1.public class Logfilter implements Filter{
private Logger logger= LoggerFactory.getLogger(Logfilter.class); @Override public void init(FilterConfig filterConfig) throws ServletException { } @Override public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException { filterChain.doFilter(servletRequest,servletResponse); } @Override public void destroy() { }
}
建立自定義filter類實現filter介面並實現三個方法

public class FilterBeanConfig {
/**
* 1.構造filter
* 2.配置連線url
* 3.利用 FilterRegistrationBean 進行包裝
* @return
/
@Bean//自動會識別為spring管理的bean
public FilterRegistrationBean logFilter(){
FilterRegistrationBean filterRegistrationBean=new FilterRegistrationBean();
filterRegistrationBean.setFilter(new Logfilter());//新增過濾器
ArrayList urList = new ArrayList<>();
urList.add("
filterRegistrationBean.setUrlPatterns(urList);//設定過濾器路徑
return filterRegistrationBean;
}
}
