在spring-boot中过滤顺序 [英] Filter order in spring-boot

问题描述

如何在spring-boot中指定过滤器的顺序？我需要在Spring Security过滤器之后插入我的MDC过滤器。我几乎尝试了所有东西，但我的滤镜始终是第一个这不起作用：

How can I specify order of my Filter in spring-boot? I need to insert my MDC filter after Spring Security filter. I tried almost everything but my filter was always first. This didn't work:

@Bean
@Order(Ordered.LOWEST_PRECEDENCE)
public UserInsertingMdcFilter userInsertingMdcFilter() {
    return new UserInsertingMdcFilter();
}

这也不起作用：

@Bean
public FilterRegistrationBean userInsertingMdcFilterRegistrationBean() {
    FilterRegistrationBean registrationBean = new FilterRegistrationBean();
    UserInsertingMdcFilter userFilter = new UserInsertingMdcFilter();
    registrationBean.setFilter(userFilter);
    registrationBean.setOrder(Integer.MAX_VALUE);
    return registrationBean;
}

推荐答案

来自Spring的家伙再次帮助。请参阅 https://github.com/spring-projects/spring-boot/issues/ 1640 和 https://jira.spring.io/browse/SEC-2730

Guys from Spring helped again. See https://github.com/spring-projects/spring-boot/issues/1640 and https://jira.spring.io/browse/SEC-2730

Spring Security没有在
创建的Filter bean上设置订单。这意味着，当Boot为它创建
FilterRegistrationBean时，它会获得默认顺序，即
LOWEST_PRECEDENCE。

Spring Security doesn't set an order on the Filter bean that it creates. This means that, when Boot is creating a FilterRegistrationBean for it, it gets the default order which is LOWEST_PRECEDENCE.

如果你想要自己的过滤掉Spring Security后你可以
为Spring Security的过滤器创建自己的注册，并指定
订单。

If you want your own Filter to go after Spring Security's you can create your own registration for Spring Security's filter and specify the order.

所以我的问题的答案是：

So the answer to my question is:

@Bean
public FilterRegistrationBean securityFilterChain(@Qualifier(AbstractSecurityWebApplicationInitializer.DEFAULT_FILTER_NAME) Filter securityFilter) {
    FilterRegistrationBean registration = new FilterRegistrationBean(securityFilter);
    registration.setOrder(Integer.MAX_VALUE - 1);
    registration.setName(AbstractSecurityWebApplicationInitializer.DEFAULT_FILTER_NAME);
    return registration;
}

@Bean
public FilterRegistrationBean userInsertingMdcFilterRegistrationBean() {
    FilterRegistrationBean registrationBean = new FilterRegistrationBean();
    UserInsertingMdcFilter userFilter = new UserInsertingMdcFilter();
    registrationBean.setFilter(userFilter);
    registrationBean.setOrder(Integer.MAX_VALUE);
    return registrationBean;
}
