先写配置文件类

FilterConfig.java

package com.ty.tyzxtj.config;

import javax.servlet.Filter;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.ty.tyzxtj.fiter.SessionFilter;

/**
 * 过滤器配置
 * @author wangjiping

 */
@Configuration
public class FilterConfig {
    /**
     * 配置过滤器
     * @return
     */
    @Bean
    public FilterRegistrationBean someFilterRegistration() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(sessionFilter());
        registration.addUrlPatterns("/*");
        registration.addInitParameter("paramName", "paramValue");
        registration.setName("sessionFilter");
        return registration;
    }

    /**
     * 创建一个bean
     * @return
     */
    @Bean(name = "sessionFilter")
    public Filter sessionFilter() {
        return new SessionFilter();
    }
}
