啟動器掃一下

此時訪問一下頁面就可以觀察到過濾器的信息

代碼

package com.example.demo.Filter;import lombok.extern.slf4j.Slf4j;import javax.servlet.*;import javax.servlet.annotation.WebFilter;@Slf4j@WebFilter(filterName = 'myFilter1', urlPatterns = '/*')public class MyFilter1 implements Filter { @Override public void init(FilterConfig filterConfig) throws ServletException { log.info(filterConfig.getFilterName() + ' init,過濾器初始化成功！'); } @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) { log.info('myFilter1 begin'); try { log.info('業務方法執行'); chain.doFilter(request, response); } catch (Exception e) { log.error('error!', e); } log.info('myFilter1 end'); } @Override public void destroy() { }}

啟動器

package com.example.demo;import org.mybatis.spring.annotation.MapperScan;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.web.servlet.ServletComponentScan;@SpringBootApplication(scanBasePackages = {'com.example'})@MapperScan('com.example.demo.mapper')@ServletComponentScan(basePackages = 'com.example.demo.Filter')public class Demo10Application { public static void main(String[] args) { SpringApplication.run(Demo10Application.class, args); }}
