在springboot 配置过滤器的方法如下：

编写过滤器代码：

package com.neo.filter;import java.io.IOException;import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.http.HttpServletRequest;public class MyFilter implements Filter {  @Override  public void destroy() {  }  @Override  public void doFilter(ServletRequest srequest, ServletResponse sresponse, FilterChain filterChain)      throws IOException, ServletException {    HttpServletRequest request = (HttpServletRequest) srequest;    System.out.println("this is MyFilter,url :"+request.getRequestURI());    filterChain.doFilter(srequest, sresponse);  }  @Override  public void init(FilterConfig arg0) throws ServletException {  }}

编写加载过滤器代码：

package com.neo.conf;import org.springframework.boot.web.servlet.FilterRegistrationBean;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import com.neo.filter.MyFilter;import com.neo.filter.MyFilter2;@Configurationpublic class WebConfiguration {  @Bean  public FilterRegistrationBean registerFilter() {    FilterRegistrationBean registration = new FilterRegistrationBean();    registration.setFilter(new MyFilter());    registration.addUrlPatterns("/*");    registration.addInitParameter("paramName", "paramValue");    registration.setName("MyFilter");    registration.setOrder(1);    return registration;  }  @Bean  public FilterRegistrationBean registerFilter2() {    FilterRegistrationBean registration = new FilterRegistrationBean();    registration.setFilter(new MyFilter2());    registration.addUrlPatterns("/*");    registration.addInitParameter("paramName", "paramValue");    registration.setName("MyFilter2");    registration.setOrder(2);    return registration;  }}
