-generated method stub
    HttpServletRequest request=(HttpServletRequest)arg0;
    System.out.println("自定义过滤器filter1触发,拦截url:"+request.getRequestURI());
    arg2.doFilter(arg0,arg1);
  }

}

public class Test2Filter implements Filter {
  @Override
  public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain arg2)
      throws IOException, ServletException {
    // TODO Auto-generated method stub
    HttpServletRequest request=(HttpServletRequest)arg0;
    System.out.println("自定义过滤器filter2触发,拦截url:"+request.getRequestURI());
    arg2.doFilter(arg0,arg1);
  }

}
