SpringBoot 自定义 Filter 不生效的原因之一：未注册过滤器

SpringBoot 自定义 Filter 不生效的原因之一就是未注册过滤器，需要在 Application 上添加下面的注解

@ServletComponentScan(basePackages = "cn.twle.java.demo.demo.filters")

例如

package cn.twle.java.demo.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@ComponentScan("cn.twle.java.demo.demo")
@SpringBootApplication(exclude = {
        org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class
})

@ServletComponentScan(basePackages = "cn.twle.java.demo.demo.filters")
public class DemoApplication {

    public static void main(String[] args) {

        SpringApplication.run(DemoApplication.class, args);
    }
}
