Web Migrations

Favor Relative URIs

When redirecting to a login endpoint, Spring Security has favored absolute URIs in the past. For example, if you set your login page like so:spring-doc.cn

http
    // ...
    .formLogin((form) -> form.loginPage("/my-login"))
    // ...
http {
    formLogin {
        loginPage = "/my-login"
    }
}
<http ...>
    <form-login login-page="/my-login"/>
</http>

then when redirecting to /my-login Spring Security would use a Location: like the following:spring-doc.cn

302 Found
// ...
Location: https://myapp.example.org/my-login

However, this is no longer necessary given that the RFC is was based on is now obsolete.spring-doc.cn

In Spring Security 7, this is changed to use a relative URI like so:spring-doc.cn

302 Found
// ...
Location: /my-login

Most applications will not notice a difference. However, in the event that this change causes problems, you can switch back to the Spring Security 6 behavior by setting the favorRelativeUrls value:spring-doc.cn

LoginUrlAuthenticationEntryPoint entryPoint = new LoginUrlAuthenticationEntryPoint("/my-login");
entryPoint.setFavorRelativeUris(false);
http
    // ...
    .exceptionHandling((exceptions) -> exceptions.authenticaitonEntryPoint(entryPoint))
    // ...
LoginUrlAuthenticationEntryPoint entryPoint = LoginUrlAuthenticationEntryPoint("/my-login")
entryPoint.setFavorRelativeUris(false)

http {
    exceptionHandling {
        authenticationEntryPoint = entryPoint
    }
}
<http entry-point-ref="myEntryPoint">
    <!-- ... -->
</http>

<b:bean id="myEntryPoint" class="org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint">
    <b:property name="favorRelativeUris" value="true"/>
</b:bean>

PortResolver

Spring Security uses an API called PortResolver to provide a workaround for a bug in Internet Explorer. The workaround is no longer necessary and can cause users problems in some scenarios. For this reason, Spring Security 7 will remove the PortResolver interface.spring-doc.cn

To prepare for this change, users should expose the PortResolver.NO_OP as a Bean named portResolver. This ensures that the PortResolver implementation that is used is a no-op (e.g. does nothing) which simulates the removal of PortResolver. An example configuration can be found below:spring-doc.cn

@Bean
PortResolver portResolver() {
	return PortResolver.NO_OP;
}
@Bean
open fun portResolver(): PortResolver {
    return PortResolver.NO_OP
}
<util:constant id="portResolver"
    static-field="org.springframework.security.web.PortResolver.NO_OP">

Use PathPatternRequestMatcher by Default

In Spring Security 7, AntPathRequestMatcher and MvcRequestMatcher are no longer supported and the Java DSL requires that all URIs be absolute (less any context root). At that time, Spring Security 7 will use PathPatternRequestMatcher by default.spring-doc.cn

To check how prepared you are for this change, you can publish this bean:spring-doc.cn

@Bean
PathPatternRequestMatcherBuilderFactoryBean requestMatcherBuilder() {
	return new PathPatternRequestMatcherBuilderFactoryBean();
}
@Bean
fun requestMatcherBuilder(): PathPatternRequestMatcherBuilderFactoryBean {
    return PathPatternRequestMatcherBuilderFactoryBean()
}
<b:bean class="org.springframework.security.config.web.PathPatternRequestMatcherBuilderFactoryBean"/>

This will tell the Spring Security DSL to use PathPatternRequestMatcher for all request matchers that it constructs.spring-doc.cn

In the event that you are directly constructing an object (as opposed to having the DSL construct it) that has a setRequestMatcher method. you should also proactively specify a PathPatternRequestMatcher there as well.spring-doc.cn

Migrate exitUserUrl and switchUserUrl Request Matchers in SwitchUserFilter

SwitchUserFilter, constructs an AntPathRequestMatcher in its setExitUserUrl and setSwitchUserUrl methods. This will change to use PathPatternRequestMatcher in Spring Security 7.spring-doc.cn

To prepare for this change, call setExitUserMatcher and setSwithcUserMatcher to provide this PathPatternRequestMatcher in advance. That is, change this:spring-doc.cn

