Filter order in spring-boot

Question

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(); } 

This didn't work too:

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

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 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.

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.

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; }

This was fixed in Spring Boot 1.2. The security chain now defaults to order 0.

It can also be set via properties:

security.filter-order=0 # Security filter chain order.
