配置多个过滤器
@Configuration
public class FilterConfig {
@Bean
public FilterRegistrationBean registFilter(){
FilterRegistrationBean registration = new FilterRegistrationBean();
//配置认证过滤器
registration.setFilter(new CASFilterExtend());
registration.setName("CAS Filter");
//设置过滤器的参数
registration.addInitParameter("casserverLoginIP","192.168.1.128:8080");
registration.addUrlPatterns("/*");
//设置优先级
registration.setOrder(9);
return registration;
}
@Bean
public FilterRegistrationBean testFilter(){
FilterRegistrationBean registration = new FilterRegistrationBean();
//测试的过滤器
registration.setFilter(new MyTestFilter());
registration.addUrlPatterns("/*");
registration.setOrder(3);
return registration;
}
}
- 过滤器的优先级
数字越低优先级越高
- 自定义过滤器
通过实现Filter接口 在doFilter中进行过滤条件设置
public class MyTestFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
System.out.println("进入测试过滤器中");
//放行
filterChain.doFilter(servletRequest,servletResponse);
}
@Override
public void destroy() {
}
}