SwitchUserFilter switchUser = new SwitchUserFilter();
// ... other configuration
switchUser.setExitUserUrl("/exit/impersonate");
val switchUser = SwitchUserFilter()
// ... other configuration
switchUser.setExitUserUrl("/exit/impersonate")

to this:spring-doc.cn

SwitchUserFilter switchUser = new SwitchUserFilter();
// ... other configuration
switchUser.setExitUserMatcher(PathPatternRequestMatcher.withDefaults().matcher(HttpMethod.POST, "/exit/impersonate"));
val switchUser = SwitchUserFilter()
// ... other configuration
switchUser.setExitUserMatcher(PathPatternRequestMatcher.withDefaults().matcher(HttpMethod.POST, "/exit/impersonate"))

Migrate filterProcessingUrl Request Matcher in AbstractAuthenticationProcessingFilter Implementations

Spring Security 6 converts any processing endpoint configured through setFilterProcessingUrl to an AntPathRequestMatcher. In Spring Security 7, this will change to PathPatternRequestMatcher.spring-doc.cn

If you are directly invoking setFilterProcessingUrl on a filter that extends AbstractAuthenticationProcessingFilter, like UsernamePasswordAuthenticationFilter, OAuth2LoginAuthenticationFilter, Saml2WebSsoAuthenticationFilter, OneTimeTokenAuthenticationFilter, or WebAuthnAuthenticationFilter, call setRequiredAuthenticationRequestMatcher instead to provide this PathPatternRequestMatcher in advance.spring-doc.cn

That is, change this:spring-doc.cn

UsernamePasswordAuthenticationFilter usernamePassword = new UsernamePasswordAuthenticationFilter(authenticationManager);
usernamePassword.setFilterProcessingUrl("/my/processing/url");
val usernamePassword = UsernamePasswordAuthenticationFilter(authenticationManager)
usernamePassword.setFilterProcessingUrl("/my/processing/url")

to this:spring-doc.cn

UsernamePasswordAuthenticationFilter usernamePassword = new UsernamePasswordAuthenticationFilter(authenticationManager);
RequestMatcher requestMatcher = PathPatternRequestMatcher.withDefaults().matcher("/my/processing/url");
usernamePassword.setRequest(requestMatcher);
val usernamePassword = UsernamePasswordAuthenticationFilter(authenticationManager)
val requestMatcher = PathPatternRequestMatcher.withDefaults().matcher("/my/processing/url")
usernamePassword.setRequest(requestMatcher)
Most applications use the DSL instead of setting the `filterProcessingUrl` directly on a filter instance.

Migrate CAS Proxy Receptor Request Matcher

Spring Security 6 converts any configured proxyReceptorUrl to a request matcher that matches the end of the request, that is /**/proxy/receptor. In Spring Security 7, this pattern is not allowed and will change to using PathPatternRequestMatcher. Also in Spring Security 7m the URL should by absolute, excluding any context path, like so: /proxy/receptor.spring-doc.cn

So to prepare for these change, you can use setProxyReceptorRequestMatcher instead of setProxyReceptorUrl.spring-doc.cn

That is, change this:spring-doc.cn

casAuthentication.setProxyReceptorUrl("/proxy/receptor");
casAuthentication.setProxyReceptorUrl("/proxy/receptor")

to this:spring-doc.cn

casAuthentication.setProxyReceptorUrl(PathPatternRequestMatcher.withDefaults().matcher("/proxy/receptor"));
casAuthentication.setProxyReceptorUrl(PathPatternRequestMatcher.withDefaults().matcher("/proxy/receptor"))

Migrate your WebInvocationPrivilegeEvaluator

If you are using Spring Security’s JSP Taglibs or are using WebInvocationPrivilegeEvaluator directly, be aware of the following changes:spring-doc.cn

  1. RequestMatcherWebInvocationPrivilegeEvaluator is deprecated in favor of AuthorizationManagerWebInvocationPrivilegeEvaluatorspring-doc.cn

  2. HandlerMappingIntrospectorRequestTransformer is deprecated in favor of PathPatternRequestTransformerspring-doc.cn

If you are not constructing these directly, you can opt-in to both changes in advance by publishing a PathPatternRequestTransformer like so:spring-doc.cn

@Bean
HttpServletRequestTransformer pathPatternRequestTransformer() {
	return new PathPatternRequestTransformer();
}
@Bean
fun pathPatternRequestTransformer(): HttpServletRequestTransformer {
    return PathPatternRequestTransformer()
}
<b:bean class="org.springframework.security.web.access.PathPatternRequestTransformer"/>

Spring Security will take this as a signal to use the new implementations.spring-doc.cn

One difference you may notice is that `AuthorizationManagerWebPrivilegeInvocationEvaluator` allows the authentication to be `null` if the authorization rule is `permitAll`.

