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;
@Configuration
public 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;
}
