我要评论写一个继承类
启动器扫一下
此时访问一下页面就可以观察到过滤器的信息
代码
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,过滤器初始化成功！");
}
@override
public void dofilter(servletrequest request, servletresponse response, filterchain chain) {
log.info("myfilter1 begin");
try {
log.info("业务方法执行");
chain.dofilter(request, response);
} catch (exception e) {
log.error("error!", e);
}
log.info("myfilter1 end");
}
@override
public void destroy() {
}
}
启动器
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);
}
}
结果