Test your endpoints that `permitAll` in case JSP requests using this same require should not, in fact, be permitted.

Include the Servlet Path Prefix in Authorization Rules

For many applications the above will make no difference since most commonly all URIs listed are matched by the default servlet.spring-doc.cn

However, if you have other servlets with servlet path prefixes, then these paths now need to be supplied separately.spring-doc.cn

For example, if I have a Spring MVC controller with @RequestMapping("/orders") and my MVC application is deployed to /mvc (instead of the default servlet), then the URI for this endpoint is /mvc/orders. Historically, the Java DSL hasn’t had a simple way to specify the servlet path prefix and Spring Security attempted to infer it.spring-doc.cn

Over time, we learned that these inference would surprise developers. Instead of taking this responsibility away from developers, now it is simpler to specify the servlet path prefix like so:spring-doc.cn

PathPatternRequestParser.Builder servlet = PathPatternRequestParser.servletPath("/mvc");
http
    .authorizeHttpRequests((authorize) -> authorize
        .requestMatchers(servlet.pattern("/orders/**").matcher()).authenticated()
    )

For paths that belong to the default servlet, use PathPatternRequestParser.path() instead:spring-doc.cn

PathPatternRequestParser.Builder request = PathPatternRequestParser.path();
http
    .authorizeHttpRequests((authorize) -> authorize
        .requestMatchers(request.pattern("/js/**").matcher()).authenticated()
    )

Note that this doesn’t address every kind of servlet since not all servlets have a path prefix. For example, expressions that match the JSP Servlet might use an ant pattern /*/.jsp.spring-doc.cn

There is not yet a general-purpose replacement for these, and so you are encouraged to use RegexRequestMatcher, like so: regexMatcher("\\.jsp$").spring-doc.cn

For many applications this will make no difference since most commonly all URIs listed are matched by the default servlet.spring-doc.cn

Use RedirectToHttps Instead of Channel Security

Years ago, HTTPS at large was enough of a performance and configuration concern that applications wanted to be able to decide which segments of an application would require HTTPS.spring-doc.cn

requires-channel in XML and requiresChannel in Java Config allowed configurating an application with that in mind:spring-doc.cn

http
    .requiresChannel((channel) -> channel
        .requestMatchers("/secure/**").requiresSecureChannel()
        .requestMatchers("/insecure/**").requiresInsecureChannel()
    )
http {
    requiresChannel {
        secure("/secure/**")
        seccure("/insecure/**", "REQUIRES_INSECURE_CHANNEL")
    }
}
<http>
    <intercept-url pattern="/secure/**" access="authenticated" requires-channel="REQUIRES_SECURE_CHANNEL"/>
    <intercept-url pattern="/insecure/**" access="authenticated" requires-channel="REQUIRES_INSECURE_CHANNEL"/>
</http>

Modern applications should either always require HTTPS. However, there are times, like when developing locally, when one would like the application to use HTTP. Or, you may have continuing circumstances that require part of your application to be HTTP.spring-doc.cn

In any case, you can migrate to redirect-to-https-request-matcher-ref and redirectToHttps by first constructing a RequestMatcher that contains all circumstances where redirecting to HTTPS is needed. Then you can reference that request matcher like so:spring-doc.cn

http
    .redirectToHttps((https) -> https.requestMatchers("/secure/**"))
    // ...
var secure: RequestMatcher = PathPatternRequestMatcher.withDefaults().pattern("/secure/**")
http {
    redirectToHttps {
        requestMatchers = secure
    }
    // ...
}
<b:bean id="builder" class="org.springframework.security.web.servlet.util.matcher.PathPatternRequestMatcher$Builder"/>
<b:bean id="secure" class="org.springframework.security.web.servlet.util.matcher.PathPatternRequestMatcher" factory-bean="builder" factory-method="matcher">
    <b:constructor-arg value="/secure/**"/>
</b:bean>
<http redirect-to-https-request-matcher-ref="secure">
    <intercept-url pattern="/secure/**" access="authenticated"/>
    <intercept-url pattern="/insecure/**" access="authenticated"/>
    <!-- ... -->
</http>

If you have several circumstances where HTTP is needed, consider using OrRequestMatcher to combine them into a single RequestMatcher instance.spring-doc.cn
